In label printing, the following issues should be noted:
(1) Use the same brand of ink produced by the same ink manufacturer to avoid printing failures of different manufacturers and different types of ink mixed.
(2) The ink is fully stirred before use, and it is often stirred during the printing process to ensure that the ink system is evenly dispersed.
(3) Don't mix too much ink each time. It should follow the principle of "less and diligently adding", which is not only conducive to the stability of ink performance, but also effectively avoiding waste. In addition, for spot inks, it should also be prepared recording.
(4) In the printing process, in order to ensure the quality of the label printed matter and the smooth progress of production, certain additives should be added to the ink, such as antistatic agents, defoamers, and adhesive removal agents, and the amount must be controlled Within the specified range.
There are many deficiencies in label printing inks in the Chinese market. The most prominent problem is the problem of ink hue deviation. On the one hand, the hue of the same ink produced by different ink manufacturers is different; on the other hand, even the same ink produced by the same manufacturer is different. , Different batches, the hue will also deviate, sometimes even large. For this reason, printing plants often have to shut down and debug, which is very detrimental to the stability of print quality, which brings great inconvenience to production and seriously hinders the improvement of print quality.
There is still a certain gap between domestic inks and imported inks, especially in high-end products. Domestic ink manufacturers should improve their technical level and production capacity as soon as possible to promote the improvement of the entire ink manufacturing industry.
In order to achieve a better preservation effect, the label printing ink should be stored in a closed container under normal temperature, cool, dry, dark, and ventilated environment.
