The quality of the paper will cause the paper machine to be inaccurate
In daily production, when the facial tissues are printed, the contact of each group of fangs is not allowed, causing tearing of the mouth of the facial tissue. When using a paper machine to affix the paper, it is easy to hit the paper into a curved or folded state during the paper feeding process, which will cause the paper to be misaligned with the corrugated cardboard. When this happens, we need to adjust the handover time of the cavities to prevent the paper edge of the tearing paper.
In addition, if the moisture content of the paper is not suitable or the stacking is not neat, it is easy to curl the edge of the paper. At this time, the front working surface on the paper feeding chain and the edge of the paper are not in a straight contact push state. In this case, the paperboard which is pasted will also make the paper obviously protrude from the corrugated cardboard, and the die cutting will be caused by The protruding facial paper is easily bent, causing the front specification to be inaccurate, and the die-cut semi-finished product is also subject to errors. This requires us to control the moisture content of the facial tissue to prevent the water from being high and the stiffness to drop.
There are also semi-finished facial tissues that have been printed, glazed, calendered or coated. We must stack them neatly to prevent deformation and curling. This will avoid inaccuracies when the paper and corrugated paper are attached. Here we also want to remind everyone, pay attention to the characteristics of the usual paper stocking. There must be a quantitative standard for its temperature, humidity, and level of flatness, and strict implementation may result in a loss of a batch of products.
Second, the conventional carton printing method The conventional carton printing methods mainly include flexo, offset and screen printing. 1. Flexographic printing corrugated carton The conventional flexographic printing corrugated carton process is directly printed on corrugated cardboard, using water-based Ink, so some people call this process a watermark. Flexographic direct printing has the following characteristics: (1) Large format. Wide-format flexographic presses have a maximum width of 2.5m to 2.8m. (2) The price is low. The flexographic printing plate has a high print durability and can be reused; the ink price is also low. (3) It can be linked to production, such as printing, grooving, indentation, binding (sticking) box, bundling, etc. (4) The carton strength is reduced less. Since flexo printing is light press printing, the effect on the strength of corrugated board is small. (5) The printing accuracy is not high, the number of conventional offset printing lines is 175 lines/inch, and the number of conventional screen printing lines for flexo printing boxes is 35 lines/inch to 65 lines/inch, which is a low-precision printing method, which is most suitable for printing text lines. The printing quality of four-color images has improved in recent years, but it is still limited. (6) The plate making is easy and difficult, the text line drafting is easy, and the four-color image making is difficult. (7) The printing quality is not stable, mainly reflected in the difficulty of controlling the color of the printing ink. The flexographic direct printing process is suitable for the first type of carton production process and is currently widely used in China's carton factories. 2. Offset printing Corrugated box Conventional offset printing Corrugated box adopts indirect printing method, that is, printing the carton paper first, then attaching the printed tissue paper to the corrugated board. Since the resolution of the PS plate is relatively high, a very fine printed pattern can be printed. At present, the vast majority of high-grade corrugated boxes used for sales in China are offset products. Offset printing corrugated carton has the following characteristics: (1) It is not suitable for paperboard linkage production line, only suitable for single-face corrugating machine, and the production efficiency is low. (2) The format is limited, generally smaller than the width of the flexo carton. (3) The printed products are very fine, and the number of screen lines can reach 150 lines/inch to 200 lines/inch. (4) Easy plate making, regular plate making for the PS version. (5) Surface finishing, such as lamination, glazing, etc., can be performed. (6) High printing costs. (7) The printing quality is relatively stable. 3. Screen printing corrugated box The screen printing corrugated box process uses direct printing. Since the inking rate of the screen plate is proportional to the pitch of the screen, the resolution of the screen printing is not high, the image accuracy is low, and the conventional screen line number is 60 lines/inch to 80 lines/inch. The screen printing corrugated box has the following characteristics: (1) It is not suitable for the linkage production line, and the production efficiency is low. (2) The printing format can be large or small. (3) It is possible to complete the printing before the boxing or boxing, or after the boxing and boxing. (4) Suitable for printing non-fine products. The screen printing ink is thick, so its color saturation is high, and the visual effect is strong, especially in the field and effect of spot color printing. (5) Easy plate making and low plate making cost. (6) Low printing costs. (7) The printing quality is relatively stable.
