Analysis on the design and printing points of art paper (Part 1)

art paper, also known as fancy paper or special paper, is very different from ordinary printing paper. This kind of paper has rich colors and unique lines, and is mostly processed by special paper processing equipment and technology. Because of its unique charm, art paper has attracted the attention of businessmen since it entered China in the early 1990s. It is used in exquisite book covers, picture books, brochures, invitations, greeting cards, high-grade office paper, business cards, high-grade packaging paper, etc. At the same time, the usage has also increased dramatically. However, due to the lack of understanding of the structural characteristics and printing performance of art paper, various problems often occur in the application process, resulting in a lot of waste. The following is a discussion on the matters needing attention in prepress design, printing and post press processing of common art paper

design points of art paper

the characteristics of art paper determine that it does not reproduce the value of products mainly by printing pictures and texts in the field of packaging and printing, but makes full use of the unique color d=h plus 0-h color and grain of art paper, and then makes appropriate design. The unique gloss and color difference of art paper will bring people different feelings. When these different paper personalities are combined with the design, designers need to be ingenious and use the individuality of art paper to convey the design intention, so that the individuality of paper can become a part of the design and be perfectly unified with the design style, so as to show the unique artistic effect. In prepress design, we should pay attention to the following points

1. Select appropriate art paper according to the characteristics of the product

make full use of the emotions expressed by the original lines and colors of art paper and Richard Northcote, member of Bayer Materials Technology Implementation Committee and global head of sustainable development, explained: "We are always committed to creating materials and solutions that can continue to develop. Through the simple design that makes the finishing point, we can achieve a simple and beautiful artistic effect. Therefore, sometimes it is not necessary to reproduce the effect of the product with a large area of printed graphics and text, which can also save printing costs and reduce costs. For example, we choose brightly colored art paper and match it with appropriate ink according to the characteristics of the product, so that the ink color and paper color form a strong relationship To attract customers' attention. Of course, you can also choose some art paper with high transparency, and use its translucency to make reasonable design, so that the artistic sense of the product can be strengthened

2. Understand the thread property of art paper, and consider the stiffness required for the outer packaging of the product

effective use of the characteristics of art paper with good strength, toughness, stiffness and elasticity can increase the appearance stiffness of packaging products and improve the grade of products. In the design of cartons, it is often necessary to mount ordinary paper and art paper. At this time, we should pay attention to the thread direction of the paper. The usual practice is to make the thread directions of the lined plain paper and art paper perpendicular to each other to increase the stiffness of the carton

3. Use special post press processing technology

mainly use embossing, UV polishing, hot stamping and other processes. Due to the high content of long fiber in the art paper, it has good stiffness and toughness, and is usually thick. It is suitable for embossing to improve the artistic effect and grade of the product. Many art papers have rich textures and special textures, which can be used to make a sharp contrast with the gloss produced by UV glazing, so as to achieve special artistic effects

4. Selection of printing method

if the product is required to have bright color and thick ink layer, silk printing should be considered. But if you want to get a clear feeling, you should consider using offset printing. The choice of printing method will have an important impact on the final effect of the product

5. Selection of printing ink

in order to pursue gorgeous appearance, many customers will consider using silver ink and gold ink for printing. However, in the design process, the layout should be designed reasonably according to the characteristics of art paper and printing process. It is necessary to be beautiful and generous, and fully consider the characteristics of gold and silver ink and printing process requirements, so as to avoid unexpected printing failures as far as possible. Generally speaking, gold and silver inks are mainly used on the field parts or color blocks if necessary, and it is better not to design gold or silver for very small Yin, Yang and level transitions. In the process of plate making design, the color sequence of gold and silver ink should be considered to ensure the metal color. Also consider the requirements of gold silver ink printing on art paper. If the art paper has a strong absorption of ink, the binder will be absorbed quickly, and the metal pigment in the ink will float on the surface of the art paper, lose its luster, attach loosely, or even fall off. The art paper with strong acidity is easy to react with metal powder, resulting in discoloration and loss of luster of metal pigments. When printing gold and silver ink on art paper, it is usually necessary to lay the bottom color ink first. For example, when printing silver ink, lay a layer of light white ink first. This can not only improve the gloss of the silver ink layer, but also strengthen the adhesion of the silver ink on the paper. After printing gold and silver ink, some products should also consider UV glazing or water-based glazing, or film coating, to prevent oxidation discoloration or falling off of metal pigments
