1, the technical level
CTP technology application is the most basic level, the technical level is also the most.First, we need to know the main cost of printing film depends on the price of silver, in recent years, silver rising from $10 / oz to 48 dollars an ounce.But the price of CTP plate in the opposite direction over the past two years, nearly half price.Why is the price of CTP plate and printing film in different prices?Mainly because the CTP plate of supply market competition.Next we are going to consider violet laser and infrared thermal, two kinds of technology have their own advantages.Packaging and commercial printing user to thermal CTP system is preferred;Large-format packaging printing user only thermal CTP system optional;Predominantly commercial rotary printing books and periodicals printing or the user can consider violet laser CTP system, on the use cost and printing performance, violet laser plate have more advantages;Newspapers printed user is advised to choose a violet laser CTP system, makes the purple laser CTP system in terms of speed and stability for a newspaper printing provides a solid guarantee production.Finally, we want to consider how to configure, CTP is no longer a single hardware devices, is the pronoun of a system, including direct plate maker, digital workflow, CTP plate and digital proofing, etc.The current mainstream workflow is based on the server - client "model, the underlying the database support. Software adopts the modular function, allows users to choose their own need to function, and the follow-up system development platform, or add functionality is very convenient. A typical digital workflow can contain the following functions: PDF conversion, and network technology, management, output devices support curves and puzzle, trap, CID fonts, compensation, color management, printing ink technology, digital proofing, network interfaces, CIP3 / CIP4 printing.
2, tactical level,
Application of CTP, solve the two problems, first is the quality control of CTP plate making, compared with traditional typesetting films, film printing process, the quality control of CTP plate making to make people feel relaxed and cheerful, as long as make the plate maker laser set according to the sensitivity of plate material, regular maintenance plate machine according to the requirements, success was 50%.And the other 50% is in the digital workflow of three kinds of calibration curve (linear curve, increase network plate, printing simulation curve).To precisely control the plate quality, the network density meter and print density meter is required, senior densimeter can set of printing network and print outlets and density measurement.For some plate system, also need to monitor the conductivity of the developer and pH value.The second is the CTP plate making cost control.CTP finally is green, the so-called green CTP plate is in the waste liquid discharge and water consumption in relation to traditional CTP plate materials have significantly improved.But for the printing, environmental protection is not the most important, printing eligibility of plate material, whether it is suitable for printing and the use cost is low enough is the most important, if the two problems solved, at the same time environmental protection plate is can use, fully compatible with the existing system, green CTP is "ready".The forecast is not far away, at least on the newspaper printing application, agfa violet laser from chemical processing plate completely conform to the requirements of the above, and around the world, there are also many domestic major newspaper to newspaper production switch to the environmental protection plate plate making.
Increasingly brutal competition in the industry, small profit, enterprise merger and reorganization, the moment, only the timely introduction of advanced technology, to the enterprise bigger and stronger, to survive in the market environment, today we introduce and use CTP technology is well lays the foundation for the future development of the enterprise.
