Commonly used types of printing paper

1. Ordinary printing paper: The specification of paper refers to that after the paper is made, it is cut to a certain size. China has adopted international standards, and it is stipulated that A0, A 1, A2, B 1, B2, A4, A5 and other marks should be used to express the paper format specifications.

Printing paper is classified according to paper thickness, such as 60g, 70g, 75g, 80g, 85g, 90g, 100g, 120g, etc. That is to say, the weight per unit area of paper is a multiple of the square, because the density of paper is basically the same, and the heavier the weight per unit area, the thicker the paper.

2. Carbonless printing paper: also known as pressure-sensitive printing paper, it can only be printed on a stylus printer. 24 1 stands for 9.5 inches, which is the width of the paper. This kind of paper is also called 80-column printing paper (width 9.5 inches * height 1 1 inch).

The main uses of these bills are: delivery/receipt documents, financial statements, ocean air bills of lading, house bills, consumption bills, bank bills, and the main applications are: government departments, enterprises, banks, hospitals, express delivery companies, supermarkets, hotels, KTV, clinics, docks, air transportation, sea transportation, etc.

3. Newsprint: commonly known as white newspaper, it is characterized by soft and porous, certain institutional strength and good absorption, which can make the ink penetrate and fix in a short time and will not stick when folded. It is used to print newspapers, periodicals and general books on high-speed rotating machines. The basis weight of newsprint is 5 1g/m2, and the width of rolled newsprint is 1572mm, 1562mm, 787mm and 781mm.. The size of the planographic paper is 787mm * 1092mm.

Newsprint is suitable for printing and opaque, but its whiteness is low and its surface smoothness is different. When printing pictures, use a thick screen, which is easy to turn yellow and brittle after sunlight, and should not be stored for a long time.

4. paperboard: also known as coated paper, it is a high-grade printing paper made by coating a layer of white paint made of calcium carbonate or white clay and adhesive on the base paper, drying and calendering. Because of its fineness and whiteness, high smoothness, good gloss and moderate oil absorption, it is suitable for copper plate printing or offset printing, printing color or monochrome pictorial, pictures, calendars, maps and books, and also packaging and printing paper.

It is divided into single-sided coating and double-sided coating, and the two kinds are divided into special number, 1 No.,No.2 and No.3, and the quantitative is 80 g/m2 to 250 g/m2. Coated paper requires high coating strength, no powder loss, and can be suitable for fine screen printing above 60 lines /cm.

5. Kraft paper: tough and waterproof wrapping paper, brown and widely used. It is often used to make paper bags, envelopes, record covers, documents and sandpaper. The quantitative range is 40 g/m2 to 120 g/m2, and there are differences between roll paper and plain paper, single side, double side and stripes. The main quality requirements are flexibility and firmness, high bursting resistance, and being able to withstand large tensile force and pressure without cracking.

Selection of carbonless printing paper

After unpacking, it should be noted that if it is not used for a long time, it should be put into the original plastic bag to prevent moisture damage. If it is carbon-free copy paper, be careful not to be squeezed by sharp objects or external forces, so as not to cause color development and affect the use.

Before using the product, you should confirm the gear of the printer. When multi-layer printing, high-speed printing is not needed as far as possible to ensure the readability of printed handwriting. When saving documents, we should pay attention that each copy should be saved separately. If they must be stored together, avoid squeezing. Avoid light, water, oil, acid and alkali.

Carbonless printing paper can be stored for at least 15 years as long as it is in a suitable environment. If there is a paper jam during printing, please check whether the position of the printing paper is appropriate, whether it is aligned with the tractor, and whether the print head has selected a position suitable for the number of paper layers.
