In printing and coating processes as well as in roller inking units of printing presses so-called ink mist or particle mist is generated in the outlet of double roller systems, coming from the appropriate coating material resp. the printing ink. The MISTING TACKER MTS20 system is designed to reduce ink mist in the printing / application nip of printing and coating units. The patented dual DC plasma bar R170A3 imparts separate charges to the particle streams, ensuring optimal particle separation. The benefits: • complete particle deposit on the roll surface or on the substrate • reduced ink and coating consumption • less pollution of the environement • optimal print/coating results at the highest processing speeds and lowest maintenance costs • less maintenance effort Technical Information MISTING TACKER SYSTEM MTS20 System for the reduction of ink mist in printing and coating units

System Description MISTING TACKER SYSTEM MTS20 by Eltex In the application units of coating systems and in the inking units of printing presses, the ink or coating is split, distributed and transported by a series of roller pairs. The printing/coating substrate is transported in the nip between the application roller and the impression roller. At increasing processing speeds, the ink/coating is split into more than two parts, leading to free particles. The particle streams formed in the outlet have a wide particle size range; their diameter ranges from a few nanometers to a few micrometers...

Protective Circuit, Enable Signals For each coating unit a protective circuit with the following functions (see figure) must be realized. To guarantee the safe operation of the system in the coating unit even under explosion-hazard conditions, the following enabling conditions must be observed. Release Discharge — Washing unit active — Web feed active Coating unit engaged — Minimum speed v >0 Release Charge — Web break Emerging stop — Impression cylinder in working position Minimum speed v >0.4 m/s 1,2,3,4: Input analogue interface Power supply ON when master switch of machine ON Housing...

Impression Cylinder Contact High voltage should not be enabled before a safe electrical contact is made between impression cylinder and transfer roller! For the lift-off of the impression cylinder the protective circuit must be designed such that the enabling mechanism of the high voltage is switched off before the impression cylinder lifts off, i.e. before there is no longer any contact with the substrat and the transfer roller This can be implemented by one of the following methods: • use of hydraulic or pneumatic pressure switches which respond to the increase in pressure (back pressure)...
