Detailed EPSON technology

Micro Piezo Printing Technology

Piezoelectric print printing utilizes piezoelectric crystals that can vibrate at a fixed frequency in the event of a voltage change at both ends. Electrical signals drive the piezoelectric crystals in the ink jet chamber to move and force the ink to eject. The micro-piezoelectric technology divides the control of the ink droplets during the ink-jet process into three stages: receiving, pushing and receiving. Before the ink-jet, the piezoelectric element first shrinks slightly under the control of the signal; then, the element produces a large extension. The ink droplets are pushed out of the nozzle; after the ink droplets fly away from the nozzle, the far piece will shrink again, retracting the ink level from the nozzle opening very cleanly. In this way, not only the size of the ink droplets is precisely controlled, but the ink droplets ejected each time have a uniform shape and direction of flight, and no "satellite ink droplets" are produced. Because of the short time of addition and subtraction, the micro-piezo is much faster than thermal inkjet printing under the same number of nozzles.

Intelligent change of ink drop technology

EPSON's unique intelligent conversion ink droplet technology can analyze the color composition of each area of ​​the image. By adjusting the signal size of the driving transistor, droplets of different sizes can be generated. In a single printing stroke, large, medium, and small can be ejected. Drops of ink allow them to perform their duties, and high-quality color image output speeds are improved. With the addition of six-color inks, the ability of the printer to describe the transition level of color is also greatly enhanced. For example, in the description of a small magenta ink droplet, slowly turning into a dense light ink droplet, gradually adding medium light ink droplets, large light ink droplets, and then transitioning to deep magenta ink droplets. Finally, deep magenta ink Drop-based, such a variety of output combinations to soften the natural color of the printed image, even the dreaded character skin color reproduction can also cope with ease. Also, you don't have to worry about the dark areas being rough with large drops. The printer will add some small droplets and light drops in the dark areas so that the entire printout is equally good.

Fast dry ink

All models including the EPSON STYLUS RPO 10000 use EPSON's unique fast-drying ink, which has a strong penetration ability and can be quickly dispersed into paper fibers. It can be quickly dried (can be dried in 10 microseconds), and the appropriate diffusion also makes the ink dots merge with each other, the color performance is more natural, and it will not form too obvious graininess. This ink technology of EPSON is not available to other manufacturers. Comparable.

Century color pigment ink

In order to keep the print works without discoloration for a long time, it is necessary to make the color components in the ink resistant to light. The general dye-based inks cannot tolerate light, especially the long-term irradiation of ultraviolet rays in sunlight. So many manufacturers use a "pigment" type ink, which is composed of a large number of pigment particles suspended in water has a strong light and water resistance, but this ink also has a fatal flaw - the color performance is unsatisfactory. Century's color pigment ink successfully solved the contradiction between light resistance, water resistance and color performance using capsule technology. EPSON's lightfast pigment ink contains a large number of pigment particles, a layer of resin on the outside, forming a special "capsule". Due to resin encapsulation, the particles in the ink are only 0.1 micron, which is 1/100 of the general pigment ink particles. In addition, since the resin can reflect the ultraviolet rays in the sunlight, the color life of the printed work is further prolonged. Moreover, due to the wrapping of the resin, the pigment is also in contact with the outside world, not only the surface of the printed work is increased in the degree of finish, but also the printing is increased. Water resistance of the work.

This "capsule" technology also allows printed works to present the best image quality. General dye inks are formed on the surface of printing media due to the accumulation of pigment particles, forming a “diffuse reflection” layer that is uneven, which reduces the ability to express the color of the printed work. Therefore, the works printed using general pigment inks are either in the color gamut or the screen. The levels are far less than the performance of dye inks. The PSON lightfast pigment ink droplets are only 1/100 of the general pigment ink, making the picture very delicate; because EPSON light color ink droplets will infiltrate into the print media, and the pigment resin will fuse with other pigments outside the resin and form a smooth The surface layer of the screen makes the reflection of the light reflect the correct pattern, so that the quality of the entire print screen is the same as that of the image printed with dye ink.

The test is based on the light-resistant experimental environment provided by EPSON (without industrial exhaust gas, high-concentration ozone, etc.) and must be implemented in conjunction with EPSON special printing media. The test data shows that the EPSON image is extremely lightfast, but the specific data will vary with the environment. Therefore, it is recommended to use a film to save the picture to isolate the industrial exhaust gas, moisture and ozone.
