Abstract
Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.
Claims19
A method of digital printing, comprising the steps of:
- a. digitally printing a reactive ink set comprising a first reagent, a second reagent and a heat activated dye on a substrate wherein said first reagent is reactive with said second reagent;
- and
- b. subsequently reacting said first reagent with said second reagent to bind said first reagent and said second reagent to said substrate, and heat activating said heat activated dye to fix said heat activated dye to a polymer that is present on said substrate.
