Small and medium-sized printing enterprises use CTP knowledge correctly

At present, the vast majority of small and medium-sized printing enterprises generally have the confusion that it is easy to introduce CTP and difficult to use CTP well. The reason is that the printing buyers are the result of the quality of the printed matter, rather than the CTP plate. The application of CTP by printing companies is essentially to simplify the plate-making process under the premise of ensuring the quality of the printing plate, that is, to use CTP as a bridge to integrate the processes of pre-press, printing and post-press processing. However, when printing companies actually use CTP, they will find that the transfer of simulated analog outlets in the traditional CTF process becomes the data transmission in the invisible CTP process. When the operator cannot analyze and control the data relationship between pre-press and printing At times, it is difficult to really take advantage of CTP.

It is easier for small and medium-sized printing companies to use CTP better than CTF, and there are four issues to be solved. The first is to select the appropriate CTP and digital workflow from the perspective of solving its own defects and deficiencies according to its own product characteristics and precision requirements, cost requirements, management level and quality control methods.

The second is to use digital methods to improve the adaptation of each process that directly affects or determines the printing results. For example, establish a CTP process to unify the data format, color management methods, tone transfer characteristics and optimal printing conditions in the production process, standardize the page group plate processing method and the layout principle for different folding and binding methods, and solve the digital problem. Proofing, matching problem between CTP plate and printing machine.

Thirdly, to ensure that products with different quality standards can achieve the most reasonable process control and parameter setting under different printing conditions, without relying on the experience of the operator.

The last is to strengthen the transformation of the core technical personnel and managers of the enterprise from aA type inspection and control to digital analysis and control of ideas and operation methods, especially to help technical and management personnel understand and grasp the overall adaptation between the various processes under the CTP process method.

In short, the key to realizing the normal operation of all production processes under the CTP process is to use scientific and reasonable quality control methods and detection methods based on the characteristics of the printing press to form a solution that uses data as the operating standard and quality specification. Through the cooperation of CTP and printing machine, the goal of using CTP well, ensuring stable printing color and satisfying the quality requirements of printing buyers can be achieved.
