The size of ink droplets is the key to improving the quality of digital images because it directly affects the "graininess" of digital images, which is an insurmountable technical obstacle for traditional silver salt technology. The plate-making machine can achieve 6 picolitres (1 picoliter = 10-9 milliliters) of ink droplets, not only reducing the "graininess" of the ink, but also drying more quickly, regardless of black and white or color graphics, making it more detailed The color is softer, the layers are richer, and the texture is stronger.
(2) Intelligent drop conversion technology:
By adjusting the signal size of the transistor to control the volume of ink droplets, three types of ink droplets, large, medium, and small, can be produced simultaneously in one printing process, ensuring high resolution of 1440 dpi, uniform color transition, reduced nozzle use efficiency, and improved drawing. speed.
(3) Micro Piezo technology uses piezoelectric vibration of Japan to stimulate the ink droplets to fly out of the nozzle to control the size, shape and flight direction of the ink droplet. Behind the orifice of the micro-piezo print head is a spray capsule. Behind the spray capsule is a piezoelectric crystal plate. When a small and large voltage is applied to both ends of the capsule, it will be extended and contracted, and the printed signal can be used. The electrical pulse drives the crystal to contract the ejected ink. At the same time, the use of flexibility to control the ink droplet size, shape, flight status. Through intelligent droplet conversion, large ink droplets are composed of medium and small ink droplets, thus avoiding defects such as star-shaped and fog-like scattering due to ink tension due to ink tension. Therefore, the fine grain, high resolution, sharp outline, sharp image, and clear image are more suitable for the Chinese character's cross stroke reproduction.
(4) 6-color quick-drying ink:
Combines 6 colors of quick-drying inks of cyan, magenta, yellow, black, light blue, and light magenta with the tonal adjustment technology in fine images. The use of photo-screen printing principles combined with three-dimensional fast calculation tables and error diffusion technology enables unprecedented improvement in color reproduction. Enhanced color performance.
2, special printing software Chinese operation interface, suitable for Windows95/98/NT, Mac platform, support network capabilities, is fully compatible with Postscript Levedll, and is compatible with Peking University Founder typesetting system, can be issued directly on Apple and the PC a variety of software production Layout, PageMaker, FreeHand, Quarkpress, Illustrator, CorelDraw, Word, Founder Feiteng, and Wes.
The printing software has a good and feasible data interface, simple operation, high quality screening (up to 175 lines), powerful and comprehensive, fast interpretation and task queues, imposition, preview and other functions. When large-format output is available, the film width and layout width can also be automatically calculated, output in the most provincial way, and the small version can be automatically converted into large-scale output, and the imposition layout can also be manually controlled.
3, special consumables:
Dedicated CTP film and PS plate are coated with special treatment.
Advantages and disadvantages:
The CTP system adopts a new concept of physical imaging technology to completely get rid of laser generation and the use of photosensitive materials. It uses ink jet equipment to directly print out the required graphics and text on film, paper, and PS layouts, reducing the number of image transitions. 100% transfer, no content loss, ... large format, no need for imposition, revision.
Using the same principle as the laser image-setter, regardless of platform type, external drum, or internal drum type equipment, computer-controlled laser beam scanning exposure imaging is used, and then the plate is formed by processes such as development and fixing. It can also be said to be The laser image-setter, developing and fixing equipment and the plate-making machine are integrated.
According to the materials and structural features of the plates, the CTP plates currently used abroad can be classified into photosensitive resin plates, silver salt composite high-speed PS plates, aluminum-based silver salt platen plates, thermal plates, and photoconductor plates. Imaging large quantities is still not free from photochemical imaging routines, but also with a series of kits. Thermal plates and photoconductor plates require laser generators that use laser thermal effects. These plates are expensive and require high-resolution, high-sensitivity and high-intensity guarantees. The domestic market is still unable to achieve localization. It takes a long time to promote cooperation.
