Problems solved by technology

While the use of dithering techniques or in situ mixing techniques is effective in greatly expanding the range of possible colors obtainable from a given set of process colors, it has been found that the process colors - the specific colors of process dyes - the choice of the color has a dramatic effect on the range of colors achieved with a relatively limited number of process colors

Embodiment Construction

[0042] According to an exemplary embodiment, an initial step in using the system described herein is to identify the process colorants to be used, and the in-situ mixing that can be obtained from the particular combination of process colorants. Combinations of these colorants comprise dithering palettes, from which dithering software is readily available to create a larger apparent palette of perceived colors. Typically, a 50 / 50 mix involving two colorants is used (i.e., two consecutive applications of colorant in the same pixel, each at 50% of the substrate saturation or relative absorption capacity level), but it is also contemplated to show two colorants. other relative proportions of colorants, or mixtures involving three or more colorants. These processing colorants, together with the in situ mixing of the available large amounts of such colorants, constitute a palette from which the available dithering algorithm can be derived from the target image (i.e., the pattern to ...

Abstract

A process by which dithering techniques and in situ blending techniques may be used to reproduce a desired multi-colored dyed pattern on a substrate using precisely delivered quantities of liquid colorants that are available in only a relatively few colors. Specific preferred process colors, as well as procedures for expanding the range of reproduced colors using such process colors, are presented Optionally, specific actuation instructions for a specific dye injection machine capable of patterning a moving textile substrate may be generated.

Description

[0001] Cross References to Related Applications [0002] This application is based on provisional application 60 / 287,772, filed May 1,2001. [0003] The present invention relates to a processing method by which a desired multi-color dyeing pattern can be designed and arranged on an object to be dyed, and the method uses precisely quantitatively delivered liquid colorants which use only a few colors . In particular, the present invention relates to a method in which a relatively small number of liquid dyes are used which collectively comprise a limited choice of process colors. Designing an electronically encoded pattern and applying the pattern to a selected textile substrate in combination with color extension techniques are among preferred embodiments incorporating the method of the present invention. In preferred embodiments using the method of the present invention, specific motion commands can be generated for use with specific dye jet machines capable of generating patte...
