Abstract
Abstract A method is provided for jet printing in a plurality of colors on a substrate which is coated with one component of a dye. The jet printing nozzles direct droplets of liquid to the substrate containing the complementary dye components which produce a finished dye at the points of impact of the liquid onto the substrates. Different jet printing nozzles utilize different complementary dye components on the same substrate, producing different dyes and thereby different colors.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
193 words
A method of printing a multicolor image on a non-absorbent, transparent substrate comprising providing a first jet printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said first jet printing nozzle and said substrate while ejecting from said first jet printing nozzle and toward said substrate a first stream of individual image forming liquid droplets comprising a first image forming resin-free composition, providing at least a second printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said second jet printing nozzle and said substrate while ejecting from said second jet printing nozzle and toward said substrate a second stream of individual image forming liquid droplets comprising a second image forming resin-free composition, each of said first and second image forming compositions containing a different substantially colorless material capable of being converted to a colored material by reaction with a chemical agent, and said substrate having a surface transparent coating comprising a resinous binder containing a chemical agent capable of converting said first image forming composition to a material of one color and said second image forming composition to a material of another color.
Claim 2
Independent Claim
193 words
A method of printing a multicolor image on a non-absorbent, transparent substrate comprising providing a first jet printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said first jet printing nozzle and said substrate while ejecting from said first jet printing nozzle and toward said substrate a first stream of individual image forming liquid droplets comprising a first image forming resin-free composition, providing at least a second printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said second jet printing nozzle and said substrate while ejecting from said second jet printing nozzle and toward said substrate a second stream of individual image forming liquid droplets comprising a second image forming resin-free composition, each of said first and second image forming compositions containing a different substantially colorless material capable of being converted to a colored material by reaction with a chemical agent, and said substrate having a surface transparent coating comprising a resinous binder containing a chemical agent capable of converting said first image forming composition to a material of one color and said second image forming composition to a material of another color.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein said first and second streams are ejected toward said substrate at the same time.
Claim 4
Independent Claim
196 words
A method of printing a multicolor image on a substrate comprising providing a first jet printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said first jet printing nozzle and said substrate while ejecting from said first jet printing nozzle and toward said substrate a first stream of individual image forming liquid droplets comprising a first image forming composition containing a first azo coupling agent, providing at least a second printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said second jet printing nozzle and said substrate while ejecting from said second jet printing nozzle and toward said substrate a second stream of individual image forming liquid droplets comprising a second image forming composition containing a second azo coupling agent, each of said first and second image forming compositions containing a different substantially colorless material capable of being converted to a colored material by reaction with a chemical agent, and said substrate having a surface composition comprising a diazonium salt capable of converting said first image forming composition to a material of one color and said second image forming composition to a material of another color.
Claim 5
Independent Claim
196 words
A method of printing a multicolor image on a substrate comprising providing a first jet printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said first jet printing nozzle and said substrate while ejecting from said first jet printing nozzle and toward said substrate a first stream of individual image forming liquid droplets comprising a first image forming composition containing a first azo coupling agent, providing at least a second printing nozzle at a fixed distance from said substrate, providing relative transverse movement between said second jet printing nozzle and said substrate while ejecting from said second jet printing nozzle and toward said substrate a second stream of individual image forming liquid droplets comprising a second image forming composition containing a second azo coupling agent, each of said first and second image forming compositions containing a different substantially colorless material capable of being converted to a colored material by reaction with a chemical agent, and said substrate having a surface composition comprising a diazonium salt capable of converting said first image forming composition to a material of one color and said second image forming composition to a material of another color.
