Corrugated cardboard boxes for flexographic printing require original design
The manuscript is the basis of printing. For corrugated cardboard boxes that use flexographic printing, the design of the manuscript has the following requirements. (1) During the printing process, the ink volume and pressure required for large areas and small text, thin lines, dots and other details are not the same, so even if they are the same color, do not put them on the same printing plate. Should be separately plate printing. (2) When performing full-page printing on a corrugated cardboard box, in addition to the pressing effect of the embossing roller on the corrugated cardboard, the ink also has a wetting effect on the paper surface, which reduces the compressive strength of the corrugated cardboard box. . (3) It is not advisable to overprint two color blocks of the same shape and size, so as to avoid overprinting, and local text, patterns or small color blocks should be overprinted on the solid color block with a larger area. (4) Avoid designing wide and long bars and solids along the axial direction of the printing plate cylinder, which will cause machine vibration; in addition, avoid the band pattern in the same direction as the corrugated cardboard corrugation, otherwise the printing pressure will crush the corrugation , Causing the carton to break. (5) When designing the layout, large circular patterns should be avoided. Otherwise, the printed patterns will become elliptical due to the flexographic elongation in the circumferential direction. (6) For the negative characters, especially the small ones, the strokes should be thickened consciously to avoid the strokes becoming thinner or even muddled due to ink spreading during printing. (7) Generally speaking, texts with an area of ​​less than 2cm2 cannot be seen beyond a distance of 5cm. For corrugated carton printing, the meaning of publicity and promotion of goods is lost. Therefore, the design should avoid using too small text. (8) Avoid precise overprinting of tight stitches. The two-color overprinted parts generally need to be trapped with 0.1 ~ 0.2mm to avoid whiteness when the overprint is poor. (9) Minimize the number of overprints, generally less than 3 colors. The greater the number of overprints, the more severe the compressive strength of the corrugated box decreases. Practice has proved that after single-color printing, the compressive strength of corrugated boxes decreases by 6% ~ 12%, and after three-color printing, the compressive strength of corrugated boxes decreases by 17% ~ 20%.
More and more people choose Plastic Storage Boxes when they choose to store their containers, whether they are household goods or office supplies. Because the Plastic Storage Box makes it light and easy to handle because of the material, and the well-designed box makes the space utilization rate high, it gradually became one of the first choices for storing goods. Because the material of the plastic storage box is generally ABS, PC, etc., it results in a box that is cheap and durable.
