Claims
- 1. A method for obtaining a high quality printing plate by spraying a spray solution on a receiving surface of grained and anodized aluminum, wherein the spray factor (SF) is between 48 and 70 mN/m, whereinSF=(P/d×σ) SF: Spray Factor (mN/m) P: Spray Profile (mm) d: distance between spray head and receiving surface (mm) σ: surface tension (mN/m) and wherein the spray solution comprises hydrophobic thermoplastic polymer particles and a compound capable of converting light into heat.
- 2. A method according to claim 1 wherein the spray solution is an aqueous solution.
- 3. A method according to claim 1 wherein the said solution comprises a hydrophilic binder.
- 4. A method according to claim 1 wherein the receiving material is a drum with a grained and anodized aluminum surface, capable of being incorporated in a printing machine.
- 5. A method according to claim 1 wherein the receiving surface is a grained and anodized aluminum surface mounted onto a drum.
- 6. A method according to claim 1 wherein the spray solution has a viscosity of at least 1.5 mpa.s.
