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