How to choose a good outdoor photo machine solvent ink Here are some of the hopes to help you:
first, excellent stability: inkjet ink Its principle is that organic pigments are evenly distributed in the organic solvent system, some inferior ink because of its choice of raw materials only the pursuit of cheap, pigment particles of different sizes, suspension The system is very unstable, with the passage of time, the change of temperature, will produce stratification, precipitation phenomenon. Reaction to the inkjet machine will be in the ink barrel, ink cartridges, ink tubes and nozzle ink cavity in the production of precipitation, commonly known as "sludge." The direct result is that the ink supply is not smooth, the amount of ink ejected from the printhead is not uniform, affecting the screen, serious blocking of the nozzle, so that the life of the oscillating crystal is extremely shortened, that is, the so-called burner. Generally good ink does not need to be shaken or oscillating with ultrasound before use.
Second, excellent sun resistance and weather resistance: because the outdoor spray painting surface for a long time hanging in the outdoor, ultraviolet, acid and alkali, dust and air pollution will affect the screen, so in the choice of ink as far as possible to choose the sun-resistant level 7 (the highest level of 8, due to the color of the reason, Individual colors can only be up to 7 levels in the world) above and weather-resistant 5 (up to level 5) products.
Third, raw material quality: raw materials mainly because of its price different quality also has a great difference, the impact on the nozzle is quite large, such as purity, PH value, water content, impurities, etc., will directly affect the service life of the nozzle. Therefore, high-quality raw materials are an important guarantee of high quality ink. It is recommended that users reduce the cost of ink at the same time, do not ignore the quality of ink raw materials after all, inkjet ink on the state and performance of the inkjet machine is too much impact.
Four, excellent color area expressive force: organic pigment color has many hue, all kinds of hue will produce different color gamut effect. Choosing as much color as possible to reflect the maximum color gamut and local consumer preferences is one of the main factors in choosing ink.
Five, ink safety and environmental protection: high-quality ink requirements are not flammable and explosive, the personal impact is reduced to a minimum. And now some of the ink on the market, only in pursuit of low-cost, the international ban on the use of benzene series of solvents applied to inkjet ink, although temporarily there are users to use, but with the enhancement of user awareness of environmental protection, will eventually be completely eliminated.
Six, good usability: excellent ink in the printing machine normal inkjet process, do not need to wipe frequently, clean the nozzle, so that the waste of ink, but also reduce the efficiency of the inkjet machine. Even produces chromatic aberration, which directly affects the quality and efficiency of the inkjet.
