The amount of ink used is usually determined by the size of the graphic and text area of the label, which is designed by the customer, and there is little room for the print labels supplier to adjust. Therefore, how can printing enterprises save costs?
1. Pay attention to the difference between two-layer ink printing and one-layer ink printing
Usually, when printing in a large area, most print labels supplier will print two layers of ink, so as to avoid dirty spots. In fact, there is another reason for doing this: under the condition of the same color density, two layers of thin ink use less than one layer of thick ink.
2. Determine if glazing is required
Glazing has two purposes: one is to increase the gloss of labels, and the other is to protect labels from wear and tear. If only to increase the gloss, flexo printing ink itself has a certain brightness, so there is no need to polish again. If it is to protect labels, there is no possibility that some labels will be worn or polished during transportation and use. It can be seen that glazing labels is actually the inertia thinking of most label printing enterprises. If we do not consider the actual situation, we will blindly choose the glazing process, which will lead to unnecessary varnish loss. Although gloss oil is cheaper than ordinary ink, gloss oil is often coated in full, and the coating is thick, so it is used in a large amount, resulting in waste.
Therefore, in the early stage of the process design, we need to consider carefully, such as whether it is necessary to polish, or whether it is necessary to polish the full version. If the position where the label is attached will not be rubbed at all during labeling, transportation and use, then the ultra-transparent label can not be polished. If it is a special-shaped label, because it needs to die-cut off a large area, then there is no need to polish the full version, only local polishing is needed. For the parts needing polishing, the thickness of polished oil layer should also be considered to meet the requirements of customers. For labels with wear-resistant requirements, it is necessary to ensure sufficient gloss oil thickness, and sometimes it is even necessary to add some wear-resistant additives to gloss oil. In a word, it is enough to meet customers' needs, and there is no need for super-quality and super-cost. Adding unnecessary processes will cause waste of resources.
