The proof is produced via color donors and thermal transfer ( ablation ) onto intermediate carriers or onto the substrate used for the print run.
2.
Electrons are removed from excited chlorophyll molecules and transferred through a series of intermediate carriers to " ferredoxin ", a water-soluble electron carrier.
3.
The true proof systems use color foils that are to be processed in separate units ( laminators ), transferred from intermediate carriers onto production paper and / or laminated, either to protect the proof or to give it the appearance of the surface structure of production paper.
