Description of the invention: [Technical field to which the invention pertains] Suitable for ink jet printing The present invention relates to an ink jet method, and more particularly to a high density stacked ink jet control method of a machine. [Prior Art] ^+In recent years, with the popularity of personal computers and the rapidity of the Internet = Inkjet printers have become very popular peripheral devices, widely used in homes, personal studios, and even in various walks. The main advantages of the jet riding machine are low price, low noise during operation and excellent printing quality, and can be printed on various printing media, such as general paper, special inkjet printing paper, photo paper and special projection. Film and so on. As we all know, there are many factors that affect the quality of inkjet printing, such as the composition of ink, the choice of paper, and the way of ink supply. However, the inkjet printer's inkjet method is a good choice for inkjet printers. The printing quality of the machine, in pursuit of more perfect quality, the relevant developers have invested a lot of time and effort to improve the inkjet printing method of inkjet printers, in order to meet the requirements of high printing quality and high-speed printing. In order to make the print quality natural, inkjet printers usually use masking (MASK) on the firmware control when printing with the same month quality, so that the order of printing different colors at the same point is more messy. In order to make the finished product natural, but because of the control of the firmware of the control end, the printer also includes the factor of the mechanism and the quality of the nozzle, so in order to make the print quality more natural, in addition to the firmware end mask (MASK) In addition to the control, the "control 6 200900254 system" of the injection end is added with the length control of the Firing pulse to make the position of the ink droplets printed on the print more scattered and natural.

At this time, the controller 21 provides a control signal to the inkjet head 25 having the h number (four) ink holes (nGzzles), so that the ink is printed on the position where the P1 P media 112 is currently to be printed in the printing area, When the == list action is performed, the print medium 112 can be printed. However, the method of controlling the nozzle ink is to print the rain print resolution and the high print speed of the dpi or higher. When the ink droplets of the last inkjet G have not been dried, the ink droplets of the next ink jet are immediately sprayed on the same position of the printing medium 112, thus causing deterioration in print quality. Especially when printing a document with a South quality photo, the printed photo will look unnatural because the ink drops are concentrated in the same position. Therefore, when printing the quality of the print, the mouth print is usually a combination of multiple colors to achieve high-density print resolution, so when the print is printed, multiple colors overlap each other, and if it is not controlled by the signal, it is ideal. In the situation, the same coordinates will be played. There is a problem that if the ink drying time is not enough, another color will be stacked to cause a problem of dizziness and deterioration of quality. 8 200900254 Control =: ί:: Two inkjets with the above-mentioned conventional technology are missing. [Summary of the Invention] The main purpose of the present invention is to provide a high: fall = use the control signal to make the appropriate time shift; the whole 'make the ink-cutting points that are printed in the direction perpendicular to the moving direction of the printing medium are different from each other - The positions of the positions and the weights of each other will be more natural than the conventional ink method, and the area of each 丄/3 overlap is smaller than that of the conventional inkjet method, so when the ink droplets are not dried yet The next ink drop of the inkjet immediately = the same position in the same print media. In this way, without printing the print resolution of the ink printer, in the print of a high-quality photo: ¥, the printed photo will look more natural. ~i 达 达 Descend the purpose of the present case - a more general implementation of the method is to provide a kind of inkjet control method The printing of the ink dot = the inkjet signal (PS) of the shouting is made to adjust the displacement of the time, which is earlier or later than the normal time, and the inkjet motion field of the control signal printed next time (PS) ) is the normal time output, so that the printing ink dots to be printed in the position perpendicular to the moving direction of the printing medium are not in the same position and mutually mutually under each other in the adjacent printing sequence. Overlap '^ a small area. 200900254 Another broad embodiment of the present invention provides a high-density mutual stacking inkjet control method, wherein the plurality of ink-jet holes are printed and printed while receiving control signals, and the plurality of ink-jet holes are printed and printed. a plurality of ink dot control is sprayed in a direction perpendicular to the moving direction of the medium, wherein one of the two adjacent ink dots is at an appropriate time for the inkjet actuation signal (PS) of the control signal of the printing of each inkjet dot The displacement adjustment is earlier or later than the normal time, and the inkjet actuation signal (PS) of the next alternately printed control signal is a normal time output; and the other ink point of the two adjacent ink dots Then, the inkjet actuation signal (PS) of the first printing control signal of each of the mutually imprinted ink dots is output at a normal time, and the inkjet actuation signal (PS) of the control signals printed next time alternately is printed. Perform appropriate time displacement adjustment for early or delayed output than normal; make each adjacent sequence of alternate printing operations, and the two adjacent inkjet dots are printed and printed with the printing medium Directions in the vertical direction Not in the same position.

The high potential, so that the plurality of ink ejection orifices of the inkjet head 25 eject the first ink dot 251 at the pi, the longitudinal position of the printing medium 112. And so on, in the pi longitudinal position of the printing medium 112. The second ink dot 251 to the sixth ink dot 256 are ejected, so that the six ink jet holes sequentially eject the first ink dot 251 to the sixth ink dot 256* to print a straight line. Therefore, when printing the print quality, the printing is performed. Usually, multiple colors are stacked one on another to achieve high-density printing resolution. Therefore, when the photo is printed, multiple colors overlap each other. If the signal is not controlled, the next coordinate will be played, and there will be one. The problem is that if the time is not enough, the other color will be stacked again, causing the fainting and causing the mouth. The problem of gradual decline is produced. In order to improve the printing resolution of the inkjet printer, the printing method is printed in four overlapping sheets. The number of overlaps can be a multiple of 2, and the control mode is ίΐί Also, the ink dot which is to be ejected to the printing medium m in the direction perpendicular to the moving direction of the printing medium is divided into four times, and the ink jet control method of six address signals and = actuation signals is taken as an example.

A schematic of the location. In the present embodiment, at the time of the second inter-printing, the inkjet time of the second ink dot, the fourth ink dot 254, and the sixth ink dot 256 is slightly delayed (such as the fifth image). The PS timing diagram shown can be seen, that is, when the second and fourth ink ejection orifices and the sixth ejection orifice move beyond the p2 position of the printing medium 112, the second ink dot 252, the fourth is made. The ink, the dot 254, and the sixth dot are dropped to the left of the p2 position on the printing medium 112, and the ink ejection time of the first dot 251, the 12th 200900254, the second dot 253, and the fifth dot 255 are unchanged. , for normal normal time output, so it falls correctly on the location of the print media ί12. ^ As can be seen from the fifth figure, in the case of the first and second alternate printing operations, the first and second times are produced at the position ρ2 perpendicular to the direction of movement of the column (four) body. The ink dots do not overlap each other in a small area. Referring to the sixth figure, the control signal provided by the controller of the preferred embodiment of the ink jet control method of the present invention is applied to the inkjet head for the third time, and the order is relative to the ink ejection position. The schematic is in this embodiment. When the first-person is suitable for printing, the inkjet control method of the present invention delays the ink ejection time of the first ink point, the third ink point 253, and the fifth ink point slightly. The first ink dot 251, the second ink dot 253, and the fifth ink dot 255 are caused to fall when the first and third ink ejection orifices and the fifth ink ejection orifice are moved over the position of the printing ink 112. The print medium 112 is on the left side of the position, and the second ink dot 252, the fourth ink dot 254, and the sixth ink dot 256 Ο 2 ink time are not delayed, and are output for normal normal time, so the correct print media is printed. 112 at the p2 position. ^Di six maps can be known, this case is the second and third times of the imprinting = private order 'the second and third times in the direction of the printing media moving direction = P2 position produced printing The ink dots are not in the same position - the positions overlap each other by a small portion. Please refer to the seventh figure, which is a schematic diagram of the wave sequence of the control signal of the second mutual printing with respect to the inkjet position, which is provided by the controller of the preferred embodiment of the inkjet control method of the present invention. . In the present embodiment, at the time of the fourth inter-print printing of 13 200900254, 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 p2 position of the printing medium 112, 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 spray The ink is at the p2 position of the print medium 112. As can be seen from the seventh figure, this case is to print the second and fourth times in the direction perpendicular to the printing direction of the printing medium. The ink dots are not in the same position with each other and overlap each other by a small portion.

Under several overlapping printing operations, the printing is to be perpendicular to the moving direction of the printing medium. The position = the ink dots are not in the same position and overlap each other with a small part of the surface ^ so that the ink drops are more messy, and because of this, the printed photo will look better than the traditional ink method. More natural and the area between each two drops is smaller than the traditional inkjet method, so there will be no upper ink droplets when the ink droplets are not dry yet. When the image of the inkjet printer has been improved, the printed photo will look more natural and conform to the various patent requirements. Anyone who is familiar with this technology will be modified as a whole, and will not be removed as intended by the scope of the patent application. 200900254 [Simple description of the diagram] The first picture: it is a schematic diagram of the structure of the inkjet printer.
