Analysis of the printing characteristics and design points of common printing paper

I. printing adaptability and design points of coated paper

due to the good printing adaptability and physical performance of coated paper, designers can boldly use high-precision lines to express images. Coated paper is often used for trademark printing of advanced samples, posters, book covers, and various commodities (such as labels on cans, beverage bottles, wine bottles, etc.); It is also commonly used in the packaging of high-grade candy, food, chocolate, cigarettes, soap and other supplies; It can also be used for the veneer of various high-grade cartons and cartons. However, coated paper with relatively low quantity should be selected, which generally does not exceed 105g/m2

coated paper is divided into glossy coated paper and matte coated paper (also known as matte coated paper). Attention should be paid to when designing: glossy coated paper is more suitable for displaying images that require bright colors and brightness; However, matte has put forward higher and higher requirements for material mechanical property testing instruments. Due to its soft luster, coated paper is more suitable for samples that show elegance or feel heavy

II. Printability and design points of light-weight coated paper

use light coated paper as printing paper, and pay attention to bright and bright color blocks as much as possible in design, rather than large-area color blocks with low lightness. For example, magenta and cyan are large-area blue on the ground, and it is not suitable to have other colors on this color block

light coated paper is generally not suitable for post press processing due to its low weight, thin paper and poor stiffness. Attention should also be paid to avoid printing gold, silver and pearlescent inks

III. printability and design points of self-adhesive paper

self adhesive paper is composed of surface substrate, adhesive and base paper. The types of paper surface base materials are divided into offset paper; art paper; Glass paperboard; Foil paper

self adhesive paper is selected as the substrate, and its visual characteristics can be selected according to the substrate on the paper surface. Offset paper is generally used for printing words or simple color blocks, which is cheap. Coated paper or glass paperboard adhesive can be used for high-end color printing, especially glass paperboard adhesive has mirror visual effect, excellent smoothness and gloss

if you need special effects, you can choose foil film adhesive. This kind of self-adhesive is coated with thin aluminum foil on paper with high smoothness, which has gold and silver. From the perspective of gloss, there are two kinds of light, whether light or not

IV. printability and design points of offset paper

offset paper can be divided into high-grade and medium-grade

when designing high-grade offset paper, it can be applied to color images with rich printing levels, and the ink volume can also be relatively large

when used in high-end envelopes and stationery, offset paper is a little stronger than coated paper, that is, the hand feel of writing is obviously better than coated paper, and the ink is easy to dry

medium grade offset paper is a good choice for printing the text of books and periodicals, especially for printing the instructions of some household appliances. Because the text is mainly text, using offset paper is obviously more atmospheric than writing paper

v. printability and design points of kraft paper

kraft paper is a high-grade packaging paper, which is widely used. It is mostly used for packaging industrial products, such as cotton, wool, silk fabrics, wool, hardware and electrical products, instruments and meters. It can also be used for processing sandpaper, archival paper, files, paper bags, envelopes, etc. It can also be used for hanging noodles and hanging inside cardboard

kraft paper can be divided into single-sided light, double-sided light, striped and non striped in appearance. Generally, kraft paper is yellowish brown, but there are also colored kraft paper and white kraft paper

VI. printability and design points of whiteboard

whiteboard is mainly used as an important material for sales packaging. Because the cardboard is thick and has a certain buffer, it has a certain protective effect on commodity packaging. High grade whiteboard can achieve the same effect as coated paper after color printing. It is often used to package daily necessities such as food, medicine, cosmetics, toys, household appliances and so on, playing the role of beautification and publicity. It can also be used as hang tag, lining board of commodities and bottom support of blister packaging

whiteboard is also often used by designers to make composite containers with aluminum foil and plastic instead of metal containers and glass containers. Peek sales climbed 6% to 679 tons of materials, food, milk, etc. compared with the same period last year

whiteboard is selected as the commodity packaging material in the design. It should be noted that there is a certain gap between the smoothness and surface smoothness of whiteboard and high-grade coated paper, and the point accuracy of the image should not be too high, so as to avoid poor point transfer and layer loss. Compared with high-grade paperboard, whiteboard is relatively rough. Therefore, whiteboard is generally not suitable for high-grade commodities with small specifications and sizes, especially for high-grade drugs and cosmetics. Instead, homogeneous paperboard should be selected to improve the grade of products

VII. Printability and design points of paperboard

paperboard can be routinely divided into white paperboard and beige paperboard according to the paper color

although the gloss of white cardboard is not as good as that of coated paper, the color picture on high-grade white cardboard is soft, elegant and noble

in printing design, white card paper is often used to print business cards, certificates, invitations, covers and postcards

in printing design, Micah paper is often used to print advanced menus, promotional pictures, or as the back liner of the cover of precision books and periodicals

VIII. Printability and design points of corrugated paperboard

there are two ways to print corrugated paperboard, one is to paste the printing paper on the prepared paperboard, and the other is to print directly on the corrugated paperboard

flexible printing, silk printing and other methods are commonly used for plastic film printing of corrugated board, mainly flexible printing

IX. the printability and design points of synthetic paper continue to develop and expand

synthetic paper, also known as polymer paper and plastic paper, is a material obtained by taking synthetic resin as the main raw material, melting, extruding and extending the resin into a film through a certain process, and then carrying out papering treatment, giving it the whiteness, opacity and printability of natural plant fiber paper. Now the synthetic paper in the market only refers to the film as synthetic paper

synthetic paper has the following characteristics:

① high strength

② excellent printing performance

③ stable size, not easy to aging

④ light weight, water resistance, outstanding chemical resistance

⑤ insect resistance and safety

special attention should be paid to when designing and selecting synthetic paper:

① although the folding resistance of synthetic paper is better than ordinary paper, once folded, there will be crease lines that are difficult to disappear, which will damage the beauty of printed products. Therefore, pay attention to the size when printing, not too large

② it is difficult to recycle synthetic paper after use, which will cause environmental pollution

③ the cost of synthetic paper is higher than that of ordinary paper

X. printability and design points of composite paperboard

composite paperboard is generally composed of paperboard and composite layer. Ordinary white cardboard is used

when designing and selecting composite paperboard, the following problems should be paid attention to:

① when designing the bottom color, the bottom color should not be covered completely, and the metal bottom color should be exposed more

② if there is a four-color overprint dot image, it should be designed as a small area. It is not suitable to use large-area four-color overprint

③ the color block printing should be designed as spot color printing as much as possible, because the drying of large-area stacked color blocks is slow

④ when printing, small areas of color blocks, words, lines, light colors are printed first, and large areas of color are printed later

⑤ there are four-color continuous tone images, which should be primed first, and the covering power of inks should be high. (end)
