FIELD: process engineering.
SUBSTANCE: invention relates to processing of polymers, particularly, to thermal development of light setting blank of type form for production of raised raster structure. This blank comprises the ply of substrate, light-setting ply and mask ply removed by laser arranged above the latter. Proposed process comprises removal of mask ply portion by laser, lamination of oxygen-impermeable membrane over mask ply, exposure of the blank by actinic radiation through oxygen-impermeable membrane and mask ply for selective cross-linking and solidification of light-setting ply portions. Then, oxygen-impermeable membrane is removed for thermal development for removal of mask ply and non-solidified parts of light setting ply. In compliance with other versions, negative mask ply can be used instead of mask ply and application of negative mask as oxygen-impermeable ply.
EFFECT: higher quality of raster ply structure.
