On-site generation of processless thermal printing plates using reactive materials

摘要

The traditional trade-off between performance and shelf-life of processless thermal printing plates can be eliminated by using reactive chemicals which are mixed during (or just prior to) application to the plate and imaged shortly thereafter. The utility of high power thermal exposure heads combined with the advantages of mixing two reactive chemicals, allows the generation of high performance processless thermal printing plates on-site, effectively eliminating the requirements of shelf-life and robustness. Furthermore, the process of mixing the reactive chemicals is ideally suited for on-press imaging.
