Ponte Roma Setting It Correctly on a Tech Pack
Ponte Roma should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
stable double knit with fine ribs. Working figures for Ponte Roma normally sit around 250-320 GSM in mainstream production. Note double knit machine on the tech pack so nobody tests against an older revision.
Target value
Open the specification at 250-320 GSM, adjusted to the end use. Record elastane content alongside Ponte Roma, because blends shift the measured value. A result outside 250-320 GSM usually points to process drift rather than to the fibre itself.
Method line
Always pair the target with double knit machine so the mill and the laboratory test the same way. Keeping reference values for Ponte Roma lets suppliers quote without extra sampling rounds. Ask for conditioning details together with double knit machine, since both affect the reading.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. Working figures for Ponte Roma normally sit around 250-320 GSM in mainstream production. Note double knit machine 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 Ponte Roma, because blends shift the measured value. A result outside 250-320 GSM usually points to process drift rather than to the fibre itself.
