1. Because we do not understand the customer's requirements for the performance of printed matter, high-grade materials are used in the production, but in fact, only the medium and low-grade materials can meet the requirements of customers.
2. Since the customer does not understand the performance of the material, blindly making some hard requirements for the signing manufacturer (such as the material number according to foreign regulations), resulting in unnecessary cost increase.
For the first case, the business personnel should strengthen communication with the customer to understand the customer's requirements for product performance and other aspects, and let experienced technicians check to avoid overkill.
In the second case, the printers should work harder to coordinate with the customers and convince the customers through appropriate methods. This may encounter a lot of resistance, but it is very important to reduce costs.
In addition, in the absence of special requirements, some label printing manufacturers use "joint venture materials" or materials that have passed ISO certification. The reason for this is that the materials are better in performance and can meet the requirements of label printing. It is easier to reach agreement with customers and it is simple and convenient to select. However, in order to achieve better cost reduction, when printing labels of different grades, different grades of ink, paper, and other materials can be used to effectively control the waste in the label printing process.
Reasonable choice of printing method
In the face of different printing methods, in order to reduce equipment commissioning time, improve production efficiency, and improve the quality of products to a certain extent, to meet customer needs, label printing manufacturers often according to different grades and different batches of work, the product After categorization, different printing methods are used for printing.
At present, China's label printing is mainly embossed, offset and screen printing, while developed countries such as Europe and the United States mainly use flexographic printing. With the continuous improvement of the domestic plate making level and the continuous reduction of prices, the comprehensive cost of flexographic printing will be greatly reduced, and its low input and high output characteristics will attract more and more label manufacturers. In the long run, flexographic printing will be the first choice for printing, especially for label printing. In the field of label printing, combined printing is becoming more and more optimistic. One of the reasons is that it can complete printing and post-processing at one time, which not only improves production efficiency, but also greatly reduces the cost of label printing.
In addition, when the printing method is selected, if the tuning method is correct, the material waste and the loss of the machine can be reduced. For example, when printing high-grade labels, first use ordinary, cheaper special light paper to debug the machine, and then replace it with better materials for printing; start the machine at medium speed when debugging the machine, and speed up the machine after debugging; At the same time, the color of the plate is set, and the color is corrected after the two steps are completed.
Post-press die-cut attention to detail
When using offline die-cutting, die-cutting is often inaccurate, and even a large number of tags may be scrapped, and debugging must be stopped. If the inspector masters the poor die-cutting standards, it will also increase the cost of printing.
In addition, in the printing of some self-adhesive labels (especially some small-area labels), the label is often stuck in the die-cutting and waste-discharging process, which is one of the main reasons for the waste of printing materials. The suggestion can be solved as follows.
1. When designing the label, the area of the label can be appropriately increased, and the shape of the label should not be too complicated, and a reasonable arrangement is 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 self-adhesive material surface paper from decreasing.
3. You can also re-make the die-cutting plate by replacing the die-cutting blade that has been used for a long time and has a blunt edge, or by sticking a sponge between the die-cutting plate and the blade.
