Print Paste Preparation and Colour Kitchen Systems
topic
Print paste preparation systems mix dye with thickener, fixation chemicals, and auxiliaries in defined proportions using automated dispensing and dissolving equipment in centralised colour kitchens, with computer-controlled colour matching recipes generating dye combination instructions from spectrophotometric target measurement and paste viscosity management ensuring consistent rheological properties for reproducible print paste flow through screen apertures.
Role
Provides the consistently formulated print pastes that are prerequisite for reproducible printing quality by eliminating manual weighing and mixing errors through automated colour kitchen systems, with paste viscosity control being critical for rotary screen printing where viscosity variation affects the paste flow rate through screen apertures that determines colour depth and print definition on the printed fabric.
