Registration Control and Print Quality Management
topic
Print registration control maintains accurate positional alignment of successive colour screens to within plus or minus 0.3 millimetres for fashion fabric and plus or minus 0.1 millimetres for high-definition printing, using optical fabric edge sensors, screen position adjustment actuators, and fabric tension control systems that compensate for fabric elongation and distortion during transport through the printing machine under different tension conditions.
Role
Ensures that multi-colour printed designs achieve the sharp colour boundary definition and register accuracy required for the design aesthetic, with misregistration being the most visible print quality defect that causes coloured halos at colour boundaries and blurred design edges that make printed fabric unsuitable for sale, requiring registration control precision proportional to the minimum colour boundary width in the design.
