Abstract:
A method for obtaining a high quality printing plate by spraying a spray solution on a receiving surface, which is not a grained and anodized aluminum surface, wherein the pressure factor (PF) is lower than 200 mN/m, whereinPF=P/dÃ—(&sgr;+&thgr; mN/mÂ°) PF: Pressure Factor (mN/m) P: Spray Profile (mm) d: distance between spray head and receiving surface (mm) &sgr;: surface tension (mN/m) &thgr;: Dynamic contact angle of the receiving surface with water at 2 s contact time, and wherein the spray solution comprises hydrophobic thermoplastic polymer particles and a compound capable of converting light into heat.
