Separate the causes
Adhesive reaches the face
Map spots against the fusible’s adhesive pattern and inspect the full layered assembly.
Equipment contamination
Check clean control material processed on the same equipment under an approved trial.
Surface appearance changes
Compare side lighting and nap direction; a compressed surface may look spotted without adhesive penetration.
Steps before deciding
- Identify shell roll, fusible lot and adhesive side.
- Retain unfused, newly fused and cooled specimens.
- Record validated equipment settings and actual trial conditions.
- Ask the fusible supplier to review compatibility before changing settings.
- Approve bond, handfeel and face appearance after care.
Worked example
Hypothetical example: spots also appear on a clean control without fusible. Investigate equipment contact before attributing all marks to adhesive strike-through.
Buyer questions
Can I lower temperature until spots disappear?
An unvalidated reduction may leave an inadequate bond; review the complete process.
Is a peel result enough?
No. Face appearance and garment-care compatibility remain separate gates.
