Talking about the maintenance of CTP

The pre-press revolution brought about by CTP technology has brought a lot of benefits to early investors. As CTP becomes more and more mature today, with the increase of material cost, labor cost and price, it has brought a lot of printing enterprises. pressure. A new round of CTP buyers no longer only focuses on technology and processes. What they are thinking about is how to effectively reduce the cost of use and increase efficiency. Of course, as a sensible purchaser, there must be a sufficient preparation for the operation of the pre-CTP. The cost of laser head replacement, equipment maintenance and downtime is also necessary. This article will also be from another perspective: CTP The equipment maintenance cost of equipment after-sales maintenance costs, how to effectively reduce the cost of CTP maintenance and the importance of CTP maintenance, for you to interpret CTP maintenance solutions.

First, the cost of CTP maintenance costs

At the beginning of CTP, more CTP investors only used the CTP laser head as an important part in the process of using the maintenance cost. Therefore, after purchasing, they often worried about the damage of the laser head and increased the maintenance cost. The real maintenance costs include the following:

1. The cost of parts refers to the cost of purchasing parts when the CTP equipment fails. It basically includes the laser part, circuit part and related parts of the mechanical part of the CTP equipment.

2. Consumables costs refer to some lossy parts that CTP equipment needs to replace on time during use. For example: air filter, dust filter, detection control and so on.

3. Maintenance service fee refers to the expenses incurred during the maintenance process, including the related expenses incurred by the factory maintenance personnel or external personnel.

4. The cost of shutdown is the cost of the CTP machine shutdown, which is usually not included in the maintenance and maintenance, but can be used as reference data for cost calculation.

Under normal circumstances, there will be a corresponding warranty contract between the CTP supplier and the purchaser. Therefore, during the first year of the warranty period, the customer usually has peace of mind. Once the warranty period expires, most customers will worry about the equipment failure and cause lost work. The cost of parts and materials that are actually spent in the post-warranty period are as follows:

The following data will vary slightly from vendor to vendor. The data is calculated by standard and the price is for reference only:

This is calculated, if a business-oriented printing company, and is divided into 2 to 3 classes of 24 small jobs, a single machine in 22 sheets per hour, published in about one year in about 120,000, in a year in the CTP machine In the case of normal operation, the required consumables cost roughly: $1,7220.00.

Some calculations will cause some customers to scream. The cost of one piece of our CTP is far more than that. If all the maintenance of the user relies on the supplier to operate, it may cost a higher fee. But now most suppliers are more willing to choose the relevant maintenance contract to provide services, so that time and technology are more secure, even if this is to talk about the following common problems and maintenance related to CTP. [next]

Second, the common problems of CTP machines

In the process of using CTP machines, due to its compact structure and good design, the problem is generally less, but long-term actions inevitably have some problems. The following common problems are listed as follows:

1. The failure of the entry system, most CTP entry systems are operated by pneumatic devices. The pneumatic part includes the protection door of the machine, the plate rubber roller, the plate head clamp, the plate tail clamp and other devices. Some of the adjustments can be made by most customers themselves, and even some parts customers can replace them themselves.

2, the failure during the exposure process, relative to the mechanical action, the failure occurred during exposure may be a bit tricky, but as long as the analysis is not difficult to find the problem, we can analyze according to the idea: the failure of the plate itself, Faults in the development process, documentation problems, problems in the exposure process, and human problems, so that problems can be easily found to further solve.

3, the circuit and the sensing part of the problem, the circuit problem usually includes the software to guide and store the data, and the sensing part is the operation detection of all actions and security devices, the machine's error message can mostly point out the core of the problem For the solution and solution, the customer can solve the problem by himself or by contacting the relevant technical personnel.

4, the laser part of the problem, the laser problem is mostly manifested in the output of the plate, generally can be solved by adjustment, and if the temperature and humidity cause problems, customers can also solve their own, if it is really few If the laser internal circuit fails, it needs to be replaced.

5. The failure of the next version is the same as that of the previous version. The lower part is divided into automatic and manual. Most of them are mechanical movements and some positions. As long as there are more maintenance, there will be no major failures.

The general part of the common problems listed above is also to remind customers that a stable CTP system needs to be carefully maintained. Good maintenance includes:

Third, CTP maintenance content

Through daily and planned cleaning, lubrication and proper adjustment of equipment maintenance, the maintenance cost of the equipment can be minimized. The maintenance of CTP equipment is mainly reflected in the following aspects:

1. Observe the safe operation and strictly eliminate the unsafe factors in accordance with the physical and chemical safety of the equipment.

2, proper lubrication, good lubrication can effectively improve the operating part, especially the CTP screw and slide, must be regularly added with qualified oil.

3. Arrange the relevant connection lines and air intake, drainage and other devices. If all the connecting parts can work normally, it will surely ensure the normal operation of the whole system.

4, cleaning the inside and outside of the machine, cleaning is the first of all maintenance content, inside the CTP machine due to the dust of the laser burning candle, the attachment of the movement of each rubber roller will inevitably increase the load of the machine. Therefore, cleaning is especially important during the use of CTP.

5, properly adjust the ambient temperature and humidity, temperature and humidity are critical for CTP machines, too high temperature can cause accelerated aging of the thermal laser head, too high humidity is quite unfavorable for the cleaning of the plate and the machine, so CTP The machine is best used within the specified temperature and humidity range. In case of abnormal temperature and humidity, it is recommended that you adjust the environment quickly. The normal CTP room temperature is 20±2°C and the humidity is 50%±10. The comfortable environment not only guarantees the machine. The normal operation can also stabilize the quality of the product.

6. Ensure the normal input voltage and air pressure. The clean and stable voltage and air pressure are the primary conditions for the healthy operation of the machine. The input of the standard voltage to each circuit and switching power supply can ensure the normal operation of the circuit board, and the air pressure can stabilize the laser head. Effective dust removal keeps the moving parts in good working order.

Of course, in the process of using CTP, it is more important for each company to manage the relevant maintenance content according to its own needs.

Fourth, the importance of CTP equipment maintenance

The daily maintenance of equipment is the basic work of equipment maintenance. Its importance is directly reflected in its production value. In the long-term maintenance of CTP, most people think that the life of thermal laser head is 3000-5000 hours, but it is good. In the environment, the use of thermal laser heads for more than 10,000 hours has been unclear. The environment in which these tens of thousands of hours of laser heads are located is definitely quite good, plus the good quality of CTP operators. Not only solve the problem from time, but more importantly, it reduces the maintenance and repair costs, thus improving the efficiency.

Cooperation with suppliers can not only improve the skills of CTP operators, but also understand the performance of equipment in learning, so as to control CTP machines. At present, most of the supply in the CTP market can provide good services to customers. And a variety of solutions, such as: Kodak's remote diagnosis, 800 free phone and network technology technology platform, are providing customers with meticulous service care. Therefore, when there is a problem with the machine, we need to consult more professional personnel in time to deal with it, instead of wasting maintenance time.

On the other hand, many merchants only purchase one CTP device, and if the maintenance process is negligent, the process in the entire flow printing operation will be shut down, and the loss will be even greater. Here, we must remind the CTP administrator that the careful maintenance of the CTP equipment relies on the operator to complete and execute only the correct use of the equipment by the operator, in order to maintain the good performance of the equipment, to fully utilize the equipment efficiency and extend the service life, while reducing or Avoid sudden failures, and don't rely on solutions that go wrong and repair.

When you are sure to purchase CTP equipment, pay attention to the equipment to bring you benefits, but also pay attention to your maintenance plan for the equipment, through daily maintenance and accumulated and summarized lessons, cultivate awareness of protection, rely on initiative Maintenance methods to minimize failures and reduce losses, so that CTP equipment can really achieve long-term and high-yield.
