摘要:
Lithographic printing plates are imaged using an inkjet printer to imagewise apply a chemical or masking agent onto the plate surface. In some embodiments, the chemical causes an affinity change, thereby facilitating lithographic printing.

摘要:
A process for imaging a lithographic printing plate by ink jet printing imagewise a near infrared absorbing material onto a coated plate. The plate is then exposed to near infrared emitters followed by developing the coating.
摘要:
A method for preparing a substantially uniformily dyed photosensitive composition useful in the reprographic arts, and compositions useful therefor. A water soluble basic dye is reacted with an organic acid, or an ammonium or alkali metal salt thereof which is preferably monofunctional and the reaction product is substantially uniformly dissolved in a photosensitive diazo composition to impart the desired dye color thereto. The resultant dye colored photosensitive composition may then be coated upon a suitable support, for example, a film or metal sheet, to provide a photosensitized product useful in the reprographic arts, which possesses substantially uniform color characteristics and extended shelf life.
