Reflective Print How to Read It on a Lab Report
Laboratory reports present Reflective Print in a compact format. Knowing what each line means prevents misreading.
Definition reminder
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.
Common report layout
The report states method EN ISO 20471 retroreflection, sample description, conditioning, and the measured result. 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.
Typical result
Values near above 100 cd/lx/m2 retroreflection usually indicate a conforming lot, assuming the fabric matches the sample submitted. 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.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. 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.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. 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.
