Art Paper Printing Precautions (I)

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 specialty papers have emerged. They are widely used in various graphic designs, especially the design of high-end albums and book covers, and are deeply loved by the general public. The special paper has the advantages of compressibility, foldability, and convenience of processing and easy molding. It is not achieved by other packaging materials, and it is also a great advantage as a paper printing material.

Paper texture

There are many types of specialty papers, and there are also great differences in the expressiveness of print design. Designers must understand and master the characteristics and performance of different specialty papers in order to make better use of their advantages and design a variety of different styles such as simple and elegant, luxurious and festive, modern and simple.

Specialty paper has a certain strength, light weight, surface bumps, textures, smoothness, gloss and other different types, its color is diverse, beautiful appearance. In particular, paper materials manufactured and processed from plant fibers are environmentally friendly and recyclable. They are the preferred materials for green packaging.

Texture

Texture is the skin of an object and it is also a modeling factor related to any object. The roughness or smoothness of the surface of the object belongs to the texture. It must be perceived through sight and touch. Texture does not refer to form nor color, it is a modeling factor that requires special feelings.

Texture can be divided into two categories: one is the tactile texture that can be touched by the hand, and the other is the visual texture that can be felt through the visual sense.

(1) Tactile texture

The tactile texture is extremely straightforward, as long as it is touched, the blind person can feel it, but after being photographed, he loses the directness of touching the cognitive texture.

In recent years, paper and other packaging materials have used a variety of special paper materials with different textures, such as embossed paper and paper, to make people feel the tactility of the surface. There are obvious differences in touch texture on the surface of offset paper, coated paper, and special paper, and thus their artistic expression is also different.

(2) Visual texture

We watch TV every day. The television tube is made of glass and is smooth. But the texture that people feel on the screen in television is the visual texture caused by the visual sensation and not the real sense of texture.

Paper is a flat material, and you can feel the visual texture of the material through graphics. For example, stripes and patterns are designed using people's visual texture.
