Folding carton embossing process

Process characteristics: Embossing and embossing is a common print show decoration process. He uses concave-convex stamps whose graphic information is matched with each other. After mechanical action, the substrate at the corresponding surface of the print is permanently squeezed and deformed. A three-dimensional image is formed on the surface of the product. In recent years, with the continuous improvement of electronic engraving and laser engraving technology, the processing level of the embossed stamp has undergone a quantum leap. The embossed and stamped embossed pattern has made the embossed imprinted printing product The surface of the picture is even more vivid.

Avoidance of quality defects:

(1) Choose the appropriate pressure to ensure that the gravure stamp is pressed evenly when it is pressed together, which can effectively avoid the occurrence of quality defects with unclear outlines.

(2) The use of a graphic with a contour smaller than the outline of the concave stamp and a convex embossing pattern with a smooth edge can effectively avoid the occurrence of quality defects in the profile overprinting.

(3) When using gypsum embossing stamps, gypsum powder and glue with good quality can effectively avoid the occurrence of quality defects such as spots on the surface of the image and brittleness of the plaster embossing die.
