Production process: pre-press
Scheme name: Clean production scheme for ink prepress management
Scheme classification: process improvement
Before improvement:
The traditional methods do not pay enough attention to the prepress management of inks. Most manufacturers use manual management, and there is a lack of a more complete and standardized management control system in terms of environmental safety, color standards, proofing systems, inventory control, usage records, and information systems. The cost of ink only accounts for a small part of the total cost of printed matter, but if there is a problem with ink management, it will cause a lot of waste in the process of paper processing, and even be exposed in the downstream link of the value-added chain.
Improved:
The use of computer management system and automatic product distribution system is an important means to improve the management level of ink room. Most printing companies and ink rooms should be equipped with 1-2 technical management personnel, who should be responsible for supplying ink to the printing press. In addition, they are also responsible for color standards, purchasing inks, managing inventory lists, managing waste film, summarizing waste reports and summarizing usage records. And the most important record of the use of total volatile organic compounds (VOC).
(1) Pre-press ink processing: Pre-press ink processing refers to a series of steps and procedures before the ink room technicians purchase the ink and distribute the ink to the printing press operation team. Each company should formulate perfect operating rules so that ink room technicians can clarify their responsibilities, communicate well with personnel in other processes, and fully understand the difficulty of their jobs, so as to properly manage inks and optimize them in an optimized manner. Provided to the printing press operation team, in order to meet the production needs.
(2) Ink room design: The ink room should maintain close contact with ink manufacturers by means of a computer network system, and also establish a digital liaison system with the production, management and sales departments of the company.
(3) Ink room management system: Regardless of the printing method, actual use, and type of printing machine, the ink room must establish a complete system that can control all key processes. A clean production printing company's ink room should develop a complete management and control system in terms of environmental safety, color standards, proofing system, inventory control, usage records, and information system.
The automatic dispensing system for ink mixing has several advantages:
â‘ Ink production implements just-in-time production system (JIT) automatic distribution system can help printing and paper processing enterprises to provide ink for each printing task in a timely and quantitative manner. â‘¡ The supply of each order is more accurate. In the past, the ink ordered was always more than the actual demand. Because I worry that many accidental factors will cause the consumption of ink to exceed the budget. With the automatic ink distribution system, when ink is needed, just press a button to add ink. This is extremely beneficial for reducing the recycling of used ink. â‘¢ Stable quality. The automatic distribution system has extremely high repeat accuracy and can easily handle repeated orders. In this way, the chance of color adjustment and the probability of waste products are greatly reduced, so the ink inventory can be further reduced.
The effect of energy saving:
The use of an ink distribution system with a certain level of computer control and automation can better control ink quality and improve the level of clean production. Printing and paper processing companies that install an automatic ink distribution system can minimize non-production time of the printing press and can significantly reduce ink recycling. At the same time, the system also enables the recovered old ink to be quickly reused. The automatic ink distribution system can calculate the amount of various components required to mix a specific color of ink, and accurately quantify these components.
Notes on the implementation of the program:
In addition, the ink room should do a good job of pre-printing management and improve the ink room technical process level in color management, color measurement, instruments, color matching steps, proofing, ink mixing adjustment tolerance, etc. This improves the pre-press ink management level, which can guarantee the post-printing quality and reduce the overall cost.
Investment amount and payback period:
RMB 2 million to 3 million, with a payback period of 3 to 5 years.
