A platt is a resin-based polymer plate onto which the image to be reproduced is engraved. The resin is polymerized under the effect of UV light, polymerization being a chemical reaction that enables uniting different molecules.
- Traditional engraving method :
- Stage 1 : The photoengraver polymerizes the milard and the sole, under the effect of the UV rays
- Stage 2 : Placement of the negative film : the UV rays are diffused through the transparent zones, thereby polymerizing the print zones.
- Stage 3 : The non-polymerized zones disappear when washed with the solvent.
- Method using laser engraving :
- This is the more reliable technique ; the cliches are engraved directly from computer to plate using the laser. The dots are stronger, the spaces resist better and enable a finer print quality.
