How was the photo developed?

In the past, black and white were basically developed and enlarged by hand. After entering the photo era, color photos are printed by printing equipment.

To realize the output of digital photos, expensive secondary investment must be made, such as buying professional printers and expensive printing paper. Now, through digital printing equipment, digital photos can be easily output to traditional photographic paper with high quality.

Digital printing is a high-speed, low-cost and high-quality method of making digital photos by exposing digital images on color paper and outputting color photos through color amplification. The principle is complex, involving a lot of professional knowledge, and the technologies adopted by major manufacturers are not the same. There are two brands of digital printing equipment, Fuji and Kodak. Like traditional photo printing, these two brands occupy more than 80% of the China market.

Generally, a digital printing system consists of a high-precision scanning system (for inputting traditional negatives), a digital exposure system (for restoring digital images to images and exposing them on photographic paper) and a photo development system (for developing, fixing and drying the exposed photographic paper). Because the scanning and developing system is very mature in technology, there is little difference in technical performance between the two systems of various brands of equipment, and the key equipment-digital exposure system has high technical content, and the technologies adopted by various manufacturers are different, which directly affects the printing quality of digital photos.

The most important investment for a digital printing factory is printing equipment. With the increasing demand of consumers for image quality, high-quality machines can provide high-quality printed products. At the same time, because of the low failure probability of high-quality machines, it is bound to improve the printing speed and not delay the time for consumers to take pictures.

At present, the printing equipment on the market can be mainly divided into two categories: one is imported equipment, the price is about 200,000-500,000 yuan, represented by brands such as Fuji and Kodak; The other kind is domestic equipment, the price is about 80-65438+10,000 yuan.
