The influence of roll-to-roll laminator on printing quality mainly includes the following:
1. If the surface roughness of the printed matter is too high, it will affect the castability (leveling and spreading) of the adhesive, resulting in uneven coating, and the product surface after filming will have bright spots or "fogging" with different gloss.
2. The printed film laminator with poor flatness is prone to wrinkles, and due to the unevenness of the paper, the adhesive cannot be evenly coated on the paper, resulting in film peeling and blistering.
3. It is inevitable that chemical syrup will be used in the printing process, and it is easy to change the surface structure of the paper, so that the adhesive and the paper cannot be in good contact, causing the product to foam after being placed for a long time.
4. Roll-to-roll laminator Note: The product should be stored for a period of time after printing to facilitate the evaporation of paper moisture. Otherwise, after the film is evaporated, the paper fibers shrink as the water evaporates, which will cause the film to wrinkle.
5. The adhesive layer of the printed surface of the laminating machine is dried to the initial dry when the peritoneum is in place, and the thickness is about 0.002mm ~ 0.003mm. Therefore, if the powder sprayed on the printing material is too thick, it will cause a thin snowflake shape on the product due to the incomplete pressure spot.

6. If the ink layer on the surface of the printed matter is too thick or not dry, the adhesive applied by the roll-to-roll laminating machine during the lamination cannot penetrate through the pores between the ink layer and the paper to bond, and false bonding will occur. , Causing the finished film to foam in a short time.
