Sink ink-free printing: the crystal dye of photographic paper changes color when heated. Zink is the abbreviation of Zero ink, which means "no ink". Its printing technology and photographic paper are developed by Zink Company, and some people call it "thermal induction" technology. Printers using Zink technology do not need to be equipped with ink cartridges, and colors are produced by the heating of crystals on paper. Because of the reduction of ink cartridges, Zink photo printer is small and light, so you don't have to worry about the exposure of photo paper, but you should avoid high temperature storage.
The most important feature of Zink technology is its photographic paper. Zink photographic paper is not ordinary paper, but consists of special yellow, red (magenta) and cyan dye crystals. Dye crystals of different colors are separated by interlayers. When the printer heats the paper with different heat, the crystals will be heated and discolored in turn, thus producing the specified image.
Unpacking evaluation of Xiaomi portable photo printer: 10 seconds to upload, 40 seconds to print, price 1665 yuan, each photo 15 yuan ▲Zink photo paper is composed of yellow, magenta and cyan crystals stacked layer by layer. When printing, the printer will use different heat to heat the crystal and make the crystal change color. Therefore, Zink photographic paper does not need to use ink, toner or ribbon. And the paper is waterproof.
▲ introduction of ▲Zink technology. At present, there are more and more photo printers using Zink technology, but the photo imaging using Zink technology is unstable and prone to color difference.
Thermal sublimation: dyes are heated into gas and melted into paper fibers. Thermal sublimation technology is usually used to print pictures of cloth, shoes, gifts, cups and other items. Thermal sublimation technology is to heat the special ink to sublimate the ink directly from solid to gas, press the gas dye directly into the fiber, and then cure the dye. Therefore, thermal sublimation directly permeates the dye into the tissue of paper or articles, which makes it feel smooth and the finished dye will last longer than ordinary inkjet printing.
Thermal dye sublimation only presses 1 color at a time, and the number of transmitted colors determines the color depth of the color. So when you use it, you can see that the printed paper with different colors is spit out by the machine and then taken back for coloring. Thermal dye sublimation's color performance can reach 256, and the color performance will be more delicate.
Canon launched SELPHY SQUARE QX 10 handheld mobile phone printer, emphasizing that it will not fade after being stored for a hundred years ▲ thermal dye sublimation needs to load the ribbon before it can be used. Usually, after color printing, the photo printer will add 1 protective film, so the photo is waterproof and can prolong the storage time.
Polaroid: Using chemicals to complete darkroom procedures When the digitalization of photos was not popular, Polaroid had created the trend of developing with photos. Its principle is to concentrate the darkroom program of developing photos, and complete the shading and development process of developing photos with the help of chemicals.
Polaroid's technical focus is negative. There is a medicine bag hidden in polaroid film. When taking pictures and sending film, the camera will crush the medicine bag and let the medicine cover the whole picture, so that the film can be shaded and developed in a short time. Because polaroid photos are easy to fade, attention should be paid to exposure and other issues when using them, so the most common photo printers on the market at present are Zink technology and thermal sublimation technology, and polaroid is mostly used to reproduce feelings.
▲ Polaroid technology introduction.
The choice of photo printer can be based on the color and portability of photos. At present, the brands that produce photo printers are Xiaomi, Kodak and Canon. Introduced some brands of Zink and thermal sublimation technology. If you want to choose a photo printer, you can consider carrying it conveniently or pursuing detailed colors. In addition, we should also pay attention to whether photographic paper is easy to buy and the price of consumables.
