Abstract
Abstract The present invention provides a method of printing a digital image on a textile including the steps of selecting 8 to 16 inks to form an ink set, calibrating the ink set to create an ink set profile, using the ink set profile to calculate hue and shade-based look-up tables directly correlating the inks with the color space coordinates of the pixels of the digital image. The present invention also is a system and an apparatus performing the calibration of the ink set and direct correlation of the color space coordinates. The printed fabric has a first plurality of dots having 8 to 16 differently colored inks per dot and a second plurality of dots having one color per dot. Significantly, the present invention produces printed textiles having a high detail, deep color, and broad shading, as well as a combination of dyes heretofore considered incompatible.
