Eight-color rotary offset printing is one of the major hotspots for the introduction of equipment in the printing industry in recent years. This hot wave has its origins in the ever-increasing competition in China's printing market and the increasingly mature and detailed printed consumer market. Offset offset printing, especially commercial offset offset printing, is expensive, while commercial printing products with higher added value use low-volume roll coated paper.
Due to the special nature of webs, it is difficult to quantify the management of webs using the flat sheet management method. However, if the management of webs cannot keep up, even if the business volume is sufficient, the profitability of web offset printing equipment will be difficult to increase. Therefore, it is inevitable to explore ways to save web offset printing paper.
There are three characteristics of web offset printing: high printing speed, many additional functions, and high operating costs. Its high print speed performance in the general publication of the maximum speed of rotary offset 20,000 off double-sided four-color / two-color / monochrome posts, commercial, semi-commercial 8-color offset offset printing speeds of up to 35,000 to more than 50,000 on the color order . Therefore, if the operator's technology is not very mature, or the response to the equipment failure, the processing is not timely, or can not be found in the debugging stage may lead to a large number of printed materials scrapped, the paper waste caused by commercial web offset will be very alarming.
Commercial and semi-commercial offset offset presses have many additional functions, including drying, cooling, and polishing, and are suitable for the requirements of rapid commercial printing, large batches, multiple batches, multi-layers, personalization, high-grade, and colorization. This is often very necessary, but correspondingly, the paper path has been lengthened to further increase paper consumption for paper-making and debugging.
High operating costs. Commercial web offsets have high performance requirements for parts, raw and auxiliary materials, and even lubricating oils. In addition, if additional functions are enabled, the running costs are very high. Therefore, the requirements for management in all aspects are also high. Otherwise, even if processed products are high-value-added products, these attractive profits will be swallowed up by the consumption of commercial rotation “aristocratic†operations.
After understanding the characteristics of rotary offset production mentioned above, it is necessary to exercise scientific control over management in order to achieve the purpose of saving paper. In management, we must put two things together. One is the warehousing and the second is the paper clearance. Regardless of storage, or printing on the machine, it is necessary to count the volumes of the machine paper according to the type and batch of printed products, so as to ensure that the records are not missed, are not re-recorded, the records are accurate, and are not fraudulent. The paper store managers and workshops Machines also need regular reconciliation and mutual supervision.
The weight of each roll of the roll paper is marked on the manufacturer's roll. However, the weight of each roll is not exactly the same, and it must be counted roll by roll before entering the store or machine to ensure the accuracy of the number of paper and paper used. Even if the web is piled directly on the shop floor, the paper store managers must register the paper when it enters the market and check with the paper management staff on the shop floor to sign the confirmation on the other party’s account. After receiving the registration in accordance with the regulations, the recipient shall indicate on the outer package of the paper roll that there is a unique identification volume number compiled by the paper store management personnel according to the labeling standard, so that the next procedure can fill in the number when filling in other items.
The machine table is continuously produced. After each printed product is finished, it seldom happens to use up the paper on the machine. After the paper is unloaded and then weighed, the paper is neither troublesome nor feasible. The monitoring and continuous improvement of paper usage in the production process is done using a sheet, the paper input-output balance sheet. According to the situation, the situation on the paper input-output balance sheet is analyzed monthly (quarter/year) in order to find out the propensity problems and find out the reasons and take corresponding corrective and preventive measures.
For general and semi-commercial 8-color rotary offset printing paper, which is generally longer, a special paper roll holder can be made by itself, and the core tail paper can be used to wear paper. The specific approach: the paper holder is placed between the secondary tension and the second printing unit, through the various printing units and various parts of the post-press function, until the folded part of the triangle plate piercing, and then in the secondary tension roller and wear out The upper paper part of the paper roll is connected. This method can be used for paper-making operations such as paper-feeding, paper-feeding, and paper-feeding. The use of actual measurement on the Harris 30 Heisberg V30 semi-commercial 8-color offset offset printing can save 30 meters at a time.
