The main factors affecting the printing quality of self-adhesive labels are composed of consumables, printing equipment and printing environment. These factors all have one thing in common, that is, they can be required and stipulated by objective evaluation method.
1. Printing equipment
Including the normal operation rate of related equipment in the production process, the input of various auxiliary equipment and whether the mutual matching relationship meets the requirements will have a certain impact on the quality of printed products. If the equipment fails frequently, it will not be able to fully play the functions of the equipment, and the semi-finished products processed by printing or other processes will also have various quality problems, so that the final quality of the label cannot be guaranteed, and this is the guarantee of the equipment. The key to uptime. In addition, some equipment also has certain requirements for objective factors such as the environment during use. If these requirements are not met, the quality of the label will be directly affected. It can be seen that ensuring the normal operation of the equipment is conducive to ensuring the quality of printed labels.
2. Printing consumables
Printing consumables, including label raw materials, inks, plates, and fountain solutions, will have different properties, and these properties will directly affect the printed labels. Before printing, it is necessary to master the performance and printing suitability of various consumables, in order to avoid factors that may affect printing, and to promote the characteristics that have a positive effect on printing. Many printing products have different requirements for printing effects. Some have strict requirements on the color of label printing. The requirements for various labels are different. Because customers have different requirements for printing labels, it is necessary to choose the right one. raw materials. Only when some external factors that affect the quality of printed labels are fully considered, and the advantages are fully utilized in the production process and defects are overcome, the quality of printed products can be improved to a certain extent.
3. Printing environment
The so-called printing environment includes environmental factors such as environmental temperature, humidity, dust, and the presence or absence of light in the production process of printing and other processes. These factors will affect the quality of printed labels in each process. Changes in the environment will have a certain impact on printing. Changes in temperature and the degree of dust in the printing environment also have a certain impact on the properties of ink and paper in offset printing, which will affect the drying of the ink layer on the surface of the printed product and the uniformity of color, etc. Quality requirements have different degrees of influence, resulting in different degrees of reduction in the quality of printed labels.
In the process of printing labels and various processes of processing printed labels, it is necessary to ensure the constant temperature and humidity of the environment and reduce the dust level in the air, so as to ensure the stable quality of the final printed products. In short, to ensure the stable quality of printed labels, it is necessary to avoid the adverse effects of adverse factors on printing quality in actual production, and to fully explore the promotion of favorable factors. Only in this way can the quality of printed labels be stable.
