Analyze printer ink and paper secrets

Through years of practical experience and constant exploration, we have summarized some details and in-depth knowledge about ink and printing paper. We hope to help everyone understand ink, ink and various types of paper! At the same time because we are not specialized in ink and paper research. What we can dedicate to us is only the experience we have accumulated in these many years and some of the details disclosed by professionals. Therefore, there are inadequacies in the hope that all of you will come together to discuss and jointly improve common progress is our goal!

Printing ink

The ink color is provided by two types of materials, one is a dye and the other is a pigment.

Dyes are characterized by being transparent, which changes the color of the transmitted light by selectively absorbing certain spectral components of the incident light. Therefore, dye ink can be used not only to print color photos, but also to print transparent light box pieces. Traditional color photographs, transparent positive films are dyed to color.

The original materials of many kinds of dyes are insoluble in water, so some special solvents are required to dissolve them first and then add water. These dissolved dye solvents are somewhat detrimental to the materials used to make the ink head. I commissioned a company to develop yellow ink five years ago. As a result, the ink supplied to the ink was quickly damaged. After analysis by the company's experts, it should be dissolved solvent of yellow dye to destroy the ink head.

The durability of the ink is basically determined by the original material of the dye. It is not known which dye is more durable. In addition, we have no way of knowing which dye it used to formulate the ink we bought. I think the basic principle is definitely that more expensive inks are generally more durable. Because the raw material of the dye is so cheap, it must have certain defects. Inevitability is definitely one of the major defects. The reason for your price is basically more durable, and the color may be special. There are fewer people.

Magenta in EPSON dye inks is a less durable color. We used it to print color cards on matt paper. We found that if exposed to the air, we don't need to see the light. As long as one month, the color will fade and the grayscale will become green. The EPSON ink imitation of some manufacturers is even more frightening. After printing this evening, if it is not coated, it will fade the next morning.

Ink is used in different printers and other things are added to change its viscosity, surface tension, and possibly its coefficient of thermal expansion or boiling point, to allow different printers to be ejected smoothly. These additives should also be safe for the ink head.

Solvents and additives used on different printers make different printers have different options for paper. As we all know, the EPSON dye ink printer picks up paper, but if its ink is replaced, it can be used just like an HP printer.

In formulating compatible inks from different manufacturers, we discovered that most inks are not formulated with one dye. The phenomenon is that the color saturation of most inks sold in the market is higher than that of the original ink. We usually use two or three inks in combination to match the color of the original ink.

Pigment inks were formerly made by grinding mineral pigments. Today's pigments may also have non-mineral materials. In general, it is made of solid pigment and then emulsified to make ink. Its main feature is that it is more durable and the more granular the more durable it is. It is not so much lowering and lowering, but it is not so good. 暮 缮 缮 缮 缮 缮 獭 獭 獭 獭 獭 獭 獭 獭 獭 獭 獭 . . . . . . 16.

No oily ink is used in small printers. Only large outdoor sprayers use oily ink. The ink is similar to printing ink, but the printing ink is usually used in transparent dyes, while the outdoor sprayer uses the ink formulated with the pigment, the outdoor spray nozzles are very large, not easy to plug. This ink uses organic solvents and film formers like paint. The surface of the material is very low. Not only is it resistant to water and light, it is not very good quality.
