An inkjet printer assembly for printing an image on a recording medium comprises a medium support surface for supporting a recording medium; an inkjet print head for ejecting droplets of an UV-curable ink on the recording medium, the inkjet print head being arranged over the medium support surface; an UV radiation source for irradiating the droplets of UV-curable ink on the recording medium, the UV radiation source being arranged over the medium support surface; a covering arranged over the medium support surface, the covering and the medium support surface together enclosing a print space including the inkjet print head and the UV radiation source; and exhaust means, the exhaust means being configured to vent the print space. The covering comprises a window part arranged such to allow a view on the medium support surface, the window part being at least partially transparent for visible light and configured to filter UV radiation from the UV radiation source to an extent that no harmful amount of UV radiation passes through. Thus, an operator is enabled to view a print result directly as it is printed without being subjected to harmful radiation.

Inkjet printer assembly using a gelling UV curable ink

A method for ink jet printing with light-curing ink, which includes the steps of printing a first ink dot of a color, irradiating the first ink dot with light, printing a second ink dot with the same color and which at least partially overlaps with the first ink dot, and irradiating the second ink dot with light.

Method and printer for ink jet printing

A meltable ink which is solid at room temperature, which ink is suitable for use in an indirect printing process, in which printing process the ink is transferred, by the use of an inkjet printhead, to a transfer element, whereafter the ink is transferred to a receiving material under pressure from the transfer element, the ink having a composition such that it is pressure-transferable at a temperature between a bottom temperature limit and a top temperature limit, wherein the ink has a deformation energy of less than 20&#xd7;10Pa.s at a temperature equal to said top temperature limit.

Meltable ink for an inkjet printer and a method of selecting such an ink

A method of printing a receiving material with hot melt ink using an intermediate element having a surface containing an elastomer with a surface tension in which the polar part thereof is less than or equal to 20 mN/m, wherein the receiving material is brought into contact with the intermediate element in such manner that the ink transfers from the intermediate element to the receiving material, and wherein the elastomer has a hardness of less than 80 Shore A, a thermal conductivity coefficient greater than 0.15 W/mK, and in absorption of less than 10%, and a tan&#x3b4; of less than 0.3.
