After printing, the remaining ink should be filtered and sealed and placed according to the color classification, and the label and color sample should be pasted on the packaging barrel to indicate the color ratio, so as to facilitate the use in the next production or color matching when similar colors are produced. The surplus of old ink in spot color is a headache for many printing factories, especially for the manufacturers specializing in surface printing and packaging. I have visited many printing factories. Some manufacturers have a lot of old ink inventory, but some of them are well controlled. This involves a problem of old ink management and digestion.
① When matching spot colors, the quantity should be well controlled. First, make a small test, and then adjust it to meet the amount of ink on the machine. After the effect is OK, mix it according to the calculated ink amount.
② Get the color sample, in the deployment of spot color, as far as possible in the old spot color ink to find the color similar ink, and then add some new ink to mix. If you use new ink every time, we all know that after a period of time, the saturation of the ink decreases, that is, it is not as bright as the new ink, and becomes old ink. In this way, not only the old ink can not be digested, but also more and more.
③ General manufacturers reflect that the old ink is difficult to digest. The original reason is that the color is not bright enough and the color concentration is low, which can not achieve the original effect. They have to use new ink, and even the new ink can not achieve it. They want the ink manufacturer to provide high concentration ink. This is the proofing is not well controlled, in order to achieve a certain effect and all use new ink printing, even in order to achieve the effect of viscosity, as the ink aging and darkening, the plate wear is very difficult to achieve the original effect, which is why so many old ink due to lack of brightness, color concentration and can not digest. Therefore, in proofing, it is necessary to consider normal production in the future.
