Sublimation Printing Setting It Correctly on a Tech Pack
Sublimation Printing should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
heat transfer of disperse dyes onto polyester. Working figures for Sublimation Printing normally sit around 190-210 degrees transfer in mainstream production. Note calender heat press on the tech pack so nobody tests against an older revision.
Target value
Open the specification at 190-210 degrees transfer, adjusted to the end use. Record elastane content alongside Sublimation Printing, because blends shift the measured value. A result outside 190-210 degrees transfer usually points to process drift rather than to the fibre itself.
Method line
Always pair the target with calender heat press so the mill and the laboratory test the same way. Keeping reference values for Sublimation Printing lets suppliers quote without extra sampling rounds. Ask for conditioning details together with calender heat press, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Sublimation Printing normally sit around 190-210 degrees transfer in mainstream production. Note calender heat press on the tech pack so nobody tests against an older revision.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. Record elastane content alongside Sublimation Printing, because blends shift the measured value. A result outside 190-210 degrees transfer usually points to process drift rather than to the fibre itself.
