AI Technical Summary
Existing lithographic printing plate precursors are easily damaged during mechanical processing and automated transportation, resulting in surface damage and reduced printing quality. At the same time, the addition of wax reduces the static friction coefficient, making plate stacking and transportation difficult.
A top coating comprising a hydrophobic binder and hydrophobic discrete particles is employed. The coating hardens upon exposure and is developed during the printing process. The top layer includes a hydrophobic binder and hydrophobic discrete particles, preferably with a particle size between 10 nm and 1000 nm, and a melting temperature above 50°C to improve scratch resistance and reduce the risk of migration.
It significantly improves the scratch resistance and anti-slip properties of printing plates, reduces dampening solution contamination, improves the cleaning behavior during the printing start-up process, and reduces dampening solution consumption.
