A non-impact process and apparatus for coating printing cylinders with layers of a coating liquid, especially for coating flexographic printing sleeves with infrared sensitive layers.

Process for coating on printing cylinders

This invention makes available a photopolymerizable material containing at least one polymeric binder, photopolymerizable monomer and, at least one photoinitiator, and having a special shear modulus and a specific thickness. These photopolymerizable materials are used in processes for preparing images, especially multiple color proofs. Temporary supports and pigmented transfer materials specifically designed for the preparation of multiple color proofs are described. A pigmented element having a pigmented transfer layer with a polymeric component of polycaprolactone, polytetrahydrofuran and mixtures thereof is disclosed.

Multiple color proof temporary supports, photopolymerizable materials and pigmented transfer materials

This invention makes available processes for preparing images, especially color proofs. A layer with imagewise tacky and nontacky areas is toned. Toner adhering to the tacky areas is transferred first onto a temporary support and from there onto an image receptor.
