Talk about the dot printing of corrugated boxes

In order to adapt to the development and changes of the market economy and enhance the competitiveness of products, many corrugated box layouts have begun to use dot graphics to highlight products. Enriched the layout, but also improved the packaging level of the product. In the packaging design, the expressiveness and visual impact of the graphics are strong, and it is easy to attract people's attention. The graphics printed by the dots are difficult to counterfeit, have good anti-counterfeiting performance, have a sense of hierarchy, and have a three-dimensional sense, which is pleasing to the eyes. To get high-quality dot effect, you must first work hard on the manuscript: For corrugated carton printing, too dense dots are easy to cause paste phenomenon; too thin dots will lose graphic details and affect graphic effects. Make sure to grasp accurately . There are two types of graphics: vector graphics and bitmaps. The processing of dots is different. For vector graphics, it is necessary to control the gray level and reflect the hierarchy through grayscale changes. The size of grayscale determines the size and density of dots. Process the scanned image. After it is completed, it is converted to grayscale mode, and then processed by the color halfone in the filter Pixelate in PHOTOSHOP. The size of the dots should be adjusted according to the grayscale of the graphics through the parameters in the color halfone dialog box to obtain the dot graphics suitable for the printing conditions. After processing the vector graphics and bitmaps, the negative film used for printing must be output through the output center. The number of output lines also determines the important parameters of the number of graphics dots. The larger the number of network lines, the more the number of dots. The number of network cables. In the process of making dot graphics, it is necessary to consider the grayscale graphics of the vector graphics and the number of output network lines, and the halftone processing graphics of the bitmap and the number of output network lines to obtain the overall net shape effect. In general, try to avoid printing dot pattern and large-area color block pattern in the same block as much as possible. If large-area color block pattern and dot pattern are printed separately, pressure adjustment and color control are much simpler. After the design draft is output as a negative film, the plate can be made. The resin plate used to make the dot pattern requires a high hardness of 45. -50. Shore A is suitable, and the material's low elasticity and slow recovery of denaturation can ensure good reproducibility of the dot pattern. The production of dot resin plates on the same product packaging should be carried out at the same time and completed at one time. It is very easy to have the difference in the depth of dot printing and produce different effects in batching. If the halftone version cannot be processed at one time, the back exposure, main exposure, rinsing, drying, debonding and post-processing time must be strictly controlled during plate making to keep the data of each process consistent so as to obtain the same effect of halftone resin version. When designing the dot pattern, it is also necessary to consider the number of screen lines of the anilox roller of the enterprise printing machine. It is very important to select the anilox roller correctly, which determines success or failure. The ironing roller is the most common type. With the widespread use of anti-squeegee blades and the promotion of new high-speed printing machines, the rapid wear of the anilox roller is a problem. Many companies have begun to use wear-resistant ceramic ink rollers. Its high demeanor is conducive to dot graphics printing. When the same color printing includes full version and halftone dots, the thickness of the full version can be increased by 0.15-0.30mm, which is beneficial to improve the plate pressure and printing pressure. There will be dot expansion phenomenon during printing, which requires the printer to adjust the pressure as lightly as possible to obtain the minimum dot expansion, and make detailed records of the parameters adjusted by the printing machine so that the same printing effect can be tracked later. After printing, the dot resin plate should be cleaned immediately to prevent the ink from drying on the plate surface, causing dot clogging and causing bad plates.
