Printing companies to buy CTP have a trick to clean bright eye selection equipment

Ningbo Changjiang Yinye Development Co., Ltd. in 2004 and 2012 respectively introduced a Creo VLFCTP plate-making system and a 1100CTP plate-making system from China and India. Over the years, the company has fully felt the convenience and benefits brought by CTP. In fact, when purchasing CTP, not only depends on the stability of the hardware equipment, but also on the specific process software, training services, after-sales service, and equipment maintenance costs.

When purchasing CTP in 2004, the company mainly considered the following aspects, and conducted an in-depth investigation. 1 Must be a brand that is generally recognized in the domestic market, has a good reputation, and has excellent quality and after-sales service. 2 In order to make the selection of thermal plate wider, the adjustable range of the output energy of the CTP laser head should be larger. At the same time, in order to ensure that the plate has a high resistance to printing, the CTP should be strongly exposed and weakly developed. 3 In order to ensure the consistency and stability of the dot restoration, it is required that the CTP does not cause the imaging focal length to change due to the expansion and contraction of the drum caused by sudden temperature changes. 4CTP's maximum plate format and output accuracy, publishing speed, etc., can be matched with the company's existing equipment printing. This not only saves time, reduces platemaking costs, reduces the waste of overprinting paper and plate, but also improves the printing quality. . In addition, when purchasing CTP, we also considered the technical level and work experience of the company's prepress operators. Because only the prepress operators themselves have a wealth of prepress work experience and a certain color management knowledge, plus some system training, combined with the company's strict product quality control system, CTP can play a good role in the company's More benefits.

In 2012, with the expansion of the company's business volume, the original CTP was far from meeting the increasing production demand, and the acquisition of new CTPs was an urgent task. At this time, CTP technology has matured, and some domestic CTPs can also compete with imported CTPs. Therefore, when the company purchased CTP in 2012, it will cover the excellent national CTP brand. In this purchase, we mainly consider the following aspects. While 1CTP has high output accuracy, it also needs to ensure the publication speed so as to ensure both the printing quality and the production efficiency. 2CTP should be able to identify PDF files so that files between two CTP systems can be shared. The 3 format should be complementary to the previously purchased CTP format to facilitate the company's future expansion of its business scope. 4 simple and easy to maintain. 5 perfect after-sales service

In short, when purchasing CTPs, printing companies should conduct in-depth investigation and research and make reasonable choices according to their own needs.

Many aspects cut in, brighten the eye to choose the equipment to choose a stable performance, excellent output quality, training and service in place, low maintenance cost of CTP is a dream for many printing companies. When purchasing a CTP, a printing company must first analyze its own situation to understand its own purchasing power, business type, print quality requirements, and delivery deadlines. Based on this, the following points should be used to make further judgments. , I believe we can find the right equipment.

Output quality

The output quality of CTP directly affects the quality of printed products. Printing companies should make reasonable choices in accordance with the needs of their own printing business. For example, high-end albums or three-dimensional prints require very high print quality, and the number of print screens for prints must reach 400 lpi. For printing companies that print these services, when they choose CTP, Need to pay more attention to high-resolution equipment; printing enterprises that only print some simple printed matter, the CTP with particularly high-accuracy purchasing is wasteful, and the dots displayed by the printing plates may not be able to be printed in the corresponding printing. Things are reflected.

2. Output speed

Due to the short version of printing jobs, printing companies are increasingly concerned about the output speed of CTP. In fact, speed is not a problem for CTP manufacturers. When purchasing CTPs, printing companies can purchase CTPs with corresponding output speeds according to their own business volume requirements. It is worth mentioning that the output speed of CTP has been upgraded in recent years. For example, when a business is small, a printing company purchases a CTP that is not very fast. Later, due to the development of the company, higher requirements are imposed on the output speed of the CTP. At this time, the printing company only needs to purchase the CTP output. Speed ​​upgrade service, you can.

In fact, the output speed of CTP not only includes the speed of CTP plate making, but also includes the processing speed of CTP for prepress files. There are two main ways to improve this speed: First, the process is based on computer hardware. To improve efficiency, it is necessary to upgrade the corresponding hardware; second, the CTP system to image and text information in the prepress file The processing method will also affect its speed, so the timely upgrade of the system and related software will also help the CTP output speed.

3. Compatibility

When printing companies purchase or purchase CTPs, they often consider whether the new CTP process can be compatible with the printing equipment or the original CTP process, and the core is the compatibility of the documents.

The same file interface can ensure smooth communication of information. Even if several printing companies purchase a few processes that are not fully compatible with each other, as long as they can accept third-party raster processing files, that is, 1-bit TIFF bitmap files, the system is still relatively open, and each process can be Information is communicated on the basis of such documents. At present, most CTP processes have this kind of function, but the opening of the function also needs to pay a certain fee.

4. Ink data tracking

In order to cope with the current trend of short-page printing jobs, CTP effectively help printing companies complete the first printing (the first finished product printed out) as soon as possible. Many CTP manufacturers have opened the ink data tracking function. This function is to give an ink preset file at the same time in the CTP plate making, so that the printing press adjusts the ink amount of each color and each ink zone to the corresponding level according to the original color requirement before printing, thereby shortening the printing preparation time. . When CIP3 was not used before, the press was ready to use more than 200 pieces of overprinting paper before it could print out the first finished product; now with CIP3, some experienced chefs may only need 30-40 pieces. Printing paper, you can complete the first print. This will save labor costs, time costs, and consumables costs for short-term printing.

Printing companies in the examination of this function of the CTP, pay attention to two aspects: First, the accuracy of the CIP3 ink data, high accuracy of the ink preset file, can complete the first print faster; Second The printing company must also make it clear whether the existing printers have also opened this function and whether its interface matches the CTP interface to be purchased.

In addition to the above points, in the process of purchasing CTPs, printing companies need to consider all aspects of the company's actual situation, operating costs, recycling benefits, staffing, and future development directions.
