wherein the retention body comprises, on the first side, a first receiving portion facing the inner region and, on the further side, a second receiving portion facing the inner region; wherein the retention apparatus is embodied to retain at least one optical module, which has a light input side and an opposing light output side, by means of the first receiving portion, the second receiving portion, and the at least one spring element in a retention state,
in such a way that the at least one optical module in the retention state is retained a. in a first direction extending from the light input side to the light output side by means of an interlock of i. the at least one optical module with the first receiving portion and ii. the at least one optical module with the second receiving portion, and b. in the opposite direction to the first direction by means of a spring force of the at least one spring element directed against the at least one optical module.

Further, the invention relates to a luminaire having the retention apparatus according to the invention; a printing machine having the luminaire according to the invention; a production method using the luminaire according to the invention; and uses of the retention apparatus according to the invention; and of the luminaire.

A method is provided for printing a surface of a non-absorbent substrate with an ink to be applied by an inkjet printing device. An ink that contains water as a solvent is used for printing the substrate. An ink having a water content of at least 70% is used. The substrate to be printed is supported by a workpiece support and is moved relative to the inkjet printing device. During this relative movement, ink is applied by the inkjet printing device to the surface of the substrate to be printed. The ink that is applied to the surface of the substrate is heated to a temperature that is above the temperature of the air surrounding the substrate and that is below the boiling point of the solvent contained in the ink. Above a liquid phase of the ink, a vapor layer, consisting of the solvent that is contained in the ink, is formed. The vapor layer that is formed above the liquid phase of the ink is transported away by an air flow emitted by at least one blower nozzle unit. The air output by the respective blower nozzle unit is heated or is dehumidified beforehand. A digital printing press is provided for carrying out this method.

There is provided a printing apparatus including: a transport section that transports a medium in a first direction; a printing section that makes a liquid adhere to the medium transported by the transport section; a heating section provided downstream of the printing section in the first direction, in which the heating section includes a first heater that extends to a first range in a second direction intersecting the first direction and a second range positioned on one side in the second direction from the first range and heats the medium, and a second heater that extends to the first range and a third range positioned on the other side in the second direction from the first range, and heats the medium, and heats the medium by the first heater and the second heater when the printing section made the liquid adhere to the first range on the medium.

Provided are: a photocurable ink composition including particles of a squarylium coloring agent represented by Formula (1) a radically polymerizable monomer, a radical polymerization initiator, and a coloring agent sensitizer, in which a volume average particle diameter of the particles of the squarylium coloring agent is 10 nm to 400 nm (in Formula (1), ring A and ring B: an aromatic ring or a heteroaromatic ring; X.sup.A, X.sup.B, G.sup.A, and G.sup.B: monovalent substituent; kA=integer of 0 to nA; kB=integer of 0 to nB; nA: an integer that is a maximum number of G.sup.A the ring A can have as its substituent; and nB: an integer that is a maximum number of G.sup.B the ring B can have as its substituent); and an image recording method.

Disclosed is a carriage for a direct to garment inkjet printing machine. The machine has a frame having a leading edge, a trailing edge, and a pair of opposed lateral edges. A first row of slots is positioned on the leading edge and a second row of slots is positioned on the trailing edge. The second row of slots is spaced from the first row of slots by a gelling gap. A shelf on the frame supports tanks of white ink and tanks of color ink and a first plurality of tubing connects a tank of white ink positioned on the shelf with a print head in the first row of slots. A second plurality of tubing is for connecting a tank of color ink positioned on the shelf with a print head in the second row of slots. A pair of side heaters attached to opposed lateral edges of the first frame.

There is provided a printing apparatus including: a transport section that transports a medium in a first direction; a discharge section that discharges a liquid to the medium transported by the transport section; and a heater that is provided downstream of the discharge section in the first direction, and heats the medium, in which the heater includes a ceramic substrate, a heat generating resistor provided on the ceramic substrate, and a protection section that protects the heat generating resistor.

A method and equipment to form a digital print by applying dry colourants on a surface of a panel, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colourants on the liquid binder and the surface; bonding a part of the colourants to the surface with the liquid binder; removing non-bonded colourants from the surface such that a digital print is formed by the bonded colourants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colourants are permanently bonded to the surface.
