Talk about how to save paper with eight color rubber wheel printing

The eight-color rubber wheel is one of the major hotspots for the introduction of equipment in the printing industry in recent years. This boom has originated from the ever-increasing competition in China's printing market and the increasingly mature and detailed printed consumer market. Rubber tires, especially commercial rubber tires, are expensive, while commercial printing products with higher added value use low-volume reel 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 be kept up, even if the business volume is sufficient, the profitability of rotating equipment will be difficult to increase. Therefore, it is inevitable to explore the potential for saving rubber tires.

Master rubber wheel characteristics

Rubber wheel production features three: high printing speed, additional features, high operating costs.

Its high print speed performance in the general book rubber tire speed up to 20,000 off double-sided four-color / double-color / monochrome posts, commercial, semi-commercial 8-color rubber wheel speeds up to 35,000 to more than 50,000 on the color order . Therefore, if the operator's technology is not mature, or the response to the equipment failure, the processing is not timely, or can not be found in the debugging phase may lead to a large number of printed materials scrapped problems, the commercial waste generated by the rubber tire will be very alarming.

Commercial and semi-commercial rotary machines 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, gentrification, and colorization. , It is often very necessary, but accordingly, lengthened the paper path, so that paper consumption, debugging paper consumption further increased.

High operating costs. Commercial rubber tires have high performance requirements for parts, raw and auxiliary materials, and even lubricating oils. In addition, if additional functions are used together, the operating costs are very high. Therefore, the requirements for various aspects of management 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 rubber “aristocratic” operations.

Improve paper management

After understanding the above characteristics concerning rubber wheel production, scientific management should be carried out 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 rubber wheel paper, the paper roll holder can be made by itself and the core 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. Tested on the Harris 30 Heidelberg V30 semi-commercial 8-color rubber wheel, it can save 30 meters at a time.
