Static/Anti-Static Cleaning Cleaning

TheFlexoFactor offers the ROTOSTATIC "Top Loading" system, at the inlet side of the printing unit, the material to be printed (paper or film) is neutralized by the first ACE antistatic bar, type BN, with a strong de-ionizing effect, in order to eliminate any static electric charge that may be present.

TheFlexoFactor Static/Anti-Static image After this, the special static bar type DE R40, located above the pressure roller creates an intense, homogeneous electrical field in the semi-conductive layer of the sleeve/rubber pressure roll itself. The electrical field is then transferred from the pressure roller to the impression cylinder so as to guarantee a specific polarization of the ink present in the cells, and consequently a perfect transfer onto paper or film to be printed. The second antistatic bar, type BN, with a strong de-ionizing effect is positioned at the outlet side from the printing unit, so as to eliminate completely any static electricity present in printed material.



TheFlexoFactor offers the ROTOSTATIC "Direct Charging" system, at the inlet side of the printing unit, the material to be printed (paper or film) is neutralized by the first ACE antistatic bar, type BN, with a strong de-ionizing effect, in order to eliminate any static electric charge that may be present.

TheFlexoFactor Static/Anti-Static image After this, with the DC 50 (direct charging system) the charging of the sleeve/rubber pressure roll is made directly from the core and then transferred to the external semi-conductive surface. The electrical field is then transferred from the pressure roller to the impression cylinder so as to guarantee a specific polarization of the ink present in the cells, and consequently a perfect transfer onto paper or film to be printed. The second ACE antistatic bar, type BN, with a strong de-ionizing effect is positioned at the outlet side from the printing unit, so as to eliminate completely any static electricity present in printed material.



The "Missing dots" is an extremely common quality problem in rotogravure printing; "missing dots" are those points in the print where the ink (having been only partially emitted from the cylinder cells) has not been perfectly TheFlexoFactor Static/Anti-Static imagetransferred to the substrate (paper or film) to be printed.

The Rotostatic system of "electrostatic printing assist" guarantees complete and accurate ink transfer to paper or film, even at higher production speeds, without the need for excessive roller pressure.
