CTcP is the English abbreviation of Computer To Conventional Plate, which refers to computer-to-conventional plate making on traditional PS plates. The basic imaging principle of the plate and the light source have basically not changed. The only requirement is that the UV-Setter is configured in the system. Most of the offset printing plates can be imaged using UV-Setter exposure. Just use digital micromirrors instead of film, and step-by-step seamless splicing area exposure to replace the one-time imaging of the entire format. It not only has the high quality and efficiency of CTP, but also retains the characteristics of easy operation and stable performance when printing on traditional plates.
The Unique advantages of UV CTP
(1) Significantly reduce pre-press production costs
- It is to simplify the technological process, reducing the traditional process of film production, manual imposition, printing and other processes, which can save consumables and related costs.
- it is suitable for any traditional PS plate, using conventional developing machine and processing chemicals,easy to operate in bright room conditions.
(2) Reduce printing debugging time and material loss
There is no need for plate positioning, and there is no need to re-make plates due to inaccurate positioning, avoid spending a lot of time correcting the plate during printing on the machine, minimize the time for short-run printing plate change and on-machine debugging, and reduce water, paper, and debugging during debugging. Consumables usage such as ink.
(3) Production is more flexible
The platform-type exposure structure has incomparable advantages over other exposure structures. For the missing pages, it can be vacant, and the existing pages are exposed first, and the vacant files can be supplemented after they arrive. There is no need to wait passively like other CTPs. The page is ready to be exposed. Simultaneous exposure of 2 smaller plates
(4) Flexible selection of printing plates
For different jobs, both negative and positive versions can be used, and the choice of initiative is completely controlled by the customer. General text-based prints,using negative pattern regular PS version.If the image area on the printing plate is large, or some special inks are highly corrosive, the positive PS version can be used, which saves time and is more efficient.
(4) Fast, stable and smooth integration with the traditional PS printing process
The PS version's on-machine printing and image reproduction capabilities have been tested in the market for a long time and have been recognized. The technical process has been perfected and has been widely used in the printing industry. The introduction of CTcP can continue to use the original plate processor and developer solution; and can reduce the downtime for plate change during printing. The original printing parameters such as ink balance and printing pressure do not need to be re-tested. It not only ensures the stability of printing, but also ensures economy and high efficiency.
