Paper is mainly selected from two aspects, one is the type, and the other is the thickness (the industry is called gram weight). Let me talk about the species first. There are many types of paper, but the paper we most commonly get (not special paper, special paper will be said later), mainly two categories, one is coated paper, the other is book paper. Book paper is not a professional concept, so here is a little supplement: First of all, book paper is not a professional concept, this is correct. Book paper is actually a common name. The main professional name is offset paper, at least in the Shanghai area where the author is located. It is better to use book paper when contacting the industry and outside the industry (mostly non-professional customers). Understand, here is a direct replacement. If it is a professional, it should be clear that if it is a non-professional, the individual thinks that the book paper is easier to understand than the offset paper). Coated paper has a coating on the surface so it can print brighter colors. Common fashion magazines, posters, and albums are mostly papers of this type. The thickness, brand, and surface brightness may be different (for example, the matt effect is matte coated paper, of course, it may be treated), but the type is generally the same, and the coated paper is mainly white. If it's a book or a magazine, if you feel heavy when you pick it up, it's mostly this type of paper. The printing shop you are talking about should be the kind of street printing shop, which usually provides this type of paper. Book paper, as the name suggests, can be understood as the printed paper. The textbooks we used to attend when we were young were generally book papers. Office printing paper is the most typical and most common book paper. The book paper is not coated, so the printing color is generally not very bright, mainly based on printed text. A small print shop is basically this kind of paper. If a book or magazine feels lighter, it is basically a book. Even if the name is not called a book, it is this category. In addition to white, the book paper generally has beige, yellow, and the like. Say the thickness. The thickness of the paper is generally described by the word "gram weight" (meaning how many grams of weight (per square meter of paper)). For example, a 200 gram coated paper having a thickness of about 0.18 mm and a 250 gram coated paper has a thickness of about 0.22 mm. How thick is this thickness? The cover of the newspaper's big fashion magazine, many of them are 200 or 250 grams, you can feel it. For paper of the same category, different gram weights correspond to different thicknesses. There will be slight differences between different manufacturers and brands, but not big. However, different types of paper, the same weight, will vary greatly in thickness. For example, 90g of book paper is much thicker than 90g of coated paper. The thickness of the paper is generally limited according to the market demand and the production process. The common weight of the coated paper is: 80, 90, 105, 128, 157, 200, 250, 300, 350, etc.; Common weights are: 70 (the weight of the paper that feels thinner), 80 (the weight of the paper that feels thicker), 100, 120, 140, 180, and so on. There are some differences in the choices of different brands, but the mainstream is basically these. In addition to the above two categories, you may have seen a lot of "paper" with different colors, different patterns and different printing effects, which involves another large piece of paper, which we collectively call: special paper. The paper is quoted here because many of the paper effects you think may not be the effect of the paper itself, but by other surface treatments in the later stages. Specifically, specialty paper is a very general concept, not a paper. Any paper that we think is unconventional can be called special paper. Special paper can be different in many dimensions such as color, thickness, texture, printing effect, gloss and stiffness. This is to choose according to your specific needs. You said that you want to print a work. It is not clear whether your work is similar to a single painting or a collection of works. Generally speaking, if you don't have special requirements, and the works are rich in color, the number is small, and the type is made of ordinary coated paper. If the number of pages is small, you can use a high thickness, such as 250g, 300g, if the number of pages is large, you can use thin, such as 105, 128 and so on. The quantity is not much. The coated paper is generally solved in the above-mentioned printing shop. The advantage of digital printing is that it is relatively cheap under the premise of being fast and small. The downside is that the quality of the prints is mixed, and most of them may not be very good. If the quantity is more than 1000 parts, then you can consider the printing factory. The quality that can be achieved by printing will be better than that of ordinary digital printing, but the final result is good depending on the quality control of the printing factory you are looking for. If you have high requirements, ample budget, and a large number of pages, you can consider special paper. This choice is large. You can ask the printing factory to provide you with samples and explain them accordingly. Ordinary street printing shops may not be able to meet this demand.
