2. Ink-jet printing
Since the fifties of the 20th century, the development of inkjet printing by the American ABDick company has been smooth, and it has become a famous brand in printing technology. According to a survey in Japan, it occupies about 12% of the market without prints.
Inkjet printing is generally divided into continuous jet mode, intermittent jet mode, on-demand jet mode, etc. It is directly connected with the computer to solve high-speed, small-batch printing and on-demand printing, because it is a non-contact printing method. Printing on a three-dimensional object is its greatest merit.
Furthermore, most of the equipment for inkjet printing is provided for office work and household occupation. In the future, it is estimated that in addition to expanding in these areas, there will be corresponding growth in the printing department. When the printing department is currently divided into general printing (less than 72 inches wide) and industrial printing (more than 72 inches or more), it is considered that there is a possibility of expansion in the industrial printing field.
For industrial printing, the new development of inkjet printing is UV inkjet printing. Large-scale UV printers have been manufactured in the UK. They can not only print at high speed and quality, but also print high-quality prints that rival ordinary printing. For this reason, pigment solvent-based inks and UV inks have been developed for use in response to applications.
Inkjet printing has been used in many printing companies for color proofing. It should be noted that if dye inks are used, dry back color is likely to occur, making color management difficult, so pigment inks have been used.
In short, today, in the 20th century, this type of ink-jet printing machine, which does not need printing plates and does not require printing pressure, has almost no noise, will be used as the fifth printing method to show its edge in the prosperous printing industry.
3. Electronic printing
Electronic printing is divided into electrophotographic printing (electroprinting, xerography), electrostatic printing, ionography (ionography).
At present, electrophotographic printing is the mainstream in non-printing. Its main means is to use powder to develop. It uses light energy to complete printing. The most famous is the electronic photocopier, whose commercial name is Xerox.
The principle is that on the positively charged photosensitive layer, the light is used to expose the original, and where the light contacts, the positive charge disappears, and the photosensitive layer is left uncharged by the light, and a negatively charged coloring is applied thereto. When the powder is scattered, the powder adheres to the positively charged portion of the photosensitive layer, which is brought into close contact with the paper, and a positive charge is applied from the back of the paper. After the powder is transferred onto the paper, it is heated or the solvent evaporates. Fixable paper finishes printing.
Electrostatic printing is different from electrophotographic printing in that it uses electric energy to complete its work. Its representative technology is facsimile. However, besides the currently widely used facsimile, there has been a large market demand for electrostatic gravure printing, which uses electric power to transfer powder through a screen to a printing material, and electrostatic gravure printing, which uses static electricity to increase gravure ink transfer. .
The ion discharge imaging method referred to here is, concisely speaking, a technique for selectively scanning an insulating material using an ion discharge device to form an electrostatic latent image. Specifically, a photosensitive plate is placed between the needle electrode and the planar electrode, and a gap is established. The size of the gap is very important and it relates to the sharpness of the image. When a high voltage is applied across the two electrodes, an ion discharge occurs, and a charged latent image can be formed on the surface of the insulating material. This is based on image data to form a latent image on which powder is dispensed and fixed onto paper for fixing. This type of technology is currently available for reprinters.
4. Heat transfer printing
Thermal transfer is divided into wax ink transfer and dye transfer. The dye transfer is further divided into a thermal transfer method and a sublimation thermal transfer method. The former rely on the transfer ribbon coated with a solid ink at room temperature, while the latter uses a transfer ribbon coated with a sublimation dye as an ink layer. Generally, a graphic-heating printing head is used to melt the wax ink or dye. To transfer images and texts to plain paper, the sublimation heat transfer method requires a large amount of thermal energy, and has been applied to the printing and dyeing of color printers and garments.
For example, the use of digitally-printed non-engraving printing has the charm of eliminating plate-making and non-emission of pollutants, protecting the environment, and eliminating the need for skilled operation techniques, leaving it to the future to cultivate good business practices. Salespersons and good publicity work.
In addition, according to the market environment for the needs of small-volume live and personalized printing, should pay attention to the expansion of variable data printing, users who pay attention to CRM (customer relationship management) to fully explain the various effects of variable data printing.
In short, with the rapid development of intelligence technology and the wide application of digital technology, it provides a wide range of development space for the printing industry with its flexible, rapid and high-quality reproduction effects. It also makes the competition in all fields of the industry even more fierce. How to meet different requirements and conduct full-service has become the focus of business operators. With the increasingly diversified and personalized market, the use of digital technology to personalize document data has become a general trend.
