Acceptance criteria for finished products a) Standard 1, color, pattern, model and sample of the finished product or the same requirements for the product. 2. The pinholes are positive and symmetrical, and the needle pitch and pinhole size meet the standards. 3, photometry meets the requirements. 4. There is no car-frying, no car-breaking, and uneven thickness on the back. 5, according to style, color, pattern, type packaging.
