Post press technology: attention to details of die cutting summary

1. Due to the lack of understanding of customers' requirements on the performance of printed matter, high-grade materials are selected in production, but in fact, as long as medium and low-grade materials are selected, they can meet the requirements of customers

2. Because customers don't understand the performance of materials, they blindly make some hard requirements for label manufacturers (such as material numbers specified abroad), resulting in unnecessary cost increases

for the first case, the salesperson should strengthen communication with the customer, understand the customer's requirements on product performance and other aspects, and let experienced technicians check it, so as to avoid overusing

for the second case, the printing factory should make more efforts in coordinating with customers and persuade customers through appropriate methods, which may encounter a lot of resistance, but it is very important to reduce costs

in addition, without special requirements, some label printing manufacturers choose joint venture materials or ISO certified materials. The reason why they do this is mainly considering that these materials have good properties, which I believe is the most credible, It can meet the requirements of label printing, and it is easy to reach an agreement with customers. It is simple and convenient to choose. However, to better achieve the purpose of reducing costs, when printing labels of different grades, different grades of ink, paper, self-adhesive and other materials can be used to effectively control the waste in the process of label printing

reasonable selection of printing methods

in the face of various distinctive printing methods, in order to reduce equipment debugging time, improve production efficiency, improve product quality to a certain extent, and meet the needs of customers, label printers often classify products according to different grades and batches of live parts, and then choose different printing methods for printing

at present, China's label printing is mainly embossed, offset and silk printing, while developed countries such as Europe and the United States mainly use flexographic printing. With the continuous improvement of domestic plate making level and the continuous reduction of price, the comprehensive cost of flexographic printing will be greatly reduced, and its characteristics of low input and high output will attract more and more label manufacturers. In the long run, flexographic printing will be the first choice of packaging printing, especially label printing. In the field of label printing, combination printing is more and more favored, one of the reasons is that it can complete printing and post-processing at one time, which not only improves the production efficiency, but also greatly reduces the label printing cost

in addition, when the printing method is selected, if the machine adjustment method is appropriate, it can also reduce material waste and machine loss. For example, when printing high-end labels, first debug the machine with ordinary and cheaper special gloss paper, and then replace it with better materials for printing; Start the machine at medium speed when debugging, and then speed up the machine after debugging; Proofread the color while proofreading the pressure of the printing plate, and then proofread the color after these two steps are completed

pay attention to details of post press die cutting

when offline die cutting is adopted, inaccurate die cutting often occurs, which may even cause a large number of labels to be scrapped, and the machine must be shut down for debugging. If the inspector does not master the die cutting standard, it will also increase the printing cost

in addition, in the printing of some self-adhesive labels (especially some small area labels), waste adhesion often occurs during die-cutting and waste discharge processing, which is also one of the main reasons for the waste of printing materials. It is suggested that the following methods can be adopted

1. when designing the label, the area of the label can be appropriately increased, and the shape of the label should not be too complex, and a reasonable arrangement should be adopted

2. Appropriately reduce the temperature of the self-adhesive material storage workshop and the printing workshop to prevent the viscosity of the adhesive on the paper from decreasing

3. replace the die-cutting blade that has been used for a long time and the blade is blunt, or glue the sponge between the die-cutting plate and the blade, or make the die-cutting plate again

4. Adjust the pressure of the die-cutting plate by padding the die-cutting bottom plate to make the pressure of the die-cutting plate uniform and the depth of the die-cutting indentation consistent

5. Improve the speed of die cutting waste discharge

scientific management and strict control

in order to reduce the cost of label printing, in addition to making more efforts in various process links, we should also actively promote standardized and digital management. Domestic label printing enterprises should establish new management concepts and new management systems while introducing new equipment, new processes and new technologies, so as to comprehensively improve the quality of label production and reduce costs with scientific and standardized management. Tianjin lindco Industrial Co., Ltd. has provided us with a good example in this regard after more than 10 years of hard work in academia and business circles. Figure 1 shows the current management mode of the company. According to the relevant person in charge, this management mode has played a great role in reducing production costs, especially in the management of new products

determine product requirements

review product requirements

production preparation

formulate production plan

product production implementation

finished product inspection

product delivery

in short, a scientific management mode can organically combine all process steps of label production to realize the overall control of the production process


reducing the cost of label printing is an overall work, and the key is to make a reasonable overall plan in the prepress design stage, taking into account the process characteristics of each process. Through scientific management, everyone admires our manufacturer's technology as a whole, and reasonably controls label printing, so as to ensure quality and reduce waste at the same time

throughout the production process, the coordination between label printing manufacturers and customers has been running through it, affecting every link of label printing. For customers who have made clear requirements, the label printing manufacturer should try to coordinate the relationship between production and customer requirements according to the actual situation of the factory, so as to minimize the label printing cost by the national production and experimental machine factory of Jinan new era assay instrument Co., Ltd
