What should I do if the printing of the plastic box packaging is not true, but the font part will be pasted
Jul 24, 2023
Many manufacturers who produce transparent plastic boxes, color printing plastic boxes, pvc plastic boxes, pet plastic boxes, pp plastic boxes, frosted plastic boxes, bronzing plastic boxes, and plastic box packaging occasionally encounter false printing during the production process of UV color printing. The black printing is not true to the naked eye, and the actual black is the same as the full-page red under a magnifying glass. The reason is that the surface layer of the film has not been processed well. After adding ink, the improvement is good, but the font part will be blurred. How can we achieve both when the raw materials cannot be changed? One: If conditions permit, the font part and the solid bottom layout should be printed in groups. It is best to improve the ink. If the customer's requirements are not very strict, you can raise the solid bottom layout a little bit or hollow out the font part. The disadvantage of this is that the solid layout may appear ghosting due to excessive up and down pressure or damage the carton structure and affect the physical performance. Or you can make the viscosity of the ink lower but drive as fast as possible. Two: If the printing effect ink has foaming. It should be that the defoamer is added too much and the printing pinholes. Three: Increase the color content, reduce the viscosity, and speed up the vehicle. Four: Adjust the eccentricity, when the knife is cut up and down, it is not the tip of the knife to the tip of the knife! Improving the adjustment of the above steps can basically improve. In the production process, it is inevitable that various problems will be encountered, so the production factory must strictly control the procurement of raw materials. Try to avoid unnecessary losses caused by bad raw materials to the production process.
