- the temperature media flows in the transfer rollers 10 and 14 are independently controllable in terms of both the quantity and the Temperature of the temperature control medium. Therefore, on the transfer roller 10 is a Temperature level T1 and on the transfer roller
- the distribution of the color streams F1 and F2 depends on the Temperature levels T1 and T2 then as follows:
- Another method for influencing the ink transport in inking units is based on the knowledge that the ink release behavior or the ink acceptance behavior of Inking rollers also depend on the texture or topography of the surface of the Ink layer is determined on an inking roller. It has been shown that a comparatively rough surface of an ink layer on an inking roller in the case of ink splitting in the next nip, the transfer of printing ink hindered and the transfer of ink is reduced. That also means that the undisturbed and thus largely smooth paint layer surface better Ink accepts and thus enables better ink transport. Outgoing A further exemplary embodiment of this is shown below.
