Leather comes from animals, which determines the irregularity of leather. In addition, the price of leather is high and cannot be wasted, so the leather printing equipment cannot copy the textile printing equipment. At present, printing equipment in leather industry is divided into direct printing equipment, transfer printing equipment and some auxiliary equipment.
A. Direct printing equipment: Of course, the first choice is to lift the plate manually. It has the advantages of fast pattern change, wide adaptability, convenient color registration, etc. However, the biggest problem with the manual lifting plate used for leather printing is the large amount of waste caused by the irregularity of leather. The professional term is "pasting", which needs to be repaired with scissors. Therefore, the manual lifting plate is not used much in leather printing.
The most common leather printing machine is the drum printing machine. The special drum printing machine for leather developed by South Korea can print any fine pattern with excellent printing effect. The utilization rate of leather can be maximized without waste. In addition, there are drip molding machines and embossing machines.
B. Transfer printing equipment: transfer printing requires a paper printer and a heat transfer machine. At present, film is used to replace paper in foreign countries, so a film printer can also be used. The heat transfer machine is different from that of textiles. It requires high pressure. The normal working pressure is 20~30kg/cm2. Generally, oil pressure is used. The temperature requirement is not high. The maximum temperature is 120 degrees. 80 degrees is enough for ordinary people.
C. Auxiliary equipment: auxiliary equipment is the key equipment of the leather printing factory, which is related to the product category and market share.
