METHOD FOR THE INDIRECT APPLICATION OF PRINTING LIQUID ONTO A PRINTING MATERIAL

摘要

A method for the indirect application of printing liquid onto a printing material provides an intermediate carrier, preferably a circulating belt, a liquid conditioning medium including a first substance applied onto the intermediate carrier and a printing liquid, in particular an inkjet ink, including a second substance applied onto the conditioning medium on the intermediate carrier. The printing liquid is situated as droplets or a layer substantially on the conditioning medium and the droplets or the layer form a contact region on their underside with the conditioning medium. The printing liquid is heated, preferably by way of a dryer and the printing liquid is transferred from the intermediate carrier onto the printing material.

1. A method for the indirect application of printing liquid onto a printing material, the method comprising the following steps:
providing an intermediate carrier; applying a liquid conditioning medium, including a first substance, onto the intermediate carrier; applying a printing liquid, including a second substance, onto the conditioning medium on the intermediate carrier; situating the printing liquid as droplets or a layer substantially on the conditioning medium, and forming a contact region on an underside of the droplets or the layer contacting the conditioning medium; heating the printing liquid; transferring the printing liquid from the intermediate carrier onto the printing material; forming a film of the printing liquid in the contact region resulting from the first substance of the liquid conditioning medium increasing a viscosity of the printing liquid on the intermediate carrier in the contact region by way of a reaction with the second substance of the printing liquid; and providing the printing liquid with a lower viscosity outside the contact region than inside the contact region.
