Description

[0001]
[Industrial applications]
The present invention relates to a multicolor thermal / thermal transfer recording method in which images of a plurality of originals are recorded in multiple colors by using both thermal recording and thermal transfer recording, and an apparatus directly used for performing the method. is there.
[0002]
[Prior art]
A recording apparatus has been proposed in which thermal recording is performed on a thermal recording sheet using a heating head (thermal head), and thermal transfer recording is performed by superimposing a thermal transfer donor sheet (hereinafter referred to as an ink ribbon) on the thermal recording sheet ( JP-A-57-210872).
[0003]
In the proposed device, three primary colors of red, blue, and yellow and a colorless region are provided at regular intervals on an ink ribbon (referred to as a full-color system). Then, an area of any color of the ink ribbon is guided between the heating head and the heat-sensitive recording sheet for printing. That is, the red, blue, and yellow areas of the ink ribbon are selectively overlapped with the thermal recording sheet and heated by the heating head, so that the ink of the ink ribbon is thermally transferred to the thermal recording sheet. Also, the colorless area of the ink ribbon is superimposed on the heat-sensitive recording sheet and heated by a heating head so that the heat-sensitive sheet is colored.
[0004]
[Problems of the prior art]
However, in this method, the heat of the thermal transfer using the ink ribbon causes the thermal recording layer of the thermal recording sheet to simultaneously develop color. For this reason, there arises a problem that the color formation by thermal transfer and the color formation by heat sensitivity overlap and mix, and it becomes impossible to obtain a beautiful color formation.
[0005]
In particular, when a plurality of originals are printed out in a superimposed manner, a portion for thermal recording and a portion for thermal transfer recording in different originals may overlap. Also in this case, in the above-described conventional apparatus, the colors are superimposed and mixed.
[0006]
[Object of the invention]
The present invention has been made in view of such circumstances, and when printing a plurality of originals in a superimposed manner, it is possible to form a beautiful color without mixing the color formed by thermal recording and the color formed by thermal transfer recording.

[Outline of the device]
First, a procedure for performing multicoloring on a single document, which is a basic operation of the present embodiment, will be described with reference to FIGS. 1 to 12, and then, a procedure for superimposing and printing a plurality of documents which are objects of the present invention will be described. explain. First, the arrangement structure of each part of the image processing apparatus will be described with reference to FIGS. In FIG. 1, reference numeral 10 denotes a horizontally long housing, and the upper surface thereof is a lid 12 which can be opened and closed upward.
[0013]
A printer 14 is housed inside the housing 10 as shown in FIGS. The printer 14 has a paper roll 16 and a platen 18 arranged in parallel in a horizontal direction. The platen 18 is located on the front side of the paper roll 16, and the paper 20 drawn from the lower edge of the paper roll 16 is wrapped around the platen 18 and guided downward from the front edge of the platen 18. A pinch roller 19 presses the paper 20 against the platen 18.
[0014]
The paper 20 can be further discharged from below the front surface of the housing 10 by guide rollers 22 and 24. The platen 18 is driven by a belt by a feed motor 26 to feed the paper 20 in a feeding direction or a rewinding direction and position the paper 20.
[0015]
The printer 14 includes three print heads 28 (28a, 28b, 28c) that travel left and right along the front surface of the platen 18. The print head 28 is guided by a guide rod 30 and is sent left and right by a belt 34 wound around a carriage motor 32. The print head 28 is of a multicolor thermal / thermal transfer recording type described later, and moves at intervals D so as to divide the entire print width 3D (FIG. 4) of the paper 20 into three equal parts, and the right end of each movement range returns. Position (home position, HP).
[0016]
The paper 20 used for the printer 14 is a heat-sensitive recording sheet, and for example, a paper that thermally develops black on a white background is used. Each print head 28 is attached with an ink ribbon (thermal transfer donor sheet) of one or more colors different from the color of the heat-sensitive color of the paper 20 and one heating head. The structure will be described later. In FIG. 4, reference numeral 36 denotes a print area (recording area) by the print head 28.
[0017]
In FIG. 3, reference numeral 40 denotes a cutter which cuts the print paper 20 below the platen 18. That is, the fixed blade and the movable blade are opposed to each other with the paper 20 interposed therebetween, and when the movable blade is moved by the motor, the movable blade moves to the fixed blade side to cut the paper 20.
[0018]
Reference numeral 42 denotes a scanner, which is located near the center of the upper surface of the lid 12. As shown in FIG. 4, the scanner 42 transports the document from the right to the left with a document 46 interposed between the holding lid 44 placed on the lid 12 from above and the holding lid 44 and the lid 12 of the housing 10. A mechanism, a CCD line sensor 48 accommodated in the housing 10, and an optical system for guiding an image on a main scanning line orthogonal to the transport direction of the document 46 to the line sensor 48 are provided.
[0019]
As shown in FIG. 4, the transport mechanism is composed of four feed rollers 50 which feed the original 46 from right to left while sandwiching the original 46 from above and below, and the two rollers 50 on the housing 10 are rotationally driven by a motor (not shown). Is done. The optical system includes an appropriate number of mirrors 52 and lenses 54. Reference numeral 56 denotes a light source.
[0020]
Reference numeral 58 denotes a digitizer, which is provided on the upper surface of the lid 12 adjacent to the input side of the original 42 of the scanner 42, that is, adjacent to the right side. This digitizer 58 includes a coordinate detection tablet 60 and a stylus pen 62 as shown in FIG. The tablet 60 has a resistor that spreads over the entire surface, and detects coordinates from a change in resistance value when the tip of the stylus pen 62 presses the tablet 60. For example, the upper right corner of the tablet 60 is determined as a reference position, and the upper right corner of the document 46 is aligned with this reference position and fixed.
[0021]
Numeral 64 denotes a print operation panel for instructing print data, and numeral 66 denotes a coloring operation panel, which are mounted on the upper surface of the pressing lid 44 of the scanner 42. That is, as shown in FIG. 1, a coloring operation panel 66 is arranged on the back side of the upper surface of the holding plate 44, and a print operation panel 64 is arranged on the front side thereof. The operation of these operation panels 64 and 66 will be described later.
[0022]
The printer 14, the scanner 42, the digitizer 58, and the operation panels 64 and 66 are connected to the bus 70 via interfaces 68a to 68d (FIG. 7).
[0023]
The bus 70 is also connected to a CPU 72, a ROM 74, a RAM 76, and the like. The ROM 74 stores an operation program of the CPU 72 and various constants. The CPU 72 serves as a control device 78 (FIGS. 2 and 4) for performing various controls according to the operation program, and also serves as a control device of the printer 14. When operating this image processing apparatus, the control device 78 performs control according to the operation flowchart of FIG. 8, and controls each print head 28 according to FIG. 12 during printing.
[0024]
[Coloring edit operation]
Next, the operation of the coloring and editing process according to this embodiment will be described with reference to FIG. First, when past coloring data remains, the coloring data display LED 102 (FIG. 6) of the operation panel 66 is lit. If this LED 102 is lit, the all clear key 100 of the operation panel 66 is turned on. Press to erase this past coloring data. In the case where no coloring is performed, that is, when printing is performed in a single color (single color mode) (step 200), the document 46 may be set as it is on the scanner 42 (step 212) and printed.
[0025]
The printer 14 according to the present invention uses both thermal recording using a thermal recording sheet and thermal transfer recording using an ink ribbon. Therefore, the color designation key group 104 has a key group (1, 2, 3) for thermal transfer recording and a key group (4) for thermal paper density separately. Therefore, if the coloring of the thermal recording is performed, the appropriate density (A to D) in the key group (4) is selected, and if the coloring is performed by the thermal transfer, the appropriate density (A to E) of the key group (1 to 3) is selected. do it. The key groups (1, 2, 3) are, for example, red, green, and blue, respectively, and correspond to the colors of the ink ribbon set on the print head 28 described later.
[0026]
If multi-coloring is to be performed (step 200), the document 46 is set on the digitizer 58 (step 202). That is, the document 46 is placed on the tablet 60 with its front face up, and its upper right corner is aligned with the reference position (upper right corner) of the tablet 60. Next, the mode of the coloring method is selected to be either color conversion or background color (step 204). This mode selection is performed by the switching key 106. That is, each time the switch key 106 is pressed, the LED 108a indicating the color conversion mode and the LED 108b indicating the background color mode are alternately turned on, so that the selected mode can be known. The color conversion mode is to convert the color of the image (black portion of the original) whose coordinates are input as described below. The background color mode is used to input the color of the background (white portion of the document) of the area where the coordinates are input.
[0027]
Next, the coordinates of the area to be colored by the digitizer 58 are input (step 206). For example, when coloring an image (color conversion mode), an area including the image to be colored is specified. If this area is a square, this area is specified by specifying two points on its diagonal positions. This area may specify a polygonal area by connecting a number of points. In the case of background painting, an area is specified in the same manner.
[0028]
After inputting the coordinates in this manner, a color designation for coloring the area is performed using the key group 104 (step 208). By repeating the above operations of steps 204 to 208 until all coloring is completed, coloring and editing of all images and regions are performed (step 210), and the results are stored in the RAM 76 or the like. That is, data relating to coordinates and colors is stored. When the coloring and editing are completed (step 210), the printing operation starts.
[0029]
First, the document 46 is set on the scanner 42 (step 212), and print conditions are set on the operation panel 64 (step 214). That is, the output mode of standard output, photo output or reverse output is selected with the key 110, the document density is set with the key 112, and the print size is set with the key 114. If the user wants to check the print result made by these settings before the actual print, he presses the check print key 116 (step 216).
[0030]
Then, the scanner 42 starts operating to read the image of the original 46 and print out an image (for example, A7 size) smaller than the actual print (step 218). In this printing operation, the image being read is colored in parallel with the already input coloring data. That is, the printing is performed by the printer 14 while interlocking with the scanner 42.
[0031]
Looking at the result of the confirmation print output in such a small size, if there is further correction, the color editing is performed again on the corrected portion. To perform the actual print, the original 46 is set on the scanner 42 again (step 220), and the start / stop key 118 is pressed. Then, while the original document 46 is read by the scanner 42, the coloring process is simultaneously performed in parallel, and printed out (step 222). As described above, since the document 42 is read by the scanner 42 and output to the printer 14 in parallel, the capacity of the image memory can be reduced.
[0032]
[Printer]
Next, the printer 14 for performing multicolor heat-sensitive / thermal transfer recording will be described. In the printer 14, the thermal paper is used as the print paper 20, and the thermal transfer using the thermal transfer ink ribbon is also performed in an overlapping manner. Each of the three print heads 28 has one heat generating head 150 and three ribbon cases 152 (152a, 152b, 152c). The ink ribbons (thermal transfer recording donor sheets) 154 housed in the ribbon cases 152 are separately provided corresponding to the colors of the keys 1, 2, and 3 of the color designation key group 104 of the coloring operation panel 66. In the example, there are three lines of red, green and blue.
[0033]
The ribbon case 152 is movable with respect to the heating head 150 as shown in FIGS. FIG. 7A shows a state in which all the ribbons 154 have exited the gap between the heating head 150 and the paper 20. FIG. 7B shows a state in which the ribbon 154 of the ribbon case 152a is inserted between the heating head 150 and the paper 20. Similarly, the ribbon 154 of the ribbon cases 152b and 152c can selectively enter between the heating head 150 and the paper 20.
[0034]
The paper 20 made of thermal paper has a support 20A and a thermal recording layer 20B as shown in FIG. The heat-sensitive recording layer 20B contains a leuco dye and a color developer. The ink ribbon 154 has a support 154A and a thermal transfer layer 154B. The thermal transfer layer 154B contains a desensitizing substance that suppresses a color-forming reaction between the leuco dye and the developer of the thermal recording layer 20B, and one or both of a colored dye and a colored pigment.
[0035]
The leuco dye, the developer, the desensitizing substance, and the colored dye (pigment) used herein are described in detail in Japanese Patent Application No. 5-264997 filed by the same applicant. Absent.
[0036]
When the heating head 150 is brought into contact with the surface of the paper 20 on the side of the heat-sensitive recording layer 20B, a color is formed (heat-sensitive coloring) by the reaction between the leuco dye and the developer of the heat-sensitive recording layer 20B. In the case of this embodiment, the color is black. In FIG. 11A, reference numeral 156 indicates this colored portion. If the heating head 150 generates heat at a predetermined coordinate position, only the predetermined coordinate position can be colored black.
[0037]
When the ink ribbon 154 is placed on the heat-sensitive colored paper 20 and heated by the heating head 150, coloring by thermal transfer is performed as shown in FIG. That is, the desensitizing substance of the thermal transfer layer 154B of the ink ribbon 154 suppresses the coloring of the thermal recording layer 20B, while the colored dye (or pigment) contained in the thermal transfer layer 154B is transferred to the surface of the paper 20.
[0038]
Since the coloring of the heat-sensitive recording layer 20B is suppressed by the desensitizing substance, the coloring of the colored dye (pigment) does not mix with the coloring of the heat-sensitive recording layer 20B, and the color becomes vivid and clear. Reference numeral 156A in FIG. 11B indicates a portion where the coloring of the heat-sensitive recording layer 20B is suppressed by the desensitizing substance. Reference numeral 158 denotes a colored dye (pigment) portion of the transferred ink ribbon 154.
[0039]
[Printer operation]
In the present invention, thermal coloring and thermal transfer are performed using one heating head 150. That is, the three print heads 28 are placed at the respective home positions HP, and the heating head 150 is brought into contact with the paper 20 as shown in FIG. 11A to perform thermal recording (FIG. 12, step 300). FIG. 9A shows that the operation range of each print head 28 at this time is D. By one recording operation of the heating head 28, thermal recording of the width of the heating head 28 (width in the feeding direction of the paper 20, about 22 mm) is performed.
[0040]
The heating head 28 returns to the original home position HP (step 302), and then performs thermal transfer recording on the same print area 36 (see FIG. 4) of the paper 20. That is, first, the ribbon 154 of the first ribbon case 152a is inserted between the heating head 150 and the paper 20 (step 304), and heat is transferred at a predetermined coordinate position while the heating head 150 is moved (step 306). Then, the heating head 150 is returned to the original home position HP (step 308), and the same operation is repeated for the other two colors by changing to the ink ribbon 154 of a different color (steps 310 and 312). In FIG. 10B, A, C, H, and J indicate characters subjected to thermal recording, and B indicates a character obtained by thermal transfer recording.
[0041]
The above operation is repeated for the continuous print area 36 while intermittently feeding the paper 20 (steps 314 and 316). When the printing of all the areas 36 is completed, the paper 20 is fed by a predetermined amount and cut by the cutter 40.
[0042]
When thermal transfer is performed, colored dyes (pigments) and waxes contained in the thermal transfer layer 154B are transferred to the paper 20, so that after the thermal transfer recording, the heating head 150 is brought into direct contact with the paper 20 to perform thermal color development. Colored dyes (pigments) and waxes on the paper 20 adhere to the heating head 150. For this reason, beautiful print cannot be performed. Therefore, in the present invention, thermal recording is performed first, and then thermal transfer recording is performed. This makes it possible to perform multicolor printing with one heating head 150.
[0043]
[Overprint]
In the above description, the actual printing is performed after the coloring process is performed on one document and the confirmation print is performed as necessary. Next, a method and apparatus for printing a plurality of originals in a superimposed manner using this apparatus will be described. In this case, first, the overlay print selection key 103 (FIG. 6) of the coloring operation panel 66 is pressed.
[0044]
FIG. 13 is a conceptual diagram of overlap printing, and FIG. 14 is an operation flow chart showing an embodiment thereof. In this embodiment, the first original (first original) is subjected to thermal recording, and the second original (second original) or subsequent originals are recorded.Is thermal transferMake a record. For example, consider a case in which the characters shown in FIG. 13B are printed with the landscape image shown in FIG. 13A as a background and the output shown in FIG. 13C is obtained.
[0045]
In this embodiment, first, the background of (A) is colored and set to a single color (step 400 in FIG. 14), and the coloring information is stored in the RAM 76 (FIG. 7) or the like. The original (1) is set on the scanner 42 and its image is read (step 402), and the printer 14 prints out the image by thermal recording in synchronization with the image reading (step 404).
[0046]
When the thermal recording of the first document (1) is completed, the recording sheet 20 is returned to the original position (step 406), the next page key 103A of the coloring operation panel 66 is pressed, and the next second document (2) is pressed. Color setting is performed (step 408). This coloring settingIs thermal transferIncludes records. While reading the original (2) with the scanner 42 (step 410), the recording sheet 20 is read.Thermal transfer toRecording is performed (step 412).
[0047]
ManuscriptIf the thermal transfer recording portion of (2) overlaps the thermal recording portion of the original (1), the thermal recording of the original (1) or (2) disappears due to the action of the desensitizing substance contained in the ink ribbon. Therefore, the color of the thermal transfer appears vividly without mixing.
[0048]
When there are three or more originals, the steps 406 to 412 may be repeated for the third and subsequent originals. At this time, if the thermal transfer recording portions overlap, color mixing may occur. Therefore, it is desirable to set the coloring so that the portions do not overlap. It is conceivable that there are a plurality of thermal recording originals corresponding to the original (1). In this case, the recording sheet 20 is returned for each original (1), and the procedure of steps 400 to 404 can be repeated. What is necessary is just to repeat the procedure of steps 406 to 412.
[0049]
FIG. 15 is an operation flowchart of another embodiment. In this embodiment, the images of some originals and their coloring information are stored in the RAM 76 or the like, and the contents stored in the memory are combined in synchronization with the reading of the other originals. The printout is performed in an overlapping manner.
[0050]
That is, first, the overlapping print key 103 is pressed to set the color of the first original (1) for thermal recording (step 500). Images are read by the scanner 42 (step 502), and these are stored in the RAM 76 (step 504). Next, the document next page key 103A is pressed to set the second (2) color (step 506), and while reading by the scanner 42 (step 508), the contents stored in the memory are read out in synchronization with this reading to synthesize the image. This is performed by the computer, that is, the CPU 72 (step 510). Image synthesis is performed in synchronization with image reading by the scanner 42, and at the same time, thermal recording is performed on the printer 14 (step 512), followed by thermal transfer recording (step 514).
[0051]
FIG.The present inventionExample ofNot a reference example3 is an operation flowchart of FIG. In this embodiment, a plurality of scanners are synchronized, and a composite image is printed out while reading a plurality of images. That is, when there are two documents, a scanner 42A and an interface 68bA are provided in addition to the scanner 42 (FIG. 7). First, the original (1) is colored and set to a single color (step 600), and then the original (2) is colored (step 602). These coloring information are stored in memory.
[0052]
Next, the originals (1) and (2) are set on different scanners 42 and 42, respectively, and both scanners 42 and 42 are read in synchronization (step 604). Further, the two originals (1) and (2) are combined in synchronism with the reading (step 606) and output to the printer 14 simultaneously. At this time, thermal recording is performed first (step 608), and thermal transfer recording is performed thereafter (step 610).
[0053]
[Other embodiments of the printer]
Although the printer 14 used in the above description has been described as using the three-color ink ribbon 154 and one heating head, the printer 14 includes a heating head for thermal recording and one or more heating heads for thermal transfer recording. May be.
[0054]
In the above embodiments, the three-color ink ribbon 154 is used as the thermal transfer donor sheet. However, a single ink ribbon is provided with portions of different colors such as yellow, magenta, cyan, and black in order in a fixed length. (Full color system). The ink ribbon 154 used is not limited to three colors, but may be three or more colors, or two or less colors, for example, one color.
[0055]
If the support 20A of the paper 20 is colored in advance so that the heat-sensitive coloring and the heat transfer are different colors, the number of colors usable for printing can be further increased. Further, instead of integrating a plurality of ribbon cases into the printer head, the ribbon case 152 may be replaced at the home position of the print head (stocker system).
[0056]
The printer 14 of the above embodiment prints a part of the print area 36 of the recording sheet 20 in multi-color before printing the next print area 36. However, after recording the entire image to be printed out by thermal recording, the recording sheet 20 may be returned, and then the entire image may be subjected to thermal transfer recording. In this thermal transfer recording, the recording sheet 20 can be returned every time the color of the ink ribbon is changed, and the entire image can be recorded separately for each color. In this case, it is, of course, necessary to reset the originals (1) and (2) on the scanner each time recording is performed.
[0057]
【The invention's effect】
As described above, the invention of claim 1 includes a thermal transfer donor sheet containing a desensitizing substance and a colored dye or a colored pigment for suppressing a color development reaction between a leuco dye and a developer, and After performing thermal recording with a thermal recording sheet, another document is thermally transferred and recorded.Therefore, even when multiple documents are superimposed and printed in multiple colors, there is no color mixing between the thermal coloring portion and the thermal transfer coloring portion. , Vivid and beautiful multi-color printing becomes possible.
[0058]
hereToPrinting is performed in synchronization with scanning of the original, and the recording sheet is returned to the original for each original to be overlapped, and multiple images are overlaidFromSince the document must be set on the scanner a plurality of times, the operation is somewhat troublesome. However, the apparatus is not complicated, which is suitable for reducing the number of parts and reducing the cost.
[0059]
AlsoWhen recording three or more originals,Increase the memory capacity,The second and subsequent pages except the last oneStores the original image and its coloring information,lastIt is also possible to combine a plurality of originals while reading the originals with a scanner and print out the same at the same time.2). In this case, even if the thermal transfer recording portions overlap, it is possible to prevent color mixing between the thermal transfer recording portions by setting the priority.
[0060]
AlsoIn the case where portions to be subjected to thermal transfer recording overlap each other, by setting priorities, it is possible to prevent color mixing between thermal transfer recordings.
