Considering print registration

Highlight color is implemented by rendering a separate bitmap in the AFCCU for black and for the highlight color to be printed. A bitmap is a two-dimensional array of 0's and 1's.

shows how a bitmap is placed on the physical form. The origin (0,0) is the location at which the scan direction and process direction begin. The term "scan direction" refers to the direction in which the Infoprint 4000 and Infoprint 4100 printers generate image across the form. The scan direction is perpendicular to the to the direction in which the forms are moving through the printer. The term "process direction" refers to movement through the various stages of the printer's imaging system, and is parallel to the direction in which the forms are moving through the printer.

While the Infoprint 4000 and Infoprint 4100 printer 1 is imaging everything to be printed in black, a separate bitmap for highlight color is passed to printer 2. When designing a highlight color application, the accuracy with which the Infoprint 4000 and Infoprint 4100 printing system's Printer 1 and Printer 2 can place the bitmaps with respect to each other must be considered.
