The principle and use of color laser transfer technology (on)

Color laser transfer technology is actually born and developed with the progress of electronic computers and their peripheral output technologies. Thanks to the fast and powerful processing capabilities of computer graphics software for images and texts, MacIntoy's color laser transfer system is becoming more and more popular due to its convenient and fast processing technology, vivid color performance and convincing high quality. s concern.

To meet the requests of readers, the following briefly describes the basic principles of color laser transfer technology, application in the screen printing industry, color laser transfer paper types and application methods, product quality characteristics and traditional screen printing And the comparison of inkjet printing process, at the same time roughly talk about the application of this technology in textile printing, sign advertising, gift production and other related industries.

â—† Process characteristics of color laser thermal transfer printing:

1. The printing quality is exquisite: The color laser printer adopts the most advanced digital electrostatic imaging technology at present, wide color gamut, fast printing speed, natural color transition, true reduction, vivid color of the image.

1) Using integrated circuits to handle data compression, RGB to CMYK color conversion, and intermediate color transitions, ensuring fast and accurate color reproduction.

2) Precise ink dot control technology can raise the effective resolution to 2400dpi, (generally A3 format color laser printers of around 3,500 yuan now basically reach a high resolution of 2400dpi), thus ensuring unmatched image quality .

3) Through the computer software's resolution enhancement, automatic color correction and other technologies, even a complex combination of images and text can ensure high-quality output.

2. No need for plate making, fast and intuitive: No need for complicated prepress processing, as long as there are computer files, finished products can be seen in minutes, high-speed color laser printers can even print 60 pages per minute, high speed and high reliability can achieve true significance It is desirable and industrialized.

3. Good color fastness and easy operation:

1) Textile Printing: Color laser transfer is actually the penetration of tiny carbon powder particles with a diameter of only 5.8 μm into the interior of plant fibers through high-pressure thermal transfer. For this reason, the surface of the textile printing surface is invisible, breathable, and the colors are firm. Good degree. Laser transfer simulates traditional printing, but unlike traditional printing, it can produce high-definition that cannot be achieved by traditional screen printing, and the image details are more outstanding.

2) Metal plates and other hard materials: Due to the tiny particles of carbon powder penetrated into the recessed part of the metal surface (the recessed part can be actually seen on a flat metal surface under a high power microscope), plus laser printer toner It contains a special hot-melt resin, which ensures that the color fastness of the image is ensured by the combination of the toner particles infiltrated into the depression of the metal and the toner particles on the metal surface by hot pressing. The results of tests on metal business cards and similar metal plates demonstrate that laser transfer images have better color fastness than other printing processes. One hundred observations are not as good as ones. Interested parties are welcome to contact McGinty for samples.

4. Low operating cost: In a certain amount of range, its price has considerable advantages, and because there is no need for complicated prepress processing such as film making and equipment debugging, the pre-press processing cost and personnel costs saved are also very low. Appreciable, at the same time, with the increase in the number of production laser transfer paper and printing toner costs can get a larger number of discounts.
