FIT positive thermal CTP: new choice of media

With the increase in the volume of direct plate-making equipment, the demand for the domestic CTP plate material market has also continued to expand as a consumable item matching with direct plate-making equipment. At present, most of the plates used by domestic CTP users are imported plates or plates produced by international manufacturers in China. In order to meet the market development needs of CTP media, Sichuan Juguang Printing Equipment Co., Ltd. cooperated with the original CREO company in 2004 to develop and introduce the JPT-1 positive thermal CTP plate, which was not achieved in 2005 and 2006. Vulgar achievements, the domestic market share has reached more than 20%.

In October of this year, Chengdu Xintu Printing Technology Co., Ltd. has officially launched the FIT positive heat-sensitive CTP plate with independent intellectual property rights, which promotes the development of CTP plate material technology in China and makes the domestic heat-sensitive CTP plate material. The performance and quality have reached the level of world-class products, so that domestic users have more choices.

FIT is a new generation of positive-acting thermal CTP plate. It can be widely used in all 830nm thermal plate-making equipments in the market including CTP. It can meet the fine screening requirements of up to 450L pi, perfect reproduction 1% ~ 99% of the dots have reliable plate-making stability and ideal ink-water balance, and have good chemical resistance, scratch resistance, and high resistance to printing.

Fast plate making

Because the exposure energy required by the FIT is only 120mJ/cm2, the platemaking equipment can choose to perform exposure imaging at a higher speed without changing the power of the laser head, thereby increasing the platemaking efficiency and effectively maximizing the production capacity of the device. At the same time, FIT is not only suitable for commercial printing but also suitable for newspaper printing because of its low exposure energy, high resistance to printing and strong stability.

Network restore accurate

Because of the highly directional nature of the laser, the reproducibility of the printing plate dots output by the CTP depends mainly on the thermal characteristics of the photosensitive layer. FIT without any curve, the dot output error is about 0.5%, the linear performance is very good, to ensure the accurate reproduction of graphic color in the printing process. FIT adopts an innovative production process to form a unique sand layer structure and innovative hydrophilic coating on the surface of the plate base, which makes it have excellent hydrophilicity and water storage performance, and the water volume can be reduced by 30 when compared with traditional plates. From 5% to 50%, water and ink can quickly reach equilibrium, reducing the complexity of print production and increasing production efficiency.

Good development stability

Due to the constant consumption during the development process and the loss of natural oxidation, the development efficiency of the developer gradually decreases, and the stability of the development process often becomes a major shortcoming in the consistency of the plate making. FIT boldly changed the traditional practices of the same formulation of common replenisher and developer, and revolutionized the replenisher solution, eventually finding an effective solution: use DV-F as developer and DV-FR as replenisher. Experiments have shown that this solution can effectively improve the fatigue of the developer, improve the stability and reliability of the development process, and help to obtain a consistent plate-making effect. Experiments have shown that after replacing the developer solution, 2500 to 3000 square meters of plate material can be continuously developed, which greatly reduces the cost of using CTP.

High-resistance force

Due to the outstanding chemical resistance and abrasion resistance of the sensitized coating, the FIT's operating tolerance is extremely high and it is easy to obtain high resistance to printing. It can print up to 250,000 impressions when it is not baked, up to 1 million impressions when it is baked, and apply to UV inks after baking.

The R&D of FIT is based on meeting the mainstream needs of most CTP users, with a more balanced and perfect overall performance, which can meet the needs of the vast majority of printers. For example, NO DICA is a book printing company located in Panyu, Guangdong Province. The company owns 3 SCREEN direct plate making equipment and more than 20 various printing presses. As the volume of business continues to increase, the printing department hopes to have a high-sensitivity, high-resistance thermal print, which will increase publishing efficiency and output more printing plates at the same time to meet the increasing production demand. The plate is just such an excellent digital version. With the use of FIT media, the output of the media has increased by more than 20%, which has greatly eased the pressure of the prepress department. At the same time, due to the high printing power of FIT, the probability of making up the plate is also greatly reduced.

The launch of FIT has made up for the inadequacies of the original JPT-1 product and placed the quality of the domestically produced CTP plate on the same starting line with international brand products. Allows users to have newer, more and better choices on thermal CTP plates. Links Chengdu Xintu Printing Technology Co., Ltd. is a modern enterprise specializing in R&D and production of CTP plates and technical services. Its headquarters is located in Xindu Industrial Development Zone, Chengdu, Sichuan Province. Its international advanced level automatic thermal-type CTP plate production line was put into production at the end of October 2006. The speed is 30 meters per minute and can produce plates with a width of 1500m or less. This production line represents the most advanced CTP media manufacturing technology and management methods. All production process processes are fully automated. Automatic on-line inspection and automatic slitting technology make the error caused by manual operation zero. The annual production capacity of the production line exceeds 1000. Ten thousand square meters.
