Computer to Plate

CTP platesetter is the acronym for Computer to Plate , belonging to the computer -to-plate prepress equipment. The first CTP technology introduced by Kodak in 1995 , the Drupa 2000 exhibition , CTP technology has made a leap in technology is more mature , the device began to really enter the application phase.

2 classification

CTP platesetter generally divided into the drum , outer drum , flat , curved style of the four categories. In these four types, the most currently used within the drum and the outer drum ; wherein the relatively good performance of high-grade are used in CTP platesetters the outer drum .

CTP technology is sensitive thermal imaging technology and imaging technology , the most widely used and most stable performance is thermal imaging technology. Currently the most advanced and sophisticated CTP platesetter thermal imaging technology that Kodak introduced the " square spot " thermal imaging technology .

3 benefits

CTP platesetter significant advantage of four points to help enterprises to improve efficiency and effectiveness . ( A ) shorten makeready times , fully improve printing efficiency ; ( b) strengthening the network control to achieve quality printing ; (c ) reducing the plate links, while section effort to accelerate the delivery cycle ; ( d) strengthen workflow management

4 selection method

* examine the quality of CTP platesetter : on thermal, violet , plate quality CTcP outlets has been the focus of debate ; different workflow features, applications FM screening technology also has its advantages. Though. Through practice, the advantages of thermal platemaking has no doubt and, like Kodak thermal CTP machine "square spot " technology is currently the highest standards. But we also recommend the printing plant , the objective evaluation and appropriate comparison is necessary.

* investigate CTP machine capacity : printing printing equipment according to their capacity to select the speed , the speed of CTP platesetter platesetter is generally based on model, configuration is divided into different levels , the faster the machine , the higher the price . Do not blindly pursue platesetter speed, must be based on the actual situation of their own factories may be, can not play or buy back its efficacy , but also resulted in unnecessary waste. Of course, like the Kodak Trendsetter 800 series speed can be automatically upgraded, so this situation does not exist .

* see CTP production models can be upgraded : Select a model , the best equipment to enhance the speed of the plate version potential for future additions to the factory presses, speed platesetter can quickly adapt production requirements. Do not choose the platesetter can not be upgraded , can not be upgraded to the final , only to re- purchase a plate making machine , it is not worth it.

* Consider running costs: how much money to buy the machine , how many one-time investment, which is printing will consider and calculate things . So some manufacturers will consider options prices slightly lower machine type, but on the one hand , equipment prices are one-time investment , other investment is long-term operating costs , so the related products and supplies also can not be considered small . So the choice, not just look at price , but also to calculate the running cost comparison.
