What types of copy paper are there_What does copy paper include?

The types of copy paper can be divided into: coated paper, cardboard, board paper, corrugated paper, etc.

Coated paper is also called printing coated paper. This kind of paper is coated on the base paper. A layer of white slurry, made by calendering. The paper has a smooth surface, high whiteness, small stretchability, and very good ink absorption and reception. It is mainly used for printing covers and illustrations of high-end books and periodicals, color pictures, various exquisite product advertisements, samples, product packaging boxes, trademarks, etc. Matt coated paper is less reflective than coated paper. Although the patterns printed with it are not as colorful as coated paper, the patterns are more delicate and high-end than coated paper. The printed graphics and pictures have a three-dimensional effect, so this coated paper can be widely used to print pictorials, advertisements, landscape paintings, exquisite wall calendars, portrait photos, etc.

Cardboard is an ideal material for making high-end packaging boxes. Its good feel, ideal color and dot transfer conditions, as well as stiffness and surface strength are all reasons chosen by designers. According to the requirements of different packaging boxes, designers can make design choices for various cardboards. (1) White cardboard The characteristics of white cardboard are that it not only has high whiteness, but also has a soft luster, is elegant and noble, has good dot transfer during printing, can achieve a very high level of gradation and color restoration, and has a delicate hand feel. Designers often use white cardboard in high-end products such as gift boxes, cosmetic boxes, wine boxes, and hang tags. (2) Glass cardboard Glass cardboard is a kind of cardboard produced by vitrifying the surface of white cardboard. The surface gloss of this paper is very high and it feels smooth. Its visual effect is better than cardboard and coated paper. The gloss after UV glazing is still high, and the products made with this cardboard are very bright and eye-catching. Designers often use glass cardboard in packaging boxes for pharmaceuticals and high-end cosmetics.

Board paper is a kind of paper with a laminated structure. Its basis weights are 220g/m2, 240g/m2, 250g/m2, 400g/m2, 450g/m2. The range is very wide, and there is room for selection of various materials. The largest among them. This kind of paper has a certain degree of stiffness and surface strength. In particular, colored whiteboard paper has a surface coating that prevents printing ink from penetrating easily. It uses less paper and has good color and dot transfer of printed images. But the disadvantage is that the flatness is poor and the printing speed is slow; another disadvantage is that the hand feel is obviously rough compared with cardboard.

The most commonly used corrugated cardboard is corrugated cardboard. The color of corrugated cardboard itself is quite dark, so when choosing printing colors, you must consider using inks with high color saturation and strong tinting power (such as large red), otherwise the printed color will be very different from the desired color. Ink viscosity is the main indicator that needs to be controlled in corrugated cardboard printing. It is one of the main factors affecting the printing color condition. Corrugated cardboard is used in display racks in various industries such as food, clothing, sporting goods, IT products, daily necessities, automotive supplies, music, and books. In order to cater to the diversity of paper display stands and make them more popular among consumers, they are often used together with other materials, so that the made paper display stands can carry more shapes and be more novel.
