How should print rub resistance be tested?
Define dry or wet condition, contact material, load, cycles and visual or colour-transfer limit for the actual printed and finished surface.

Checklist
Quality evidence to define before production
- Rub and abrasion
- Ink and substrate interaction
- Surface coating
- Test method
- Target quantity and SKU allocation
- Approval sample and decision owner
- Required date and Mainland China delivery point
- Change and repeat-order record
Quality control
Four elements of an auditable inspection plan
Rub and abrasion
Set dry or wet rub method, load, cycles and acceptance appearance for the actual ink, coating and delivery environment.
Ink and substrate interaction
Check absorption, opacity, drying, odour and rub performance on the actual substrate, not only on a screen proof.
Surface coating
Clarify coated, uncoated, varnished or laminated surfaces because ink holdout, rub resistance and recyclability can change.
Test method
Name the method, conditioning, equipment, units and pass criteria; words such as strong or durable are not measurable specifications.
Execution method
Four actions from RFQ to production
Translate expectations into criteria
Use dimensions, tolerances, test methods and defect photographs.
Inspect at the right stages
Place controls at incoming material, first article, in-process and final release as risk requires.
Record traceable results
Identify lot, SKU, sample size, inspector, tools, findings and disposition.
Close corrective actions
Contain affected stock, verify root cause and confirm the fix before repeat release.
FAQ
Questions buyers often ask
How should print rub resistance be tested?
Define dry or wet condition, contact material, load, cycles and visual or colour-transfer limit for the actual printed and finished surface.
What should be written in the specification?
At minimum, define Rub and abrasion, Ink and substrate interaction, Surface coating, Test method, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
