As the outer packaging of the product, colored boxes are often decorated after printing to improve their performance and appearance quality.
For various post-printing processing methods such as embossing, concave-convex, UV, glazing, grinding, laminating, and anodized aluminum hot stamping, the die-cutting process is an indispensable basic process.
Embossing technology
The embossing process is generally suitable for hardcover color boxes, and the process design is generally: embossed and coated semi-finished copperplate paper, molded with the paper box substrate-gray paper, and then molded. The color box adopts embossing method to improve the decorative quality effect of the product.
The embossing process in packaging and printing plants generally adopts special embossing machines. The process should be noted:
Do not heat and emboss the cover to avoid blistering. If the equipment is equipped with embossing rollers and the pattern design is not satisfactory, or there is no special embossing machine, the computer can be used to personalize the embossing. The solid resin plate is used to make the plate, and then the offset printing machine or letterpress machine is used to adjust the embossing. The process effect will also be very good. When using, pay attention to the suitability and uniformity of the embossing process pressure, and it is better to have clear lines and strong textures.
Concave molding
The design of the convex-concave technology is generally more suitable for color box products, because the convex and concave graphics have a strong sense of relief, which improves the quality of the product to a certain extent. For cartons that need to be framed, do not design bumps. Focus on the quality level, sales, logistics and other characteristics of the product, comprehensively consider, and adopt the corresponding processing technology.
The carton packaging printing process design should pay attention to the following:
②Food and medicine packaging color boxes should adopt environmentally friendly water and water covering technology to avoid adverse quality consequences.
② Anodized aluminum hot stamping decoration process, its materials are expensive, but the decoration quality is very outstanding, it is an ideal choice for medium and high-end product packaging, and more suitable for hardcover corrugated color boxes or color boxes with white cardboard glass cards as substrates The products are processed after printing.
③For color box products with anodized aluminum hot stamping process, attention should be paid to the proper coating and drying of the ink layer during printing, so as to avoid quality defects such as inability to color the hot stamping or the hot stamping layout.
