The characteristics of art paper itself determine that in the field of packaging and printing, it is not the value of reprinting products based on printed images. Instead, it takes full advantage of the unique 61 colors and textures of the art paper, and then appropriately designs it. The unique glossiness and color difference of art paper will bring people different feelings. When these different paper cows are combined with the design, they need the designers to create their own art. They use the personality of the art paper to convey the design intent, make the paper's personality part of the design, and perfectly harmonize with the style of the design, thus displaying the unique art. effect. In the prepress design, the following points should be noted.
1. According to the characteristics of the product, select the appropriate art paper
When designing, we should make full use of the emotions and emotions expressed by the original lines and colors of art paper, and achieve a simple and beautiful artistic effect through the simple design of the finishing touch. Therefore, sometimes it is not necessary to reproduce the effect of the product with a large area of ​​printed text, which can also save printing costs and reduce costs. For example, choosing a colorful art paper, and matching the inks according to the characteristics of the product, will make the ink color contrast with the paper color and achieve the purpose of attracting customers' attention.
2. Understand the silkiness of art paper, and consider the stiffness required for product packaging
Effective use of art paper strength, toughness, stiffness and better elasticity characteristics, increase the appearance of packaging products stiffness, improve product quality. In the design of the carton, it is often necessary to confront ordinary paper with art paper. At this time, attention must be paid to the direction of the paper. It is a common practice to align the plain paper as the liner with the direction of the silk of the art paper to increase the stiffness of the carton.
3. Use special post-printing processes
Mainly used embossing, UV glazing, hot stamping and other processes. Because of the long fiber content in art paper, it has good stiffness and toughness, and is suitable for embossing processing to improve the artistic effect and grade of the product. Many art papers have a rich texture and a special discretionary texture. This feature can be used to make a sharp contrast with the gloss produced by UV varnish in order to achieve special artistic effects.
4. The choice of printing method
If the product is required to have a bright color and the ink layer is thick, screen printing should be considered. However, if you want a clear feeling, you should consider using offset printing. The choice of printing method will have an important impact on the final product.
5. Printing ink selection
Many customers use silver ink and gold ink for printing in order to pursue a gorgeous appearance. In general, gold and silver inks are used mainly in the field parts or in color blocks. It is better not to design gold or silver for very small intaglio texts, yang texts, and gradations. In the process of plate design, the order arrangement of gold and silver ink should be taken into account to ensure the metallic color. Also consider the requirements for gold and silver ink for art paper. If the absorption of the ink on the art paper is strong, the linking material will soon be absorbed, and the metal pigment in the ink will float on the surface of the art paper, lose its luster, attach weakly, and even fall off. The strong acid art paper easily reacts with the metal powder, causing discoloration and loss of luster in the metal pigment. When printing gold and silver ink on art paper, it is usually necessary to first coat the background ink. For example, when printing silver ink, first lay a light layer of white ink. This can not only improve the gloss of the silver ink layer, but also strengthen the silver ink on the paper. Adhesion. Some products, after printing gold and silver inks, should also consider UV glazing or water-based glazing or lamination to prevent oxidative discoloration or shedding of metallic pigments.
