Multi-colour artwork can shift when a polyester-Lycra jersey stretches between print stations. The result is a coloured halo, an offset logo or an irregular outline even when each screen was accurately made. This guide explains what to verify before bulk garment production.
Why This Polyester Fabric Issue Matters
Multi-colour artwork can shift when a polyester-Lycra jersey stretches between print stations. The result is a coloured halo, an offset logo or an irregular outline even when each screen was accurately made.
What Causes the Problem?
Fabric tension, platen adhesive, screen sequence and curing temperature must be considered together. A panel that elongates during the first impression may not recover to the same position for the next colour. Highly open or textured knits can also make fine edges look less sharp.
How to Inspect or Test It
Print a registration target on actual production fabric, not just paper. Compare measured displacement in both directions before and after curing. Test a representative dark and light shade if the finishing treatments differ, and wash the garment to check whether edge alignment stays acceptable.
How Manufacturers Can Prevent It
Use stable panel handling, repeatable platen positioning and controlled off-contact distance. Avoid excessive squeegee pressure that stretches the knit. Allow consistent flash settings and validate artwork trapping so minor movement is less visible.
What Bulk Fabric Buyers Should Specify
Ask the printer for the approved registration tolerance, a cured strike-off and a washed sample. Specify fabric composition and stretch range. Fine outlines on highly elastic polyester can require artwork simplification.
Practical Quality-Control Workflow
Start with an approved reference sample and record the polyester construction, GSM, width, lot and processing history. Inspect at least one representative specimen from each relevant production or finishing lot. Use the same documented test procedure for approval and repeat testing. If a result falls outside the agreed limit, quarantine the affected quantity, identify the process change and retest a corrective sample before restarting mass production.
Common Mistakes to Avoid
Do not approve a bulk lot solely because one swatch looks satisfactory. Do not use universal numerical tolerances without specifying the test method or customer requirements. Avoid changing multiple settings simultaneously during troubleshooting, because that makes root-cause analysis unreliable. Finally, keep the tested fabric linked to its production lot so successful results are reproducible.
Frequently Asked Questions
Does this issue affect all polyester fabrics? No. Risk depends on yarn, knit structure, finishing and intended application.
Can visual inspection replace testing? Visual checks are useful for screening, but agreed performance claims usually require repeatable testing.
When should buyers test? During development, before bulk approval and again when fabric, process or supplier conditions change.
Conclusion
The right approach combines suitable polyester fabric selection, documented testing and consistent factory control. Buyers sourcing fabric for T-shirts, jerseys, uniforms and activewear can explore options at Walrus – Yes India Can and provide their specific performance requirements before ordering.
