The operator of the printing press is familiar with the "borrowing drum". During the printing process, when he encounters some special jobs or in order to reduce the loss of the paper, the printing press personnel should rotate the plate cylinder (the performance of the oil-cooled drum motor of the TDY type). To the right place, the contents on the plate can be printed on the paper to the corresponding position according to customer requirements. Printing staff all know the drawbacks of borrowing the drum. First, it takes time and effort. After printing, the drum is adjusted twice before printing and the working time is about 20 minutes. Second, when the printing drum is borrowed, the rotation position of the four-color drum is impossible. Accurate and consistent, to bring difficulties to the rules for printing, under normal circumstances to find rules 2 to 3 times to find good, after the drum, find the rules at least 4 to 5 times. Due to the increase in the number of times, the “discharge†of the paper used to find the rules will increase, and the time taken will increase. As a result, the efficiency will decrease, the material consumption will increase, and the production cost will increase. Third, the phenomenon of borrowing drums will appear frequently in daily production. Due to too many drum borrowings, employees will inevitably avoid mistakes or screw-screws in the actual operation process. This will bring safety risks to production equipment and reduce the risk. The service life of the machine, for this reason, we further studied the principle of borrowing the drum, knowing why to borrow the roller, if not borrowing the roller, other methods will not work, we will start thinking again and again, think of the printing process, in the traditional drying During the printing process, the film is attached to a certain position of the PS plate. Usually, the plate-printing staff prints according to the size of a fixed printing mouthpiece provided by different types of printing machines. Now, we change the size of the printing platen bite. Live, the plate cylinder becomes stationary. Through a period of practice, this method has been effective, changed the traditional work practices, and significantly improved work efficiency.
In October 2001, Classical Color Printing Co. bought a new Japanese Ryobi lithographic printing press. After using it for a period of time, the quality inspection personnel found that the printed film had spots of different sizes on some of the printed matter. They began to think that it was caused by dirt during the film coating process. After investigation and analysis, it was inferred that Spraying is too large during the printing process. After reducing the amount of dusting, the situation has improved, and the number and frequency of prints with spots have been reduced. However, this phenomenon has not been completely eliminated, and the size and location of the spots have not been regular, and the problem has not been completely solved. The company had no choice but to increase the number of papers to increase the number of inspections and strengthen the inspections by quality inspectors. The number of spots encountered was large, and when the number of finished products was insufficient, they could be printed. The existence of this problem has, over time, made everyone realize that it has brought great influence to the company in terms of material consumption, product quality, and work efficiency. The company's leadership is determined to focus on gathering all the key technical personnel, brainstorming, investigating the causes, finding the crux, analyzing and researching, and gradually checking, and finally inferring that it is due to accumulation of dust on the delivery parts. After the conclusion was reached, the company asked the printing press personnel to clean the powder on the delivery part regularly. Since then, the phenomenon of "spotting" has never occurred again. In the past, when the master knife maker cut the finished product, no matter how large the finished product was, the width of the white paper was cut along the finished product line. The cut waste paper was sold in full paper, due to waste paper and The waste paper price difference is too large, a difference of 0.6-0.7 yuan per kilogram. This uses a white paper edge and a two-knife cutting edge. Although the machine blade cuts the finished product more than normal, the company considers two. Knife cut may be more cost-effective than everything, since then, when the edge of waste white paper reaches a certain width, the cutter must be two-handed. After accounting for the next few months, it was found that the sales of waste paper increased by several thousand dollars over the previous months, verifying the correctness of the company's decision to replace the process.
In 2001, the Classical company introduced a Japanese Ryobi 684. In the initial stage of use, according to the manufacturer's requirements, a 680×550 size PS plate was used. In actual work, it was found that the paper size most commonly used by Ryobi printers was 59×44; under normal circumstances, it did not exceed this size, and the company decided to use a 650×550 size PS plate instead of a 680×550 size PS plate. Reducing the use of PS plates, although using a 650 × 550 size PS plate, will cause the blankets to no longer print more than the size of the job, but after repeated and careful measurement, only changes in size, saving PS plate materials costs nearly 30,000 a year yuan.
Through the above few small reforms, the importance of technological transformation and gizmos in the development of the enterprise has been recognized. The Classical Corporation is a small printing company with more than 30 people. The annual net profit is 200,000 to 300,000 yuan. The use of measures will reduce the production cost of the company by more than 100,000 yuan each year.
