Quality Control
With 27 years of expertise and a multi-stage quality inspection system, we minimize defects.
Quality Control Process
Jeil Decal minimizes defects such as scratches, delamination, blocking, and curling through quality management at every stage—before, during, and after the transfer process.
STEP 01Incoming Material Inspection (IQC)
- 01COA/LOT history verification for fabrics, release paper, and inks
- 02Base film thickness, width, and winding condition check
- 03Surface inspection for contaminants, gels, and scratches
- 04Physical property verification (tensile, shrinkage, heat resistance)
- 05Incoming quantity verification and material LOT tracking registration
STEP 02Print Process Color/Registration
- 01Color difference management (ΔE standard vs. reference sample)
- 02Print registration error verification
- 03Coating condition inspection (bleeding, pinholes, mis-transfer, scratches)
- 04First article approval (limit sample/approval sample comparison)
- 05Process condition recording (tension, drying temperature, line speed)
STEP 03Adhesion Test · Adhesive Properties
- 01Adhesion test (peel strength) measurement and standard verification
- 02Initial adhesion and aging change verification
- 03Post-transfer adhesion state, lifting, and delamination check
- 04Post-heat adhesion retention and transferability evaluation
STEP 04Slitting/Cutting Dimension Inspection
- 01Slitting width and cutting dimension measurement
- 02Winding tension, cross-section condition, and curl check
- 03Slitting cross-section and dust generation verification
- 04Process defect aggregation and LOT-based tracking
- 05Post-processing surface contamination and impression check
STEP 05Outgoing Inspection OQC · Approval
- 01Final appearance and functional inspection per AQL standards
- 02Shipping specification, inspection report, and approval spec matching
- 03Packaging condition, quantity, and winding direction final check
- 04Label verification (product name, LOT No., manufacture date, spec)
- 05Final pass judgment and quality manager approval
- 06Shipping approval issuance and inspection history archiving
