Influence factors of inkjet printing paper effect:
1. Color inkjet printing paper quality:
Color inkjet printing paper, absorbent on inkjet printing ink drying performance of ink pigment fixation performance affect the inkjet paper effect, so the coating composition and coating structure of color inkjet printing paper to play an important role in the printing effect.
Inkjet printing ink with dye ink, pigment ink, oily ink. Dye ink will fade, waterproof in ultraviolet light irradiation; pigment inks with good light fastness, water fastness, but the color is just passable, oily ink is mainly used for outdoor product trademarks, advertising, has the characteristics of good water resistance, light resistance. The color inkjet paper is water-based dye ink, usually by the dye, solvent (water, ethanol), adhesive, additive composition. When printing ink droplets from the nozzle to the paper requirements in a short period of time of drying, this paper not only with the nature, but also a greater impact on the nature of the ink, generally use the special brand ink matched with a printer and printing paper.
3. Print system
Printing system refers to the temperature and humidity conditions when printing, printer type and print settings, etc.. Print in a high humidity environment, will not cause absorption, bleeding and other phenomena. The piezoelectric micro bubble type printer printer and ink-jet printer at normal temperature and pressure in high temperature high pressure, the two printer control precision of the size and shape of the ink is not the same, can cause different printing; at the same time the print settings are not the same, the printing effect is not the same. For example, at the same time in the photo quality printing state, the resolution is set to 720dpi and 360dpi, the two printing effect is not the same.
Special paper color inkjet printer called color inkjet printing paper. This paper is smooth, print out photos or renderings with a clear sense of hierarchy.
If you want to print photos, it is recommended to use photo paper. Paper is designed for the production of printed photo paper, both a certain thickness and hardness requirements, but also bright colors, long time to maintain color. Technically speaking, the paper is based on ordinary paper coating is coated with special paper, it looks more bright, and can quickly absorb the smallest particles of ink, solidified, long time keep bright color photos. In addition, the paper texture is relatively hard, high resolution printing can also effectively prevent ink penetration. The paper is divided into four types: glossy photo paper, photo paper, glossy paper and high resolution paper (thick photo paper).
The color inkjet printing paper is an acceptable body of ink jet nozzle of inkjet printer. Its basic characteristic is that the ink absorption speed is quick, the ink drop does not spread. Specific requirements: 1. Good record, strong ink absorption, ink absorption speed, the droplet diameter is small, nearly round shape; the recording speed, namely high density, continuous tone, clear picture; the preservation is good, the picture has certain water resistance, light resistance, preservation of certain and fastness in indoor or outdoor; 5 have a certain strength and fastness of coating, coating is not easy to scratch, no static, have certain smoothness, bending resistance, folding stretch.
Color inkjet printing paper is a new type of recording paper, because of the rapid development, there is no uniform quality standards. From the technical specification of the domestic, the corresponding quality detection range and detection standard, according to the color inkjet printing paper quality will not produce this standard is lower than that of similar foreign products, but the market price will be lower than 20% ~ 50% of the imports of similar products. Therefore, the domestic color inkjet printing paper has a strong market competitiveness.
Color inkjet printing paper is very different from ordinary paper, this is because the color inkjet printing usually use water-based ink, rapid absorption and diffusion and general paper received water-based ink, results from both color or from the definition are not up to the requirements of printing (using water absorbing materials can not absorb ink difference); color inkjet printing paper is paper products deep processing, it is the ordinary printing paper surface through special coating, which can absorb water ink and make the ink droplets spread to the surrounding, so as to maintain the original color and clarity.
