What's the name of the paper on which the photos are developed?

Classification of digital photographic paper

I don't know if you feel this way. When taking pictures, the sound of the camera shutter is very nice! Photography helps us leave beautiful things and moments. We use photos to collect, and photo paper shoulders heavy responsibility! In addition, today's commercial development puts forward new requirements for photographic paper-variety, good quality and low price! There are indications that the photographic paper market in China is in a period of rapid growth. According to the survey, the photo printing paper market will grow by 50% every year in the next year or two. Merchants are eager to seize the market and innovate constantly. How to buy the most suitable photographic paper in such a complicated market?

Photographic paper is specially made for printing photos. It has certain thickness and hardness requirements, but it can also be brightly colored and keep its color for a long time. Technically speaking, photographic paper is coated with a special coating on the basis of ordinary paper, which makes the paper look brighter, and can quickly absorb tiny ink, solidify it, and keep the photos bright for a long time. In addition, the paper is hard, and high-resolution printing can also effectively prevent ink penetration. According to the different coating and paper media, photographic paper can be divided into glossy paper, photographic paper, glossy paper and high-resolution paper (thick photographic paper). It is helpful to know the following knowledge before buying.

Glossy paper: The full English name of glossy paper is "photo quality glossy film". Smooth paper, as its name implies, is characterized by a glossy surface on the printed photos. In addition, it has the texture of traditional photos and good moisture-proof effect, so the printed photos look very comfortable. It is suitable for printing high-quality photos, as well as recording envelopes, report covers and so on. When buying photo paper, it is the first choice.

Glossy paper: Glossy paper is called "photo-grade glossy paper" in English. Compared with glossy paper, glossy paper is more detailed and has a strong luster on the surface. But it doesn't mean it is better than glossy paper, because it is not as thick as glossy paper. Relatively speaking, its price is relatively low, and it is suitable for printing some artistic photos with large print volume and materials with large text volume. But the art photos should be kept well, which is economical. Typical glossy paper products include Epson's photo-grade glossy paper S04 1 126, Canon's GP- 10 1, HP's advanced photographic paper C6039A and so on. There are three common sizes A2, A3 and A4, and there are also some high-standard glossy papers in China, such as the golden flagship glossy paper.

Smooth photographic paper: smooth photographic paper is called "photo paper" in English, and its surface is covered with resin layer, which is very smooth, bright white and shiny. The photos printed with it can produce the maximum color saturation, bright colors, vivid details and attractive, which is very suitable for printing some advertising banners, posters, product catalogs and so on. Of course, printing photos, greeting cards, Christmas cards, or making family and personal photo albums are all very good.

High resolution paper (thick photographic paper) Thick photographic paper: The biggest feature of this kind of photographic paper is "thick", so the price is higher than other photographic papers. This is mainly because its coating is thicker than ordinary inkjet printing paper, its surface is very flat, and its printing effect is also very good, which is close to the quality of traditional photos. If you want to create bright and dazzling images, this is an excellent choice, such as using it to print thick posters and some craft paintings. The representative products in the market are Epson's high-quality 720dpi inkjet printing paper S04117, Canon's high-resolution paper HR-1KLOC-0/,HP's advanced inkjet printing paper 5 1634Y, etc. Common sizes are A3 and A4, but it is recommended that you do not choose them.

Of course, there is more than one classification method. Classifying from different classification standards means understanding and evaluating photographic paper from different angles, which will bring you unexpected gains. According to the different coating methods and materials, photographic paper can be divided into:

Swelling photographic paper: It is a swelling coating formed by coating polyvinyl alcohol (PVA) on the base paper, which is called swelling paper. Its surface is made of gelatin, polyvinyl alcohol and other polymers, forming an ink absorption layer. When printing, ink drops are sprayed on the surface of the ink absorption layer, and the polymer absorbs moisture and expands to show various colors, which has a very good color reduction effect. However, due to the limited expansion speed of polymers, the drying speed is very slow. Especially the new six-color piezoelectric printer, the printed image has serious accumulation defects, and the clarity is not satisfactory. Its water resistance is poor, although it can be improved by adhesive modification, but its ink absorption is reduced, that is, the ink absorption and water resistance are contradictory. Generally speaking, its production cost is relatively low, but its ink absorption performance is poor, drying is slow, and it is not waterproof. After printing, it needs to be covered with plastic film, so there are many later processes, and the increased cost is relatively high, and the effect is far less than that of traditional photos. It belongs to low-grade products. At present, the technical level of domestic manufacturers is not much different, and most products belong to this category.

Cast-coated waterproof photographic paper: Cast-coated waterproof photographic paper, whose coating is micron-sized silicon dioxide, can reach the level of traditional photographic paper in brightness and whiteness after special process treatment. It is the flagship product of some powerful inkjet material manufacturers in China. It has a waterproof coating, but the base paper is the same as the expanded photographic paper, so the overall waterproof performance is poor, and the photographic paper will be deformed to some extent after printing high saturation pictures; At the same time, the fineness of the coating is not enough to meet the requirements of ultra-high precision printing. But for ordinary photo printing, it is a good choice.

RC photographic paper: Like traditional photographic paper, its base paper is coated with waterproof PE coating resin on both sides of the base paper, and the coating is nano-silica material (the particle size is below 150 nm), forming extremely fine inorganic-organic hybrid fine particles. After the ink is sprayed on it, micropores appear like a honeycomb soon. Due to the special micropore structure, the coating has strong ink absorption and can also show a good layering for the darker parts. Drying is also very fast, and you can touch it directly when you come out of the printer; Its coating material is very fine and high brightness, which can match high-precision photo printing. At the same time, the waterproof performance is also good. If the photo is accidentally splashed by water, just dry it and keep it as it is. To sum up, its advantages are high water resistance, high ink absorption and quick drying. RC photographic paper is the development direction of ink-jet printing media, and its printed image quality can be comparable to that of traditional silver halide photographic paper. With the development of domestic RC photographic paper manufacturing technology, products can compete with Germany and become the mainstream of high-end digital printing. Of course, its price is also relatively expensive, which can be decided according to its own economic situation and the preciousness of photos.
