Inkjet type CTP plate and system as a member of the CTP family, Guangzhou business card printing, as early as the 20th century, there are companies abroad to carry out related research and development work, but in view of the soft and hardware limitations of the time, Changchun printing, there is no Fully developed.
Compared with the current laser photo arrangement, its advantages are reflected in the following aspects.
(1) Material aspects
It saves the cost of materials and equipment for film, exposure, rinsing, and revision.
(2) Benefits
Since the above processes and materials are omitted, the cost of plate making is greatly reduced, saving time and space. The use of inkjet CTP technology will reduce prepress platemaking costs by 30% to 50%.
(3) Time aspect
It reduces the time for punching and shortens the printing cycle of coated paper, especially for the newspaper industry.
(4) Quality aspects
Since the film is omitted, the graphic information is stepped from the computer to the printing plate, and the precision of the layout and the quality of the image transfer are further improved.
(5) Number of employees
A medium-sized printing offset printing machine saves many workers in imposition (including folding calculations), proofreading, and preservation of searched film (reprinted).
(6) Price aspect
The system input cost is only 1/10 of the traditional laser imagesetter, and the price of the plate is almost the same as the current PS version.
(7) Environmental aspects
It fundamentally eliminates the serious pollution problem caused by the discharge of silver-containing wastewater during the photo-discharging process, and is a green environmentally friendly product.
(8) Equipment aspects
Equipment such as darkrooms and laser imagesetters have been eliminated from the printing plant, and space and facilities for storing film (reprint) have been saved.
(9) Technical aspects
The technology is easy to learn and easy to master.
(10) Comparison of plate making process
Inkjet CTP platemaking process: group version → pattern version → plate making.
Traditional plate making process: group version → phototype machine → film → development → fixing → imposition → revision → printing → plate making.
In summary, the inkjet-type CTP system and the plate of the Beijing Printing College homepage will realize the pre-press digitalization, high-speed and automation of the printing industry with a very low investment. It is an advanced technological revolution in line with China's national conditions.
