The Development Of Dry Minilab Photo Paper Printing

posted on   2019-02-19 10:51:28

In the current civilian imaging market, most of the traditional silver salt color expansion machines are used. However, the traditional silver salt color expansion machine is unable to meet the needs of current consumers due to high energy consumption, high pollution, and quality, and will soon be eliminated by the industry.

The picture of silver salt printing is limited by the process itself. During the printing process, the bearing medium of the picture needs to be infiltrated multiple times in different chemical solutions, which will inevitably reduce the life of the carrier medium itself. Moreover, the picture is more susceptible to oxidation in the air due to temperature, humidity and light during storage, and fades.

The application of dry-type printing in the field of digital image output is particularly eye-catching, and the quality of its image output is increasingly praised by professionals. The ink-jet output technology has become the development trend of the global imaging industry. More importantly, the inkjet output photo is environmentally friendly and non-polluting, and is now in use in the medical output field. It is believed that in the near future, inkjet technology will be widely used in various image output fields. Dry-type printing is just a physical reaction of photo paper to absorb ink, which is completely different from the traditional photo printing technology. Not only is the speed very fast, but more importantly, it is completely in line with the low-carbon environmental protection concept: green pollution-free, no drying, no complicated procedures, no need for professional mechanics, no harm to the operators and customers.

Dry-type printing equipment is generally small in size and covers an area of no more than one square meter. It can be transported to the site where you need to shoot, and it can be output quickly and convenient for customers.

Currently popular dry color printers are :

Epson (SureLab SL-D700 and SL-D3000);

Fuji (Frontier S-DX100, DL600/650 and DL410/430/450);

Noritsu (QSS Green/Green II, D705/ 703, D502 and 1005HR);


Dry-type printing uses "living color D6" dye ink, which has six colors of cyan, magenta, yellow, black, light cyan and light magenta, which makes the output color more vivid and bright, and also breaks through the traditional color expansion. The appearance of the color jump phenomenon achieves a smoother and more natural color transition. The ink itself has good light resistance and stable properties. The most important thing is that the ink has the protection of the resin layer, so that the dye itself is not in direct contact with the air, and the dye is greatly reduced. The possibility of deterioration due to external environmental factors.

During the printing process, the ink adheres to the surface of the medium by electrostatic adsorption, in which no chemical reaction occurs, so the chemical properties of the ink and the medium itself are not changed.
