Description

Printing equipment, printing process and image processing apparatus, image processing method

Technical field

The present invention relates to the printing equipment etc. of the printer etc. of facsimile machine device or duplicator, OA machine, be particularly related to carrying out particulate with the polychrome liquid ink and shoot out literal or image at printing (recording materials), delineation of predetermined, i.e. suitable printing equipment, print routine, printing process and image processing apparatus, image processing program, the image processing method of the printing treatment of so-called ink-jetting style and the storage medium that stores said procedure.

Background technology

Below, to printing equipment, particularly adopt the printer (below become ' ink-jet printer ') of ink jet type to be illustrated.

Ink-jet printer as a rule because price is low and can easily obtain high-quality chromatograp, is therefore followed popularizing of personal computer or digital camera etc., just in office but spread to the general user.

Such a ink-jet printer, in general, by the integrated moving body that is called as balladeur train (carriage) with print cartridge and printhead, the limit comes and goes on the vertical direction of the paper feeding direction of relative printed medium (use paper) and moves, the limit is gone up to printed medium (using paper) by the nozzle of its printhead and is shootd out the particle that (injection) goes out liquid ink with point-like, thus on printed medium the literal of delineation of predetermined or image to finish desired printed matter.In addition, by in this balladeur train, possessing the four look (Huangs that comprise black (black), fuchsin, green grass or young crops) print cartridge and separately printhead of all kinds, not only black and white printing, and can easily make up full color printing of all kinds and (more had, on these color basis, increase the also practicability of colored printing of 6 looks, 7 looks or 8 looks of shallow green grass or young crops or shallow fuchsin etc.).

Also have, printing on the balladeur train comes and goes the ink-jet printer that the type of printing is carried out on the operation limit at relative paper feeding direction in front on vertical direction like this, it is tens of inferior so that more than 100 times to make printhead come and go operation in order clearly to print on a whole page or leaf, with the printing equipment of other modes, use the laser printer of electrofax technology to compare, has time-consuming defective of wanting such as classes such as duplicators for this reason.

Corresponding this, be equipped with the rectangular printhead of identical with the printing width (perhaps also long) size and do not use the type ink-jet printer of balladeur train, needn't on the width of printing, move, be the printing of so-called single pass (1 time by) owing to can realize printhead, therefore can reach the high speed printing identical with the aforementioned laser printer.In addition, owing to do not need to carry the balladeur train of printhead and the drive system that moves it, thus can be achieved as follows advantage: the miniaturization of printer framework, lightweight also have quietness also to be greatly improved.In addition, generally the ink-jet printer with preceding a kind of mode is called " repeatedly by type (マ Le チパス) printer ", and the ink-jet printer of a kind of mode in back is called " line head dummy (ラィ Application ヘッ De) printer ".

; indispensable printhead in the such a ink-jet printer; since be with diameter be about 10～70 μ m fine nozzle with certain being spaced be 1 row; and set on print direction that multiple row constitutes; therefore; may shoot out direction owing to foozle causes the ink of a part of nozzle; perhaps the position of nozzle is configured in the position that is offset to some extent with ideal position; its result; drippage position by these nozzles formed picture point on printed medium also can be departed to some extent with ideal position, promptly can produce so-called " flight deflection phenomenon ".In addition, because the bias property of nozzle,, then can cause quantity of ink to compare the generation of situation such as too much or very few with desired quantity if this deviation is very big.

As a result, use the printed part of this bad nozzle, the printing that will produce so-called being called as " fringe phenomena (muscle) " is bad, has significantly reduced press quality.In addition, if the distance that " flight deflection phenomenon " has taken place then shootd out by adjacent nozzle between the picture point that also can be inhomogeneous, the distance part longer than normal condition of closing between picture point will produce " informal voucher line (when printing is white) ", and the distance of closing between picture point will produce " dark striped " in short-term than normal condition.Also have, if when the value of quantity of ink departs from ideal value, the nozzle that quantity of ink is many can produce dark striped, and the part that quantity of ink is few can produce the informal voucher line.

Particularly, this fringe phenomena, described with the front " repeatedly by the type printer " (serial printer) compared, and " the line head printer " that printhead or printed medium are fixed (1 time by printing) is easier to take place (repeatedly by having in the type printer by utilizing printhead repeatedly to come and go the not eye-catching technology of fringe phenomena that makes).

For this reason, bad in order to prevent as mentioned above the printing that " fringe phenomena " cause, need raising, design improvement of the manufacturing technology of printhead etc., the research and development of so-called hardware components are paid attention to be launched, but owing to manufacturing cost, technological side etc. are difficult to provide 100% printhead that does not produce " fringe phenomena ".

Thus, present except the improvement that the described such hardware in front divides, also have and reduce the technology of this " fringe phenomena " with printing control as follows, i.e. what is called use software approach.

Such as, in patent document 1 grade below, when quantizing the multi-grayscale image, make picture point concentrate low, the middle concentration part that is created in the multi-grayscale image by having implemented to carry out dithering process (dither) after error diffusion is handled, and disperse to produce picture point at the periphery of having concentrated picture point in the high concentration part, partly there is not blank image in high concentration especially by such formation.

But, in aforesaid prior art,, in general be difficult to reduce fringe phenomena in fringe phenomena very showy middle concentration part or low concentration part although can reduce fringe phenomena in the high concentration part.In addition, because very obvious concentrating of middle concentration part or low concentration part picture point, thus might make the graininess effect obviously reduce picture quality.

In addition, in dithering process, owing to generally be that threshold value with dither matrix is that rise/stops and sets the concentration value that is transfused to image on the boundary, the input concentration value has the particularly characteristic of the half tone reproduction difference of level (gradation) thus with to export concentration value inconsistent sometimes.

Patent documentation 1: the spy opens the 2001-177722 communique.

As shown in the figure, this printing equipment 100 mainly is made of following: the view data that obtains multivalue image data obtains mechanism 10; To obtain the view data division mechanism 12 that view data that mechanism 10 obtains is divided into each pixel area by this view data; The pixel area concentration value of total that calculates the concentration value of each pixel in the described pixel area of being cut apart by this view data division mechanism 12 adds up to calculation mechanism 14; Store the pixel area picture point that the pixel area picture point that adds up to the total concentration value of the described pixel area that calculation mechanism 14 calculates and expression to constitute corresponding to the picture point of the total concentration value of this pixel area by this pixel area concentration value constitutes table 400 and constitute table storing mechanism 16; The picture point that calculates the formation that is configured in the picture point in the described pixel area according to this pixel area picture point formation table 400 constitutes calculation mechanism 18; Store expression and be configured in the picture point configuration sequence table storing mechanism 20 of picture point configuration sequence table 500 of the configuration sequence of the picture point in the described pixel area; The configuration sequence of represented picture point in the picture point configuration sequence table 500 according to this picture point configuration sequence table storing mechanism 20, will constitute the picture point that calculation mechanism 18 calculates by described picture point and constitute the picture point collocation mechanism 22 that is configured in the described pixel area; The printed data that will be synthesized, be generated printed data by described each pixel area that this picture point collocation mechanism 22 has disposed picture point generates mechanism 24; Implement the ink jet printer structure 26 of printing according to the printed data that generates mechanism's 24 generations by this printed data; Printhead 200 with these printing mechanism's 26 uses.

At first, to being applicable to that printhead 200 of the present invention describes.

Fig. 3 represents the part amplification inclinating view of the mechanism of this printhead 200, and Fig. 4 is this part amplification view.

As shown in Figure 3, the employed rectangular structure that extends at the paper cross direction of printing in the printer that this printhead 200 is so-called line head dummys, be by black nozzles module 50, yellow nozzle module 52, carmetta nozzle module 54 and cyan nozzle module 56 these 4 kinds of nozzle modules 50,52,54,56 go up at paper feeding direction (sub scanning direction) and overlappingly to come integrated arrangement to constitute, wherein black nozzles module 50 is to arrange linearly formation by a plurality of nozzle N that shoot out black (K) ink that are exclusively used on main scanning direction, yellow nozzle module 52 is to arrange linearly formation by a plurality of nozzle N that shoot out yellow (Y) ink that are exclusively used on same main scanning direction, carmetta nozzle module 54 is to arrange linearly formation by a plurality of nozzle N that shoot out carmetta (M) ink that are exclusively used on same main scanning direction, and cyan nozzle module 56 is to arrange linearly formation by a plurality of nozzle N that shoot out cyan (C) ink that are exclusively used on same main scanning direction.In addition, also have with the black and white and be only to use black (K) nozzle module under the situation of printhead of purpose or be use 6 looks that increase the nozzle module that is exclusively used in inks such as shooing out shallow fuchsin, dark green grass or young crops under the situation of the printhead of target, the situation of 7 chromatic inks with high quality image.Also have, because the number of 1 nozzle that nozzle module had, according to its resolution ratio and different, therefore the nozzle number is not particularly limited, such as, the what is called that the back is told about is repeatedly by under the situation of type, about nearly " 180 " are individual, and under the situation of line head, mostly be about 1,000 hundreds ofs.

Then, as Fig. 4 be see from the side such as figure as a black nozzles module 50 in these four

nozzle modules

50,52,54,56, be expressed as follows state: a left side is played the 6th nozzle N6 and is produced the flight deflection phenomenon and shoot out ink from these nozzle 6 adippings, causes near printing (ink drippage) picture point normal nozzles N7 by it.

Therefore, implement printing if use this black nozzles module 50, then with shown in Figure 5 under the curve state that do not fly, the situation (desirable zag image point patterns) that all is printed on the print position of regulation of any picture point compares, such as the 6th nozzle N6 produces the flight deflection phenomenon from a left side, the print position of its picture point and target print position are offset, print to the normal nozzles N7 on its next door with distance a as a result as shown in Figure 6.

In addition, in the example of Fig. 4 and Fig. 6, for the ease of understanding explanation flight deflection phenomenon, only the situation that the flight deflection phenomenon taken place 1 nozzle is illustrated, in the printhead of reality, in general what all can produce the flight deflection phenomenon as the back will be told about.Also have, the characteristic of this printhead 200 is just to be fixed in the fabrication stage to a certain extent, can think if get rid of shooing out of ink obstruction etc. bad outside, changed after being difficult in manufacturing.

Have again, the zag image point patterns of Fig. 5 and Fig. 6, be to have represented only by the formed example of the picture point of a kind of size for the ease of understanding explanation flight deflection phenomenon, but it is well-known, owing to this image spot size and combination, be its part concentration, even in identical flight deflection amount, the significance degree of its fringe phenomena also has very big-difference.Also promptly, this fringe phenomena in general, known have a following characteristic: be difficult to manifest in the high or low part of concentration, and be easy to show under intermediate concentration.In addition, because the color of ink also can make a difference, under dark colours such as black, be easy to performance, and under light colours such as yellow, shallow green grass or young crops, shallow fuchsin, relatively be not easy to manifest.

Then, view data obtains mechanism 10 following function is provided, promptly; Jie obtains many-valued (M value) color image data for printing usefulness of sending here from the printing instruction device (not shown) of computer (PC) that is connected with this printing equipment 10 and printing server etc. by network etc., and perhaps image (data) reading devices such as the scanner of not representing from figure, CD-ROM drive directly read and obtain view data.Also have, it also brings into play following effect simultaneously, if the RGB data that the many-valued color image data of that is: obtaining is not many-valued, when being the view data that is showed by 8 (bit), 256 tonal gradations respectively such as shades of colour in each pixel (R, G, B) gray scale (brightness value) separately, it is carried out colour switching handle, be transformed to the many-valued CMYK corresponding (under the 4 pornographic conditions) data with each ink of aforementioned printhead 200.

Following view data division mechanism 12 provides following function: will obtain the view data that mechanism 10 obtains by this view data and be divided into a plurality of zones at each predetermined pixel area.

Here, cut size as the pixel area of cutting apart by this view data division mechanism 12, not special the qualification, its cut size is more little, the influence that brings picture quality is more little and can obtain the print product of high image quality, with respect to this, can think that its information processing capacity becomes very big, increase the processing time, and the scale of looking striped may be able to not be avoided these fully, therefore can think that such as the size that (under the situation of color image data, is each color) about 8 * 8 pixels (pixel) be only.

Thus, such as, when obtaining mechanism's 10 obtained view data and be 720 * 720 pixels, it is divided into " 225 ((720 * 720)/(8 * 8)) " pixel area by described view data.In addition, the cut size of the pixel area that is undertaken by this view data division mechanism 12, so long as the size that can constitute in pixel area picture point formation table 400 as the back is described just can be not limited to 1 type, and can adopt polytype simultaneously.

Below, the pixel area concentration value adds up to calculation mechanism 14 that the function of the total of the concentration value that calculates each pixel in each pixel area of being cut apart by this view data division mechanism 12 is provided.Promptly, such as, the number of picture elements of each pixel area is that " 64 (8 * 8) " pixel, concentration value separately are that 8 (bit) 256 (0～255) tonal gradation is represented as previously mentioned,, be to go out the total concentration value of its pixel area then in " 0 (0 * 64) "～" 16320 (256 * 64) " range computation by adding up to the concentration value of all each pixels.In addition, as previously mentioned, when this view data is color image data, be the total concentration value that calculates its pixel area by each color.

Below, pixel area picture point formation table storing mechanism 16 stores more than one expressions at least and adds up to the total concentration value of each pixel area that calculation mechanism 14 calculates and the pixel area picture point that the picture point corresponding with the total concentration value of this pixel area constitutes to constitute table 400 by this pixel area concentration value, reads predetermined pixel area picture point formation table 400 as required and is utilized.

That Fig. 8～Figure 15 represents is the figure of an example of this pixel area picture point formation table 400.What Fig. 8 represented is the typical example of this pixel area picture point formation table 400a, and what Fig. 9～Figure 15 represented respectively in addition is the specific example of this pixel area picture point formation table 400b.

Promptly, this pixel area picture point constitutes the total concentration value of table 400 according to each pixel (pixel) in the pixel area, regulation is arranged on the setting picture point ratio in this pixel area, and concrete regulation adds up to picture point number, its picture point kind (image spot size) and this number of dots that should set picture point ratio actual disposition.

Such as, as shown in Figure 8, the pixel area picture point constitutes table (pixel area 8 * 8,4 tonal gradations) be expressed as follows among the 400a: during the concentration value average out to of each pixel (pixel) in pixel area " 0 (8 (bit); 256 tonal gradations) ", total pixel value in its pixel area is " 0 ", its picture point ratio, the actual image point number, actual image point number total all is respectively " 0 ", and during the concentration value average out to " 30 (being all 8 (bit); 256 tonal gradations) " of each pixel (pixel) in the pixel area, total pixel value in its pixel area is " 1920 (30 * 64) ", its ratio of setting the picture point that the picture point ratio is the L size (big picture point) is " 0 ", the ratio of the picture point of M size (middle picture point) is " 0 ", the ratio of the picture point of S size (little picture point) is " 1 ", its actual image point number is that L size picture point and M size picture point are respectively " 0 ", only S size picture point is " 23 ", and the total of its number of dots also is " 23 ".That is, as mentioned above, during the concentration value average out to " 30 " of each elementary area, only show total concentration in this pixel area by the picture point of 23 S sizes.

In addition, as shown in the drawing, when the concentration value average out to " 70 (being all 8 (bit), 256 tonal gradations) " of each pixel (pixel) in this pixel area, total pixel value in its pixel area is " 4480 (70 * 64) ", it sets picture point ratio is that the ratio of L size picture point is " 1 " for the ratio of " 0 ", M size picture point for the ratio of " 1 ", S size picture point, its actual image point number is that L is of a size of that " 0 ", M are of a size of " 18 ", S is of a size of " 17 ", and the adding up to of its number of dots " 35 ".That is, as mentioned above, during the concentration value average out to " 70 " of each elementary area, this adds up to 35 picture points to show total concentration in this pixel area by the picture point of 18 M sizes with number 17 S size picture points about equally of this M size picture point.

Also have, equally, during the concentration value average out to of each pixel (pixel) in pixel area " 125 (being all 8 (bit); 256 tonal gradations) ", total pixel value in its pixel area is " 8000 (125 * 64) ", the ratio that its setting picture point ratio is a L size picture point is " 1 ", the ratio of M size picture point is " 1 ", the ratio of S size picture point is " 1 ", its actual image point number is that L size picture point is " 16 ", M size picture point is " 15 ", S size picture point be " 16; all about equally, roughly 3 times " 47 " that add up to each picture point number of its number of dots.That is, as mentioned above, during the concentration value average out to " 125 " of each elementary area, the setting picture point ratio of each picture point of L, M, S size and actual image point number show total concentration in this pixel area by the picture point of these each sizes all about equally.

Then, each interior pixel concentration value of time its pixel area that the pixel area picture point formation table 400b of Fig. 9～Figure 15 represents is come the mean intensity value of the constituent parts pixel under the expression situation to be the complete pattern till " 0 "～" 255 " by 8 (bit), 256 tonal gradations, by like this, under the situation that the concentration value of each pixel in its pixel area is represented by 8 (bit), 256 tonal gradations, can inevitable mechanically select one of them.

What Fig. 7 represented is the picture point size of each picture point in this pixel area and the relation between the concentration value (8 (bit), 256 tonal gradations), if the picture point kind has been represented the picture point size and the concentration value of each picture point kind for comprising " no picture point " in interior 4 kinds (picture point kind numbering " 0 "～" 3 ") in the table.That is, image spot size was " a no picture point " when the picture point kind was numbered " 0 ", and its concentration value is " 0 ", and image spot size was " S size (a little picture point) " when the picture point kind was numbered " 1 ", and its concentration value is " 85 ".In addition, image spot size was " M size (a middle picture point) " when the picture point kind was numbered " 2 ", and its concentration value is " 170 ", and image spot size was " L size (big picture point) " when the picture point kind was numbered " 3 ", and its concentration value is " 255 ".

Therefore, pixel area picture point as Fig. 8 constitutes shown in the table 400a, when the mean intensity value of constituent parts pixel is that the total concentration value of " 30 ", its pixel area is during for " 1920 ", by using " the S size picture point " of 23 concentration values for " 85 ", the total concentration value of its S size picture point is " 1955 (85 * 23) ", and the total concentration value of its pixel area can roughly correctly be showed.

In addition, shown in figure, when the mean intensity value of constituent parts pixel is " 125 ", the total concentration value of its pixel area is " 8000 ", by using " the S size picture point " of 16 concentration values respectively for " 85 ", 15 M size picture points that concentration value is " 170 ", 16 L size picture points that concentration value is " 255 ", the total concentration value of S size picture point is " 1360 (85 * 16) ", the total concentration value of M size picture point is " 2550 (170 * 15) ", the total concentration value of L size picture point is " 4080 (255 * 16) ", their total concentration value is " 7990 ", and the total concentration value (8000) of this pixel area can roughly correctly be showed.

Below, picture point constitutes calculation mechanism 18 provides the function that calculates the formation that is configured in the picture point in the described pixel area according to this pixel area picture point formation table 400.Promptly, such as the concentration value of each pixel in aforementioned each pixel area add up to " 4100 " time, pixel area picture point with reference to Figure 10 constitutes table 400b, because the mean intensity value shown in the arrow (※ 1) is that total concentration value and this actual concentrations aggregate value of project of " 64 " is the most approaching among the figure, therefore according to this project, try to achieve composition and the actual image point number of setting picture point.Its result, when the concentration value of each pixel in aforementioned each pixel area adds up to " 4100 ", because the composition of its picture point is a L size picture point " 0 ": M size picture point " 1 ": S size picture point " 1 " therefore calculates following formation: 16 M size picture points and 16 S size picture points (picture point adds up to concentration value=" 4080 ") are configured in the described pixel area.

Also have, the concentration value of each pixel in aforementioned each pixel area add up to " 10500 " time, pixel area picture point with reference to Figure 13 constitutes table 400b, because the mean intensity value shown in the arrow (※ 2) is that total concentration value and this actual concentrations aggregate value of project of " 164 " is the most approaching among the figure, therefore according to this project, try to achieve composition and the actual image point number of setting picture point.Its result, when the concentration value of each pixel in aforementioned each pixel area adds up to " 10500 ", because the composition of its picture point is a L size picture point " 2 ": M size picture point " 2 ": S size picture point " 1 " therefore calculates following formation: 22 L size picture points, 23 M size picture points and 11 S size picture points (picture point adds up to concentration value=" 10455 ") are configured in the described pixel area.

In addition, Cmax value under the situation that the concentration value of each pixel in such pixel area is showed by 8 (bit), 256 tonal gradations is, shown in arrow among the figure (※ 3), mean intensity value is that the total concentration value of the project of " 255 " is " 16320 ", because its picture point composition is a L size picture point " 1 ": M size picture point " 0 ": S size picture point " 0 ", so calculate the result that all pixels are made of L size picture point.

Also have, in the later table of Fig. 9, add up to concentration value just to be showed dispersedly, but much less,, then do not need interpolation calculation if add up to concentration value table itself to talk about in more detail again.Promptly, do not need to select to add up to the actual image point number of concentration value and the immediate value of actual concentrations aggregate value, and can be directly with reference to the actual image point number from table, therefore in order to try to achieve composition and the actual image point number of setting picture point, except the method for aforesaid " selecting immediate actual image point number ", also has the method for " from table directly with reference to the actual image point number ".

Below, picture point configuration sequence table storing mechanism 20 is constructed as follows: store the picture point configuration sequence table 500 that a kind of expression is configured in the configuration sequence of the picture point in the described pixel area at least, and can read, utilize predetermined picture point configuration sequence table 500 as required.

Then, picture point collocation mechanism 22 provides following function: the configuration sequence of represented picture point in the picture point configuration sequence table 500 according to this picture point configuration sequence table storing mechanism 20, will constitute picture point that calculation mechanism 18 calculates by described picture point and constitute and be configured in the described pixel area.

In the present embodiment, store two kinds of picture point configuration sequence table 500a, 500b as shown in Figure 16 (A) and Figure 17 in this picture point configuration sequence table storing mechanism 20, read one of these two kinds of picture point configuration sequence table 500a, 500b or two kinds as required and all read, and be used in each unit area respectively.

That is, each component of the picture point configuration sequence table 500a shown in Figure 16 (A) is corresponding to each pixel of described unit area, the numeral of each component be the configuration sequence of picture point.Therefore picture point collocation mechanism 22 is according to 16 L size picture points of picture point configuration sequence table 500a configuration of this Figure 16 (A), 15 M size picture points, 15 S size picture points (picture point composition " 1 ": " 1 ": " 1 "), its result, shown in figure (B), the middle body that picture point is configured in this pixel area is in the ellipse that tilted direction tilts to the right of center.In addition, when the numeral according to this picture point configuration sequence table 500a disposed each picture point, picture point collocation mechanism 22 was that the L size picture point from the concentration value maximum begins preferentially to be configured.

On the other hand, each component of picture point configuration sequence table 500b shown in Figure 17 too, corresponding to each pixel of described unit area, what the numeral of each component was also represented is the configuration sequence of each picture point.Therefore picture point collocation mechanism 22 is according to 16 L size picture points of the same configuration of the picture point configuration sequence table 500b of this Figure 17,15 M size picture points, 15 S size picture points (picture point composition " 1 ": " 1 ": " 1 "), its result, though do not illustrate especially, the middle body that picture point is configured in this pixel area is in the whirlpool shape figure of center.

In addition, about above-mentioned picture point configuration sequence, be that middle body with pixel area is the center configuration picture point, but said here " middle body " is meant the center of this pixel area or near the position of center.

Below, with reference to Figure 18, the method for the center of asking for pixel area is described.

Shown in figure, suppose the pixel area of 8 pixels * 8 pixels, establish each the pixel a[i in this pixel area, j] be vector (i, j) (a[i, j]=(i, j)), then from the pixel a[0 in the upper left corner of pixel area, 0] to the pixel a[7 in the lower right corner, 7] vector is represented as from (0,0) to (7,7).At this, (i, i j) are real number, and j is an imaginary number.

Like this, if try to achieve the vector value of each pixel in the pixel area, then the center of this pixel area can be asked for by following formula (1).

(formula 1)

\overset{&RightArrow;}{A} = \frac{1}{N \times M} Σ_{i = 0}^{N} Σ_{j = 0}^{M} a [i, j]

At this, substitution N=8, M=8, i=0～7, j=0～7 in the formula (1), then

The center=(0,0)+(1,0)+... + (7,7) }/(8 * 8)

＝(3.5，3.5)

Therefore, center (3.5,3.5) are the above-mentioned upper left corner a (0,0) and the position at the center of lower right corner a (7,7) as can be known, are the cores of this pixel area.

Below, printed data generates mechanism 24 following function is provided: will synthesize, generate printed data by described each pixel area that this picture point collocation mechanism 22 has disposed picture point, and send the printed data of generation to printing mechanism 26.

Printing mechanism 26 is following ink-jet printers: the limit is moved printed medium (using paper) S or printhead 200 or is moved its both sides, the limit makes each nozzle of the described

nozzle module

50,52,54,56 that is formed in the described printhead 200 that ink is ejected each picture point shape, follows in described printing and forms the predetermined picture that is made of a plurality of picture points on the S.This printing mechanism 26 except described printhead 200, the not shown known inscapes such as printing controlling organization that this printhead 200 is shootd out with the ink of Data Control printhead 200 at the not shown paper advance mechanism that not shown send head mechanism (repeatedly passing through type), is used to described printed medium S is moved that come and go to move on its width on the printed medium S, based on described printing.

In addition, be to use the form software for calculation Excel (registration mark) of Microsoft to make as this Fig. 8～pixel area picture point formation table 400 shown in Figure 15.Figure 19 is the figure of an example of these actual image point computational methods of expression, and the mode that is no more than the number of total picture element amount of pixel area with the aggregate value of various image spot sizes is set the picture point kind.

Then, if connection power supply, then be stored in the system program of BIOS among ROM64 etc. etc., perhaps all be loaded among the RAM62 by CD-ROM or the storage medium of DVD-ROM, floppy disk (FD) etc. or the various computer dependent programs that are installed in the storage device 70 by communication networks such as Internets, according to the indicated order of program that is loaded among this RAM62, CPU60 drives each resource carrying out expectant control and calculation is handled, thereby can realize the function separately of each mechanism as previously mentioned based on software.

Then, the flow chart of main reference Figure 20 illustrates and uses the flow process that as above constitutes the printing treatment of the printing equipment of realizing 100.

Also have, be used to print the printhead 200 of picture point as previously mentioned, in general can almost print the picture point of so-called multiple colors such as 4 looks and 6 looks simultaneously, but the picture point of establishing every kind of color in the example below for the ease of understanding explanation prints (black white image) by a kind of color (monochrome) printhead 200.

Shown in the flow chart of Figure 20, at first, after connecting power supply, after if this printing equipment 100 has been finished the predetermined initial actuating that is used for print processing, then move to initial step S100, with situation that not shown printing indication terminal such as computer is connected under, the step S102 below transferring to after described view data obtains the view data that mechanism 10 obtains many-valued (256 tonal gradation) is divided into a plurality of pixel areas with the view data that obtains by described view data division mechanism 12.Such as, the view data that obtains as previously mentioned be 720 * 720 pixels, the pixel area cut apart is 8 * 8 pixel sizes, then this view data is split to 225 pixel areas.

Then, if as mentioned above view data has been divided into a plurality of pixel areas, then move to next step S104, read in and constitute the stored predetermined pixel area picture points of table storing mechanism 16 by described picture point and constitute table 400, and continue to move to next step S106, read in the picture point configuration sequence table 500 that stores (preservation) by described picture point configuration sequence table storing mechanism 20 equally.

Then, after becoming the predetermined pixel area of handling object by next determining step S108 is selected, move to next step S110, add up to 14 pairs of calculation mechanism to become the concentration value that the pixel area of handling object adds up to all pixels in this pixel area by the pixel area concentration value, after calculating the total concentration value of this pixel area, move to next step S112.

In step S112, described picture point constitutes calculation mechanism 18 and constitutes the total concentration value of table 400 by this pixel area according to described predetermined pixel area picture point, calculates the picture point kind and the number thereof that are configured in this pixel area.Such as, if the total concentration value of this pixel area is " 9800 ", then because the mean intensity value shown in the arrow (※ 4) of Figure 12 is the most approaching for the total concentration value (9792) of " 153 " project, so, calculate picture point composition and the picture point kind and the number of dots of this pixel area according to this project.If according to the project shown in the arrow (※ 4) of Figure 12, the picture point constituent ratio that is set in this pixel area is a L size picture point " 2 ": M size picture point " 2 ": S size picture point " 1 ", the actual image point number is L size picture point " 21 ", M size picture point " 21 ", S size picture point " 10 ", and it adds up to the picture point number is that " 52 " are individual.

Then, if calculate the picture point kind and the number thereof of the corresponding pixel area of being scheduled to, then move to next step S114, described picture point collocation mechanism 22 is configured in these picture points in this pixel area according to the predetermined picture point configuration sequence table 500 that has read in abovementioned steps S106.

Also have, Figure 23 is that the expression concentration value adds up to " 6400 ", the picture point composition is a L size picture point " 0 ": M size picture point " 2 ": S size picture point " 1 ", the actual image point number is the figure of the picture point configuration example under L size picture point " 0 ", M size picture point " 30 ", S size picture point " 15 " situation, and 30 M size picture points, 15 S size picture points are the center, expand to the ellipticity of right tilted direction for the middle body with pixel area by, centralized configuration preferential from M size picture point.

Have again, Figure 24 is that the expression concentration value adds up to " 8000 ", the picture point composition is a L size picture point " 1 ": M size picture point " 1 ": S size picture point " 1 ", the actual image point number is the figure of the picture point configuration example under L size picture point " 16 ", M size picture point " 15 ", S size picture point " 16 " situation, and 16 L size picture points, 15 M size picture points, 16 S size picture points are the center, expand to the ellipticity of right tilted direction for the middle body with pixel area by, centralized configuration preferential from L size picture point.Promptly, in the example of Figure 24, the highest, the past more oval-shaped peripheral part of middle body concentration that is configured to pixel area is expanded the more and more shallow mode of its concentration.

In addition, Figure 25 is that the expression concentration value adds up to " 11840 ", the picture point composition is a L size picture point " 1 ": M size picture point " 1 ": S size picture point " 0 ", the actual image point number is the figure of the picture point configuration example under L size picture point " 28 ", M size picture point " 28 ", S size picture point " 0 " situation, and 28 L size picture points, same 28 M size picture points are the center, expand to the ellipticity of right tilted direction for the middle body with pixel area by, centralized configuration preferential from L size picture point.

More have, Figure 26 is that the expression concentration value adds up to " 14080 ", the picture point composition is a L size picture point " 2 ": M size picture point " 1 ": S size picture point " 1 ", the actual image point number is the figure of the picture point configuration example under L size picture point " 41 ", M size picture point " 21 ", S size picture point " 1 " situation, and 41 L size picture points, 21 M size picture points, 1 S size picture point are the center, expand to the ellipticity of right tilted direction for the middle body with pixel area by, centralized configuration preferential from L size picture point.

In addition, Figure 27 is that the expression concentration value adds up to " 15744 ", the picture point composition is a L size picture point " 1 ": M size picture point " 0 ": S size picture point " 0 ", the actual image point number is the figure of the picture point configuration example under L size picture point " 62 ", M size picture point " 0 ", S size picture point " 0 " situation, and 62 L size picture points are the center, expand to the ellipticity of right tilted direction for the middle body with pixel area by centralized configuration.

Below, return the flow process of Figure 20 again, after the picture point configuration process of having finished corresponding predetermined pixel area like this, return step S108 once more, judged whether the next one pixel area that is untreated, if (being) arranged, processing till then carrying out from step S110 to step S114 more repeatedly, to being judged as when no longer including the pixel area that is untreated (denying), move to step S116, generate mechanism's 24 synthetic these all pixel areas by described printed data, each pixel is made the printed data of having set predetermined image spot size after, move to last step S118 and use described printhead 20 to carry out by described printing mechanism 26 to print, finish all processing.

As, the printing equipment 100 of relevant present embodiment, be that view data with multi-grayscale is divided into the concentration aggregate value of trying to achieve each pixel area behind the pixel area, the picture point that is calculated in this pixel area by this concentration aggregate value constitutes, preferential from big picture point, as to concentrate on pixel area central part is configured, by like this, even having produced the picture point typewriting that is caused by the flight deflection phenomenon in this pixel area departs from, also can make this phenomenon not obvious, eliminate informal voucher line or dark this class fringe phenomena of striped, perhaps make it unshowy substantially.

Such as, as shown in figure 24, on the left side plays the 4th and goes when having produced the flight deflection phenomenon, directly carry out the concentration value of former pixel under the situation of picture point conversion, can produce fringe phenomena such as informal voucher line or dark striped near it and cause picture quality to suffer the significantly result of infringement, but by as shown in the figure like that at the middle body of this pixel area from the preferential centralized configuration picture point of big picture point, depart from even a little typewritings take place for what, the part that repeats between its picture point also can absorb this typewriting and depart from, thereby can avoid producing in its vicinity fringe phenomenas such as informal voucher line or dark striped, perhaps can suppress the generation of this situation significantly.

In addition, total concentration value in each pixel area after picture point disposes as described above, with original total concentration value about equally, make the input concentration value be easy to consistent with the output concentration value, thereby can avoid the decrease in image quality that causes because of change in concentration, particularly in the hierarchy chart picture, can also bring into play outstanding half tone reproduction.

More have, owing to can freely set pixel area size (littler) with dividing processing, so its pixel area can be no longer remarkable, can obtain the printed matter of high image quality.

Have again, in the present embodiment, be that as shown in figure 20 view data in step S100 is read in the pixel area dividing processing of carrying out view data after handling, but after this dividing processing also can be read in processing at the picture point formation table of step S104, perhaps after reading in processing, the picture point configuration sequence table of step S106 carries out.

Also have, when the picture point configuration that described picture point collocation mechanism 22 carries out, rotate to an angle, dispose if the picture point configuration of regulation is made as brokenly such as 90 ° * I (integer more than 0), owing to can get rid of the periodicity between the pixel area, thereby can be implemented in the raising of the picture quality in the same concentration part especially.

In addition, when synthetic each pixel area that generates by printed data that mechanism 24 carries out, also can each pixel area be rotated brokenly establish certain angle, be configured, also can obtain same effect identical therewith such as 90 ° * I (integer more than 0).

Have again, as color image data, print under multiple color in 1 pixel area, the situation such as the picture point of these 4 kinds of colors of CMYK, if as Figure 28～as shown in Figure 31, make each color screen angle with 15 ° stagger, 15 ° of cyans, yellow 30 °, 45 ° of black, 75 ° of carmetta, then can avoid the waviness phenomena when printing color image etc., thereby can obtain the chromatograp of high image quality.

In addition, distinguishing the technology of image spot size itself as described above in 1 printed matter, is existing known technology, particularly the technology that widely adopts in the printed matter of the print speed printing speed of pursuing realization height balance and press quality.That is, when trying to achieve high image quality by image spot size is diminished, what the miniaturization of image spot size brought is that mechanical precision is required high performance, or forms with the miniaturization picture point and need print more picture point when roughly covering (ベ ) image.Here, be that highly detail image partly makes image spot size diminish, roughly overlay image partly makes big this image spot size differentiation printing technique of image spot size change print print speed printing speed and image quality with the realization of height balance in utilization.

Method as the differentiation printing technique of realizing this image spot size, such as, in printhead 200, use under the mode of piezoelectric-actuator (piezo actuator), control the jetting amount of ink, can be easy to be achieved by changing the voltage that this piezoelectric-actuator is applied.

In addition, as the present invention and the common size of distinguishing the picture point of printing by printhead 200, as shown in Figure 7, in general " big picture point ", " middle picture point ", " little picture point ", " no picture point " these 4 kinds of patterns are arranged, but the kind of this image spot size, be not limited thereto, can also have 2 kinds of patterns at least except that " no picture point ", this pattern is The more the better.

Also have, the view data in the present embodiment obtains mechanism 10, view data division mechanism 12, the pixel area concentration value adds up to calculation mechanism 14, the pixel area picture point constitutes table 400, the pixel area picture point constitutes table storing mechanism 16, picture point constitutes calculation mechanism 18, picture point configuration sequence table 500, picture point configuration sequence table storing mechanism 20, picture point collocation mechanism 22, printed data generates mechanism 24, printing mechanism 26, printhead 200 is obtained mechanism to the view data in the printing equipment of mode 1 grade put down in writing in mode (summary of the invention) hurdle that is applied to solve problem respectively, the view data division mechanism, the pixel area concentration value adds up to calculation mechanism, the pixel area picture point constitutes table, the pixel area picture point constitutes the table storing mechanism, picture point constitutes calculation mechanism, picture point configuration sequence table, picture point configuration sequence table storing mechanism, the picture point collocation mechanism, printed data generates mechanism, printing mechanism, printhead.

Have again, the invention is characterized in, basically existing printhead 200 and printing mechanism 26 are not changed, and the total concentration value that is based in the pixel area comes the centralized configuration picture point, therefore do not need to prepare special facilities especially for printhead 200 and printing mechanism 26, and printhead 200 and the printing mechanism 26 (printer) that can directly apply flexibly the ink-jetting style of always both having deposited.

Therefore, if printhead 200 and printing mechanism 26 are separated from printing equipment 100 of the present invention, its function can only be achieved by general information treating apparatus (image processing apparatus) such as computers.

In addition, much less, the present invention is not only the flight deflection phenomenon, and is that vertical (normally) and the formation position of nozzle can be suitable under that caused and situation flight deflection phenomenon identical result when departing to some extent than regular position too to the direction of shooing out of ink.More have to cause by ink obstruction etc., can not from specific nozzle, shoot out under the unfavorable conditions such as ink and can be suitable for too.

Having, is unit are picture point formation table under the multiple situation in the kind of predetermined pixel area again, table that can also be shown in figure 32.

Table shown in Figure 32, it is total concentration value according to each pixel (pixel) in the pixel area, stipulate setting position (bit) ratio of each image spot size (L=is big, among the M=, S=is little) in this pixel area, and will stipulate particularly according to setting picture point number (actual image point number) and the number of dots total that in fact the picture point ratio dispose.

Such as, this table is that predetermined pixel area is the example under 4 * 4=16 pixel situation, under the concentration value average out to of each pixel (pixel) in pixel area " 0 (8 (bit); 256 the tonal gradations) " situation, represented that the total concentration value in its pixel area is " 0 ", its picture point ratio, the actual image point number, it all is " 0 " that number of dots adds up to, but under concentration value average out to " 30 " situation of each pixel (pixel) in the pixel area, represented that the total concentration value in this pixel area is " 480 ", the ratio that its setting picture point ratio is a L size picture point is " 0 ", the ratio of M size picture point is " 0 ", the ratio of S size picture point is " 1 ", and its actual image point number is that L size picture point and M size picture point are " 0 ", only S size picture point is " 6 ".Promptly, in the time of the concentration value average out to " 30 " of constituent parts pixel, only represented to show total concentration in this pixel area with 6 picture points.

In addition, similarly, under concentration value average out to " 70 " situation of each pixel (pixel) in the pixel area, represented total concentration value in this pixel area for " 1120 ", to set picture point ratio be that the ratio of L size picture point is " 1 " for the ratio of " 0 ", M size picture point for the ratio of " 1 ", S size picture point for it, its actual image point number is that L size picture point is that " 0 ", M size picture point are " 5 " for " 4 " S size picture point, but also has represented add up to " 9 " of this number of dots.Promptly, in the time of the concentration value average out to " 70 " of constituent parts pixel, represented to show total concentration in this pixel area with 9 picture points.

Like this, it becomes in the time of the concentration value average out to " 0,30,70,100,125,185,220,246 " of each pixel (pixel) in the pixel area, asks for total concentration value in this pixel area, it establishes the table that picture point ratio, actual image point number, number of dots add up to.

Also have,, use table described in Fig. 8 and the table described in Figure 32 to carry out the N value such as being by under 16 pixels and these two kinds of situations about constituting of 64 pixels when pixel area.

Below, with reference to Figure 33～Figure 35, the center of predetermined pixel area does not concentrate the embodiment of the situation of picture point to describe.

Picture point configuration sequence table storing mechanism is constructed as follows: store the picture point configuration sequence table that a kind of expression is configured in the configuration sequence of the picture point in the pixel area at least, and can read, utilize predetermined picture point configuration sequence table as required.

Picture point collocation mechanism 22 provides following function: according to the configuration sequence of picture point represented in the picture point configuration sequence table, will constitute picture point that calculation mechanism calculates by described picture point and constitute and offer pixel area.In the present embodiment, in the picture point configuration sequence table storing mechanism, store 2 kinds of picture point configuration sequence tables shown in Figure 33, Figure 34, can read these two kinds of tables each pixel area is distinguished use.

Promptly, each pixel of the corresponding pixel area of each component of picture point configuration sequence table, the configuration sequence of the numeral picture point of each component.Therefore, under the situation of Figure 33, configuration sequence 1～4 is placed in four angles, and last configuration sequence is 25 to be configured in the middle body of pixel area.Thereby, do not concentrate picture point at the center of pixel area, different with embodiment up to the present, be a kind of different table.In addition, the situation of Figure 34 is by having gathered a plurality of pixel areas shown in Figure 33, forms to concentrate picture point.Promptly, (B) is the table of arranging 4 (A).Above result as shown in figure 35, has represented that in the center and the excentral part of pixel of predetermined pixel area 4 places concentrate picture point.

In addition, printing equipment 100 of the present invention, be not limited to the ink-jet printer of line head, ink-jet printer be can also be applicable to repeatedly, if the ink-jet printer of line head, informal voucher literary composition or the dark unconspicuous basically high-quality printed matter of striped also can be obtained even flight deflection phenomenon etc. has taken place by type, in addition, if,, can realize than existing printing more at a high speed owing to can reduce round action frequency repeatedly by the ink-jet printer of type.Such as, in the time can realizing desired image quality, compare with K round situation of printing with 1 printing, printing time can be foreshortened to 1/K.

Figure 36 is expression by the ink-jet printer of line head and the figure of the mode of printing separately that carries out of the ink-jet printer by type repeatedly.

Shown in figure (A), if the width of the printing S of rectangle is the main scanning direction of view data, when length direction is the sub scanning direction of view data, ink-jet printer with line head, shown in figure (B), printhead 200 has the length of the wide amount of paper of this printing S, by fixing this printhead 200, making described printing S move this 1 time with respect to this printhead 200 on sub scanning direction to finish printing by (action).In addition, also can resemble fixing printing paper S so-called dull and stereotyped (flat bed) formula scanner, the limit is moved printhead 200 sides on its sub scanning direction or the limit makes both sides mobile in the opposite direction respectively, and print on the limit.Relative therewith, the ink-jet printer by type repeatedly, shown in figure (C), make more than the wide short printhead 200 of size of paper and be positioned on the direction that intersects vertically with main scanning direction, by the limit it repeatedly being come and gone on main scanning direction moves, the limit is moved printing S at every turn within a predetermined distance on sub scanning direction, carry out printing.Therefore, under the situation of the latter's the repeatedly ink-jet printer by type, compare with the ink-jet printer of the former line head and to have when more increasing this shortcoming of printing time, because it can make printhead 200 be positioned at any place institute repeatedly, thereby, can accomplish correspondence to a certain extent for alleviating of informal voucher line phenomenon particularly in the foregoing fringe phenomena.

Also have, in the present embodiment, be to be that the ink-jet printer that the picture point shape prints is that example is illustrated so that ink is shootd out, but the present invention also goes for using other the printing equipment that printing mechanism is arranged as the printhead of capable shape form, is called as bar code printing head printer, laser printer etc. such as heat transfer write printer or thermal printer etc.

Have again, among Fig. 3, each

nozzle module

50,52,54,56 of printhead 200 for each color setting, it is the form that on the length direction of its printhead 200, becomes continuous linearity nozzle N, but also can constitute such as shown in figure 37, with these each
