Art Paper Classification With the development of the packaging and printing industry, the demand for specialty papers in the domestic market is increasing. Specialty paper has become one of the most important products in paper products. Its variety has become more and more numerous, and the scope of application has also been expanding. In order to give readers a slight understanding of this species, the following describes in particular the relevant characteristics of some specialty papers and their relationship with printing design. Since the invention of papermaking, paper has been used as a material with cultural properties. Its scope of application has been continuously expanding, and it has also been given more connotations. As for the classification of papers, the art papers (also known as fancy papers and specialty papers) mentioned here mainly refer to cultures and packaging papers that are different from ordinary printing papers, such as coated paper, offset paper and newsprint. This type of paper usually requires special paper processing equipment and processes. The processed paper is rich in color and unique lines. Art paper can be applied to exquisite book covers, albums, brochures, invitations, greeting cards, high-end office papers, business cards, and high-grade packaging paper. At present, with the rapid development of the domestic economy, people’s aesthetic requirements are constantly increasing. The demand for displaying images and communicating information through paper is increasing. The art paper industry has also been rapidly developed. Since entering China in the early 1990s, art paper With its unique charm, it attracted many people in the design and printing industry. The use of art paper has also increased dramatically. The number of people engaged in the sale of art paper is also increasing rapidly. Take Singapore's Xiemao Paper Co., Ltd. as an example. It entered China at the end of 1993 and has since grown from a company in the country to a large art paper sales company with four wholly-owned companies and nearly 30 distributors and liaison agencies. First, the classification of different angles 1. Look from the pulp. The quality of specialty paper pulps is relatively high. Most of them are pure wood pulps with long fibers and some contain cotton. This paper pulp has good strength and toughness after papermaking. The paper has good stiffness and elasticity, and the color is also bright. Pulp of plain paper is provided with a certain proportion of non-wood fibers, and the paper tends to turn yellow and generally needs to be coated. 2. From the dyeing point of view can be divided into pulp dyeing and post-dyeing: Pulp dyeing is the addition of toner in the papermaking pulp, so that the color is evenly distributed in the paper fiber, the paper is saturated in color and uniform in cross-section. After dyeing, after the paper is formed, the pigment is dyed on the surface of the paper with the infiltration method, the color stability is inferior to the pulp dyeing, and the water is prone to discoloration. When the dark paper is folded, white edges are easily formed and the overall effect is destroyed. 3. From embossing mode, it can be divided into front embossing and post embossing. The former embossing means that soft felt is felt when the pulp is not fully dehydrated, so that the paper fibers are distributed according to the natural texture of the felt to form a special texture of the paper. The pre-embossed paper texture transitions naturally and delicately without damaging the paper fibers. After embossing, the finished paper is passed through an engraved steel roll, which uses mechanical pressure to create a pattern on the paper. The advantages of post-embossing are the simplicity of the process, the relatively low cost, and the ease of use. However, this process damages the paper fibers, so the quality of the base paper directly affects the quality of the finished paper after embossing. The pattern of embossing patterns after the change is less, and the embossed pattern before the comparison is slightly mechanical and rigid. $Page break $ Most of the art paper is imported, and it is basically based on the price of Zhang, which is more expensive than ordinary printing paper. Therefore, in addition to having a certain understanding of its use in prepress, printing, and postpress, it should also deal with the following: Take note of several aspects. 1. Understand the full paper size Art paper is usually not a generous and positive specification, and different art papers have different specifications and should be specified when ordering. Careful consideration and measurement should be made when calculating the opening number or size, and the paper area should be used as effectively as possible. In order to reduce the cost, it may be considered to open up (mixed open) or break open, so as to avoid unnecessary waste. 2. Identify the front and back Art paper is mostly used for single-sided printing, and it is necessary to distinguish between its front and back sides. Some art papers are easy to distinguish on the obverse side, but some are very similar on both sides, so it is necessary to mark the outer packing when feeding paper, so as to avoid misidentification of the front and back due to misdirection. . 3. Understand inventory The inventory here refers to the amount of domestic stock, which is the number of papers that can be accessed directly. The date and place of the paper must be clearly stated when making the paper, and if necessary, the paper can be further checked for smooth inspection. 4 clear pattern Many art papers look very similar, but there are great differences in printability. Therefore, when the customer brings a sample of paper, be sure to ask as many information as possible about the agent, number, and grammage of the paper in order to make paper. Otherwise, it is very likely that you will not find such papers for a few days or nights, which will affect the progress of printing. 5. Keep it properly The price of art paper is high, and proper preservation is especially important. Under normal circumstances, it is necessary to control the temperature and humidity in the workshop throughout the year to avoid paper deformation. And to ensure the integrity of the art paper packaging, as soon as possible before opening the seal before opening. The characteristics of art paper itself determine that in the field of packaging and printing, it is not the value of the reproduction of the product mainly based on graphic arts, but the full use of the unique color and texture of the art paper, and then appropriate design. The unique glossiness and color difference of art paper will bring people different feelings. When these different paper personalities are combined with the design, they need the designer's ingenuity to use the individuality of the art paper to convey the design intent, so that the individuality of the paper becomes a part of the design, and it is perfectly integrated with the design style, so as to show a unique artistic effect. . In the prepress design, the following points should be noted. 1 according to the characteristics of the product to choose 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, selecting colorful art papers and matching the inks according to the characteristics of the products will create a strong contrast between ink color and paper color so as to attract customers' attention. Of course, some art papers with higher transparency can also be selected to make use of their translucency and to be rationally designed to enhance the artistic sense of the product. 2. Understand the silkiness of art paper, and consider the stiffness required for product packaging The effective use of art paper has the characteristics of good strength, flexibility, stiffness and elasticity, which can increase the appearance stiffness of packaged products and improve the grade of the products. In the design of the carton, it is often necessary to confront plain paper and art paper, and at this time, pay attention to the orientation 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 a special post-printing process Mainly used embossing, UV glazing, hot stamping and other processes. Due to the long fiber content in art paper, it has good stiffness and toughness, and is usually thicker 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 texture. This feature can be used to make it in sharp contrast with the gloss produced by UV glazing in order to achieve special artistic effects. 4. Choice of printing methods 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. Selection of printing ink Many customers would like to use silver ink and gold ink in order to pursue a gorgeous appearance. However, in the design process, according to the characteristics of art paper and the printing process, a reasonable layout should be designed so as to not only be beautiful, but also fully consider the gold, Silver ink features and printing process requirements, try to avoid printing failures that should not occur. In general, gold and silver inks are mainly used in the field parts or color blocks, and it is better not to design them as gold or silver for very small intaglio texts, yang texts, and hierarchical transitions. 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 ink on art paper is very strong, the linking material will be quickly absorbed, and the metal pigment in the ink will float on the surface of art paper, lose its luster, become weakly attached, 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 coating or water-based coating, or laminating to prevent the metal pigments from discoloring or falling off. The uniqueness of the papermaking process has made the art paper a lot of specialties in the structure and performance of the paper, resulting in many special aspects of the printing process. 1. Ink absorption All kinds of art papers have a great absorption of ink, such as: coaster paper is easy to absorb ink, Leniy paper is easier to absorb ink, and transparent paper is difficult to absorb ink. The ink absorption of the used art paper is directly related to the quality of the printed product and the required delivery time. For papers with poor ink absorbency, driers can be properly added to the ink or cured by UV light to prevent the back of the ink from drying too slowly and causing the back of the dirty, imprinted powder and other phenomena. Of course, the structure of the paper has a great influence on ink absorption. Some papers have a loose texture and the ink can easily penetrate and dry; while others have a very tight texture and the ink floats on the surface of the paper, so that it is not easily penetrated into the paper and is less likely to dry. Art papers with different ink absorption properties can usually be controlled by adjusting the printing pressure and processing the ink. If necessary, a certain amount of test printing can be performed first (the quantity is determined according to needs). 2. Smoothness Due to different papermaking processes, some art papers are relatively bulky and have low smoothness; some papers are denser and have higher smoothness. In art paper, there are also papers with embossed effects (such as embossed paper) and stripe-like textures (such as bamboo paper). When encountering this type of paper, it is generally recommended to print less or even not to print, and to use paper's natural embossing to perform some simple local processing such as embossing, UV varnishing, hot stamping, etc., thereby basically retaining the original paper's characteristics. And make full use of these qualities to achieve the desired decorative effect. Of course, if it is necessary to print, it is very necessary to regulate the printing pressure so that specific problems can be analyzed. Such as the printing of thicker art paper, the printing pressure should not be too large, otherwise it will undermine the characteristics of this type of art paper shading obvious, and make the paper deformation. On the other hand, if it is an art paper with a more closely printed texture, the pressure on printing should be appropriately increased. Special paper printing and decorating effect With the improvement of people's living standards, there are more and more varieties of paper, and special paper comes into being. It is widely used in various graphic designs, especially the design of high-grade pictures and book covers.
