To ensure the printing quality of customized Bubble Film bags, you can start from the following aspects:

Preliminary preparation

Selection of materials: Select the surface of high smoothness, good smoothness, good ink absorption bubble film material. Test the surface tension of the film, and re-corona treatment is required if it is not up to standard. Choose the ink with stable quality, accurate color, strong adhesion and appropriate drying speed, and select the matching ink according to the bubble film material and printing process.

Accurate design: fully communicate with customers, accurately grasp the design needs, clear patterns, text, color and other details. Use professional design software for layout design to ensure clear elements, high resolution, and correct color patterns. Strictly review and proofread the design draft to avoid mistakes.

Printing process control

Debugging equipment: Check the equipment comprehensively before printing to ensure that all components are normal. According to the Bubble Film Thickness, material and printing pattern characteristics, the printing pressure is precisely adjusted to ensure uniform ink transfer. Set the printing speed reasonably to ensure that the ink is fully transferred and dried.

Color management: Establish a color management system and calibrate colors through standard color cards and other tools. A batch of printing products as far as possible to use the same batch of ink, spot color ink a sufficient amount of modulation. Control the amount of ink in the ink tank, add new ink frequently, strictly control the volatilizing rate of the mixed solvent, and fully stir the two-component ink with less frequent distribution.

Plate maintenance: carefully check the plate before printing, clean up oil and other impurities. Clean the plate regularly and deal with the blocking problem in time. When printing volume is large, consider making multiple sets of plates.

Quality inspection

First piece inspection: Before the formal batch printing, make the first sample, check the pattern registration, color, text clarity and other indicators, do not meet the requirements of timely adjustment.

Process sampling: Regular sampling in the printing process, check the stability of printing quality, and find that the problems such as color difference and overprinting are not allowed to be solved immediately.

Full inspection of finished products: After the printing is completed, full inspection or proportional sampling of finished products to remove unqualified products and ensure the quality of outgoing products.
