Lithography TRIZ Cases
- Negative-Working Printing Plate Precursor With Ozone-Blocking Layer
An outermost ozone-blocking layer protects the infrared absorber from discoloration, preserving on-press plate precursor performance after storage.
- Lithographic Plate Coating with Asymmetric IR Dye Dispersion
Asymmetric IR dye substitution prevents aggregation in photopolymer plate coatings, improving sensitivity, adhesion, and press life.
- On-Press Lithographic Plate Precursor with Ozone-Resistant Outer Layer
A water contact angle above 36° and a polymer outer layer help resist ozone discoloration while limiting development residues.
