Definitions

  • This invention relates generally to color inkjet printing methods and apparatus, and more particularly, to bi-directional color inkjet printing methods and apparatus.
  • Color printing typically involves the application of one or more base colors onto an area to give the area the appearance of a desired color.
  • Display techniques commonly use the primary colors, red, green and blue, as the base colors.
  • Printing techniques commonly use the secondary colors, cyan, magenta and yellow, as the base colors.
  • Color printing with an inkjet pen involves ejecting multiple drops of the base colors onto an area to give the appearance of a desired color. Black also is used with the base colors for inkjet printing to improve the color appearance and to enable black, or gray-scale. printing.
  • the base colors used in inkjet printing techniques are abbreviated as KCMY for convenience, where K represents black, C represents cyan, M represents magenta. and Y represents yellow.
  • a bi-directional color printing mode is achieved in which colors are applied to a media in the same order, regardless of which direction the inkjet pen is moving relative to the media. Hue shifts are avoided. Color hues for a given desired color are the same for each line printed.
  • an initial or first pass of color printing onto virgin paper i.e., paper area with no ink on it
  • virgin paper i.e., paper area with no ink on it
  • Printing a second pass then occurs while the inkjet pen moves in the opposite direction across the media sheet.
  • an initial pass of color printing onto virgin paper is achieved by alternately feeding the paper forward and backwards along the media path between each successive print pass.
  • a minus one-half (0.5) line feed occurs for second pass printing.
  • a positive one and one-half (1.5) line feed occurs for a first pass onto another virgin portion of the media sheet.
  • the -0.5, +1.5 line feeds alternate after each printing pass assuring that the first pass printing always occurs on virgin paper, and that the second pass overlays ink from an earlier first pass.
  • a color inkjet printhead has its inkjet nozzles positioned in symmetrical fashion.
  • a conventional color inkjet printhead there are two rows of nozzles which eject black dots, then two rows of nozzles which eject cyan dots, then two rows of nozzles which eject magenta dots, and then two rows of nozzles which eject yellow dots.
  • the printhead prints in YMCK order while moving in one direction and KCMY direction while moving in the opposite direction.
  • a symmetrical printhead of this invention there is one row of nozzles which ejects black dots, followed by one row of nozzles which ejects cyan dots, followed by one row of nozzles which ejects magenta dots, followed by two rows of nozzles which eject yellow dots, followed by one row of nozzles which ejects magenta dots, followed by one row of nozzles which ejects cyan dots, followed by one row of nozzles which ejects black dots.
  • the printhead prints in the order KCMYYMCK regardless of which direction the inkjet pen moves across the media sheet.
  • the aspects of this invention apply to color inkjet printing devices, including desktop color inkjet printing devices, portable color inkjet printing devices and larger sized color inkjet printing devices, such as plotters.
  • Printing devices include printers, fax machines, copiers or other ink emitting devices used in forming characters, symbols or graphics onto ink receiving media, such as paper, transparencies or cloth.
  • An advantage of this invention is that color inkjet printing of desired quality is achieved with fewer passes, and thus at faster speeds.
  • Fig. 1 shows an inkjet color printing apparatus 10.
  • the printing apparatus 10 is part of an inkjet printer, fax machine, or copy machine.
  • a shuttle carriage 12 carries one or more inkjet pens 14. In one embodiment there a four pens each for printing a different color. In another embodiment there is one pen for printing each of four different colors. Typically the colors are black, cyan, magenta and yellow. In other embodiments the primary colors red, green and blue may replace cyan, magenta and yellow or replace black, cyan, magenta and yellow.
  • the ink reservoirs 16-22 are in a given arrangement. At one external position is the black ink reservoir 16. Next to the black ink reservoir 16 is the cyan ink reservoir 18. Next to the cyan ink reservoir 18 is the magenta ink reservoir 20. At the opposite end, next to the magenta ink reservoir 20, is the yellow ink reservoir 22.
  • the specific arrangement of the reservoirs 16-22 may vary.
  • Fig. 2 shows a printhead 24 having four portions 26-32. Alternatively, these four portions 26-32 may represent four printheads 26-32. Each portion includes multiple rows of inkjet nozzles. All nozzles of a given portion print ink of the same color.
  • Printhead portion 26 includes multiple rows 34 of nozzles 42 which eject black ink.
  • Printhead portion 28 includes multiple rows 36 of nozzles 44 which eject cyan ink.
  • Printhead portion 30 includes multiple rows 38 of nozzles 46 which eject magenta ink.
  • Printhead portion 32 includes multiple rows 40 of nozzles 48 which eject yellow ink.
  • the shuttle carnage 12 moves along a rail 50 under the control of a carriage controller 52. Ink drops are ejected from the nozzles under the control of printhead controller 54.
  • a media 56 is fed along a media path by a set of rollers 58.
  • An axle 60 for the rollers is driven by a motor 62.
  • the motor is controlled by a media transport controller 64.
  • the carriage controller 52 moves the shuttle carriage 12 along the rail 50 in a first direction 70, while the printhead controller 54 causes inkjet nozzles 42-48 to fire.
  • the printhead portion 32 for printing yellow ink is the lead portion as the carriage 12 moves across the media 56 in direction 70
  • ink is printed for a given row in the order yellow, magenta, cyan and black (YMCK).
  • the media transport controller 64 moves the media 56 into position for another row of printing.
  • the carriage controller 52 then moves the carriage 12 back across the media 56 along the rail 50 in a second direction 72, opposite the first direction 70, while the printhead controller 54 causes the inkjet nozzles 42-48 to fire again.
  • the printhead portion 26 for printing black ink is in the lead position during travel in direction 72.
  • the ink is printed in the reverse order black, cyan, magenta and yellow (KCMY).
  • Fig. 4 shows a diagram of the printhead 24 movement and color printing order for a conventional bi-directional four pass color printing method.
  • the media transport controller 64 causes the media 56 to advance by one-quarter of a line feed (+1/4 LF).
  • a line feed (+1/4 LF).
  • all colors KCMY may be ejected.
  • CMY may be ejected.
  • pass 1 the carriage 12 moves in one direction 70 and ink is applied in the order YMCK. A 0.25 line feed then occurs.
  • pass 2 the carriage 12 moves in the opposite direction 72, and ink is ejected in the order CMY.
  • a 0.25 line feed then occurs.
  • Fig. 5 shows a diagram of the printhead 24 movement and color printing order for a bi-directional two pass color printing method using a similar methodology as for the four pass method in Fig. 4.
  • a one-half line feed (+1/2 LF) occurs after each pass.
  • all colors KCMY may be ejected.
  • pass 1 the carnage 12 moves in one direction 70 and ink is applied in the order YMCK.
  • a 0.5 line feed then occurs.
  • the carriage 12 moves in the opposite direction 72, and ink is ejected in the order KCMY.
  • a 0.5 line feed then occurs.
  • Row 102 receives ink in the order: YMCK, KCMY. It has been found that the hue shifts which occur due to this variation in the order which the colors are applied for each half-line are readily perceptible, and therefore result in unacceptable print quality. Accordingly, an alternative approach is needed to achieve desirable color print quality for a two pass color printing methodology.
  • Fig. 6 shows a diagram of the printhead 24 movement and color printing order for a bi-directional two pass color printing method according to an embodiment of this invention.
  • all colors KCMY may be ejected.
  • printing occurs onto a virgin area of the media 56 only while the carriage moves in the direction 72 relative to the media 56.
  • virgin area it is meant a blank or previously unprinted area, or an area of media background (e.g., watermark, design background).
  • a minus one-half line feed (-0.5 LF) occurs after printing in such one direction.
  • a positive one and one-half line feed (+1.5 LF) occurs after printing in the opposite direction.
  • One skilled in the art will appreciate that printing onto virgin paper only while printing in one direction also could be achieved for multiple pass printing of more than two passes. Different line feed motions would be used. For example, in a four pass printing mode the line feed would be minus one-quarter of a line feed (-0.50 LF) after printing in the one direction onto a virgin area, and plus three-quarters of a line feed (+1.00 LF) after printing in the other direction. Note that while printing in the one direction only one-half of the swath prints onto the virgin area.
  • the degree of negative linefeed and positive linefeed while scanning or printing may vary for different embodiments.
  • the positive linefeed is greater than or equal to one (i.e., Pos LF ⁇ 1.00), while the negative linefeed is less than or equal to 2 divided by the number of passes in the printing mode minus one (i.e., Neg. LF ⁇ (2/num passes) - I)
  • each row receives ink in the same order: KCMY,YMCK.
  • This order may vary and be any prescribed order. However, the prescribed order is the same for every row printed. As a result, there are no hue shifts among the rows which can be attributed to the order the colors are applied to the media.
  • half of the print swath will be blanked so as not to print during the first occurrence of printing in the direction 70 (e.g., pass 2).
  • row 110 does not receive ink and is either off the media, in the media margin, or in an unprintable area of the media.
  • the prescribed color order is a hierarchical order. For example if printing in a direction 70 occurs in the order YMCK, then for a given area of the media, yellow ink is received before magenta, cyan or black ink; magenta ink is received before cyan or black ink; and cyan ink is received before black ink.
  • the actual order of the ink as applied is MCK. If instead there is no magenta ink for such area, then the actual order is YCK.
  • ejecting ink in a first prescribed color order refers to the hierarchy. One or more colors in such hierarchy may be omitted. If the hierarchy is YMCK, though, no other color would print before yellow for a given area receiving yellow ink.
  • Fig. 7 shows an alternate printhead 124 embodiment for the inkjet pen 14 of Fig. 1.
  • the printhead 124 includes multiple rows of inkjet nozzles. Each row is dedicated to printing ink of a given color. The rows are arranged in symmetrical fashion according to color.
  • the outer rows 34 print ink of the same color (e.g., black).
  • the inner rows 36 adjacent to the rows 34 print ink of another color (e.g. cyan).
  • the next inner rows 38 print ink of another color (e.g., magenta).
  • the innermost rows 40 print ink of the fourth color (e.g., yellow).
  • the order in which the ink colors print is the same regardless of which direction 70, 72 that the printhead moves.
  • the print order of the colors is KCMYYMCK when the printhead 124 moves in direction 70, and is the same when the printhead 124 moves in the opposite direction 72.
  • Fig. 8 depicts a two pass bi-directional color printing method in which a carriage 12 carries a pen 14 having the printhead 124.
  • a one-half line feed (+1/2 LF) occurs after each pass.
  • all colors KCMY may be ejected.
  • pass 1 the carriage 12 moves in one direction 70 and ink is applied in the order KCMYYMCK.
  • a 0.5 line feed then occurs.
  • pass 2 the carriage 12 moves in the opposite direction 72, and ink is ejected in the same order KCMYYMCK.
  • a 0.5 line feed then occurs.
  • the carnage 12 moves in the one direction 70 again, and ink is applied in the order KCMYYMCK.
  • a 0.5 line feed then occurs.
  • pass 4 the carriage 12 moves in the opposite direction 72, and ink is ejected in the order KCMYYMCK.
  • a 0.5 line feed then occurs.
  • Rows 106-114 are active rows receiving ink.
  • Row 106 is a blank region in the margin or off the media.
  • Each row 108-112 receives ink in the order, KCMYYMCK, during each one of two passes.
  • the cumulative order for any such row 108-112 is KCMYYMCK, KCMYYMCK. Because the prescribed color order is the same for every row printed, there are no hue shifts which can be attributed to the order the colors are applied to the media 56.
  • One advantage of this invention is that hue shifts are avoided among multiple lines of a print job. Color hues for a given desired color are the same for each line printed. Another advantage of this invention is that color inkjet printing of desired quality is achieved with fewer print passes. As a result faster print speeds are achievable.
