What's the difference between inkjet and developed photos?

Different equipment: digital printing uses printers, such as HP, Epson, Canon, etc. It is very popular in the market, and the price is around 1000 yuan. Digital printing uses professional printing equipment, such as Norris of Kodak Company and Magic Hand of Fuji Company, and the price is in the order of hundreds of thousands or millions.

The principle is different: the technical principle of digital printing is to expose the digital information of stored images on silver salt photographic paper with the help of laser, and then develop and output them through traditional processing technology to keep the quality of finished photos consistent, while digital printing adopts inkjet technology, and the color of finished photos will change after a period of time. Usually the printed photos will fade in the air for a long time, while the unprinted photos will last for a long time.

If you look closely, you will find that many printers use "photo-level printing effect" as their advertising selling point, which certainly shows that the technology, performance and even printing quality of various printers are constantly improving, but at the same time, it is acknowledged from the side that the quality of digital printing is better than that of color printing.

As we all know, there are many factors that affect the quality of photos, such as the grade of the camera, the experience of the operator, the limitation of the environment, the settings when shooting and so on. Users can't always take satisfactory images. A master photographer is not necessarily an expert in the application of graphics processing software. Even if ordinary users can properly adjust the photo effect before color printing, they may not be able to handle the output effect to the best state. When users choose to use Kodak digital printing, professional technicians here will first correct the photo quality through computer-related software, such as correcting overexposure or underexposure, increasing color clarity, adjusting background density, and correcting contrast-the top quality assurance of digital printing will not make users feel any regret when browsing photos. This advantage in post-processing is incomparable to traditional optical printing and digital printing, which ensures the printing quality.
