The control H 21 provides a control signal to the printing medium moving unit 22 to cause the printing medium moving unit 22 to operate and the J I3 media 112. Move some areas to be printed to print five. Then, the control °α 21 further supplies a control signal to the carriage moving unit 23 to cause the carriage 12 to select a reciprocal movement in which the direction of the movement of the printing medium 112 is alternated. At this time, the controller 21 supplies a control signal to the inkjet head 25 having a plurality of (four) ink holes (nQzzles), so that the ink is printed on the printing medium 112 at the position to be printed in the printing area to reach 歹. The J p action and the above-mentioned action can print all the areas to be printed by the printing medium m. However, the conventional ink control method has a high resolution and high resolution of 12 眶 or more. When the printing speed is printed, the ink droplets of the next inkjet are immediately sprayed on the same position of the printing medium 112 when the ink droplets of the last inkjet are not dried, thereby causing deterioration of the printing quality. . Especially when printing documents with high-quality photos, because the printed ink drops are concentrated in the same position, the printed photos will look very natural. Therefore, when printing the phase > 1 product S, the material is usually a plurality of colors stacked to achieve a high density printing resolution 'so the photo is printed in multiple colors under each other, if not through the signal (4) 'Unexpected conditions will be played in the same coordinates, there will be a problem, that is, if the ink drying time is not enough, another color will be stacked up will cause the problem of dizziness and quality degradation. Called 1521 Therefore, how to develop a method of improving inkjet control that improves the learning and learning of technology is an urgent problem to be solved. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide an inkjet control method for high-density mutual stacking, which uses a control signal to perform appropriate phase shift adjustment, and to print and print in a plurality of mutually exclusive printing operations. The printing inks produced by the printing side (four) in the straight direction are not in the same position as each other and overlap each other with a small area, so that the position of the ink drops on the printing is more messy. The ink method looks more natural: and the area of overlap between each ink drop is smaller than that of the conventional ink jet method, so there is no ink drop of the next ink jet when the ink droplets of the ink jet are not dried yet. Immediately sprayed on the same position as the print media. This will not only improve the print resolution of the inkjet printer, but also print more beautiful photos when printing high-quality photos: text:. In order to achieve the above objectives, one of the more broad aspects of the present invention provides an inkjet control method for overlapping density. The complex (five) ink holes are used to print ink dots while receiving control signals, wherein each - The inkjet actuation signal (PS) of the control signal printed by the ink dot of the mouth is adjusted for appropriate time displacement: the normal time is early or delayed, and the next time the inkjet printing is printed (4) = = ink motion signal ( PS) is the normal time output 'make each adjacent print operation procedure' to make the ink dots to be printed in the vertical position with the printing medium moving port not overlap each other - a small part Area. Another aspect of the present invention is to provide a high-density mutual stacking inkjet control method, the plurality of ink-jetting holes, when receiving control signals for mutual printing, the plurality of ink-jetting holes a plurality of ink dot control is sprayed in a direction perpendicular to a moving direction of the printing medium, wherein one of the two adjacent ink dots is inkjet actuation signal of the control signal of the printing of each inkjet dot (PS) The appropriate time shift adjustment is performed earlier or later than the normal time, and the ink jet actuation signal (PS) of the next alternately printed control signal is a normal _ time output; and the two adjacent ink dots The other ink point is the inkjet actuation signal (PS) of the first printing control signal of each of the mutually imprinted ink dots being the normal time output, and the next time the inkjet printing control signal is inkjet. The actuation signal (PS) is adjusted for appropriate time displacement, which is earlier or later than the normal time; the adjacent printing sequence is printed under the adjacent printing process, and the two adjacent printing ink dots are printed on Position perpendicular to the moving direction of the printing medium This is not the same position spaced. Φ [Embodiment] Some exemplary embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It is to be understood that the present invention is capable of various modifications in the various aspects of the present invention, and the description and illustration are in the nature of In general, the inkjet head 25 has a plurality of ink ejection orifices, and the plurality of inkjet orifices are controlled by a plurality of address signals of the controller 21 and a plurality of inkjet actuation signals, and six orifices are normally printed. Print the straight line, this is the most basic control method, as shown in the third figure, where the address signal AhA6 10 1321521 is used to select the inkjet hole to be inkjet, and the inkjet motion signal PS is decided to be Whether the ink-jet hole of the ink-jet is selected to be ink-jetted, so under normal printing, when the ink-jet head 25 moves to the pi position of the printing medium 112 at time tla, the first address signal A1 is enabled. The high potential of the signal, and the inkjet actuation signal PS simultaneously become a high potential representing the enable signal at time t1, so that the plurality of ink ejection orifices of the inkjet head 25 are in the pi longitudinal position of the printing medium 112. The first ink dot 251 is ejected. By the way, the second ink dot 251 to the sixth ink dot 256 are ejected at the pi longitudinal position of the printing medium 112, so that the six nozzle holes sequentially eject the first ink dot 251 to the sixth ink dot 256. Print a straight line. Therefore, when printing print quality, printing is usually a combination of multiple colors to achieve high-density printing resolution, so when printing photos in multiple colors, it is ideal if it is not controlled by signal. In the situation, the same coordinate will be played. There is a problem that if the ink drying time is not enough, the other color will be stacked up, which will cause the problem of dizziness and quality degradation. In order to improve the printing resolution of the inkjet printer, the printing control method is set to four overlapping printings, and the number of overlaps can be a multiple of two, which is the most basic control method. That is, the ink dots to be ejected onto the printing medium 112 and positioned in the direction perpendicular to the moving direction of the printing medium are divided into four overlapping printing modes. In order to illustrate the technology of the present invention, the technique of the present invention is illustrated by taking an example of an inkjet control method of six address signals and inkjet actuation signals. However, this embodiment is merely an example of a position of one of the partial regions to be printed on the printing medium 112, but is not limited thereto. Of course, the inkjet control method of the present invention can also be controlled by a plurality of address signals 11 and a plurality of nozzle inks to control the plurality of times. Referring to the fourth figure, the ink is ejected. The controller of the embodiment provides a preferred timing sequence for the first method of the inkjet head (4) to the wave of the signal _ to the inkjet head 25; the circle - the control ΑΗ 6 and the nozzle ink actuation signal ps, in the second position The inkjet control system of the address signal will be the second, the second, the case, the case pS\255 " : Γ: the sequence diagram can be seen), that is, in the first, the second fifth inkjet hole When moving to the printing medium U2 = the ink ejection orifice to be positioned in the vertical direction, the ink ejection time of the body movement is relatively unchanged, so that 1 ink dot 256 or the like does fall on the p2 position of the printing medium 112. Inter-heart output 'so it will be compared to 4 for the use of this case inkjet - signal waveform when the two ink points 254 and the first point % ~, a 'point 252, fourth" timing circle can be seen), that is, in the second When the hole and the sixth ink-jet hole move beyond the printing medium 112, the second ink dot 252, the fourth ink dot 254, and the second position of the second ink dot 254 on the printing medium Zhao u2 are left, and the first Ink: two 6 12

As can be seen from the sixth figure, in the present case, the second and third printing operations are performed, so that the second and third printing inks are generated at the position Ρ2 perpendicular to the moving direction of the printing medium. The points are not in the same position and overlap each other by a small area. Referring to the seventh figure, which is a schematic diagram of the waveform timing of the control signal supplied to the head of the ink jet head for the fourth time by the controller of the preferred embodiment of the ink jet control method of the present invention, with respect to the ink ejection position. In the present embodiment, at the time of 131321521 fourth inter-printing, the inkjet control method of the present invention slightly introduces the ink ejection time of the second ink dot 252, the fourth ink dot 254, and the sixth ink dot 256. Some, that is, before the second and fourth ink ejection orifices and the sixth ejection orifice have not moved to the position P2 of the printing medium U2, the second ink dot 252, the fourth ink dot 254, and the sixth ink are made. The dot 256 falls on the right side of the printing medium 112 at the position, and the ink ejection time of the first ink dot 251, the third ink dot 253, and the fifth ink dot 255 is not advanced, and is output for the normal normal time, so the correct φ spray The ink is at the p2 position of the print medium 112. 〇 As can be seen from the seventh figure, in this case, the third and fourth printing operations are performed, so that the third and fourth printings are produced at the position p2 perpendicular to the moving direction of the printing medium. The ink dots are not in the same position of each other and are mutually rich " a small part of the area. In summary, the high-density mutual stacking inkjet control method of the present invention uses the control signal to make appropriate time shift adjustment, and in several overlapping printing operations, the printing is to be printed in the direction perpendicular to the moving direction of the printing medium. The position of the inkjet ink dots is not in the same position and overlaps each other by a small amount of area, which makes the ink drop position on the printing ink more messy, and because of this, the printed photo will be more traditional than the inkjet method. It looks more natural, and the area of overlap between each ink drop is smaller than that of the conventional inkjet method, so there is no ink drop from the last inkjet when it is not dry yet. The same location problem. This will not only improve the print resolution of the inkjet printer, but also print a more natural look when printing a document with a high quality photo.
