Printing and packaging industry, printing methods are: offset printing (ink color printing), letterpress printing (carton printing ink). Among them, the cartons printed with a water-based color printing compared to high-intensity, low-cost, high production efficiency (fast delivery), the overall effect is closer to color printing, widely used in transport packaging products. 2, the main production processes corrugated boxes corrugated board automatic production lines, printing processes, post-processing and molding process; the current print job has basically printing, slotting, die cutting, sticky boxes, packaging molding automation. Second, the principle of a water-based printing, flexo printing belong additive color printing. Color document through the electronic color separation plate into negative image, and then print through the press, the ink is transferred from the press anilox roll to the printed version, and then transferring the ink from the printing plate to the corrugated board. By trapping, overlapping color to give a positive image to achieve the original sample box of copy, reproduce the original quality. 5, when the plate thickness of the uneven quality of the fault caused uneven thickness when the rubber plate, plate layout will be the height difference. Layout high place it is easy to paste version, the layout of the place is prone to low ink failure, causing imprinting is not clear, in order to avoid this undesirable situation, the plate can be sporadic way, the plate is made of several pieces, should use the same piece of media for production plate, respectively, so that its thickness difference is relatively small. If you have a good system flexographic flexographic platemaking, the presence of the thickness difference in the local thin plate on the back more than make up for viscose fabric layer, so that the whole plate to maintain a substantially uniform thickness to ensure uniform printing pressure and layout inked . 6, quality failures caused by improper color sequence if the layout of the more full-color illustrations are arranged in the first set of printed carton printing plate, when the process of corrugated cardboard into the next color group organization in a plastic bag printing plate, since the first color set of cardboard inking large printed graphic, slow drying, very easy to make blotted resulting from dirty forum. To prevent the ills generated layout should be arranged in a small area first color set printing, the area of ??the large layout arrangement in subsequent printing color group can avoid causing dirty version blot transfer phenomenon.
