Abstract

Printing plate is composed photographically from an image bearing transparency by a device comprising an actinic light source, with a flat platform fitted at a distance from the light source, a feeding device for distributing liquid photohardening compound on the platform, a device for levelling the aplied compound to an even thickness and a transparent film carrier with a flat side and a clamp for fixing an image-bearing transparency in contact with the flat side, so that the film holder can be fitted between the actinic light source and the platform. Specifically, the liquid hardening compound consists of a polyene containing at least two reactive unsatd carbon-carbon bonds per mol, a polythiol, contng at least two thiol gps per mol, and a hardening accelerator, the total accumulated functionality of the reactive unsatd carbon-carbons bonds per mol. in the polyene and the total thiol gps per mol in the polythiol being more than 4.
