A3 copy paper these little knowledge you all know it?

We should not be too familiar with office paper. We use A4 or A3 copy paper for office work. Therefore, this kind of paper is also a must for office purchasing. For office buyers, they should understand the characteristics of the paper before purchasing this type of paper. Today, Xiao Bian uses A3 copy paper as an example to describe some of the small knowledge that copy paper should be aware of when buying. 1: The price is the source Why is price the source? Because reviewing the richness and diversity of the types of office supplies on the market today, and making people feel dizzying, and the quality of products is similar, what is the key to attracting consumers, of course, is the price, in the same product, the same quality Among the different prices, of course, the price will be chosen to be relatively cost-effective to buy. The price of this type of A3 copy paper is about 30~37 in the market, which is bought in physical stores, and if you choose to go online to buy its price may be cheaper. However, some prices will be lower but postage will also be similar to the physical store, which depends on personal preferences. Another point of the quality of paper will also affect the price changes, good quality, if you need a lot, then the price will be 3-5 yuan more expensive. However, for the enterprise, the demand for this type of paper should be very large, so it is generally chosen to use more expensive paper, because after all it is used for office use, unlike the usual use of scratch paper. 2: Size of standard A3 paper Many brands in the market are under the banner of the regular brand name. However, rough production is used in production. The size of the paper used may sometimes appear less than a meter. What is the standard size of the A3 paper? The implementation of the office paper size is defined by the International Organization for Standardization's ISO 216. ISO 216 defines the A, B, and C sets of paper sizes. The C group paper size is mainly used for envelopes. Before ISO 216 was widely adopted, there were many different paper formats internationally. These formats are not a coherent system, and many are not defined in metric units. The ISO 216 format follows the 1:2 ratio; the two sheets put together have the same aspect ratio and sides. In fact, the simple operation is to enlarge an A4 paper and copy it onto an A3 copy paper. If it coincides with A3 copy paper, then this is in line with the A3 standard size. The realization that there are still a lot of people who buy inferior paper because they are greedy and cheap, so we first choose the paper that fits our specifications according to our needs, and then we must carefully look at the size of the paper. Two A4 papers for comparison, and then not to go to regular shopping malls, ask for invoices after purchase to ensure that the paper can not be returned to specifications. We usually must be able to protect their own interests in the purchase of things, not to allow those unscrupulous traders to take advantage of.
