1. the printing suitability and design points of coated paper
Due to the good printability and physical properties of coated paper, designers can boldly use high-precision network cables to represent images. Coated paper is often used for advanced samples, posters, book covers, trademark printing of various commodities (such as cans, beverage bottles, wine bottles, etc.); also used in high-grade candy, food, chocolate, cigarettes, soap and other supplies. Packaging; can also be used for a variety of high-grade carton, carton veneer. However, a relatively low-quantity coated paper should be used, generally not exceeding 105 g/m2.
Coated paper is divided into two types: optical copper plate and matt coated paper (also known as matt coated paper). Attention should be paid to the design: the glossy coated paper is more suitable for the image that requires bright and bright colors; and the matte coated paper is more suitable for the samples with noble elegance or heavy weight due to the soft gloss.
2. the printing suitability and design points of lightweight coated paper
Use light-coated paper as the printing paper. When designing, pay attention to using bright and bright color blocks as much as possible, and not design large color blocks with low brightness. For example, magenta and cyan are large areas of blue on the ground, and it is even more inappropriate to have other colors on this color block.
Lightly coated paper is generally not suitable for some post-press processing because of its low basis weight, thin paper, and poor stiffness. Attention should also be paid to avoid printing gold, silver and pearlescent inks.
3. the printability and design points of self-adhesive paper
Self-adhesive paper consists of three parts: surface substrate, adhesive and base paper. The types of paper surface substrates are classified into offset paper; coated paper; glass cardboard; foil paper.
The self-adhesive paper is selected as the substrate, and the visual characteristics can be selected according to the substrate of the paper surface. Offset paper is generally used for printing text or simple color blocks and is inexpensive. Coated paper or glass cardboard stickers can be used for high-grade color printing, especially glass paper stickers have a mirror visual effect, and the smoothness and gloss are excellent.
A special effect is required for the optional foil film adhesive. This kind of self-adhesive is a thin aluminum foil covered on a smooth paper, with gold and silver, and there are two kinds of light and light.
4. the printing suitability and design points of offset paper
Offset paper has high-end and mid-range points.
When designing high-grade offset paper, it can be applied to color images with rich printing levels, and the amount of ink can be relatively large.
When applied to high-grade envelopes and letterheads, offset paper is a bit stronger than coated paper, which means that the hand feel is better than that of coated paper, and the ink is easy to dry.
The medium-grade offset paper is a good choice for printing the text of the book, especially the instructions for printing some home appliances. Since the main text is the text, the offset paper is obviously more atmospheric than the writing paper.
5. Printing suitability and design points of kraft paper
Kraft paper is a high-grade wrapping paper for a wide range of uses. Mostly used in packaging industrial products, such as packaging cotton, wool, silk fabrics, wool, metal power products and instruments, meters and so on. It can also be used to make sandpaper, archival paper, files, paper bags, envelopes, etc. It can also be used for hanging and hanging of cardboard.
Kraft paper is characterized by single-sided light, double-sided light, striped and non-striped. Generally, kraft paper is yellowish brown, but there are also colored kraft paper and white kraft paper.
6. Printing suitability and design points of whiteboard paper
The whiteboard paper is mainly used to sell important materials for packaging. Because the cardboard is thicker and has a certain cushioning property, it has a certain protective effect on the packaging of the commodity. Advanced whiteboard paper can achieve the same effect as coated paper by color printing. It is often used to package food, medicine, cosmetics, toys, home appliances and other daily necessities, and to beautify and publicize. It can also be used as a hangtag for goods, a liner, and a bottom for blister packaging.
Whiteboard paper is also often used by designers to make composite containers made of aluminum foil and plastic, instead of metal containers and glass container packaging materials, food, milk, and the like.
The design uses whiteboard paper as the packaging material of the commodity. It should be noted that the smoothness and surface smoothness of the whiteboard paper have a certain gap compared with the high-grade coated paper. The accuracy of the image dot should not be too high, so as to avoid poor transfer and loss of the dots. Compared with high-grade cardboard, whiteboard paper is relatively rough. Therefore, high-grade products with small size and size are generally not suitable for whiteboard paper. Especially high-grade medicines and cosmetics are not suitable for packaging with white paper, but should use the same type of cardboard. To improve the grade of the product.
7. the paper printability and design points
The paper jam can be divided into white cardboard and beige cardboard according to the color of the paper.
Although the gloss of white cardboard is not as good as that of coated paper, the color of the high-grade white cardboard is soft, elegant and noble.
In the printing design, white cardboard is often used to print business cards, certificates, invitations, covers, postcards.
In the design of printing, Mickey paper is often used to print advanced menus, promotional pictures, or as a cover for precision book covers.
8. the printing suitability and design points of corrugated cardboard
There are two ways to print corrugated cardboard. One type of printed liner paper is printed on the finished board, and the other is printed directly on corrugated board.
Corrugated board printing is commonly used in flexographic printing, screen printing, etc., and is mainly based on flexographic printing.
9. Printing suitability and design points of synthetic paper
Synthetic paper, also known as polymer paper and plastic paper, is made of synthetic resin as the main raw material. After a certain process, the resin is melted, extruded, and stretched into a film, and then subjected to paper treatment to impart whiteness to the natural plant fiber fiber paper. Materials obtained from opacity and printability. Synthetic paper currently on the market refers only to film-based synthetic paper.
Synthetic paper has the following characteristics:
9.1 high intensity
9.2 excellent printing performance
9.3 dimensional stability, not easy to age
9.4 light, water resistant, chemical resistant
9.5 with insect resistance and safety
Pay special attention when designing synthetic paper:
1The synthetic paper has better folding resistance than ordinary paper, but once folded, there will be crease lines that are difficult to disappear, which will damage the appearance of the printed matter. Therefore, pay attention to the size when printing, not too large.
2 Synthetic paper is difficult to recycle after use, which will cause environmental pollution.
3 synthetic paper costs higher than plain paper
10. Printing suitability and design points of composite cardboard
Composite paperboard typically consists of paperboard and composite layers. Cardboard uses plain white cardboard.
When designing composite cardboard, the following issues should be noted:
10.1 When designing the background color, the background color should not be covered, and the metal background should be exposed.
10.2 If there are four-color overprinted dot images, it should be designed to be small. It is not advisable to use a large area of four-color overprinting.
10.3 pairs of color block printing should try to design for spot color printing, because the large area of the color block drying is slower.
10.4 When printing, small areas of color blocks, text, lines, light color first print, large area color after printing.
10.5 There are four color continuous color adjustment images, you must first make a base, and the base should be covered with ink.
