With the continuous networking and digitization of printing technology, digital offset printing has begun to spread at home and abroad, and a new type of ink-electronic ink suitable for digital offset printing presses has been used. Electronic inks contain charged liquid ink particles that enable electronically controlled printing of the position of the particles in digital printing. Electronic inks can reach very small particles (1 micron to 2 microns), so small particles enable printing to achieve higher resolution and smoothness, sharpening the edges of the image, resulting in a very thin image layer. Electronic inks have now played a role in the following areas.
(1) Standard basic color CMYK;
(2) The six-color setting of the wide color gamut adds orange red and purple, which makes the color reproduction ability much higher than the color reproduction ability based on the original four colors;
(3) Pantone compatible Indigo spot color system;
(4) an opaque white coating of a colorless substrate;
(5) Fluorescent ink. Indigo's color digital offset presses offer a unique combination of features, all using electronic inks (ie Indigo's unique liquid inks).
Electronic inks generally have the following advantages:
(1) High brightness, high definition and durability. Manufacturers use the same ingredients as traditional inks, but only charged inks to make electronic inks. Therefore, electronic inks are similar to those traditionally printed on paper, but the brightness and contrast are high when matched with paper. And can have a 180 degree viewing angle.
(2) Low energy consumption. Once the white paint particles are driven to a state where an image has appeared, the image may disappear (because there is no additional energy support), but this does not exist for electronic inks.
(3) Strong printability. Electronic inks are suitable for almost all materials and can be printed on textiles, paper, plastics and many other materials. We know that the LCD display is displayed on the glass, but it is heavy and brittle. Electronic inks can be displayed on plastic surfaces, making them ultra-thin, flexible and not fragile. Electronic ink is an ink. If someone walks into the laboratory and accidentally is splashed by electronic ink, then this person becomes a walking monitor.
Printing with electronic ink is very easy. For example: it can be used for web printing, and it is estimated that it will be used for glossy advertising paper and other large-format labels in the near future. Today, electronic inks are beginning to work with other electronic devices. For example, e-ink recently announced that it will work with ibm to develop a world-class svga-type electronic ink display. It is estimated that electronic ink-based displays may be put on the market in the last year or two. Electronic inks are also said to be in line with the emerging revolutions in the publishing industry in the field of printed electronics. Here, e-ink and lucenttechnologies have produced the world's first fully printed display. Their ultimate goal is to print on one sheet of paper with one side and electronic ink on the other.
