The overall analysis of color printing packaging

  The overall analysis should be made in color printing. The place of color picture and text should be laid on a white background. White can be realized by a white background. Color needs to be hollowed out. Spot-color printing can make the process simpler. If the text and line contents are large, the number of net lines can be lower. Pre press and color separation. Color separation plates are required to be white, used for priming, and the corresponding color plates. This can be done in an electronic engraving system, or in a pre-press design system, and then directly engraved on an electronic engraving machine plate.

  Dalian color printing packaging specific methods of operation: First, the production of a single plastic bag pattern, according to the size of each element in Freehand input text, draw color blocks, lines. Set the corresponding color. After making, check the size, position, text, and make sure there are no errors, then make a large version of the work. Considering the width of the bag, the width of the printing machine and the width of the plastic film, it is calculated that several bags can be printed in the width direction. According to the diameter of the plate cylinder, several bags can be seen in the weekly version. Pay attention to the width between the bag and the bag. Next, engraving and engraving on the electronic engraving machine.

  At the same time, prepare the metal plate. It should be noted that if the seal is used, the graphic and print on the plate are just the opposite. Start printing. Printing is carried out on a modular plastic film printing machine. The specific steps are plate loading, ink scraper, ink preparation, ink blending, roll up, ink test, adjustment and formal printing. Film covering. On a special laminating machine. Bag making. Bagging is actually bonding, two layers of film bonded to form a three-side sealed plastic bag, and cut into a single bag.
