The problems with the label printing process are the main problems that currently affect the label yield and the consumption of consumables. Solved these problems, the yield rate increased, the consumption decreased, and the profit margin increased. Otherwise, label printing companies are faced with constantly compressing the profit margins of labels, wandering on the original management level. Let's discuss the problem of consumables in label printing.
1. Selection of self-adhesive materials
When label printing companies choose self-adhesive materials, they mainly rely on experience accumulation and trust in suppliers. Many key factors related to the quality of the label product, such as the type of adhesive, the type of face material, the thickness of the glue, the stiffness of the material, etc., are not well understood and poorly understood. Label printing companies have to pay for the losses caused by the self-adhesive materials.
Second, the curing problem of UV ink
A series of problems often occur during label printing, such as UV ink ink layer curing is not transparent, and the ink film does not reach the expected design resistance. However, there are currently unresolved UV ink curing standards in printing companies, which makes the first-line captains dare not increase the speed when printing, which directly affects the printing capacity, making the situation of low UV curing efficiency and large energy consumption difficult to change. The new LEDUV device has the same effect.
UV curing has the following characteristics:
1. The spectrum of the high-pressure mercury lamp deviates significantly from that of the photoinitiator in UV products, making it difficult to achieve high efficiency.
2. The factors involved in UV curing ink curing include prepolymer, monomer, photoinitiator, etc.
3. Warm-color UV inks are easier to cure than cold-color inks, and thinner ink layers are easier to cure than thicker ink layers.
The above introduces the problem of consumables in the label printing process, I hope to help everyone.
This is a paper Slitting Machine used to slit the big paper roll into many small paper rolls. The small paper rolls will be put on Paper Rope Machine to make the different twisted Paper Rope or Flat Paper Rope and used on Paper Handle Machine to make the different handles. It is a very good supporting machine for paper rope or Paper Handle production. It is running stably, smoothly and fast.
