1. Strict selection of raw materials
To ensure the appearance quality of Blank Labels, we must first start with the selection and inspection of raw materials. For the basic materials of labels, whether it is paper, plastic or composite materials, we must choose suppliers with reliable quality. When the raw materials enter the factory, we must conduct strict sampling inspections. Check whether the surface of the material has defects, such as whether the paper has uneven fibers and holes, and whether the plastic material has scratches and bubbles. Physical properties that may affect the appearance, such as the color uniformity of the paper and the transparency of the plastic, should also be tested. Only raw materials that have passed the inspection can enter the production line, reducing the possibility of appearance problems from the source.
2. Control of the production environment
The production environment has an important impact on the appearance quality of Blank Labels. The first is the control of temperature and humidity, because different materials may deform, absorb moisture or dry too quickly under different temperature and humidity environments. For example, paper is prone to moisture and wrinkling in a humid environment, so the production workshop should maintain a suitable temperature and humidity, generally controlled at 20-25 degrees Celsius and relative humidity at 40%-60%. The second is cleanliness management. It is necessary to reduce dust and impurities in the workshop, because dust particles may adhere to the surface of the label material, causing stains on the label. Keep the production environment clean by installing air purification equipment and regularly cleaning the workshop.
3. Maintenance and adjustment of production equipment
The state of production equipment is directly related to the appearance quality of Blank Labels. Regularly maintain and maintain cutting equipment, printing equipment (if there is a pre-printing process), etc. to ensure the accuracy of the equipment. For example, the cutting tool of the cutting equipment should be kept sharp, otherwise burrs may be generated when cutting the label. For printing equipment, the surface of the printing roller should be smooth to avoid leaving marks on the label. At the same time, according to the size and production requirements of the label, the parameters of the equipment should be accurately adjusted, such as the cutting size of the cutting equipment and the pressure of the printing equipment. The stable operation and precise adjustment of the equipment can effectively prevent the appearance problems of uneven cutting and printing ghosting on the label.
4. Inspection and packaging of finished products
After the production of Blank Labels is completed, strict finished product inspection should be carried out. A combination of manual inspection and automated inspection equipment is adopted. Manual inspection can reveal some subtle appearance problems that are difficult to detect with automated equipment, such as slight scratches or inconspicuous wrinkles on the label surface. Automated inspection equipment, such as optical inspection systems, can quickly and accurately detect appearance indicators such as dimensional accuracy and color consistency (if there is a color mark) of labels. Blank Labels that pass the inspection should be properly packaged, and appropriate packaging materials should be selected to prevent the labels from being squeezed, rubbed, etc. during transportation and storage, thereby ensuring the final appearance quality of Blank Labels.
