Many people do not understand the problem of common standard paper size when using copy paper for office work. They often hear office paper requirements for A3 size copy paper, A4 size copy paper, or B4, B5, etc. The standard paper sizes for these specifications are not known to everyone. A thorough understanding and understanding of this issue is also a very important thing for people who use copy paper in their work and study. So, what is the standard paper size? How to choose paper in daily work and study? Let's take a look at it below.
First, common standard paper specifications
For those who want to know the standard paper size, you should first understand the specifications. In general, the standard paper specifications include: A3, A4, A5, B4, B5. Its various dimensions are: A3=420&297mm, A4=210*297mm, A5=210*148.5mm, B4=250*353mm, B5=250*176mm.
Second, how to choose the commonly used standard paper
When people are working in the office, the following items should be noted when selecting common standard paper:
1. The surface luminosity of the paper. For the copy paper used daily, the surface luminosity is only slightly higher, and if it is too smooth, it is not suitable for fixing, and the curing effect is not good. It is ok to use a single adhesive tape in accordance with general copying requirements.
2, paper density. The fiber of the paper should be dense. If the fiber of the paper is too thick or too thin, the quality of the copy image will not meet the copying requirements, and paper scraps and paper hair may be caused, which may adversely affect the machine.
3. The weight of the paper. Paper that is too heavy or too light will be rejected by the printer or copier, so try to choose between 70-90 grams of paper per square meter when selecting paper to ensure the quality of printing and copying.
4. The condition of the paper. The selected paper should be clean and dry. If the paper is damp, the correct paper feed will not be possible, and the paper path will also cause folding or tilting, and the printed or copied effect will be poor. If it is a laser printer, the wet paper copying effect will be very blurred. Therefore, the condition of the paper is a very important choice.
After the above introduction to the common standard paper size and selection principles, I believe that everyone will be able to effectively select high-quality copy paper.
