Reflective Print Frequently Asked Questions
Short answers to the questions buyers ask most often about Reflective Print.
What does it mean?
glass bead or silver layer for visibility. Working figures for Reflective Print normally sit around above 100 cd/lx/m2 retroreflection in mainstream production. Note EN ISO 20471 retroreflection on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from above 100 cd/lx/m2 retroreflection and adjust for the end use of the garment. Record elastane content alongside Reflective Print, because blends shift the measured value. A result outside above 100 cd/lx/m2 retroreflection usually points to process drift rather than to the fibre itself.
How is it tested?
EN ISO 20471 retroreflection. Keeping reference values for Reflective Print lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN ISO 20471 retroreflection, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Reflective Print normally sit around above 100 cd/lx/m2 retroreflection in mainstream production. Note EN ISO 20471 retroreflection on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Reflective Print, because blends shift the measured value. A result outside above 100 cd/lx/m2 retroreflection usually points to process drift rather than to the fibre itself.
