How does the offset printing collar (captain) do the collar job?

Each crew, one squad is a combat collective, the pilot is the commander of the crew, and is also a combatant. It is a small unit of product and quality. Every day the crew work is conducted under the command of the pilot, in order to further Improve the quality of the pilots and the crew, better complete the production tasks, put forward some of my work experience for the reference of counterparts.

First, the collar quality function

Product quality is the life of a company, and it is also a reflection of the overall management of the work of the crew. Implementing the quality first principle is an important embodiment of each company’s business methods. Printing work is to disseminate scientific and cultural knowledge and enrich the people's spiritual and cultural life. Therefore, we insist on quality first, strengthen quality management, strive to improve the printing quality, and serve the harmonious society and scientific and economic development better. The printing colleagues all know that without good product quality, there is no good economic benefit, the product quality is good, the company's partners are numerous, and business repeat customers are also numerous, that is to say: “Good wine is not afraid of the deep alley”.
The first thought of quality comes from the work style of excellence, and the work style of excellence. It will be able to achieve the goal of seeking for many things in a good manner, seeking for the best in the middle, seeking for the province, and working hard to produce high quality products. task.

Second, love machinery and equipment, abide by the operating procedures

Leading the crew to lead the crew to keep equipment in good condition, do a good job of maintenance and repair of the equipment. The crew is proficient in the use of equipment, conscientiously do a good job of safe production and civilized production, abide by the process and safety operation regulations, according to the printing standards, according to production Notice work, earnestly implement self-inspection and mutual inspection system, respect the inspection opinions of full-time staff, and take the initiative to put product quality into good hands.

Third, continuously improve the application of computer operations

In recent years, the printing industry in Langfang has developed rapidly and the printing machines have become more and more advanced. As computer equipments represented by Heidelberg are more and more, therefore, operators use computer equipment to combine their own work experience to sum up their own The database experience is very necessary. The lead should lead the crew and understand the basic operation methods of the computer console and the related basic parts. The following is a brief introduction of the Heidelberg computer console. The computer operations of other machines are similar.

1. The Spitet of Heidelberg Plant, more than 90% of Maastricht Multicolor Machines are sold with various CPC systems, among which CPC1 is the most basic electronic remote control system. On the CPC1 console, the operator can see the light emission. The ink is displayed on the 32 ink zones displayed by the diode. (Each ink zone has a 32mm-wide small eccentric roller that is pulled by a micro servo motor according to the electronic signal to change its pressure on the sheet so as to adjust the gap between the sheet and the ink roller)

2. Each ink zone CED is displayed in 16 levels. There are two buttons below. The operator can take a copy of the proofs and compare the proofs of their own printed products. If the ink color of a certain area is found dark, press the down button of the area. The small eccentric roller in this area will press the electronic signal to the ink roller accordingly, and the ink will quickly become light. If the ink is found to be light, press the button on the area, then the small eccentric roller in the area will correspond to Releasing the sheet to the ink roller to increase the amount of ink, the ink quickly becomes darker.

3, the other main function of the computer console is to control the accuracy of overprinting, fine-tuning up and down, left and right, the operator does not have to adjust the shades of ink, or overprinting is not allowed, tired to climb up, jump down, so as to greatly reduce labor Intensity reduces the scrap rate, reduces downtime and saves paper consumption, but the system has to rely on the operator's judgment and push buttons to adjust, it only plays a role in remote control.

In order to better use the computer, the leader should work in accordance with the ink density data standard and sample quality of the Qichang plant and lead the crew in the long-term computer operation, constantly establish their own database experience, have their own database Experience, no matter what kind of printing products, as long as you see proofs, you can do the ink pre-adjustment work, computer data is basically in line with the proofs of the ink density standards, if there are individual differences in the printing, and then make individual adjustments, this will save a lot The edge of the ink to find ink time, will also save a lot of paper consumption, to establish their own database operation method is:

1 Ink density + dot layer + area occupied by inks 2 Ink volume of the ink fountain is adjusted first, and data for each ink zone is adjusted again

Fourth, strict implementation of the five-phase six printing process during the printing process

　　 (Five diligent)
1. Diligent proofs 2. Check the rules and regulations 3. Check the water and ink level 4. Check if there is any dirt or dirt 5. Check whether the equipment is abnormal

(six without printing)
1, the rules are not good, not allowed to engage in not printing, 2 wire drawing network points are not true, large unevenness is not printed 3, ink is not correct not printed 4, does not meet the proofs are not printed 5, large land has white spots, ink spots are not India 6, found problems or doubt not printed

V. Conduct QC group activities and implement scientific management

Leading leaders led the crew to actively carry out QC group activities, implement scientific management, and apply the eight steps of the PDCA cycle to properly resolve contradictions among people, machines, raw materials, and quality requirements, and to prevent product defects in the production process, and strive to improve qualifications. Products and high-quality products, continuously improve product quality and economic efficiency, improve scientific management, and build units into economical units, united and cooperative units, high-quality and high-production units, and scientifically managed units.

Here's a brief introduction of what is the characteristic of the PDCA cycle

PDCA cycle, that is, according to the work or assumptions to arrange the work plan, in accordance with the plan implementation, in the implementation process of inspection and adjustment, when the implementation of the plan is completed, before and after processing, this general rule of doing things by the American "declaration "This is called PDCA cycle, that is:
P - Plan D - Perform C - Check A - Process

feature is:
1 large ring sets of small rings, a ring buckle, a small environmental protection ring, to promote the major cycle.
2 The management cycle is a comprehensive cycle. The key to promoting the PDCA cycle is Phase A.
3 The management cycle is increased by one step per rotation.
Through the QC group activities, the crew's work production has been continuously improved, and the relationship between quality and quantity, economy and ideology, responsibility and solidarity, security and cooperation has always been correctly handled. This has made the crew become a political democracy and harmonious, economic and democratic mutual concessions, and technological democracy have improved. Excellent crew.
