As the general agent of the ECRM direct platemaking equipment, Beijing Top Best Commercial Machinery Co., Ltd. has accumulated some experience through the use of the ECRM direct plate system and the printing press. The following describes some of the experiences in use.
Mako 5625 direct polyester system is a CTP system developed by ECRM in order to meet the requirements of fast printing. It has a unique double bar positioning design to achieve simple switching between output polyester and output films, enabling users to The actual situation is flexible and work. The system can be perfectly combined with various high-speed printers, which can fully reflect the fast and efficient printing speed.
The plate we use is Silver Digiplate SDP-FR175. The thickness of the plate is 0.2mm. The resistance force can guarantee 30,000-50,000 prints. The specific print volume depends on the printing conditions at that time. set. In order to ensure the correct reproduction of the outlets, the first step is to adjust the output printing plate. Morality guarantees the correct exposure intensity of the Mako 5625 plate-making machine under the premise of ensuring that the conditions of the stencil processing conditions such as the development temperature and the plate-making speed are relatively stable. If the exposure intensity is too high, the output dots will be reduced. After the image becomes lighter, text lines may break. If the exposure intensity is too small, the output dot will increase, and the printed image will become dark. The text lines may be blurred and unclear. After a specific method is used to determine the correct exposure value, the linear adjustment of the printing plate is performed. The purpose is to keep the size of the output printing plate's internet point in line with the actual expectation. With the calibrated curve output plate, the dot reproducibility is very good, 1% to 99% of the dots can be accurately produced, and the error of the intermediate tone is less than 2%. Special attention should be paid to the fact that the linearized data of the plate is relative. Changes in the linear parameters, such as changing the plate or developer, the aging of the laser, and the long-term use of the liquid, may require adjustments. The second step is the printing on the polyester plate. Installing the machine version is the most critical part of ensuring multi-color printing and overprinting. Because the tensile strength of polyester plates is different from that of traditional PS plates, it is very important to choose the correct printing method. Many advanced multi-color printing presses are equipped with an automated plate-making device, and overprinting of prints is very accurate. If you hand on the plate, you need to master certain operating methods to adjust the tension. Having mastered the standardized installation procedure, the use of polyester plates will be very convenient and quick. If a special liner is used, the friction between the polyester plate and the plate cylinder can also be increased. In addition, special methods are used to compound the polyester plate with the PS plate, and the stretching can be reduced by the toughness of the PS plate, but the printing pressure must be fully taken into consideration. The pressure is too large to cause dot enlargement, and the color of the printed matter is distorted. . Mitsubishi also provides a quick-to-print mechanism SLM-QM||| for polyester printing, which can be installed on a variety of presses to accurately position, quickly replace plates, and shorten preparation time. Japanese RYOB|(Ryobi) Company has added “platen tension adjustment device†to the latest version of the plate to better adapt its printing press to the printing of the polyester plate, and designed two versions of the metal plate and polyester plate. The dampening cycle mode greatly improves the adaptability of the printing press. Pay special attention to the fact that when installing a polyester plate, do not wet the back of the plate. If there is water on the back, when adjusting the overprint, the plate will not move smoothly, it will be difficult to register the image on the plate, and even cause the damage of the plate. When using polyacid printing, the hydrophilic and ink-receptive properties of the printing plate are very good, whether it is using ordinary fountain solution or alcohol, so that the ink balance is easily grasped in the actual printing process. When using Mitsubishi silver salt digital printing, it is also possible to use its recommended SLM-OD50 for dampening, which can fully surface the non-graphical surface tension of the plate, enhance the hygroscopicity of the plate, and thus improve the printing conditions. ensure product quality.
In addition, ECRM's Wildcat and Tigercat direct plate systems are the best choice for large-scale publishing and commercial printing. The Tiger Tiger Leopard direct plate system can directly output four-up and above format plates, with a maximum size of 618mm x 820mm. It chose ECRM's patented holographic imaging technology and a new internal drum structure, with a maximum output resolution of 3556 dpi, which can fully guarantee high quality to degrade the output. The system can be continuously printed by the supply box or automatic plate feeding mechanism, connected with the corresponding plate processor, and integrated into the digital workflow. The red light, green light or violet laser can be selected according to the actual situation of the user, so that the system can adapt to different Types of plates.
In addition, the Weibo Direct Plate System also increases the output width to 648mm x 914mm. With dual exposure system, the output speed can reach 240 sheets/hour at 1000 dpi, which is very suitable for newspapers, presses, etc. to meet the needs of fast output printing plates.
In order to meet the requirements of large-scale commercial printing, ECRM has introduced the Desertcat 88 large-spread thermal plate direct-working system, with an output size of up to 1130mm x 900mm. The system uses thermal imaging technology, external drum structure, the use of advanced multi-speed infrared laser thermal laser head, printing plate fixed on the outer drum wall, the use of positioning lock trapping system to ensure that different types, different thickness of the plate are Can easily image, repeatability of 0.005mm. In addition to the ability to output plates, it can also output digital imposition thermal proofs, allowing users to get the highest returns with lower investment. The system is hosted by an effective workflow system and is flexible and reliable. It is a value-for-money, off-line, direct-to-plate system. (From "Printing Technology" 2001 2)
