The advantages of CTP technology and its application in color printing and newspaper industry

Ntent > Since Drupa 1995 , CTP technology has become one of the hottest topics in the field of printing. “ CTP is a professional vocabulary that has also appeared on the print media. With the enthusiasm of many technical experts, the popularity of CTP equipment in foreign countries has increased. Infected, the domestic printing industry has also set off an upsurge in the purchase of CTP equipment. However, due to the high cost of investment and the uneven effect it brings to various printing companies, we have to calm down and think about it. At this stage , the scope of application of CTP technology is the application of CTP technology in a certain period of time in order to exert its greatest advantage.

Normal >      The advantages of CTP technology

Normal > CTP technology has the following advantages over traditional platemaking processes :

Normal > 1 . Good print quality

Normal > Because CTP technology no longer uses film, but directly through the optical energy or thermal energy rendering on the plate, so the dots on the plate is a direct imaging site, eliminating the film factor and dust Platemaking defects are cleaner and clearer than those on ordinary PS plates. At the same time, due to the reduction of processes, many variables in the platemaking process, such as film development, exposure, and chemical development drugs, are avoided. This also makes the possibility of human errors in the process of plate making greatly reduced, and the stability is much better than the ordinary PS version. In addition, CTP technology uses a more accurate plate positioning technology, eliminating the manual imposition error, the completion of the four-color version of the repositioning accuracy up to micron level, the print adjustment error in the print is almost negligible. Visible, CTP technology will inevitably improve the printing quality.

Normal > 2 . Shorten production cycle and save labor costs

Normal > The traditional plate-making process takes 40 minutes from taking the film to the printing plate , especially when the plate is more concentrated, the time required is longer, and the situation such as the printing machine is often appeared. The CTP technology can generally preview, put together a large version ( collage the layout required by customers ) , through the optical energy or thermal energy directly on the plate material imaging, thus eliminating the need to take film, manual imposition, printing and other processes. It takes only a minute or two to fight a four-color version of the four-color version, and it takes only about 10 minutes to output a four-color version , which saves nearly 30 minutes compared to the traditional plate-making process . This avoids the need for a printing press in the traditional platemaking process. phenomenon. In addition, the preparation time for printing and the cost of preprinted paper and ink can be greatly reduced.

Normal > 3 . Remote copying can be done to achieve on-demand printing

Normal > The Internet as a business tool that connects printing plants with customers and suppliers to complete sales. Distributing prints, managing print production and ordering consumables. There are many printers now have network connectivity and use e-mail for business contacts. Some also set up their own web pages. CTP technology fully adopts digital process flow, which provides convenient conditions for offsite printing of web uploads. Moreover, CTP can achieve " RIP
