Sublimation Printing Test Methods and Acceptable Limits
Sublimation Printing is verified through calender heat press. Knowing how the method works avoids rejecting fabric that actually meets the requirement.
Method overview
calender heat press defines sample size, conditioning and calculation, so values are comparable only within the same revision. Working figures for Sublimation Printing normally sit around 190-210 degrees transfer in mainstream production. Note calender heat press on the tech pack so nobody tests against an older revision.
Result interpretation
Read the value together with construction notes; 190-210 degrees transfer is only meaningful for similar fabrics. Record elastane content alongside Sublimation Printing, because blends shift the measured value. A result outside 190-210 degrees transfer usually points to process drift rather than to the fibre itself.
Typical limits
Buyers commonly write 190-210 degrees transfer with a stated tolerance, then verify against calender heat press. Keeping reference values for Sublimation Printing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with calender heat press, since both affect the reading.
Sources of variation
Conditioning time, operator technique and shade all influence the result. Working figures for Sublimation Printing normally sit around 190-210 degrees transfer in mainstream production. Note calender heat press on the tech pack so nobody tests against an older revision.
Documentation
Record the standard revision on every report, because older versions can differ from current practice. Record elastane content alongside Sublimation Printing, because blends shift the measured value. A result outside 190-210 degrees transfer usually points to process drift rather than to the fibre itself.
