摘要： At least one certain primary or secondary color is established that receives special treatment for at least one printing medium. Such treatment may include (1) using more than two drops of primaries per pixel for binary printing of a particular secondary; or (2) binary-printing the chromatic primary or secondary -- but not other hues -- after rendition, by use of a "superpixel"; or (3) application of, in effect, a nonintegral number, greater than one, of ink drops per pixel; or (4) combinations of these treatments. As an example of the first of these treatments -- using inks optimized for plain paper at one drop of ink for primaries and two (one of each of two primaries) for secondaries -- red is printed on transparency film as one drop of yellow ink and two of magenta in each pixel. As to the second treatment, the superpixel is preferably a group of pixels ( e. g. , a two-by-two array) including the target pixel, in which group each pixel is inked and at least one pixel receives at least two drops of ink. In particular -- still assuming inks optimized for plain paper as described above -- to print red on so-called "glossy media" (meaning nontransparent glossy media), one drop each of yellow and magenta is used in each of two opposite corners, and one drop of yellow and two drops of magenta are used in each of the remaining corners. Analogously, to print green on transparency film, one drop each of yellow and cyan is used in each of two opposite corners, and one drop of yellow and two drops of cyan are used in each of the remaining corners; and to print blue on transparency film one drop each of magenta and cyan is used in two opposite corners, and one of magenta and two of cyan are used in remaining corners.

摘要： Images are printed using marks formed in pixel arrays by a scanning print head. Certain special techniques well-suited for plain-paper printing have been found undesirable for use with plastic media; these techniques include so-called "resolution-enhanced technology", bidirectional printing (particularly of black), and optical-density controlled printing speed. At top and bottom of each page or sheet of printing medium, where it is undesirable to operate with the pen partly off the edge of the sheet, and where also the printing medium is constrained from only one direction rather than being held taut beneath the pen, the print mask is rotated while the printing medium is held stationary -- thereby entirely avoiding reliance upon accuracy of print-medium advance.
