Performance difference between coated paper and composite paper
Printing suitability and design points of white paper
1. White paper is mainly selected as an important material for sales packaging. Because the cardboard is thick and has a certain cushioning property, it has a certain protective effect on commodity packaging. High-grade white paper can achieve similar effects to coated paper by color printing. It is often used for packaging food, pharmaceuticals, cosmetics, toys, household appliances and other daily necessities, and plays a role of beautification and publicity. It can also be used as a product's tag, liner, and base for blister packaging.
White paper is also often used by designers to make composite containers with aluminum foil and plastic, instead of metal and glass containers, packaging materials, food, milk, etc.
White paper is used as the packaging material for the design. Pay attention to the difference between the smoothness and surface smoothness of white paper and high-grade coated paper. The dot accuracy of the image should not be too high, so as not to cause poor dot transfer and layer loss. White paper is rougher than high-level paperboard. Therefore, it is generally inappropriate to use whiteboard paper for high-end products with relatively small specifications, especially for high-end pharmaceuticals and cosmetics. Whiteboard paper should not be used for product packaging. To improve the quality of the product.
2. Printing suitability and design points of cardboard
According to the color of the paper surface, the paper jam can be conventionally divided into two types: white paper jam and beige paper jam.
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 and elegant.
In printing design, white cardboard is often used to print business cards, certificates, invitations, covers, and postcards.
When printing design, Mika paper is often used for printing advanced menus, posters, or as a backing paper for the cover of precision books and periodicals.
3. Printing suitability and design points of corrugated cardboard
There are two ways to print corrugated paperboards, one is to print the face paper on the finished paperboard, and the other is to print directly on the corrugated paperboard.
The printing of corrugated cardboard is usually flexographic printing, silk screen printing and other methods, mainly flexographic printing.
4. Printing suitability and design points of synthetic paper
Synthetic paper, also known as polymer paper and plastic paper, uses synthetic resin as the main raw material. After a certain process, the resin is melted, extruded, and stretched to form a film, and then paperized to give whiteness to its natural plant fiber fiber paper , Opacity and printability. The synthetic paper on the market now refers only to film-based synthetic paper.
Synthetic paper has the following characteristics:
① High intensity
②Excellent printing performance
③Stable size, not easy to age
④ Lightweight, water and chemical resistance
⑤ Has insect resistance and safety
Pay special attention when designing and selecting synthetic paper:
①Although the synthetic paper is more resistant to folding than ordinary paper, once folded, there are fold lines that are difficult to disappear, which impairs the aesthetics of the printed matter. Therefore, pay attention to the size when printing, it should not be 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 ordinary paper
5. Printing suitability and design points of composite cardboard
Composite paperboard generally consists of paperboard and composite layers. The cardboard uses ordinary white cardboard.
When designing and selecting composite cardboard, the following issues should be noted:
① When designing the background color, the background color should not be completely covered, and the metal background color should be more exposed.
② If there are four-color overprint halftone dot images, they should be designed to have a small area. It is not advisable to use a large area of ??four-color overprint.
③ Try to design spot color printing for color block printing, because large-area stacked color blocks dry slowly.
④ When printing, small areas of color blocks, text, lines, light colors are printed first, and large areas of color are printed after.
⑤ There are four-color color continuous tone image, you need to make a base first, and the covering power of ink should be high.
