The selection and use of materials is one of the important links of packaging design, which is directly related to the quality and effect of product packaging. Reasonable selection of paper materials, and master the use of skills, can improve the visual appeal of packaging, protection performance and user experience. This paper will discuss the selection and use of lift-up flaps book materials from the aspects of paper material selection, paper characteristics, printing technology and so on.

First, paper material selection

Wear resistance: The wrapping paper material needs to have a certain amount of wear resistance, which can protect the product from damage during transportation and use. Common paper materials with good wear resistance include kraft paper and corrugated paper.

Strength and hardness: The strength and hardness of the packaging material determine the carrying capacity and compressive capacity of the packaging. For products with large load-bearing capacity, thicker and stronger paper materials, such as corrugated cardboard, should be selected.

Paper color: The color of the paper directly affects the printing effect and product image. In general, white paper is suitable for most products and can show the bright color of the product. In addition, you can also choose a special color paper that is coordinated with the product to enhance the uniqueness of the product.

Surface treatment: The surface treatment of the wrapping paper material can improve the hardness, gloss and anti-pollution properties of the paper. Common surface treatment methods include coating, laminating and hot stamping. According to the needs of the product, choosing the appropriate surface treatment can improve the texture and quality of the packaging.

Environmental protection: In the process of paper material selection, the environmental protection of paper needs to be considered. Choosing renewable and degradable paper materials that meet environmental standards can reduce the negative impact on the environment and enhance the brand image.

Second, paper characteristics

Paper gloss: The gloss of the paper determines the appearance of the printed matter, which is divided into high gloss paper, matte paper and matt paper. Highlighter paper is usually used to print color pictures and can show bright colors; Matte paper is suitable for printing text and patterns, which can increase the comfort of reading; Matte paper is often used to print black and white patterns and text, which can provide a better reading experience.

Ink absorption of paper: The ink absorption of paper affects the printing effect of printed matter. Choosing a paper with good ink absorption can enhance the saturation and clarity of the color and improve the printing effect.

Paper thickness: The thickness of the paper determines the strength and carrying capacity of the package. Choose the right paper thickness according to the weight and size of the product to ensure the stability and protection of the packaging.

Paper moisture content: The moisture content of paper has a great impact on the quality and stability of printed matter. Paper moisture content is too high or too low will cause the print deformation, wrinkles or discoloration. In the printing process, the appropriate moisture content of the paper should be maintained to obtain good printing results.

Three, printing technology

Printing method: Select the appropriate printing method according to the packaging design and printing needs, such as offset printing, letterpress printing, screen printing, etc. Offset printing is often used to print large areas of flat patterns and text; Letterpress is suitable for printing three-dimensional patterns and text; Screen printing can be printed on surfaces of various materials.

Printing color: According to the requirements of the product and design style, choose the appropriate printing color. Common printing colors are monochrome, two-color and full-color. Monochrome for black and white printing and simple design; Two colors are suitable for colorful designs; Full color can show more layers of color, suitable for the need to highly restore the true color design.

Post-printing treatment: Post-printing treatment can increase the texture and quality of the package. The common post-printing treatment methods are hot stamping, embossing, glue and so on. Through the rational use of these techniques, the packaging can be made more unique and attractive.
