How to use eco solvent inks correctly in printers
2022-09-30 10:42:46When it comes to solvent ink, everyone will think of the big spray used for printing outdoor advertisements and the slightly pungent ink smell. The main components of solvent based inks are organic solvents, and esters and ketones are generally used. Solvent based inks are the patent for outdoor spraying. They are specially designed to deal with this kind of ink: from the print head to the pipeline and finally to the cleaning unit, All of them have been adapted to this ink. Of course, the pictures produced by inkjet printers using solvent based inks are generally not very accurate.
Taking Epson's print head as an example, the picture accuracy of a universal printer using water-based ink is very high, but it cannot be used outdoors. Due to some attractive characteristics of solvent ink, there are almost no media that it cannot print on, and outdoor is more. There is a broad field of development, so it is under this circumstance that the eco solvent ink begins to develop. First of all, the use of eco solvent ink on the high-precision print head produces high-precision pictures, and can also be applied to uncoated substrates. It can also prevent UV ultraviolet rays, suitable for outdoor use, and has quickly become the darling of the new generation.
So, can eco solvent ink be applied to desktop printers? So how is this ink used and what are the problems in use? If you want to know the previous question, you must first understand the characteristics of eco solvent ink.
First, the characteristics of weak solvent ink
Desktop printers are not designed to use eco solvent ink, and there are few supporting materials and accessories in eco solvent ink. Although the eco solvent ink has made many improvements to the solvent ink, for example, some efforts have been made in how to protect the environment, and the filtration is more careful, but the eco solvent ink is always a solvent based ink, and some characteristics of the solvent-based ink still exist.
Quick drying of ink.
The quick-drying characteristics of eco solvent inks make it more important to choose a printer.
The main component of eco solvent ink is still organic solvent.
The main component of weak solvent ink is organic solvent, which has certain corrosion and chemical reaction than the commonly used water based ink, so the products of high-quality ink manufacturers must be used.
How to use weak solvent ink correctly
Due to some characteristics of the eco solvent ink itself, the selection and supply must be very careful. Some friends use eco solvent ink, the outer ink cartridge leaks, the elbow connecting the ink pipeline is blocked, and finally the print head is disconnected. So to use with corrosion-resistant continuous supply or ink cartridges, especially for desktop printers, you must pay attention to this. If the equipment is not used for a long time, pay attention to the cleaning of the print head part to avoid the blockage of the print head due to the volatilization and solidification of residual ink.
Eco solvent ink can achieve coating-free printing on some materials, or use printer heating and other means to achieve coating-free printing, but for some smooth surfaces, ink alone is powerless, and the ink will accumulate together and cannot Clear imaging. Then it must be used with a special coating liquid, and the three advantages of using the coating:
The drying speed is fast. The coating is prepared with special chemical raw materials and used in combination with eco solvent ink. It dries within one minute after printing, especially on smooth materials such as glass.
The printing quality is good. It is directly printed on some materials without coating, mainly on smooth materials that do not absorb moisture. The effect is poor, but the effect after coating is extraordinary.
Wear-resistant and waterproof, because the coating ingredients contain adhesive ingredients, the adsorption force between the ink and the material after printing is very close, far exceeding the wear resistance of the uncoated state.
