The author is a captain of Adast's four-color four-color printing machine. During the work of the lead machine, the author found some problems that affected the company's production efficiency and the saving of auxiliary materials. I would like to make the following suggestions for reference: The first is the issue of the edition room. The printing room is a very critical process before printing. Their small mistakes may cause serious quality accidents. At present, the author's printing room staff is not strong in their work responsibilities, and the problems that arise are all very low-level errors. If you do not carefully compare the proofs when you are printing, you will often get the following: slamming, reversing, misspelling , Too many dirty spots, etc. At that time, the author averaged as many as 3 supplements in a day's work, among which there were often a set of three sunburned; this waste can be prevented. The second is the problem of developer. Because the developer will react with the oxygen in the air, the developer should be stored in a sealed container, thereby reducing the efficiency or failure of the developer, causing problems such as dirty and dirty during development, and affecting the printing quality. In addition, the ratio of the developer should be found in a measuring cup. The ratio of the developer and the water will be out of balance by feeling. The development time should also be recorded with a table. The development time is generally 34 to 45 seconds; When the ratio is different, you can increase or decrease the number of seconds. It is not good to see this method. When the concentration of the developer is too large, when you see it, it will be displayed after it is taken out. If the concentration is not enough or the developer is oxidized, the layout is There will be a layer of bottom ash during printing. After development, you should wipe the plate protector to protect the plate surface, which can reduce dirty spots and extend the life of the PS version. The PS plate is easy to oxidize after the development is completed, and the hydrophilic layer and the photosensitive layer of the plate surface are damaged by oxidation, and the plate surface will be dirty after the hydrophilic layer is destroyed; after the photosensitive layer is damaged, the graphic part will not be inked, thereby reducing the PS plate life. A PS version can print 40,000 ~ 50,000 prints after erasing glue, and 30,000 ~ 40,000 prints can be printed without erasing glue. For example, when a live 40,000 print is printed to 35000, the PS version is damaged. At this time, replacing the PS version takes time and material. Wipe The glue may be printed. The third is the maintenance of the machine. Maintenance needs to be sorted. When idle, clean the paper collection chain and the powder spray behind. It is worth noting the speed problem: the machine is running too fast, the long version can work, but the short version is not necessarily efficient, and the short version is not the machine that can be fast. The effect of printing slowly will be more beautiful, and the dots will be clearer. It is wrong to just pursue fast speed. The machine runs at such a high speed every day. The transmission inside is gears and chains. If the speed is running at 8500 ~ 9000, if you accidentally lock the car or Feida stops, it will be gears and Feida. It will cause great damage, and other components will also be damaged. For a long time, small problems will become serious problems. If a machine can be used for five years, the slow speed can be used carefully to repay the loan for two years. But as long as the fast drive is efficient, the loan is also earned for three years. But in reality, this is not the case. The machine wears out because the machine has been driven too fast, and replacement parts will cost money; but if the machine is driven slowly and diligently maintained, the machine will not have this problem. Why are the machines repaying loans in three years? Because the output is the same, the machine is turned on slowly, not by the speed to increase the output, but from the efficiency of the work of the relevant personnel and the pre-press preparation to save. Give a simple example, such as printing 5000 jobs, opening 9000 speed, printing 150 sheets in 1 minute, 5000 sheets can take 33 minutes, 10 minutes before printing, 15 minutes for printing, 20 minutes for printing, printing time Stop in the middle for 5 minutes and share 83 minutes. If the machine is opened at 7500, 125 sheets are printed in 1 minute, and it takes 40 minutes to print 5000 sheets. It takes 8 minutes for the first edition, 10 minutes for the edition, and 10 minutes for the revision. In order to run the color evenly a little better and run the ink for 5 minutes, 73 minutes in total. Time is won by pre-press preparations. The fourth question. It is necessary to improve the sense of responsibility and enthusiasm of employees. The waste of auxiliary materials in daily work is very serious, and it is paper; the use of rubber blankets should also pay attention to. Cleaning the rubber frequently will make the dots clearer and reduce the frequent occurrence of ink accumulation. Fill in the daily report in a timely manner. A set of time should be printed when the machine is working. This can improve the time concept of the staff. The office also clearly knows the time of this set of versions, find out why this set of plates is a waste of time, and coordinate Improve all aspects and improve the deficiencies. As the leader of a machine, we must take responsibility for ourselves, so that we can stimulate the work enthusiasm of other personnel. The power of role models is endless. The above is just my humble opinion, I hope the company can save costs, improve efficiency and flourish in a real sense.
