  • Method and system for printing with an inkjet printer to simulate screen printing
    Patent number: 6742869
    Abstract: A system and method are disclosed for ink jet printing of wide format substrates such as textiles in a manner to simulate screen printing, in which image data in one or more acceptable formats is input, transformed into a suitable L*a*b* file format, further converted into a driver format for a printer, then communicated to such printer. Optionally, the color gamut of the image in the L*a*b* file format is checked against an estimated screen gamut of a screen printer, and limited to the estimated screen gamut as required.
