CTP and digital printing

CTP and digital printing are trends in the printing industry. If commercial printing companies do not have plans to develop these technologies, they will feel powerless in the future. Large printing companies that have substantial funds have begun to use digital technology, first R&D mode, and then gradually expand to various operating areas. For medium-scale printing companies to invest in new technologies, they must rely on two aspects: capital and technical skills. For these companies, the price of CTP is quite high, and they usually consider investing in printing presses first. In terms of technology, printers with prepress experience will be able to master the most front-end technologies such as CTP, FM network and high-fidelity color.
Small print companies can invest in CTP systems using polyester versions (such as Agfa's SetPrint), which can use existing laser imagesetters and workflows, such as Agfa's Select Plate. The marketing strategy for such companies is to produce short-duration monochrome, spot, and four-color prints.
For different print markets, printing companies must have different business ideas. We can analyze one or two markets: If magazines print, each magazine company wants to receive a lot of advertisements. Because they use a desktop publishing system to typeset, they are required to allow print companies to allow them to modify the layout at the last minute to accommodate later-added advertisements. Due to the high circulation of magazines, the tight production time, the number of periodicals, and the high requirements for color and printing quality, it is most appropriate to use the CTP digital production system for production. However, they need to purchase a copydot scanner to digitize their advertising advertising film.
Just relying on quality and price to please customers is not enough. What the printing company needs to do is:
First, establish and maintain long-term partnerships with customers. The current all-digital workflow provides opportunities for printing companies and customers to maintain relationships.
Second, understand the customer's business and needs, so that they can continue to provide them with new services.
Third, learn how to promote companies and services so that they stand out from their competitors.
Digitization is a goal that must be achieved, but everyone takes a different path. There are many details that need to be dealt with in the digital workflow. It is necessary to strengthen the communication between the various departments within the company and customers in order to avoid the problems that hinder production.
In CTP and digital printing workflows, the cost of error rework is quite high. If the problem occurs in operation, the operator needs to be trained; if the customer's file is in trouble, prepress preflight and faults need to be strengthened. Repair features and strengthen customer training.
For jobs with a large number of images, the printing company needs to use the OPI server. OPI can reduce congestion on the network and increase production. In page layout, low-resolution image avatars can be used, while high-resolution images can be edited on another work platform. In the final output process, high-resolution images replace the image avatars.
Further, commercial printing companies can use Adobe's PDF and PDF-based workflows such as Agfa's Epson workflow to streamline the prepress workflow. PDF is a file format that includes all font images, etc., independent of the operating platform, it can solve a series of problems of prepress preflight. Once the file is “distilled” into PDF by Postscript, the raster processor can perform fast and efficient raster processing and screening of the file. Each page of the PDF file is independent, so a problem with one page does not affect other pages. Using a workflow similar to Agfa's Epson, its multi-output function for one raster processing ensures the consistency of digital proofing and printed matter, and the Epson workflow can automatically carry out large-scale printing and trapping, improving Printing company's efficiency.
Using appropriate proofing equipment for proofing can reduce costs and save time. If the production volume is large, digital proofing can be used to reduce intermediate links such as film and syrup. The selection of digital proofing equipment will directly affect printing costs and production.
For short-run or medium-volume printing, the printing company can use polyester version of the CTP, up to 15,000, which is the most economical direct plate-making method. If prints that are frequently printed are demanding and are long prints, then consider installing a metal platesetter, such as Agfa's Galileo, which can output 21 32.29 x 44.5" per hour ( 2400dpi) media, to ensure that multiple printers can print at the same time.
