The core factors of sticker production are quality, delivery time and wear and tear certification, which are interdependent and contradictory. For example, if the quality requirement is high, the loss may be larger, and the tight delivery time may affect the product quality. So how to coordinate the relationship between the three? The author believes that the following points should be done.
1. Improve inventory management system
Printing companies must reasonably control costs and losses, first of all must understand the actual number of production materials used in each order, and then calculate the production cost of each order based on these data. To achieve this, a strict inventory management system must be established, with specialized personnel responsible for inventory management, including the entry and exit of materials from printing materials to auxiliary materials such as ink and gasoline, and detailed records must be recorded. For the production of non-dry collagen materials should be specific to the actual use of each order, for auxiliary materials at least to the total amount of each month.
Usually we will encounter the problem that the length of the non-dry collagen material cannot be counted clearly. This is because sticker label printing usually adopts a roll-to-roll processing method, and generally uses "meters" as a unit of measurement to calculate the amount of dry collagen material used. A part of the whole roll of material is used, so how many meters are left? The best way is to use the machine for rewinding measurement, but because the printing companies receive and return materials many times a day, this method will greatly increase the workload of the warehouse staff. Here, the author introduces a simple method for calculating the amount of raw materials for adhesive labels. First of all, you can weigh the weight of the entire roll of material and the remaining material separately, and then divide the weight of the remaining material by the weight of the whole roll of material, and then multiply the length of the whole roll of material to equal the length of the remaining material. For example, a 180 mm wide roll of dry collagen material has a length of 1000 meters and a weight of 50 kg. After printing, the remaining material weighs 30 kg. Then the remaining material is about 30/50 × 1000 = 600 meters.
It has been proved by practice that this calculation method is quite accurate. The only drawback is that when the remaining raw material is less than 50 meters, a larger error will occur, because the ratio of the weight of the paper core to the total weight is getting more and more Large, resulting in relatively large errors. Therefore, if an experienced manager encounters a situation where there are only a few tens of meters of raw materials in the printing process, he or she will usually let the operator run out of these raw materials and produce more labels for stock. Because when the remaining tens of meters of material is printed again, it is likely that there will be no connection processing when the machine is adjusted, which is also a waste.
2. Control of loss of raw materials
In terms of raw material loss control, the author's approach is to formulate a uniform loss standard according to the percentage of consumption according to the work items of different color numbers. For example, the pass rate of one-color printed matter reaches 99%, which means that if the one-color job consumes 100 meters of raw material ink, only 1 meter is a defective product, which is the normal consumption in the printing process, plus the printing operator The material consumption for finding a version is the total amount of raw materials that a job should consume. If you do a 3-color printing job. 1200 meters of raw materials are calculated by multiplying the steps and the number of impressions, and then divided by 97% to get 1237 meters. If the acquisition is calculated based on the 5 meters of color for each version, the total planned material for live parts is 1252 meters. . If the actual material exceeds this amount, it is a loss, if it does not exceed, the loss is reasonable.
Of course, due to the particularity of the printing industry, it is difficult to give a very accurate calculation method for the consumption of raw materials. The method described by the author is based on the average characteristics of the long and short jobs of our company. In theory, , It is more reasonable for calculating long jobs.
3. Sample storage and management system
It is believed that the production management personnel of many printing companies have suffered from unstable product quality. To solve the problem of label printing quality, the storage and management system of samples should be established first. The general sample content should include the upper, middle and lower limits of the label color and the specific production process, such as the die-cutting knife plate used, the type of ink (including the proportion of spot color ink), the printing process (step, number of consecutive editions) , Horizontal and vertical spacing, etc.), post-processing technology (rewinding or cutting, the number of labels per roll / each printable, paper core tube diameter, packaging method, etc.). Every time a new job is printed on a newspaper, the process must be clearly written on the sample and issued to the post-process together with the production notice. Finally, the sample is sealed in 3 copies in the post-printing process. The production department and product One for inspection department and one for customer. The sealed samples will be used as the quality standard for the production of the same label print in the future, and also as the acceptance standard for customers.
4. First and last piece signing and inspection system
There are many variable factors in the production process, how to control these variable factors? The printing enterprise should establish the first and last piece signing system and patrol inspection system, that is, at the beginning and end of printing, the operator should intercept the sample and give it to the production management personnel for inspection to confirm that they meet the quality standards before they can start or end production. At the same time, in the production process, there must be special patrolling personnel to monitor the quality of the product at any time to ensure the stability of the product quality. [next]
5. Formulate reasonable output standards
The establishment of reasonable output standards is the first step in the rational control of production capacity. Each printing enterprise may have multiple types of machinery and equipment, and the enterprise's managers must formulate according to the characteristics of these equipment (such as old and new conditions, operating speed, printing principles), the technical level of operators and the difficulty of jobs. Output standards.
The author establishes the output standard in this way, first selects a new equipment or the equipment in the best operating state, allows the best employees to operate the machine, writes down the daily output plate, and takes this output as the highest standard. Then gradually reduce the output according to the wear of other similar equipment and the level of personnel operation, so that several different output levels can be obtained.
6. Reasonable deployment of production schedule
(1) Arrangement of long and short jobs
For long-form jobs, try to arrange equipment with fast printing speed and good performance for printing, which can save man-hours and improve efficiency; for short-form jobs, the printing can be done by slower equipment.
(2) Workpieces of the same color should be arranged together as much as possible
In the production process, it should try to arrange the same-color work pieces to be printed together, which can reduce the number and time of ink washing, and greatly improve production efficiency. This is because it is a waste of time to wash the ink and change the color during the printing process, especially when the dark color ink is changed to the light color ink, it often takes an hour or more, so try to arrange the same color system. The pieces are printed together.
(3) Try to arrange jobs with the same specifications
Printing companies often have labels with the same specifications, and their cross-cutting blades can be shared. Therefore, in the actual production of printing accessories, labels of the same specifications should be arranged on the same equipment for printing, so as to reduce the time for changing the die cutting plate.
(4) Some common products should be kept in stock
For some small batches, but often need to repeat printing jobs, you can prepare some inventory after communicating with the sales department. In this way, when the exhibition receives the same order from the customer, it can be directly called from the inventory, which not only saves the production cost, but also provides a guarantee for shortening the delivery time.
Zipper Printing
Zipper Printing is the process of printing designs or logos on zippers. This is usually for promotional or branding purposes, such as adding a company logo to the zipper of a jacket or backpack. The printing process usually involves the use of a special ink that is applied directly to the zipper material. The ink is then cured or dried with heat or UV light to ensure the design is permanent and won't rub off over time. Zipper printing can be performed on a variety of zipper types including metal, plastic and nylon zippers.
