What are the specific requirements for special paper printing design of Chocolate Drawer Box?
When printing on special paper, because this kind of work belongs to special printing, there are certain requirements for printing design. Here is a detailed introduction to the printing design requirements of several types of paper.
1. Embossed paper
(1) Features of embossed paper
Adopt the method of mechanical embossing or crepe paper to form a concave and convex pattern on the surface of the paper or cardboard. Embossed paper improves its decorative effect by embossing, making the paper more textured. In recent years, the embossing of the surface of printing paper has become more and more extensive. Color dyed paper such as offset paper, coated paper, sword board paper, and sword cardboard is embossed (pattern) before printing, as "embossed printing paper" , can greatly improve the grade of paper, and also bring higher added value to the sale of paper. Many papers used for flexible packaging are often embossed before or after printing to improve the visual effect of the packaging table and improve the value of the product. Therefore, embossing has become a main way of paper processing.
(2) Processing method of embossed paper
There are two ways to process embossed paper. One is that after the paper is produced, the pattern is added mechanically to become embossed paper; the other is that after the flat base paper is dry, it is put into the embossing machine for further processing, and then pressed by two rollers, one of which is rolled. The shaft is engraved with an embossed pattern, which is embossed after the paper is passed. Because the texture of embossed paper is deeper, only one side of the paper is usually embossed.
(3) Types of embossing
Embossing can be divided into two types: set embossing and non-set embossing. The so-called overprint embossing is to press the printed flower shape into a concave and convex shape according to the printed flower shape, so that the pattern is raised, which can play the role of elegant decoration.
There are many kinds of embossing patterns without register embossing, that is, the embossed patterns are not directly related to the pattern of the printing. Such as cloth pattern, twill pattern, straight stripe, Yalian mesh, orange peel pattern, straight mesh pattern, needle mesh pattern, egg skin pattern, sack pattern, plaid pattern, leather pattern, scalp pattern, summer cloth pattern, gear stripe, etc. This non-overprint embossing is commonly used for embossing printing paper, coated book paper, patent paper, plastic synthetic paper, vegetable parchment and other decorative materials.
The domestic embossed paper is mostly made of offset paper and sword board paper. The outline is relatively crude, textured, expressive, and has a wide variety. Many art designers prefer to use this kind of paper, and use it to make the cover, title page, etc. of books or albums to express different personalities.
2. Vegetable parchment (sulfuric acid paper)
Plant parchment is a kind of denatured processed paper that converts the original properties of thick paper made of plant fibers after being treated with sulfuric acid. It is translucent, with few air bulging holes in the paper, the paper is tough and dense, and can be processed by waxing, coating, embossing or wrinkling. Its appearance is very easy to mix with tracing paper.
Because it is a translucent paper, sulfuric acid paper is often used as a ring lining or backing paper for books in modern design, so that it can better raise and set off the theme, and is suitable for modern trends. Sometimes it is also used as the title page of a book or picture album.
3. Synthetic paper (polymer paper and plastic paper)
Synthetic paper is made of synthetic resin (such as PP, PE, PS, etc.) as an important raw material. After a certain process, the resin is melted, extruded and extended into a film, and then processed into paper to give it the natural plant fiber. Data obtained for sharpness, opacity, and printability. Generally, synthetic paper is divided into two categories: one is fiber synthetic paper, and the other is film-based synthetic paper.
The appearance of synthetic paper is no different from general natural plant fiber paper. Film-based synthetic paper has entered the market of high-grade printing paper and can adapt to various printing machines. The synthetic paper used in the market at the moment only refers to the film-based synthetic paper. If the books, advertisements, imitations, etc. printed on synthetic paper are not marked, the general consumer will not see any difference between them and ordinary paper.
Synthetic paper has excellent printing performance, and there will be no "paper break" phenomenon during printing; the surface of synthetic paper has very small unevenness, which is very helpful for improving opacity and printability; synthetic paper image reproduction is good , The dots are clear, the tone is soft, the ruler is micro-fleck and stable, and it is not easy to age. It is worth noting that when using offset printing, professional synthetic paper offset printing inks should be used.
Specialty paper is a paper with special utility and relatively small output. There are many kinds of special paper, which is the collective name of all kinds of special-purpose paper or art paper. At present, sellers collectively refer to embossed paper and other art paper as special paper, mainly to simplify the confusion of nouns caused by the wide variety. There are many kinds of special paper, and the design results are not the same. This article briefly introduces the precautions of art paper printing design.
