Modern technology CtP (Computer-to-Plate) provides the ability to directly transfer images from a computer to a printed sheet, without any additional operations. This option has breathed new life into offset printing, allowing you to quickly and reliably get better quality images. The production of offset CTP forms is carried out using a laser beam and additional chemical processing. The release of the plates takes much less time, and the elimination of the human factor from the process minimizes possible inaccuracies.
The First Exemplary Printing House has all the power to create CTP plates. Our equipment allows you to significantly speed up the printing process and provide the finished result to the client as soon as possible without deterioration in quality. We offer the manufacture of printing plates of various formats and ranges at an affordable price.
What is CtP technology?
The CtP direct printing method is considered quite new, but in fact, the first laser devices appeared in the 60s. last century. Of course, they were only distant prototypes of modern devices, and the direct analogue of Computer-to-Plate was created in the 80s. In it, the radiation source was a YAG laser with a wavelength of 1.064 μm. The first apparatus produced CtP plates with dimensions of 530 * 650 mm.
Over time, the device has become very popular. In conditions of high production load with a flow of orders, the advantages of this technology became obvious:
- Reducing the time of makeready work and shaping processes by eliminating one rather large-scale stage.
- Improve the clarity, accuracy and quality of image reproduction on forms.
- Minimization of paper waste and ink costs, and therefore a reduction in the cost of finished products.
- Reducing the risk of errors due to the maximum automation of processes.
Types of plates
Three types of plates are widely used in modern printing houses, each with its own pros / cons. Thus, the production of CtP offset forms is directly related to their type. Therefore, let’s take a closer look at each of them:
- Silver. During the process, hydrophobic areas with a silver base are formed. The print elements are formed on a hydrophilic substrate. They feature high resolution for maximum print quality. At the same time, in terms of circulation, they are inferior to other varieties. Also, silver-containing forms cannot be used with varnishes, metallized, UV paints.
- Thermal. These CTP plates also have the highest resolution as well as good toughness, allowing them to work with all types of ink. It is important to correctly configure the equipment for a specific brand of plates in order to obtain the highest quality result. Among the disadvantages, one can single out low speed, requiring the use of a large number of lasers at once. This contributes to the rise in the cost of both the equipment itself and the final product.
- Photopolymer. In this case, plates are used that are sensitive to radiation with different wavelengths. In terms of the speed of work, photopolymer forms are inferior to silver-containing ones, but several times higher than thermal ones. Initially, they were used exclusively for the production of newspapers, as they were not of high quality. But modern elements have a high resolution, suitable for magazines and other types of printing.
Why it is worth ordering CtP offset forms from First Exemplary Printing House

CTP (from the English Computer to Plate) is a technology for the production of printed forms. Printed elements on plates are formed by illuminating the plates with a laser beam and subsequent chemical processing.
