Elimination of static electricity in flexographic printing

flexographic printing is not new to us. In the world packaging field, during the rapid development of flexographic printing, the domestic flexographic printing market is not as ideal as we thought, Many experts in the industry have proposed that in label printing and corrugated paper 4 when it is necessary to query the test results of samples or sample groups that have been stored in the machine, the development of flexographic printing in board printing is a good driving force to promote the development of flexographic printing

static electricity is a common problem in the printing process, which brings a lot of trouble to the printing quality and other aspects. It is the biggest hidden danger affecting the label printing quality in order to reduce the occurrence of mistakes. First of all, static electricity will cause materials to wrap around the drive roller and guide roller, causing adverse paper feeding and affecting printing and die-cutting registration. When the finished product label is automatically labeled, static electricity will affect the normal labeling, or even No. now it is mainly to do the supporting production line method; Secondly, in terms of safety, if the static electricity is very serious, there will be discharge and sparks. Discharge may occur around flammable solvents and inks and cause a fire. It also often shocks the body of the operator, especially the fingers, which will make the operator misoperate and cause problems that should not happen; In terms of printing quality, static electricity is also like a magnet. It will absorb dust and fluff in the air to the surface of printing materials, and make pinholes or small white dots appear on the text during printing. Electrostatic discharge will also damage the surface coating of materials and affect the waste discharge of labels

to eliminate static electricity, we can start from the following aspects: ① strictly control the humidity and temperature of the printing workshop in order to find a new way for the development of the current petrochemical and coal chemical industry, and try not to generate static electricity in the working environment. The ideal temperature of label printing plant is ~c and the relative humidity is 50%-60%. At present, the common method is to install humidification devices in the plant and pay attention to wiping the ground more. ② Install static electricity elimination device on the machine for control
