In fact, many people in the hearts of printing paper and copy paper are a very vague concept.In actual use, people do not even distinguish them.The printed paper that is usually said in general refers to a copy paper, that is, A4 printing paper.In fact, there are differences between the two.Below, what is the difference between copying paper and printing paper for you? Can the two be universal? How to choose and use a copy paper correctly?
The difference between copying paper and printing paper
Generally speaking, the boundaries of printing paper and copy paper are not very clear. We call the copy paper through the printed paper because all copy paper can be used for printer printing output.
However, they have differences in the industry. According to the industry methods, printing paper refers to the one with holes on both sides and stacks of stacks. Some can be torn off. We are called tearing edges.Generally used for pinhole printers, for printing bills and the like;
Printing paper specifications: Printing paper is divided according to the number of layers, which can be divided into single layers, two layers, three layers, four layers, and five layers. At present, at most five layers.By divided by size, it can be divided into two types: 241 and 381, 241 is A4, and 381 is A3.If divided by equal parts, you can classify (that is, the entire paper), the second class (a piece of paper is divided into a portion), and the third class (one piece of paper is divided into three copies).
Printing paper use: Printing paper is mainly used for needle printers, used to print the delivery sheet.Copy paper is our common A4 category. Generally, there are three types of 70 grams, 75 grams, and 80 grams. The specifications are divided into A3, A4, B4, B5, 16K, 8K.
Copy paper specifications: According to the size, it can be divided into A4, A3, B5, B4, A5, A6, etc. This is a more commonly used model. Other specifications also have it, but they are not very common. Generally, few people want it.It can be divided into 70g, 80g, and 120g according to weight. If it is thick, it is not a copy paper.
Copy paper purchase parameters: When we buy a copy paper, we mainly refer to the following aspects: thickness, density, tipping, and light. To do this four degrees, we will buy a copy paper that suits us.Everyone uses different places, and the requirements for paper are different. Some of them should be used well, and some are simple and easy to use.The thickness refers to how many grams we usually say, how many grams of, and density, and density refers to the degree of paper dense and thickness.Light refers to the smoothness of the paper surface.
Copy paper use: Copy paper is mainly used for document copying and printing. Like copying ID cards, copying files, it must be used, but also prints Renwu, like printing contracts, quotes.
According to the industry in the industry, printed paper can only be used for needle printers, while other printers or copy paper cannot be used; copying paper canSuitable for various copy paper.
Copy paper choice
Today, the application of paper has expanded to cultural sciences, daily life, medical care, commercial, national defense, and industrial and agricultural production.Office paper is often ignored among all office supplies, but because it is used more and frequently, it is indispensable for our daily office.The most used in office paper is copy paper. Although the copy paper is a dedicated paper, its application range is the widest. It can be widely used in the output of the photocopy, needle printer, laser printer, inkjet printer, etc.The effect requirements are not very high, especially the use on the needle and laser printer is more widely used.The common models of copy paper include: B5, A4, B4, A3 and other models.Copy paper is the most economical paper in various office equipment. For example: a B5 copy paper is 8 packs, 500 pieces per pack, that is, 4,000 pieces per box, and the current price of each box B5 copy paper is 80 at 80-120 yuan, on average, the price of each piece of paper is only 2-3 cents, which is very cheap compared to other office equipment paper (such as some special inkjet printers).Copy -print paper is the most consumed material in the electrostatic copy, which is a manifestator of the quality of the copy. Therefore, when choosing a copy of the copy paper brand, you must pay attention to the quality of the paper, and you must master the correct method of copying paper.
The quality of copy paper is often reflected in many elements, such as "thickness, light, density, hardness, etc., so what concepts are these names, and how to judge the quality of copy paper from these factors?Let me introduce them one by one.
Smoothing: Smooth refers to the time required for a certain pressure of air under a certain pressure of air under a certain pressure of air under a certain pressure.The higher the smoothness of the paper, the better.The better the smoothness of the paper, the more uniform and complete the touches of the paper with the print head or the drum when printing or copying, the more fully the ink transfer, and the better the color effect of the print.Conversely, the ink with poor smoothness, the ink is not uniform, inadequate, and the paper faces the ink volume strong permeability, and the coloring effect is poor. It is often easy to bloom and fade the print ink.Therefore, when buying, try to use smooth paper, so that the effect will be better.
Glossness: Glossness refers to the degree of mirror reflection on the surface of the paper, which is expressed by percentage.The higher the luster of the paper, the more reflecting the light on the surface, the more bright the appearance characteristics can be displayed.In fact, in addition to mirror reflection on the surface of the paper, there is also a long reflection, which reduces the luster of the paper.The high luster paper, the more bright the ink color of the print, the visual effect of the ink color is also good.It can be said that the smoother the paper, the higher the gloss, and the higher the luster of the print.The luster of the paper is closely related to the smoothness, but the luster is not smooth. The paper has a glossy surface, not necessarily the smooth surface.From the perspective of the luster of paper, choosing the appropriate paper according to the characteristics of the print is very practical.If text -based books are based on text texts, it is advisable to use paper -like paper to avoid reflection and make the eyes look no fatigue for a long time.The print with a graphic version of the print should be selected with high glossy paper to make the ink color, thick, bright and pleasant.
Paper whiteness: Paper whiteness refers to the ability to reflect the full reflection after the paper is illuminated by light, and it is also known as the brightness of paper. It is expressed by percentage.The higher the whiteness of the paper, the more the surface can make the characteristics of ink color accurately.This is because white paper reflects the color light synthesized by transparent ink layer.Therefore, the high -grade paper can reflect almost all the color light, making the printed ink color bright and pleasant, and the visual effect is good.The low -white paper, because it only absorbs part of the color light, can neither show the contrast between the light and dark parts, but also easily causes color.If some appear yellow, some appear red, some are green, and some are blue.When the paper itself is colored, the color printed on the paper is the effect of the color of ink and paper.The analysis of the presence of the degree and color of the degree, and the purpose of correcting the bias by taking appropriate measures.
The absorption of paper: The absorption of paper refers to the absorption capacity of the linked and the solvents in the ink in the ink, which is usually represented by a percentage.The absorption of paper is also called ink absorption. Its strength is very sensitive to the shiny performance of hue and ink layers.Ink absorption paper, the ink of the printing is easy to fade, and the ink layer lacks luster.In addition, because most of the linked materials in the ink are absorbed by paper fiber tissue, the pigment particles are not enough to protect, and the ink film on the print is not firm, and it is easy to make the marks powder.Conversely, if the ink absorption of the paper is too weak, the ink layer of the print will not be attached, and the marks will not be easy to dry, which will easily cause the back of the stamp to dirt.Therefore, according to the characteristics of the printing, choose a copy of the copy of the paper brand with appropriate absorption to ensure the quality.
Thickness: The thickness of the static copier uses the thickness of the paper, generally between 64-80 grams per square meter, and some copiers can use a copy paper between 50-200 grams per square meter.In order to obtain improper benefits, many businesses now use consumers to buy environment without knowing their opinions, and they will put some paper with different thickness in the packaging paper, which will cause consumers to damage the interests of consumers. When we buy paper, we buy paper.Be sure to check it clearly that if you carefully check whether the packaging is complete, and the thickness of the sampling inspection paper is consistent with the explanation of the packaging.
The moisture of paper: The wet paper (paper with a large moisture content) is reduced due to the reduction of the insulation performance, so it affects the photocopy quality.
Its manifestation is:
A. It is easy to generate card paper phenomenon, especially if it is bonded on the optical conductor (turning drums) and cannot be separated, affecting the copy efficiency.
B. The images and characters are light and gray.If in the rainy season of southern my country, it will not be copied in severe cases.
C. Heating is easy to deform.Therefore, copying paper must be prevented from moisture, it is best to place in a ventilated and dry place.The finished copy of the finished product (500 pieces per bag) from the store, one pack must be removed after use.The penalty paper should not be opened before cutting.
At present, there are many printed paper and copy paper in the market. There are also many brand -name products. You can go to the top ten MAIGOO China in China before buying. This website not only shows us the list of the top ten brands of copy paper, butI also introduced the relevant information of well -known brands in copy paper.
Consumers can choose copy paper according to their printer or copy machine types. If they have better compatibility, the printing and copying effect will be better.Although the office is in contact with copying paper and printing paper every day, many office personnel have a very light understanding of paper. When buying, you can refer to the above performance parameters, which will be very helpful.
Especially for printing paper and copy paper, you can buy it with the above points.After absorbing so many knowledge about paper, I believe that as a buyer, you will have better observation when choosing a copy of the paper brand.
How to identify the good or bad of copy paper
Although the copy paper is a copy of a copy, its application scope is the most widely used. It can be widely used in a photocopy, needle printer, laser printer, inkjet printer, etc. When the output effect is not very high, especially in the needle printer and andThe use of laser printers is more widely used.Copy paper is the most consumed material in the electrostatic copy, which is an embodiment of the photocopy quality. Therefore, we must pay attention to the correct use of copy paper.
1 thickness.The thickness of the electrostatic copy uses the thickness of the paper, which is generally between 60-80 grams per square meter, and some copiers can use higher grams.
2 Surface light.Generally, the electrostatic copy paper, the surface light is slightly higher. If it is too smooth, it is not good for the fixed shadow, and it is not easy to solidify. It can be used by single -sided paper (single -sided copy) as required.The paper is better. The surface of the copy is better.
3 The density of paper.The fiber of the paper is better. Because the fiber of the paper is too thin or too thick, the first is to affect the quality of the photocopy imaging, and the other is that it is easy to produce paper hair, paper scraps, and dirty machines.
4 Paper is quite hard.Although some paper is appropriate, it is not necessarily suitable for copy machines. The reason is that weight and tide are two different things, and often because of badness, they will be wrinkled and blocked when they encounter resistance during the transmission process.
5 The moisture of paper.The moisture paper affects the quality of copying due to the decrease in insulation performance.
6 Cutting of paper.The fiber of paper has vertical and horizontal divisions. If it is cut into a tablet according to the direction of the fiber, then the long edge and the fiber of the paper are vertically vertical, the short side and the fiber are horizontal, and the static copy requires the fiber direction of the paper in the paper.Okay, because this is very good, the paper is small in operation and is not easy to tear.
7 Paper.Although the loading of paper in the electrostatic copier is a trivial matter, it must be put well, otherwise it is easy to stacked the paper paper. You must not put the lower part of the upper paper and the upper part of the lower part of the paper together.The same one inside the carton.
