Screen Preparation and Engraving Technology
topic
Rotary screen preparation uses UV photoengraving to expose lacquer-coated nickel screens against positive or negative films created from digital design data, dissolving unexposed lacquer in solvent to open pattern apertures, with modern direct laser engraving systems eliminating photographic film by directly ablating screen lacquer with computer-controlled CO2 or fibre lasers at resolutions of 60 to 250 lines per centimetre for tonal and geometric designs.
Role
Converts digital design files into physical printing screens whose aperture pattern determines the print design accuracy, colour sharpness, and tonal range achievable in screen printing, with screen engraving precision and repeat accuracy being critical quality parameters that determine whether the printed fabric meets the designer's intended pattern with correct colour registration and print definition across the full fabric width.
