Thereby printer 1A forms image by the injection ink droplets such as nozzle 35a from shower nozzle 3 at print media, and wherein said shower nozzle 3 is fixed in position, and transmits print media simultaneously.In this example, with supposition from the ink droplet of nozzle 35c ejection because some factor and can follow inclined trajectory (tendency nozzle 35d) with respect to print media.

For example, shown in Fig. 1 (b), when nozzle 35a-35e sprays the size of ink droplet with the point shown in (2) that form Fig. 4 (a), form space D 2 in the ranks greater than preset space length P at the row of a B and some C.Therefore, a B and C produced the gap in the ranks, it is as occurring along the striped S of the direction of transfer H of print media.

Therefore, shown in Fig. 4 (b) of first embodiment, PC1 indication printer 1A is from nozzle 35c ejection ink droplet, formation has the point of the surface area bigger than the area of appointment in print data, and, form point with surface area littler than the area of appointment in print data from nozzle 35d injection ink droplet.

In other words, in first embodiment, when the ink droplet of adjacent nozzle 35d and 35c jet impact such as upper/lower positions, wherein said position is the position that has formed greater than spacings preset space length, between consecutive points, PC1 indication printer 1A increases the spot size corresponding to nozzle 35c, and also indicate the size that reduces corresponding to the point of nozzle 35d, its major part is covered by the point corresponding to nozzle 35c.In other words, two nozzle 35b on the either side that is arranged in nozzle 35c and 35d, nozzle 35d has produced such point, and this point has to the more short spacing of the point that is formed by nozzle 35c.Therefore, nozzle 35d is configured to spray ink droplet to form its size ratio corresponding to the littler point of the preliminary dimension of print data.

For forming above-mentioned point, the level point table 47a shown in Fig. 4 (c) has stored nozzle location number and corresponding level point value.Nozzle location number is assigned to respective nozzles 35a-35e.When the ink droplet from each nozzle 35a-35e ejection impacted print media, level point represented to form the instruction of the point of preliminary dimension.

Particularly, level point table 47a has stored nozzle location number " 1 " and the level point " 0 " that is used for nozzle 35a, the nozzle location number " 2 " and the level point " 0 " that are used for nozzle 35b, the nozzle location number " 3 " and the level point "+2 " that are used for nozzle 35c, be used for nozzle location number " 4 " and the level point " 1 " of nozzle 35d, and the nozzle location number " 5 " and the level point " 0 " that are used for nozzle 35e.PC1 outputs to printer 1A with instruction, is used for based on level point table 47a, sprays ink droplet from each of nozzle towards print media.

For example, when instruction being outputed to printer 1A when being used for forming point shown in (2) of Fig. 4 (a) by nozzle 35a-35e based on print data, PC1 output is configured to each the instruction corresponding to print data of nozzle 35a, the 35b of level point " 0 " and 35e based on level point table 47a.Therefore, the point that is formed by these nozzles on print media has the size shown in (2) of Fig. 4 (a).

Yet, to being arranged to the nozzle 35c of level point "+2 ", PC1 outputs to the point of printer 1A with the size shown in (4) that form Fig. 4 (a) with instruction, and its size is greater than the size corresponding to two level of size (size of the point shown in Fig. 4 (a) (2)) of the point of print data.Therefore, by nozzle 35c, the point that forms on print media has the size shown in (4) of Fig. 4 (a).

In addition, to being arranged to the nozzle 35d of level point " 1 ", PC1 is to printer 1A output order, is used to form the point of the size shown in (1) of Fig. 4 (a), and its size is less than the size corresponding to 1 level of spot size (spot sizes shown in Fig. 4 (a) (2)) of print data.Therefore, by nozzle 35d, the point that forms on print media has the size shown in (1) of Fig. 4 (a).

More particularly, so that head driver 25 is applied to shower nozzle 3 with voltage, wherein, level point " 0 " is a datum to PC1 based on the level point output order.The 20V voltage of instruction expression driving element, this voltage is used for nozzle 35a that is configured to datum " 0 " etc. is driven, represents the 30V voltage of driving element, this voltage is used for the nozzle 35c that is configured to level point "+2 " is driven, and the 15V voltage of expression driving element, it is used for the nozzle 35d that is configured to " 1 " is driven.

For example, in response, the driving element that applies 20V voltage sprays the ink droplet of 10pl from nozzle 35a, 35b and 35d, and the driving element that applies 30V voltage sprays the ink droplet of 15pl from nozzle 35c, and the driving element that applies the voltage of 15V sprays the ink droplet of 7.5pl from nozzle 35d.In other words, the ink droplet that sprays from nozzle 35a-35e is and the proportional basically amount of the voltage that is applied to driving element.

Therefore, the ink droplet that sprays from nozzle 35a, 35b and 35e forms the point of size of (2) expression of Fig. 4 (a) at print media, form the point of the size of representing with Fig. 4 (a) (4) from the ink droplet of nozzle 35c injection, it is than big two level of spot size of (2) expression of Fig. 4 (a), and the point that forms the size shown in (1) of Fig. 4 (a) from the ink droplet that nozzle 35d sprays, it is than little 1 level of the point shown in Fig. 4 (a) (2).

In above-mentioned first embodiment, the nozzle 35c among control adjacent nozzle 35b and the 35c is so that formation is more a little bigger, and the injection ink droplet of wherein said nozzle 35b and 35c has formed the adjacent point of its spacing greater than preset space length.The row of the point C that is obtained has reduced the gap that forms between by the row corresponding to the some C that ink droplet produced of print data and D, thereby has formed high quality graphic.

Yet when the size that increases corresponding to the point of nozzle 35c, the degree that these points cover corresponding to the point of nozzle 35d has also increased.Because the density in this area of coverage is distinguished greater than other, therefore since density unevenness spare and make image quality decrease.

Yet, by reducing size, even, also can reduce corresponding to the lap between the point of nozzle 35c and nozzle 35d when increase during corresponding to the size of nozzle 35c corresponding to the point of nozzle 35d.This method can prevent image quality decrease.

In addition, according to the degree of the China ink that sprays from nozzle 35c, to nozzle 35c set-point level "+2 " near nozzle 35d.In other words, the size in the gap that produces between the row based on some C that generates by ink droplet and D, set-point level corresponding to print data.By reading density, thereby can detect this gap size with CCD line scanning etc.

Example in the above preferred embodiment has been described such situation, has promptly formed point corresponding to nozzle 35b and 35c with space D 2.Yet, if with less than space D 2, but formed point corresponding to these nozzles greater than the spacing of spacing P, so apparent, because the gap is littler, therefore can make the level point that is provided with for nozzle 35c be reduced to "+1 " from "+2 ".In this case, the point that is formed by the ink droplet from nozzle 35c ejection is the size shown in Fig. 4 (a) (3), and it is less than the size of the point shown in Fig. 4 (a) (4).

In this way, thus can prevent the irregular density level that causes by the excessive covering between consecutive points simultaneously by according to the gap between the size filling point of clearence degree set-point.

In addition, level point table 47a is stored in rewrites on the hard disk 47 so that to each nozzle arrangement setting value.Therefore, if owing to some factor except that the problem of nozzle 35c makes nozzle 35a spray ink droplet on the direction away from nozzle 35b, for example, then by also being reduced corresponding to the some A of the ink droplet of print data and the gap that in the ranks produces of B.In this case, for example, the level point that is used for nozzle 35a changes over "+1 " from " 0 ", so that increase the size of the point that is formed by nozzle 35a.This variation makes the size of the point that is generated by nozzle 35a increase by 1 level, reducing the gap that forms of an A and B in the ranks, thereby keeps high image quality on long period.

Then, will describe control procedure, carry out control procedure by PC1 with said structure with reference to figure 5 according to second embodiment.Each size of point (1)-(4) that the ink droplet that Fig. 5 (a) expression is sprayed as the nozzle 35a-35d from printer 1A forms when impacting print media.Fig. 5 (b) show nozzle 35a-35e and the point that forms by the ink droplet of these nozzle ejection between relation.Fig. 5 (c) expression level point table 47a.

Second embodiment, with the same at first embodiment described in Fig. 4, supposed such situation, promptly make the nozzle 35c of nozzle 35a-35e spraying ink droplet (towards nozzle 35d) for some reason, produced the gap in the ranks at some C that forms by ink droplet and B corresponding to print data with respect to the incline direction of print media.

Therefore, in a second embodiment, PC1 indication printer 1A sprays ink droplet from nozzle 35b, forms the point of its surface area greater than the surface area of appointment in print data, and, form the point of its surface area less than the surface area of appointment in print data from nozzle 35a injection ink droplet.

In other words, in a second embodiment, when adjacent nozzle 35b and 35c have sprayed the ink droplet that impacts as upper/lower positions, described position has formed the spacing between consecutive points of being positioned at greater than preset space length, PC1 indication printer 1A increases the spot size corresponding to nozzle 35b, and also reduce spot size corresponding to nozzle 35a, and described nozzle 35a is arranged in nozzle 35a on the two sides of nozzle 35b and the nearest nozzle of 35c, and its major part is covered by the point of nozzle 35b.In other words, two nozzle 35a on the either side that is arranged in nozzle 35b and 35c, nozzle 35a produce and have than the point that is formed by the nozzle 35b point of short spacing more.Therefore, nozzle 35a is configured to spray ink droplet to form the point of ratio corresponding to the preliminary dimension smaller szie of print data.

Therefore, shown in Fig. 5 (c), level point table 47a among second embodiment has stored nozzle location number " 1 " and the level point " 1 " that is used for nozzle 35a, the nozzle location number " 2 " and the level point "+2 " that are used for nozzle 35b, the nozzle location number " 3 " and the level point " 0 " that are used for nozzle 35c, be used for nozzle location number " 4 " and the level point " 0 " of nozzle 35d, and the nozzle location number " 5 " and the level point " 0 " that are used for nozzle 35e.

For example, when being used for forming the instruction of the point shown in (2) of Fig. 5 (a) by nozzle 35a-35e based on print data to printer 1A output, PC1 is to each output of the nozzle 35c, the 35d that are configured to level point " 0 " based on level point table 47a and 35e instruction corresponding to this print data.Therefore, on print media, the point that is formed by these nozzles has the size shown in (2) of Fig. 5 (a).

Yet, to being arranged to the nozzle 35b of level point "+2 ", the instruction that PC1 will form the point of the size shown in (4) of Fig. 5 (a) outputs to printer 1A, and this size is than big 2 level of size (spot sizes shown in Fig. 5 (a) (2)) corresponding to the point of this print data.Therefore, the point that forms on print media by nozzle 35b has the size shown in (4) of Fig. 5 (a).

In addition, to being arranged to the nozzle 35a of level point " 1 ", the instruction that PC1 will form the point of the size shown in (1) of Fig. 5 (a) outputs to printer 1A, and this size is than little 1 level of size (spot sizes shown in Fig. 5 (a) (2)) corresponding to the point of this print data.Therefore, the point that forms on print media by nozzle 35a has the size shown in (1) of Fig. 5 (a).

By increasing corresponding to nozzle 35b, rather than the spot size of nozzle 35c, described in second embodiment, the row of the point B that is obtained can reduce the gap that forms at some B that is formed by the ink droplet corresponding to print data and C in the ranks, as in first embodiment, thereby make the gap not remarkable, and form high quality graphic.

Can also reduce corresponding to the point of nozzle 35b with corresponding to the overlapping area between the point of nozzle 35a by reducing size,, thereby prevent image quality decrease as in first embodiment corresponding to the point of nozzle 35a.

Then, will describe the control procedure according to the 3rd embodiment with reference to figure 6, this control procedure is carried out by the PC1 with said structure.The various sizes of point (1)-(4) that the ink droplet that Fig. 6 (a) expression is sprayed as the nozzle 35a-35d from printer 1A forms when impacting print media.Fig. 6 (b) show nozzle 35a-35e and the point that forms by the ink droplet of these nozzle ejection between relation.Fig. 6 (c) expression level point table 47a.

The 3rd embodiment, identical with first embodiment with second embodiment, supposed such situation, promptly, make the nozzle 35c of nozzle 35a-35e spraying ink droplet (towards nozzle 35d) for some reason, produced the gap in the ranks at some C that forms by ink droplet and B corresponding to print data with respect to the incline direction of print media.

Therefore, in the 3rd embodiment, PC1 indication printer 1A sprays ink droplet from nozzle 35b and 35c, has formed the point of its surface area greater than the surface area of appointment in print data, and, form the point of its surface area less than the surface area of appointment in print data from nozzle 35a and 35d injection ink droplet.

In other words, in the 3rd embodiment, when the ink droplet of adjacent nozzle 35b and 35c jet impact such as upper/lower positions, described position has formed the spacing greater than preset space length between consecutive points, PC1 indication printer 1A increases the spot size corresponding to nozzle 35b and 35c, and reduce corresponding to nozzle 35a on the both sides that are positioned at nozzle 35b and 35c and the spot size of 35d, described nozzle 35b and 35c major part are covered by the point corresponding to nozzle 35b and 35c.

Therefore, shown in Fig. 6 (c), level point table 47a among the 3rd embodiment has stored nozzle location number " 1 " and the level point " 1 " that is used for nozzle 35a, the nozzle location number " 2 " and the level point "+1 " that are used for nozzle 35b, the nozzle location number " 3 " and the level point "+1 " that are used for nozzle 35c, be used for nozzle location number " 4 " and the level point " 1 " of nozzle 35d, and the nozzle location number " 5 " and the level point " 0 " that are used for nozzle 35e.

For example, when to printer 1A output order when being used for forming point shown in (2) of Fig. 6 (a) by nozzle 35a-35e based on print data, PC1 is to the nozzle 35e output that is configured to level point " 0 " based on the level point table 47a instruction corresponding to this print data.Therefore, on print media, the point that is formed by this nozzle has the size shown in (2) of Fig. 6 (a).

Yet, to being arranged to the nozzle 35b and the 35c of level point "+1 ", PC1 is to printer 1A output order, and with the point of the size shown in (3) that form Fig. 6 (a), this size ratio is corresponding to big 1 level of size (spot sizes shown in Fig. 6 (a) (2)) of the point of this print data.Therefore, by nozzle 35b and 35c, the point that forms on print media has the size shown in (3) of Fig. 6 (a).

In addition, to being arranged to the nozzle 35a and the 35d of level point " 1 ", PC1 is to printer 1A output order, and with the point of the size shown in (1) that forms Fig. 6 (a), this size ratio is corresponding to little 1 level of size (spot sizes shown in Fig. 6 (a) (2)) of the point of this print data.Therefore, by nozzle 35a and 35d, the point that forms on print media has the size shown in (1) of Fig. 6 (a).

As mentioned above, in the 3rd embodiment, replace to increase one spot size, as described in first and second embodiment corresponding to nozzle 35b and nozzle 35c, can utilize two row of a B and C to reduce the gap that these produce in the ranks, thereby increase spot size corresponding to nozzle 35b and 35c.By making the gap not remarkable in this way, can form high quality graphic.

In addition, by reducing size corresponding to the point of nozzle 35a and 35d, overlay capacity between overlay capacity between the point that can reduce to be produced by nozzle 35a and 35b and the point that reduces to be produced by nozzle 35c and 35d described at first and second embodiment, thereby prevents image quality decrease.

In addition, different corresponding to the method for first and second embodiment of one the spot size of nozzle 35b and 35c with increase, the method for the 3rd embodiment has increased the size corresponding to the point of nozzle 35b and 35c simultaneously.In this case, owing to can utilize two points to reduce the gap that produces by ink droplet simultaneously corresponding to print data, the degree that every bit is increased is littler than the degree in first and second embodiment, thereby the granularity of inhibition point further improves picture quality.

Then, will describe the control procedure according to the 4th embodiment with reference to figure 7, this control procedure is carried out by the PC1 with said structure.The various sizes of point (1)-(4) that the ink droplet that Fig. 7 (a) expression is sprayed as the nozzle 35a-35d from printer 1A forms when impacting print media.Fig. 7 (b) show nozzle 35a-35e and the point that forms by ink droplet from these nozzle ejection between relation.Fig. 7 (c) expression level point table 47a.

In the 4th embodiment, owing to some factor causes following inclined trajectory (towards nozzle 35d) with respect to print media from the ink droplet that the nozzle 35c of nozzle 35a-35e sprays.In addition, the ink droplet that causes spraying from nozzle 35b owing to some factor is along the inclined trajectory (towards nozzle 35a) with respect to print media.Therefore, the ink droplet that sprays according to print data in the gap that in the ranks produces of a B and C greater than in the gap described in first to the 3rd embodiment.

In this case, as described in first or second embodiment, can reduce the gap that produces of some B and C in the ranks by increasing size corresponding to the point of nozzle 35b and 35c.

Yet, when attempting described in the 4th embodiment, must increasing size a little significantly when increasing only one the size of point corresponding to nozzle 35b and 35c and reduce in the ranks the big gap of a B and C.In this case, big naming a person for a particular job makes the image graininess remarkable, therefore, as described in the 3rd embodiment, preferably increases the size corresponding to the point of two nozzle 35b and 35c in the 4th embodiment.

Particularly, as described in the 3rd embodiment, PC1 indication printer 1A among the 4th embodiment sprays ink droplet from nozzle 35b and 35c, it has formed the point of its size greater than the size of appointment in print data, and from nozzle 35a and 35d injection ink droplet, it has formed its size less than the point by the size shown in the print data.

Wherein, by spraying the ink droplet corresponding to print data, in the 4th embodiment, the gap that forms between a B and C is greater than the gap described in the 3rd embodiment.Therefore, in the 4th embodiment, apparently, the size of the point that the size of the formed point of ink droplet that sprays from nozzle 35b and 35c must form greater than the ink droplet that sprays from same nozzle among the 3rd embodiment.

Therefore, shown in Fig. 7 (c), level point table 47a among the 4th embodiment has stored nozzle location number " 1 " and the level point " 1 " that is used for nozzle 35a, the nozzle location number " 2 " and the level point "+2 " that are used for nozzle 35b, the nozzle location number " 3 " and the level point "+2 " that are used for nozzle 35c, be used for nozzle location number " 4 " and the level point " 1 " of nozzle 35d, and the nozzle location number " 5 " and the level point " 0 " that are used for nozzle 35e.

For example, when to printer 1A output order when being used for forming point shown in (2) of Fig. 7 (a) by nozzle 35a-35e based on print data, PC1 is to the nozzle 35e output that is configured to level point " 0 " based on the level point table 47a instruction corresponding to this print data.Therefore, on print media, the point that is formed by this nozzle has the size shown in (2) of Fig. 7 (a).

Yet, to being arranged to the nozzle 35b and the 35c of level point "+2 ", PC1 is to printer 1A output order, and with the point of the size shown in (4) that form Fig. 7 (a), this size ratio is corresponding to big 3 level of size (spot sizes shown in Fig. 7 (a) (2)) of the point of this print data.Therefore, the point that forms on print media by nozzle 35b and 35c has the size shown in (4) of Fig. 7 (a).

In addition, to being arranged to the nozzle 35a and the 35d of level point " 1 ", PC1 is to printer 1A output order, and with the point of the size shown in (1) that forms Fig. 7 (a), this size ratio is corresponding to little 1 level of size (spot sizes shown in Fig. 7 (a) (2)) of the point of this print data.Therefore, the point that forms on print media by nozzle 35a and 35d has the size shown in (1) of Fig. 7 (a).

In the 4th embodiment, by increasing size, reduced the big gap that forms of some B and C in the ranks corresponding to the point of two nozzle 35b and 35c, suppressed granularity simultaneously.

Then, will describe the control procedure according to the 5th embodiment with reference to figure 8, this control procedure is carried out by the PC1 with said structure.The various sizes of point (1)-(4) that the ink droplet that Fig. 8 (a) expression is sprayed as the nozzle 35a-35d from printer 1A forms when impacting print media.Fig. 8 (b) show nozzle 35a-35e and the point that forms by ink droplet from these nozzle ejection between relation.Fig. 8 (c) expression level point table 47a.

In the 5th embodiment, the ink droplet that causes spraying from the nozzle 35c of nozzle 35a-35e owing to some factor is along the inclined trajectory (towards nozzle 35d) with respect to print media.In addition, the ink droplet that causes spraying from nozzle 35b owing to some factor is along the inclined trajectory (towards nozzle 35c) with respect to print media.Therefore, when spraying ink droplet, produced the gap in the ranks at an A and B based on print data.The space D in the ranks 2 of the 5th embodiment assumed position B and C equals injector spacing P and does not produce the gap in the ranks at a B and C.

Particularly, the 5th embodiment considers that the row of an A and B has the space D 1 greater than injector spacing P, when spraying ink droplet according to print data, an A and B produced the gap in the ranks, and the row of some C and D has the situation less than the space D 3 of injector spacing P.

In the 5th embodiment, PC1 indication printer 1A sprays ink droplet from nozzle 35b, forming the point of its size greater than the size of appointment in print data, and sprays ink droplet to form its size less than the point by the size shown in the print data from nozzle 35c.

Therefore, shown in Fig. 8 (c), level point table 47a among the 5th embodiment has stored nozzle location number " 1 " and the level point " 0; be used for nozzle location number " 2 " and the level point "+2 " of nozzle 35b; be used for nozzle location number " 3 " and the level point " 1 of nozzle 35c that is used for nozzle 35a, be used for nozzle location number " 4 " and the level point " 0 " of nozzle 35d, and the nozzle location number " 5 " and the level point " 0 " that are used for nozzle 35e.

For example, when to printer 1A output order when being used for forming point shown in (2) of Fig. 8 (a) by nozzle 35a-35e based on print data, PC1 is to the nozzle 35a, the 35d that are configured to level point " 0 " based on level point table 47a and the 35e output instruction corresponding to this print data.Therefore, on print media, the point that is formed by this nozzle has the size shown in (2) of Fig. 8 (a).

Yet, to being arranged to the nozzle 35b of level point "+2 ", the instruction that PC1 will form the point of the size shown in (4) of Fig. 8 (a) outputs to printer 1A, and this size is than big 2 level of size (spot sizes shown in Fig. 8 (a) (2)) corresponding to the point of this print data.Therefore, by nozzle 35b, the point that forms on print media has the size shown in (4) of Fig. 8 (a).

In addition, to being arranged to the nozzle 35c of level point " 1 ", the instruction that PC1 will form the point of the size shown in (1) of Fig. 8 (a) outputs to printer 1A, and this size is than little 1 level of size (spot sizes shown in Fig. 8 (a) (2)) corresponding to the point of this print data.Therefore, by nozzle 35c, the point that forms on print media has the size shown in (1) of Fig. 8 (a).

In above-mentioned the 5th embodiment,, can reduce by spraying corresponding to the ink droplet of print data in the gap that in the ranks produces of an A and B by increasing size corresponding to the point of nozzle 35b.Also can prevent image quality decrease by reducing size corresponding to the point of nozzle 35c.

Then, will the 6th embodiment that be used for by PC1 control printer 1A be described with reference to figure 9.Fig. 9 (a) be illustrated in the shower nozzle 3 the nozzle 35a that forms etc. and the point that forms from the ink droplet that nozzle 35a or the like sprays between relation.Fig. 9 (b) expression is when cause having identical relation when the deviation of nozzle 35d is impacted print media from the ink droplet of nozzle 35c injection owing to some factor.

Although usually instruction is outputed to printer 1A so as to be formed on four lines and five row in the point arranged, shown in Fig. 1 (a), but the PC1 among the 6th embodiment outputs to printer 1A with instruction, with at the row of the direction H that is used for transmitting print media (being called sub-scanning direction H hereinafter) and some A, C and the E row of offset point B and D relatively.In other words, PC1 instruction is outputed to printer 1A in case on sub-scanning direction H every a line skew one row.

Therefore, as described in reference to figure 1, row as fruit dot C do not impact print media in the desired locations shown in Fig. 9 (a), but cause for some reason having when the deviation of nozzle 35 is impacted, described reason has caused having towards the deviation of nozzle 35d from the ink droplet that nozzle 35c sprays, and then puts the spacing between the row of B and C, although greater than preset space length, but can not produce the same big gap between the row with the some B of Fig. 1 (b) and C, thereby prevent image quality decrease.

In this example, PC1 outputs to printer 1A with instruction, is used at sub-scanning direction H, makes half (1/2*D) of the space D of the point that the line skew of a B and C aligns in sub-scanning direction H greatly.Therefore, this arranges the gap between the row that reduce some B and C the most effective, makes towards the deviation of the row of the some C of the row of a D bigger.

Then, will the detailed method of the control of the point that forms as shown in Figure 9 be described with reference to Figure 10.Figure 10 (a) expression is arranged based on the pixel with four lines and five row of original print data.The transition status of the pixel layout among Figure 10 (b) and 10 (c) expression Figure 10 (a).Figure 10 (d) is illustrated in the pixel layout of the Figure 10 (c) that has represented with different colours, to the value of each pixel setting.

Usually, PC1 outputs to printer 1A with instruction so that form the point of each pixel based on the pixel layout of the original print data shown in Figure 10 (a), and printer 1A will spray ink droplet according to the instruction that receives from PC1.This method forms the point shown in Fig. 1 (a).

Yet in the 6th embodiment, pixel layout conversion program 45b converts the pixel layout shown in Figure 10 (a) to shown in Figure 10 (b) layout.More particularly, pixel layout conversion program 45b changes pixel layout, so that make the second and the 4th pixel column be offset the space D among the sub-scanning direction H half (1/2*D) on sub-scanning direction H.

Then, PC1 according to the conversion pixel layout shown in Figure 10 (b) to printer 1A output order to be used to form the point of each pixel.Printer 1A sprays ink droplet based on these instructions.In this way, can form point at the impact position place shown in Fig. 9 (a).

Act on the print data that is printed on the Line Chart picture that extends on the main scanning direction if the pixel layout shown in Figure 10 (a) seen, wherein said main scanning direction is perpendicular to sub-scanning direction H, and the pixel layout shown in Figure 10 (b) can be counted as being used to form the print data of the interlaced image that extends on main scanning direction so.

In other words, when by pixel layout conversion program 45b, when the original print data that will be used for the pixel layout shown in Figure 10 (a) converts layout shown in Figure 10 (b) to, in the image that forms according to this conversion pixel layout distortion has appearred.

Therefore, in the 6th embodiment, PC1 outputs to printer 1A with instruction, and on the rightabout as the offset direction of each offset column, the extra ink droplet that sprays a pixel value is to prevent image fault.Therefore, pixel layout conversion program 45b converts the pixel layout shown in Figure 10 (a) to shown in the layout rather than 10 (b) shown in Figure 10 (c) layout.Particularly, new pixel " 0-2 " and " 0-4 " have been added in the row end on the pixel layout conversion program 45b direction in the second and the 4th row, opposite with the offset direction, and the wherein said second and the 4th row are the pixel columns that are offset on sub-scanning direction H.

In addition, PC1 exports to printer 1A with instruction, to reduce the density of point, described end corresponding to the row that are offset in sub-scanning direction H from the density according to print data.Therefore, the pixel value allocator 45c pixel value that will be positioned at pixel " 0-2 " on the two ends of the second and the 4th pixel column that sub-scanning direction H goes up skew and " 4-2 " and pixel " 0-4 " and " 4-4 " is arranged to be lower than the pixel value corresponding to print data.

Pixel value is provided for each pixel and the definition density corresponding to the point of this pixel.For example, pixel value can be by from 0 to 255 value representation, wherein, concerning the pixel that is set to the value between 0 and 84, eject droplets of ink, and concerning the pixel that is set to the value between 85 and 169, spray medium ink droplet, and concerning the pixel that is set to the value between 169 and 255, spray big ink droplet.

The ink droplet of bigger size has formed black point.In addition, not only can be by the size of ink droplet, and can be by using the low-density China ink with the color except that pinkish red, yellow, green grass or young crops and black, thereby can be adjusted at the density of the point that forms on the print media.

For example, can be with each the pixel value of being arranged to 250 of the initial print data shown in Figure 10 (a) with as original pixel values.In this case, based on the pixel value of each pixel, printer 1A sprays big ink droplet and forms a little bigger of each pixel.

Yet, in the 6th embodiment, based on pixel layout conversion program 45b, PC1 at first converts the pixel layout shown in Figure 10 (a) to shown in Figure 10 (c) layout, then, based on pixel value allocator 45c, the part (pixel value 125) of the original pixel values 250 of pixel " 1-2 " is distributed to pixel " 0-2 " in second pixel column, the pixel value of pixel " 0-2 " is arranged to 125.Wherein, when adding for the first time, the pixel value of pixel " 0-2 " initially is arranged to 0 by pixel layout conversion program 45b.

Although after the part of pixel value is distributed to pixel " 0-2 ", pixel " 1-2 " becomes pixel value 125, but subsequently 125 value part of the original pixel values 250 of pixel " 2-2 " is distributed to pixel " 1-2 ", thereby make the value of pixel " 1-2 " turn back to its initial value 250.

By each pixel that constitutes secondary series is repeated this process, the pixel in the secondary series " 0-2 " and " 4-2 " finally are configured to 125, and pixel " 1-2 " to " 3-2 " is configured to their initial value 250.

Also on each pixel that constitutes the 4th row, carry out identical process, so that pixel " 0-4 " and " 4-4 " value of being configured to 125 in the 4th row, and pixel " 1-4 " to " 3-4 " value of being configured to 250.The pixel value of forming the first, the 3rd and the 5th row remains on their original pixel values 250.

Pixel value allocator 45c is arranged to pixel value 125 with pixel " 0-2 " and " 4-2 " and pixel " 0-4 " and " 4-4 ", wherein said pixel is configured on the two ends of the second and the 4th row that are offset among the sub-scanning direction H, and described pixel value 125 is half corresponding to the value 250 of print data.In this way, PC1 can output to instruction printer 1A, is used for being arranged to corresponding to the density of the point of pixel " 0-2 " and " 4-2 " and pixel " 0-4 " and " 4-4 " less than the density corresponding to the point of other pixels.

Therefore, add new pixel " 0-2 " and " 0-4 " to shown in Figure 10 (a) pixel layout, and reduce density corresponding to the point of pixel " 0-2 " and " 4-2 " and pixel " 0-4 " and " 4-4 " from the density of appointment print data, this makes that the point of locating to form at pixel " 0-2 " and " 4-2 " and pixel " 0-4 " and " 4-4 " is not too obvious, and therefore, formed such as following mode and more approached linear image, described mode is when the pixel layout among Figure 10 (a) being converted simply to layout shown in Figure 10 (b) and output order with formation during corresponding to the point of the pixel layout of being changed.Therefore, this method can prevent the distortion of Line Chart picture.

Then, will the situation of the meticulousr Line Chart picture of the previous image of print over be described with reference to Figure 11.Figure 11 (a) expression is based on the pixel layout of original print data.The pixel layout of Figure 11 (a) after Figure 11 (b) expression conversion.Figure 11 (c) has represented pixel value, uses different colours for each pixel in the layout of Figure 11 (b) these pixel values are represented.

As mentioned above, before printer 1A output order is with the ink droplet of injection corresponding to each pixel in the layout shown in Figure 11 (a),, convert the layout among Figure 11 (a) to shown in Figure 11 (b) layout according to pixel layout conversion program 45b.

More particularly, in sub-scanning direction H, make pixel " 1-2 " and " 1-4 " skew, and add new pixel " 0-2 " and " 0-4 " on the direction opposite offset pixels side with the offset direction.

Pixel value allocator 45c is provided with the value of each pixel in the layout shown in Figure 11 (b) as follows.In this example, each pixel in the original print data shown in Figure 11 (a) is arranged to original pixel values 250, and pixel " 0-2 " and " 0-4 " that newly adds is arranged to pixel value 0.

Particularly, the partial pixel value 125 of the original pixel values 250 of the pixel " 1-2 " that will be offset in sub-scanning direction H is distributed to pixel " 0-2 ", so that new pixel " 0-2 " and pixel " 1-2 " are arranged to pixel value 125.Similarly, the partial pixel value of the original pixel values 250 of the pixel " 1-4 " that will be offset in sub-scanning direction H is distributed to pixel " 0-4 ", so that make new pixel " 0-4 " and pixel " 1-4 " be pixel value 125.The pixel value of pixel " 1-1 ", " 1-3 " and " 1-5 " still is 250.

By this process, pixel value allocator 45c will be located at the pixel " 0-2 " at two ends of the pixel column that is offset among the sub-scanning direction H and the value of " 1-2 " and pixel " 0-4 " and " 1-4 " is arranged to 125, and it is half of pixel value 250 of appointment in print data.By carrying out this operation, instruction can be outputed to printer 1A, be set to less than density to be used for density corresponding to the point of pixel " 0-2 " and " 1-2 " and pixel " 0-4 " and " 1-4 " corresponding to the point of other pixels.

Therefore, as above-mentioned in preceding example, even when based on the pixel layout shown in Figure 11 (a), be printed on the main scanning direction than the trickleer Line Chart of image shown in Figure 10 as the time, not too remarkable at the point of pixel " 0-2 " and " 1-2 " and pixel " 0-4 " and the formation of " 1-4 " place.By forming more approaching linear image, this method can prevent the distortion of Line Chart picture.

Then, will the said method that pixel value is set be described with reference to Figure 12 and 13.Figure 12 (a) expression pixel layout conversion program 45b has been applied to the pixel of being changed the state of XY coordinate system.Figure 12 (b) shows the partial enlarged view of the conversion pixel of the method that allotment ratio is set.

Shown in Figure 12 (a),, coordinate system has been assigned to the pixel layout that skew produces every row according to pixel layout conversion program 45b by in sub-scanning direction H.In this coordinate system, the pixel that goes up most in the left column is an initial point, and right is the x axle, and left is to being the y axle.

Wherein, the value representation of each pixel is that (x y), wherein, is arranged on X from 0 to Xmax scope, and Y is set to from 0 to Ymax scope L.

Shown in Figure 12 (b),, the distribution ratio R of pixel value is set based on the ratio of the length T on the side of the side-play amount S of offset pixels and each pixel.Because in a preferred embodiment, make pixel just in time be offset half of length of a side, therefore, distribution ratio is 1/2.

Figure 13 shows the flow chart of the step in the pixel value assigning process.CPU44 carries out this process based on pixel value allocator 45c.In the S1 of this process, and CPU44 initialization coordinate (X, Y).In S2, CPU44 determines whether X is even number.If X is that (S2: not), so at S9, CPU44 makes X increase progressively 1 to odd number.

Yet, if X is even number (S2: be), in S3, CPU44 dispensed amount M.By distribution ratio R be multiply by with+Y direction on the object pixel adjacent pixels pixel value L (X, Y+1), thereby dispensed amount M.Behind dispensed amount M, at S4, CPU44 calculate object pixel pixel value L (X, Y), the value L by sendout M being added to object pixel (X, Y) on, thereby calculate object pixel value L (X, Y).At S5, CPU44 makes on+Y direction (X, Y+1) the sendout M that successively decreases with the pixel value L of object pixel adjacent pixels.

After finishing the process of target pixel, at S6, CPU44 makes Y increase progressively 1 so that handle next object pixel.At S7, whether the Y value that CPU44 determines next object pixel bottom (Ymax-1).If (S7: be), so, in S8, CPU44 initialization Y (Y=0) is if not (S7: not), so, CPU44 repeats this process from S3.

At S9, CPU44 makes X increase progressively 1 so that repeat said process on the next column of pixel.At S10, CPU44 determines whether the new value of X has reached right-hand member (Xmax+1), if (S10: be), this process finishes.(S10: not), CPU44 repeats this process from S2 so if not.

Then, will describe the seventh embodiment of the present invention, wherein, the spacing of nozzle 35a-35e will be arranged to the spacing q littler than traditional spacing P with reference to Figure 14 (a).Relation between Figure 14 (a) expression nozzle 35a etc. and the point that forms by the ink droplet that sprays from nozzle 35a or the like.

In the 7th embodiment, by the spacing of nozzle 35a etc. is arranged to less than the traditional spacing among Fig. 1, use the injecting time in the sub-scanning direction identical simultaneously with the tradition timing among Fig. 1, can be on main scanning direction, to form a little than the littler spacing of point that in sub-scanning direction H, forms.This method produces the overlapping area than the consecutive points that form on the bigger main scanning direction of the overlapping area of the consecutive points that form in sub-scanning direction H.

Shown in Figure 14 (a), spray ink droplet even nozzle 35c has towards the deviation of nozzle 35d direction ground, make thus the row of a C be formed the row of points of proximity D more, but put B and C to be listed in the 7th embodiment still overlapping.Therefore, the 7th embodiment makes gap between the row of a B and C less than the spacing shown in Fig. 1 (b), makes the gap not too significantly so that form high quality graphic.

Yet, reduce spacing between nozzle in this way and make lap at the point on the main scanning direction greater than the lap on the sub-scanning direction.Therefore,, reduce the size of the initial print data on the main scanning direction with respect to sub-scanning direction H, thus the image fault of making.

Therefore, the PC1 among the 7th embodiment outputs to printer 1A with instruction, thus with based on the spacing of nozzle 35a or the like reduce on sub-scanning direction, form more point.By doing like this, the ratio of the picture size among main scanning direction and the sub-scanning direction H is near the ratio corresponding to the picture size of print data, thereby reduces the distortion of image.

For example, pixel layout in four lines shown in Figure 10 (a) and five row is used as initial print data, thereby pixel layout conversion program 45b increases by four extra pixel columns by the reduction based on the size that is produced by the spacing that reduces nozzle 35a etc., thereby convert this pixel layout to layout, and think each pixel injection ink droplet of changing in the pixel layout to printer 1A output order with four lines and eight row.This method makes size of images among main scanning direction and the sub-scanning direction H than near the size ratio of original print data, thereby has reduced image fault.

Then, will the control procedure according to the 8th embodiment that is carried out by PC1 be described with reference to Figure 14 (b).Relation between Figure 14 (b) expression nozzle 35a etc. and the point that forms by the ink droplet that sprays from nozzle 35a etc.

In the 8th embodiment, injector spacing is arranged to equal traditional spacing among Fig. 1, but with the injection timing of sub-scanning direction H be arranged to be shorter than among Fig. 1 tradition regularly.Therefore, the overlapping area of the point that forms in sub-scanning direction H is greater than the overlapping area of the point that forms on main scanning direction.

Shown in Figure 14 (b), even having towards the deviation of nozzle 35d direction ground, nozzle 35c sprays ink droplet, so that make the row of a C form the more row of points of proximity D, but it is still overlapping to put being listed among the 8th embodiment of B and C.Therefore, the 8th embodiment makes gap between the row of a B and C less than the spacing shown in Fig. 1 (b), makes the gap not too significantly so that form high quality graphic.

Yet, the overlapping area of the point that the overlapping area by reducing the injecting time among the sub-scanning direction H, make the point that forms on sub-scanning direction forms greater than main scanning direction.Therefore, reduce the size of the initial print data among the sub-scanning direction H, produce image fault.

Therefore, the PC1 among the 8th embodiment outputs to printer 1A with instruction, thereby forms more point based on the injecting time of the minimizing of sub-scanning direction H in sub-scanning direction H.By doing like this, the size of images ratio on sub-scanning direction H and the main scanning direction is near the ratio corresponding to print data, thus the distortion of reduction image.

For example, when the pixel layout in four lines shown in Figure 10 (a) and five row is used as initial print data, pixel layout conversion program 45b passes through to increase by two extra pixel columns based on the injecting time of the minimizing of sub-scanning direction H, thereby this layout is converted to the layout of six row and five row, and, spray ink droplet with each pixel in the conversion pixel layout to printer 1A output order.Therefore, make size of images among main scanning direction and the sub-scanning direction H than near the size ratio of original print data, thereby reduce image fault.

Then, will the control procedure according to the 9th embodiment that is carried out by PC1 be described with reference to Figure 15.The 9th embodiment is the combination of described the 6th embodiment of Fig. 9 and described the 7th embodiment of Figure 14 (a), is used to control printer 1A.

Relation between Figure 15 (a) expression nozzle 35a or the like and the point that forms by the ink droplet that sprays from nozzle 35a or the like.The situation that Figure 15 (b) expression is so promptly, thereby has when the deviation of nozzle 35d direction arrives (medium) from the ink droplet that nozzle 35c sprays when causing for some reason, forms the point shown in Figure 15 (a).

Particularly, in above-mentioned the 6th embodiment, the 9th embodiment makes half (1/2*D) of space D of the point of arranging every a line skew of point among the sub-scanning direction H in sub-scanning direction H.In addition, as described in the 7th embodiment of Figure 14 (a), the 9th embodiment is provided with than the littler spacing q of traditional spacing among Fig. 1, and the injecting time of sub-scanning direction H is set to identical with injecting time among Fig. 1, in addition, based on reducing of the spacing of nozzle 35a etc., to printer 1A output order on main scanning direction, to form more point.

Owing to by in conjunction with the above-mentioned the 6th and the 7th embodiment, can realize general control method, with the description of this method of omission.

Make nozzle 35c have for some reason and spray ink droplet towards the deviation ground of nozzle 35d, therefore, even the ink droplet that arrives shown in Figure 15 (a) when expectation has formed the row that have towards the some C of a deviation of D column direction, this control also can reduce the gap that produces between the row of a B and C more than the conventional method shown in Fig. 1 (b).

Then, will the control procedure according to the tenth embodiment that is carried out by PC1 be described with reference to Figure 16.Shown in Figure 16 (a), the tenth embodiment is the combination of described the 6th embodiment of Fig. 9 and described the 8th embodiment of Figure 14 (b), is used to control printer 1A.

Relation between Figure 16 (a) expression nozzle 35a etc. and the point that forms by the ink droplet that sprays from nozzle a etc.When cause having when the deviation of nozzle 35d direction arrives from the ink droplet that nozzle 35c sprays owing to some factor, Figure 16 (b) has represented the state according to the point of the design formation of Figure 16 (a).

Particularly, as described in second embodiment, the tenth embodiment makes half (1/2*D) of space D of the point of arranging every a line skew of point in sub-scanning direction H in sub-scanning direction H.In addition, as described in the 7th embodiment shown in Figure 14 (b), the tenth embodiment is arranged to injector spacing p identical with traditional spacing among Fig. 1, the injecting time of sub-scanning direction H is arranged to be shorter than traditional time among Fig. 1, and, instruction is outputed to printer 1A to form more point in sub-scanning direction H also based on the injecting time that reduces in sub-scanning direction H.Since by with the above-mentioned the 6th and the 8th embodiment combination, realize this control method, therefore, with the detailed description of this method of omission.

If spray the ink droplet that has towards the deviation of nozzle 35d direction owing to some factor makes nozzle 35c, thereby the row of the some C that shown in Figure 16 (b), forms be formed with shown in Figure 16 (a) towards a deviation of D column direction, then this control method can reduce the gap that produces between the row of a B and C more than the conventional method shown in Fig. 1 (b).

Then, will the control procedure according to the 11 embodiment that is carried out by PC1 be described with reference to Figure 17.Relation between Figure 17 (a) and 17 (b) expression nozzle 35a or the like and the point that forms by ink droplet from nozzle 35a or the like ejection.

Being offset of point on the control procedure antithetical phrase scanning direction H among above-mentioned the 6th embodiment every row, and can be on the incline direction with respect to print media, the nozzle of ink droplet is sprayed in compensation, even need not those nozzles are discerned.Yet the control procedure of the 11 embodiment is by at first discerning those nozzles, and then the nozzle that sprays ink droplet on the direction that tilts at print media is compensated.

For example, in the 11 embodiment, the CCD line scanner is used for reading the gap that produces between a little each row based on density contrast.When the spacing that these data are used for determining the consecutive points on the main scanning direction is greater than preset space length, and two nozzles that are used for being identified in this position formation point.

For example, spray ink droplet, so that put space D 2 between the row of B and C, so, in a preferred embodiment, nozzle 35b and 35c are identified as two nozzles greater than the spacing of other adjacent column if nozzle 35c has towards the deviation of nozzle 35d direction ground.

Then, control two nozzle 35b and 35c one, so that the point that skew is formed by the ink droplet from this nozzle ejection in sub-scanning direction H only.

Figure 17 (a) expression dot pattern when the row that in sub-scanning direction H, are offset corresponding to the some B of pixel layout conversion program 45b.Therefore, spray ink droplet towards the deviation of nozzle 35d direction ground so that when more the row ground of points of proximity D forms the row of putting C when nozzle 35c has, the method for present embodiment can reduce the gap that forms between the row of a B and C more than the conventional method shown in Fig. 1 (b).

The dot pattern that Figure 17 (b) expression forms when the row that have been offset in sub-scanning direction H corresponding to the some C of nozzle 35c.As in the method shown in Figure 17 (a), spray ink droplet towards the deviation of nozzle 35d direction ground so that when more the row ground of points of proximity D forms the row of putting C when nozzle 35c has, this method also is reduced in the gap that produces between the row of a B and C more than the conventional method shown in Fig. 1 (b).

By in this way, after at first the nozzle that sprays ink droplet along the inclined trajectory with respect to print media being discerned, carry out suitable control, the method of present embodiment can make the quantity of the point range that is offset among the sub-scanning direction H minimize, so that inhibition image fault, rather than as in the control procedure of the 6th embodiment, make a little every a line skew.

Above-mentioned the 11 embodiment has solved the situation of the ink droplet that has formed the row that arrive the deviation position place's point C on the main scanning direction.Yet, if print media is impacted in the position of departing from sub-scanning direction H, can be on main scanning direction the row of offset point.

Then, will the ink-jet printer 2A as ink jet recording device of the present invention be described with reference to Figure 18.Figure 18 is the block diagram of the general structure of the electronic circuit among the expression ink-jet printer 2A.

For example, can in range or on print media, make up a plurality of ink droplets, produce the bigger surface area of the point that forms by combined drop effectively with predetermined.In addition, replace can using printer with the thermal source that is used for each nozzle from the printer 1A of nozzle ink jet with driving element, wherein, according to the heat that produces by thermal source from each nozzle ink jet.In this case, by being controlled at the heat that produces in each thermal source, can control the size of the point that forms by each nozzle.

In addition,, that is, the gap between point is detected, also the equipment that is used for detecting these gaps can be included in printer 1A by separating the ccd scanner that provides with printer 1A although above preferred embodiment has solved such situation.Therefore, this structure does not require independent checkout equipment, has eliminated the pressure of the independent checkout equipment detector gap of necessary use.

In addition, above preferred embodiment has solved such situation, and promptly the track of ink droplet has departed from direction perpendicular to print media on the direction of nozzle alignment.Yet, if the track of ink droplet has departed from the direction of transfer of print media, can pass through the time of control, thereby reduce the gap that forms between point from the nozzle ejection ink droplet.

In addition, in above preferred embodiment, the level point of storing in level point table 47a is based on the parameter of level " 0 ", and how many level expression has be greater than or less than the size of formation with respect to the point of level " 0 ".Yet the parameter that is stored as level point is not limited to these values.For example, the magnitude of voltage that puts on each nozzle directly can be stored as level point.This structure has the effect that increases processing speed, because it needn't verification and the correlation of predefined parameter.

In addition, if the little gap of generation in the ranks at a D and E, for example, as in first embodiment of Fig. 4, when the size of the point that reduces to produce by nozzle 35d, the level point of nozzle 35e can be adjusted to "+1 " from " 0 ", so that nozzle 35e produces the point of its size greater than the size of appointment in print data.In this way, can use the row of some E to be reduced in the little gap that produces of a D and E in the ranks, so that form high quality graphic.

Although the above-mentioned the 9th and the 11 embodiment has solved in sub-scanning direction H every row and has been offset or the situation of the specify columns of offset point, but also can output order so that nozzle spray site in offset column, so that on the end of the row opposite, spray the extra ink droplet be used for a pixel, as described in the 6th embodiment with the offset direction.This has suppressed the distortion of image by adjusting pixel layout.
