DTF PET Film

CIAC(Coating Ink Absorption Capacity): Evaluates the ink absorption uniformity and saturation of film coatings at optimal print ink levels, detecting the integrity of ink spreading and the absence of overpenetration in darker areas.

CIQ(Color Imaging Quality): Through the standard ICC curve output and four-color composite test, color reproduction, color gamut coverage and imaging consistency are examined to ensure that the printed image is accurate and free of abnormal color deviation.

PRI(Powder Residue Inspection): Examine the patterned transfer area and the blank area under microscopic conditions and record the amount of powder adherence and edge neatness to ensure that there is no excess powder, clumping or edge contamination.

FLTA(Film Layer Thickness Accuracy): The thickness of the film layer is measured using a high-precision thickness gauge to verify that the deviation from the standard design value is within tolerance, ensuring the structural stability of the finished product and the consistency of heat transfer performance.

WRP(Weather Resistance Performance): The thermal stability of the film is tested under the specified baking temperature and time conditions to observe whether there is any deformation, scorching, cracking or color peeling to ensure the durability in processing and outdoor applications.

SSAQ(Surface & Structural Appearance Quality): Examine the coating integrity, surface finish and packaging condition of the membrane on the front, back and edge areas to ensure that there are no scratches, tears, coating defects or contaminants.

POP(Peel-Off Performance): Evaluate the peeling smoothness and film residue after transfer according to the standard peeling test method to ensure that there is no residual film or adhesion on the surface after transfer and that it meets the standard peeling definition.

CPA(Continuous Printing Adaptability): Simulate long time continuous printing scenarios, detect whether the film material in the feeding, transfer and ink bearing process, such as warping, jamming, coating drumming or paper feeding deviation problems.

OR(Overall Rating): The Overall Rating represents the weighted average of all evaluation indicators, providing a single, clear measure of the product’s overall performance and quality level. It helps you quickly understand how the product performs across all tested criteria. Each indicator is scored from 0-8, with a composite score from 7-8 considered good, 4-7 considered moderate, and 0-5 considered poor. Integral scores are assessed upwards (e.g., 7 is considered good).
