There are two principal problems caused by electrostatic charges. The tampon, a silicon based product, touches the product to be printed. Due to the deformation of the tampon, a static charges is created and fine paint splashes may be found on the product or on the tampon. An anti-static bar neutralises the tampon on its way to and from the printing block and will resolve this problem. Contamination on the surface of the product, attracted by static, may be picked up by the tampon and remain stuck, resulting in misprints for all following products. An air supported anti-static bar cleans the product prior to printing, this will provide in better printing and less rejects.
A type MEB shockless anti-static bar combined with an airknife come in standard lengths. The compressed air is blown across the high-voltage points over the entire width and amplified by the ambient air carried along. The air flow is saturated by the positive and negative ions produced by the anti-static bar.
This type of anti-static bar, a more powerful version of the EP-Sh-N is highly effective and, with its long range, ideal for neutralization of static electricity on materials when the distance varies. Under certain conditions the maximum distance may even be as large as 600 mm.
