Ion deposition printing technology uses and advantages

Ion deposition printing technology is a high-speed, high-quality, pressureless printing technology used to print a variety of data on labels and trademarks—serial numbers and codes. This ion-pumped pressureless printing device is integrated with a standard narrow-web label printing machine to produce a color trademark with various information data. Printed trademark products can take a variety of forms, such as folding, photo book, leaflets or reels.

Has many uses

Ion deposition printers can actually produce any image and print a wide range of bar code symbols. The size of the bar code can be varied, and its density and height can also be determined according to the user's requirements to meet the requirements of manual scanning and high-speed full-scale scanning. The operator can arbitrarily set the bar code size, as small as 1/10 inch, as large as a few inches. The printer can also print sequence numbers, using digital, alphanumeric or alphanumeric specifications. It can also print irregular data from the tape, as well as any decimal digits and other miscellaneous information. The ion deposition printer can provide text in various sizes and fonts, such as readable alphanumeric text including the text of the optical reader (OCR`A). The programmer of the aircraft can even design special fonts or copy pattern graphics (such as logos and drawings, etc.) requested by customers. The printing direction can be parallel or vertical.

In order to meet various environmental requirements in the industry, ion-deposition printing can be printed on paper, and can also be printed on polyester film and polyethylene film. These plastic surfaces are resistant to water, heat and long-term durability. Using these materials with high-performance glue, users of ion deposition printers can produce durable labels that, when combined with light or lamination, increase label life.

Ion-deposited printed bar code labels and hangtags are used in a wide range of applications in industry, in government departments, universities and various institutions. Ion-deposited printed labels are used for assembly inspection and tracking in automated assembly plants; high-speed sorting systems use them to track classified bodies; libraries use them to identify books; computer makers attach it to computer hardware for numbering, etc. In short, users of all walks of life can use this ion-deposited printed label according to their own needs.

Ion deposition printing technology

Ion deposition printing is a branch based on color technology. In the mid-1970s, it was generally welcomed by securities manufacturers. This basic technology was developed as part of a research project to improve the performance of copiers. This ion deposition printing technology is characterized by using a non-conductive roller, the roller image is partially charged, the non-image part is not charged, and the charged part of the image is charged with toner after charging, and the toner is retransferred on the printing material. This printing method is basically the same as other printing methods such as electrostatic printing, magnetic printing, and laser printing. However, the ion deposition printing technique still has its own characteristics. It uses ions, actual charged particles, and selectively charges the drum. These ions are generated in a device that is much like a printed circuit board. This device has a number of holes through which ions pass and the computer controlling the imaging process determines which holes the ions come out of. Under the control of a computer, when the ions are projected onto a non-conducting roller that rotates underneath the device, a variety of desired images, such as letters, symbols, or bar codes, begin to form. At the beginning, the ions landed on the roller, forming a latent image that was invisible to the naked eye because no colorant was used. To make the latent image visible, toner must be used. The differential of the electrostatic field causes the toner to fall on the charged image. Charged toner particles form a static brush against a toner roll. This roller uses electrostatic attraction to suck charged electrostatic particles from the image. The aluminum roller with latent ion latent image also forms an electrostatic field whose magnetic field is stronger than the magnetic field formed by the colorant. The non-conductive roller rotates through the toner roller. The passed ions have a suction force that is greater than the suction inside the toner roll, so that the toner "jumps" from the toner roll onto the non-conductive roll and adheres to the latent image by electrostatic force.

Prepare for printing

Once the image is visible, it can be printed. When the non-conductive roller is rotated with a visible image to a point of contact with the running label web, the web is squeezed together with the pressure roller, the image is melted onto the web material by pressure, and then the image is taken The web is ejected from the ion deposition printer onto the label printer.

Ion deposition printing press is a relatively simple printing technology. Charged ions pass through the electrostatic field and are drawn into the non-conductive drum as latent images. As the latent image is electrostatically charged, charged toner particles "jump" from the toner roll onto the roll, producing a visible image. The press roller presses the image onto the paper. The bar and the neutralizer clean the roller and continue printing.

In order to repeat the printing process, any residual powder and charged ionic particles must be removed from the drum surface. Therefore, when the drum continues to rotate through a fixed scraper, a small amount of residual toner is scraped off so that they do not remain on the subsequent web. After the drum is cleaned, the non-conductive drum is held underneath. By passing, the crowbar continuously generates a magnetic field that neutralizes any residual charge remaining on the drum surface. This process is to remove the electronic image from the roller and prepare for the next printing. Non-conducting rollers can perform various different functions of ion deposition printing at different points of their rotation, enabling the printing process to continue and print at high speed.

The mechanical characteristics of the ion printer are simple. In fact, only the non-conductive roller and its opposing pressure roller are the moving parts that rotate on the bearing, smooth and continuous. This greatly reduces mechanical wear and maintenance costs. Since the operation is performed at a high speed, most ion printers use pressure melting method to press the toner image onto a web to fuse the toner, just like an office copier, so that the web reaches the temperature of the hot melt. , It is bound to greatly increase the length of the hot melt device, or increase the thermal radiation of the thermal fuse voltage. Today, ion deposition printing presses have a print resolution of 200-300 dots per inch. This type of resolving power results in a fairly smooth printing curve. The printing characteristics correspond to desktop laser printers. From an aesthetic point of view, the print quality is not as high as offset printing, but the printing characteristics far exceed the electronic computer-driven printing devices that appeared a few years ago.

The advantages of ion deposition printing

Each basic characteristic of ion deposition printing is beneficial to the user: the simple mechanical structure is conducive to the reliability of ion deposition printing machine manufacturing; low operating cost, long service life, and inherent operating speed, enabling users to produce more per hour Many labels and trademarks reduce the processing costs of prints.
The response speed of the ion deposition printing box, regardless of the combination of black and white dot printing, keeps the machine operating speed constant. From a practical point of view, the operation speed is unchanged from the beginning to the end when performing such stepped and pointed bar-coded bar code printing. of.

Of course, the speed of ion deposition printing also has variable capabilities. Due to its flexible speed, this ion deposition printing technology is more suitable for on-line operation with other devices than other printing technologies. When used on a label printer, ion deposition printers provide greater flexibility, and the web runs as soon as the web starts to run.

Ion deposition toners are based on carbon and are excellent pigments for bar code printing. Carbon absorbs light from the white and infrared spectrums, which means that the barcode produced by the ion deposition method will provide the appropriate print contrast regardless of which scanner is reading.

Every use of a new technology will always bring a good opportunity from the user's economic point of view. For users who produce a large number of trademarks, it is generally possible to make a profit of 20%. However, when a variety of information on ion deposition images is printed on a trademark, the gross profit can reach 35%.
