  • Patent number: 10336060
    Abstract: An aqueous ink transfer process includes coating the surface of an image transfer member (ITM) with a coating composition to a first thickness, the coating composition including a hydrophilic composition and a surfactant, partially drying the coating composition to reduce its thickness and then applying aqueous ink onto the coating composition. The coating composition in the vicinity of the applied ink swells by absorbing water from the ink, and can further exhibit reduced adherence to the ITM. The ink is partially dried and then transferred onto a substrate.

  • Patent number: 10252548
    Abstract: A method for manufacturing printed products contains the steps of applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process. An essentially colorless and water-containing liquid is applied a) to non-image regions and/or b) to image regions that have only little ink in the drop-on-demand process. The printing material is dried. The printing material has a coating that contains at least one acid. After the application of ink and the application of a liquid, a water-containing further liquid, for instance a varnish, is applied both to image regions and to non-image regions of the printing material, and that the liquid and/or the further liquid contains at least one substance that at least partly neutralizes the acid. The undesired formation of waves and glossiness fluctuations between varnished image regions and varnished non-image regions may thus advantageously be avoided.

  • Patent number: 10252549
    Abstract: A printed product is produced by applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process, applying a substantially colorless and water-containing liquid a) to non-image regions and/or b) to image regions that have little ink in a drop-on-demand process and drying the printing material. In this case, the printing material has a coating with at least one acid. After applying ink and applying the liquid, a water-containing further liquid is applied both to image regions and to non-image regions of the printing material. The first-mentioned liquid and/or the further liquid contains at least one substance for at least partly neutralizing the acid. The undesired formation of crease waves or curls and glossiness fluctuations between varnished image areas and varnished non-image areas is thus advantageously avoided.
