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 flexographic printing plate, is widely used in the 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. Enhance print quality corrugated boxes: Starting a corrugated flexo printing forms mainly from corrugated printing plates printed with several different forms carton printing plate, the most commonly used offset printing, flexo printing / flexo printing and pre-printed. In addition, with the rapid development of digital printing technology, and now there are companies introduced specifically for corrugated printing digital printing equipment. In these types of printing methods, offset printing, pre-printed and digital printing is mainly used for printing color box. Which, after completion of offset printing, laminating machines will need to use wall paper printed paper corrugated board; preprint sucked tissues used in the production of corrugated board before the tile line on good printing, such production out of cardboard is patterned; the digital printing is already done directly on the surface of corrugated board printing. This cost of production is higher in several ways plate, capable of printing relatively attractive products, which is why these mainly for reasons of printing color box printing. Compared to color box, currently used in transport packaging are some of the more relatively simple pattern cartons, the cartons are mostly water-based flexo presses or direct printing of corrugated board has a good system. It should be noted is that water-based flexo presses and in fact is not a scientific definition of letterpress plate making, but the concept of convention. Because water-based printers can either use a rubber printing, flexographic printing can also be used, of course, relatively harsh flexographic printing presses, flexographic use only and can not use a rubber version.
