Full understanding of the "blood" of inkjet printers - Ink

As an ink jet printer for office equipment, ink is the fastest, most expensive and most expensive consumable. Learn more about ink, use the printer better, and print better images. Significance.

First, the basics of ink Ink composition Ink is usually composed of solvents, colorants, surfactants, PH regulators, driers and other necessary additives. Among them, the solvent accounts for the largest proportion in the ink of inkjet printers and is the main component. The performance of the colorant directly affects the color and hue of the printed image, and its own color, mixing performance, solubility, acidity and alkalinity, and particle size are particularly important.

Ink classification According to the color base classification, ink can be divided into dye ink and pigment ink. Dye inks are also the inks used by most current ink jet printers. It is dye-based ink, because the dye can form a stable composition in the molecular state and solvent, so the dye ink printing image resolution, good resolution, but poor lightfastness, water resistance, used in indoor applications .

Pigment inks are inks based on pigments. Pigments are generally present in the solvent in the form of particles. The pigment ink is the particles dispersed in the ink, and the pigment particles are left on the surface of the substrate such as paper, so the printed image has high color intensity and gloss.

At the same time, when it is exposed to the external environment or sunlight, it is resistant to light and high temperature decomposition and is suitable for outdoor use. According to the solvent ink can be divided into: water-based ink, oil-based ink. The aqueous ink is an ink that uses water and a water-soluble solvent as the main component of the dissolving chromophore. Oil-based inks are water-insoluble solvents that act as the main component ink for dissolving chromophores.

The main performance parameters of ink Inks for inkjet printers require high thermal stability and chemical stability. The performance parameters that affect ink printing are mainly the following:

One is viscosity and surface tension: Viscosity is the resistance to liquid flow. The surface tension of a liquid is related to the formation of droplets. In general, inkjet inks have a low viscosity and high surface tension to ensure good flow properties. And droplet morphology.

Second, the PH value: the concept of liquid pH, the more acidic the solution, the lower the PH value, on the contrary, the solution of the alkali, the higher the PH value. In order to prevent the ink from corroding the nozzle, the pH should generally be between 7-12.

The third is the conductivity: In the ink, the conductivity value is used to reflect the level of salt content. In general, the salt content should not exceed 0.5% to avoid clogging caused by crystallization of the nozzle.

Fourth, dispersant: a kind of surfactant, its role is to improve the physical properties of the ink surface, enhance the affinity of ink and sponge, wettability. Therefore, the ink stored and transferred through the sponge generally contains a dispersant.

Second, ink new technology summary In recent years, ink manufacturing technology continues to introduce new. The successful development of each new ink technology will greatly improve the printing level.

Epson Century Enamel Waterproof and Luminous Epoch Century Enamel Waterproof and Lightfast Ink is based on the perfect combination of pigment ink and special resin coating. The ink is evenly arranged on the surface of the paper, the light reflection is more even, and the printing effect becomes more outstanding in the ordinary. The same outstanding performance on paper.

Century Color Waterproof and Lightfast ink uses pigment ink for all colors and uses a special resin coating. It can withstand the test of the environment for a long time and can be kept as new for a long time and is widely used in the field of commercial printing. After a professional test, the photo printed with Century Waterproof and Lightfast ink can be kept in the picture frame for 120 years without discoloration, and it can be kept in the album for more than 200 years without fading.

The special resin coating encapsulates the particles of the pigment ink in the resin coating so that it can be uniformly dissolved in the water, ensuring that the ink density remains constant throughout the life of the cartridge.

The resin coating can also help it to solidify on the surface of the paper, making the printed colors more clear and vivid, and solving the problem that pigment inks can hardly meet the gloss of traditional photographs. In addition, the protection provided by the resin coating can completely prevent damage caused by light and moist air to the printed work, and is not easy to fade, damp or moldy.

Based on pigmented inks and special resin coatings, Century Enamel Waterproof and Lightfast Ink has become even more effective in printing photos and printing texts, making it a true “full-function ink”.

HP Vivera 9 Ink Technology HP Vivera 9 Ink Technology adds a new blue HP Vivera ink to the original 8-color ink, which greatly improves the lack of blue color in the photo. Not only can it better show the beauty of the sea and the sky. And Vivera Ink gives the shaded areas a variety of subtle shades that clearly outline the light and darkness of the light.

HP's new Vivera Ink formula has outstanding fade resistance, and can achieve over 100 years of fade resistance using HP Vivera Ink and HP Premium Inkjet Photo Paper. In particular, Hewlett-Packard Co., Ltd. has developed special pigments that can display bright, vivid colors and have greater resistance to fading, both on plain and special paper, as well as HP photo paper.

Vivera ink formulas are chemically more compatible with the various substances in HP cartridges, flow more efficiently, and eject into the complex components of the print cartridge for optimal coordination and optimal performance for output The photographs achieve the best balance in terms of outstanding color, longest storage time, and reliability.

Canon ChromaLife100 Ink Technology Canon's ChromaLife100 ink technology is a combination of FINE print nozzles and newly formulated inks combined with original paper.

The newly formulated color inks include the photos of the CLI-8BK/CLI-8Y/CLI-8M/CLI-8C/CL-41/CL51 cartridges that use the new generation of Dye ink to print on genuine Canon photo papers. Can be stored in the album for 100 years. In line with the original paper, the new ink allows the output of the picture to remain in a hot, humid environment, and the ink remains sharp.

Canon also introduced the latest pigment inks PGI-5BK, PG-40, and PG-50, which can condense on the surface of the paper, quickly dry, print the edges with clear edges, and are more suitable for text printing. The water resistance has also been improved and can be improved. The picture produces better protection, with features that are not easy to dry, not easy to fade, and low cost. $Page break $

Third, the use of ink and techniques to save ink tips The price of ink is expensive, is the main aspect of the cost of printing, how can reduce the use of ink is the most concern for each spray user, the following HP spray as an example Explain how to save printing ink.

When printing text or graphics, everyone does not have high quality requirements. At this time, setting the “Print Quality” option in the print mode to “Fast” will be able to meet the printing requirements. This will not only be more ink-consuming, but also printable. faster.

HP inkjet printers support single-cartridge printing. When black ink is used up, the HP cartridge complementary technology continues black-and-white text printing by mixing black between the magenta and blue and yellow color inks. It greatly improves the utilization of ink and ensures unimpeded printing.

Using software to control the use of ink can save ink to the limit. For example, Inksaver is such a software, it can reduce the print quality slightly, just set a reasonable percentage of ink savings, you can achieve substantial reduction in ink consumption.

Reducing the number of times the ink jet printer is turned on can also save ink consumption because the printer automatically cleans the print head and initializes the printer once each time the ink jet printer is turned on, and ink is filled in the ink delivery system, thus causing a large amount of ink to be wasted. Drop it. Most ink jet printers have buttons to clean the print heads, and also have a three-speed cleaning function for quick cleaning, regular cleaning, and thorough cleaning. In general, it is sufficient to use quick cleaning because the more thorough the cleaning, the more ink is wasted.

Precautions for the use of ink In winter and summer, the ink that has just been bought back or stored in the storeroom may not be smooth and sometimes may not work properly due to the temperature difference if it is used immediately. The best method is to take the ink a few hours in advance and use it until the ink temperature reaches the required level.

In addition, use the same brand of ink as much as possible, because each manufacturer's ink chemical composition is different, if frequent replacement, it may cause damage to the ink cartridge and print head. In addition, the ink cartridge has a certain life span, and the number of ink refills is not unlimited. Usually, the safety method is to replace the ink cartridge within ten times.

Precautions for Filling Ink The ink can be used only after it has been inked. When filling the ink, clean the tool with pure water and dry it. There should be no alkaline and acidic solvents. The ink-filled ink cartridge is preferably original and undamaged. It is best to remove the original ink and refill it with ink.

The ink speed should not be too fast during ink filling to prevent the ink head from leaking ink. For some sealed cartridges, you can drill holes in the upper part of the cartridges, then carefully inject the ink into the holes with a syringe. The ink must be filled in an appropriate amount, not more than half of the cartridges, and the holes should be sealed with transparent glue after ink filling. Do not leak gas to prevent ink leakage.

For ink cartridges with ink refilling holes and vent holes, be careful to seal the ink head before filling the ink, insert the needle into the exhaust hole of the cartridge, and then fill the ink refill hole with the syringe. Do not add ink to the ink head as this will damage the mesh and cause impurities to clog the ink head.

Fourth, the purchase of ink In the purchase of ink, in addition to ordinary color ink, there are special photo ink and fluorescent ink points. Some brand models of printer products can also independently purchase different colors of ink. If you often print black and white documents, or print PowerPoint images, then ordinary color inks and black ink may be more suitable for you. When printing a black font, the ink automatically mixes black with several colors, but the printed effect is not as good as a single black ink.

There are three main types of ink on the market today: original, compatible, and counterfeit inks.

Original ink is the original ink is the printer manufacturer for their own production of ink jet printer specified matching ink called original ink, its clear identity is the same with the printer and the printer factory standard (such as Epson, HP, Canon, Lexmark, etc.), original ink Quality is the most reliable, while the original ink and printer
