  1. Make a document: Before any Foldable Magnetic Cardboard Packaging Giftbox is produced and printed, you must make a document, design the document, design the Foldable Magnetic Cardboard Packaging Giftbox printing file, and complete the selection of the Foldable Magnetic Cardboard Packaging Giftbox material.


  2. Publishing and printing: After designing the Foldable Magnetic Cardboard Packaging Giftbox and printing the document, you can directly publish it. There are two ways: one is to directly output the CTP, but the film. After finishing, directly determine the machine according to the color printed on the Foldable Magnetic Cardboard Packaging Giftbox, cut the paper, and then print.


  3. Surface treatment of printed sheet: After printing the paper, the surface of Foldable Magnetic Cardboard Packaging Giftbox should be treated in various ways to ensure the durability of Foldable Magnetic Cardboard Packaging Giftbox. Common surface treatment methods are: oil polishing, laminating (light glue / dumb glue), UV, bronzing, etc.


  4. Mounting pit: Foldable Magnetic Cardboard Packaging Giftbox printed sheet is pitted after surface treatment. The mounting pit is printed and surface treated with paper + cardboard / pitting paper (based on the proofing time, it is suitable to be resistant to breakage. (Transformer material)


  5. Beer / die-cutting: first, the die making, the die need to be determined according to the template and the printed semi-finished product. After determining the die map, sticking the adhesive, and confirming that the finished product is correct, you start to use the beer machine to carry beer. After the beer is good, you need a large waste paper.


  6. Foldable Magnetic Cardboard Packaging Giftbox sticking / nailing: Fix the Foldable Magnetic Cardboard Packaging Giftbox with glue according to the template, or glue it according to the template.


  7. Pack and ship Foldable Magnetic Cardboard Packaging Giftbox using kraft paper or cardboard boxes!

  Foldable Magnetic Cardboard Packaging Giftbox printing color film is not bright because of one: the amount of glue

  When using stretch polypropylene film coating. The film must be glued. The amount of glue is applied to a moving film by a driving steel roller installed in a plastic box through a rotating belt. The amount of glue is controlled by a steel blade that falls on the steel roller. Large amount of light glue: small amount of heavy glue. The amount of glue must be well grasped, it can be uniformly covered without generating crystal points. If the amount of glue is too large, the coated product will be dull.


   In the process of gluing, special attention must be paid to prevent the tiny particles and foreign matter from remaining in the rubber disc after the gel has solidified. If it is left, it will be picked up by the gluing roller during rotation and stuck on the rubber blade, and a non-gluing white print will appear here. Therefore, after a long-term shutdown of the laminating machine, before the laminating machine is started, the rubber pump and the rubber bucket should be cleaned with laminating water or high boiling point kerosene to ensure that the glue of the gluing roller is normally applied to the film without generating Traces.


  Foldable Magnetic Cardboard Packaging Giftbox printing color film is not bright for two reasons: temperature control is not appropriate


  When laminating different substrates, the temperature of the electric heating steel drum must be adjusted according to the product covered. If the coated substrate is gold cardboard, the temperature of the laminated steel drum should be controlled at 70-80 ° C. If it is a gray whiteboard covered with 250g / m2 or 300g / m2, the temperature should be adjusted to 80-90 ° C. In the process of placing the white paper, the moisture absorbed by the white paper far exceeds that of the gold cardboard. Especially in rainy days and winter, if the temperature adjustment is not appropriate, the coated products will not shine. When laminating, there is sometimes noticeable water droplets or steam on the silicon roller, which is caused by the paper absorbing a large amount of moisture. The film temperature of such products must be increased further. For a harvested product, the temperature of the drying tunnel can be controlled at 50 ~ 60 ° C. Use a finger-coated film to stick the test at the exit of the drying tunnel without any visible traces, just a little sticky. If the film temperature is too high, it will blister. Therefore, the temperature of the heating steel drum must be controlled according to the characteristics of the product when laminating.


  Foldable Magnetic Cardboard Packaging Giftbox printing color film is not bright because of three reasons: insufficient pressure


  According to the needs of customers, the thickness of substrate materials is not consistent. When laminating, the pressure between the silicone roller and the steel roller should be adjusted according to the thickness of the substrate paper. If the pressure is too small, the film of the laminated product is not firm, bright, and easy to produce wrinkles: too much pressure will cause film wrinkles and paper deformation.


  Foldable Magnetic Cardboard Packaging Giftbox printing color film is not bright four reasons: keep the drum clean


  After long-time compressing, the steel drum is in direct contact with the film, plus the effect of temperature, some residues will remain on the steel drum. The silicone roller is in direct contact with the back of the paper of the product to be covered. In addition to the separation of the paper feed distance, a lot of glue is directly pressed onto the rubber roller to cause accumulation, which will affect the brightness of the product covered.


  In severe cases, wrinkled products can also be caused. Therefore, we must keep the drum clean and stop cleaning at any time to ensure the quality of the coated product.
