With the continuous development and growth of China's printing industry, traditional pre-press processes and pre-press equipment have been gradually replaced by new processes and equipment. Today's prepress equipment has made great progress both in terms of mechanization and automation. If the maintenance and management are not in place, the equipment will not operate, and it will inevitably affect the printing process cannot be operated normally, resulting in economic losses . To extend the service life of various equipment before printing, it is essential to do the following maintenance work.
1. Classified management according to the function of pre-press equipment
To maintain and manage pre-press equipment, the equipment should be classified first, and then according to the type of equipment, its working characteristics should be targeted to develop maintenance plans and related management measures.
Today's prepress equipment generally has the following categories: ①Output equipment, mainly including laser phototypesetting output machine and film developing machine. ② Imposition equipment, imposition machine. ③Proofing equipment is mainly divided into traditional proofing machine and digital proofing machine. ④ Exposure equipment, mainly including exposure machine and processor. ⑤ Direct plate-making equipment, mainly CTP equipment. Whether these devices are domestic or imported, their working principles and maintenance requirements are basically the same, as long as they are in accordance with the requirements of the equipment manual, and then according to the characteristics of the equipment, the maintenance plan should be formulated accordingly.
2. External measures to ensure smooth maintenance of prepress equipment
â‘ Environmental control. For the maintenance plan to be truly implemented, the control of objective conditions is crucial. This mainly refers to the environment where the prepress equipment is located. Since most of the prepress equipment cannot be separated from liquid during normal operation, the output device needs to use developer and fixer, and the printing equipment also needs to be developed. Liquid and water are used for plate making, not to mention the direct plate making equipment. Since most of the prepress equipment is composed of advanced electrical components and integrated circuits, it is particularly sensitive to temperature and humidity. Too high and too low temperatures and humidity will affect the service life of the equipment.
Another environmental factor that affects the normal operation of prepress equipment is dust. Dust is the enemy of all pre-press equipment. A small dust can stop the entire output device, and can make the rubber roller of the punching machine scratched and scrapped. Therefore, it is important to clean the space where the equipment is placed.
To enable the environment to be effectively controlled, first of all, the equipment should be separated according to function, and the mutual influence between the equipment should be minimized. The second is to install air conditioning equipment, air conditioning equipment can not only ensure that the prepress workshop to achieve constant temperature and humidity, reduce the spread of dust. The most important point is that the scanning head and laser head inside the current laser imagesetter and CTP equipment need to work under constant temperature conditions. Therefore, the air-conditioning equipment should be installed as well as always open, so as to ensure that the pre-press equipment can work normally in a good environment.
â‘¡ Establish a pre-job training system for equipment users. Pre-job training is a prerequisite to ensure the normal operation of each pre-press equipment. Some companies think that training is a headache. In fact, when each company introduces a pre-press equipment, the equipment The manufacturer will provide free training for the personnel who will use this equipment in the future. In this process, the operators who have mastered this equipment will compile the correct method of using this equipment and the main content of maintenance into simple and concise instructions. It is bound into a booklet. When the newly recruited staff prepares to operate this equipment, this staff must read this operation manual carefully, confirm the signature after understanding and proficiency, and then the staff who have participated in the training of new equipment will guide their specific operations Skilled and incompetent will not allow it to operate on the machine. In this way, when it is later discovered that the equipment accident is due to the operator not following the requirements, the party is punished. In this way, skilled employees bring new employees, and the continuation of the company will reduce a lot of flashy training work and focus more on production.
3. The establishment and implementation of the system is the key to the implementation of equipment maintenance
â‘ The implementation of measures is the key to management. When each printing company starts to introduce equipment, the maintenance of the equipment will surely formulate many related specific measures and implementation plans. From the establishment of equipment files, to the appointment of designated personnel to manage, determine the responsible person, etc., it is very perfect and in place. However, abnormal damage caused by improper equipment maintenance often occurs. The main reason is that the characteristics of the pre-press equipment are different from those of other equipment. The pre-press equipment is often used by multiple people on one device, such as a copy machine. , Punching machine, etc., as long as it is available to everyone in the printing room, and the printing room often works 24 hours, if the failure is not a big problem, sometimes in order to catch up with the task, it is usually repaired by the repairman. No longer be held accountable. In this way, the maintenance of the equipment cannot be achieved at all.
To solve this problem, in addition to writing the name of the person in charge next to the equipment to strengthen the sense of responsibility and supervision, you can also use the equipment intact rate to be linked to rewards and penalties. In case of problems, the maintenance personnel shall first issue a maintenance report to the supervisor. If the maintenance is improper, the responsible person will be punished. If the responsible person changes, the responsible person shall be changed in time.
â‘¡ Carry out maintenance in strict accordance with the maintenance procedures. Post the relevant operating procedures of each equipment, daily cleaning and maintenance and lubrication system next to the equipment, and the responsible person is responsible for daily maintenance according to the regulations. If the developing machine needs to clean the developing, fixing and water tank regularly, and the printing machine needs to refuel the air pump in time, it must be carried out according to the instruction manual of the equipment. In fact, a lot of maintenance work can be done without downtime or downtime for a long time, mainly because the relevant personnel have done as required. However, some maintenance work must be shut down for a long time to perform maintenance. For example, when the PS version of the printing machine has to be shut down for maintenance for three months, it should be maintained on time under the premise of arranging production. And forget to maintain, or just care about production and not willing to maintain.
In fact, most of the equipment before printing needs to be done in terms of maintenance, as long as it is in place and quality is ensured when doing maintenance. Only in this way can the performance of the equipment be relatively stable, and the production of the enterprise can proceed smoothly.
