The invention provides a drop-on-demand ink jet printing apparatus for printing inks comprising water or a volatile solvent onto a continuous web substrate, the printing apparatus comprising: a print head, a chamber for retaining water or solvent vapor in the vicinity of the print head, the chamber having an inlet for the continuous web substrate and an outlet for the printed continuous web substrate, and means for feeding the continuous web substrate through the chamber inlet into the chamber, past the print head and out of the chamber outlet.

Ink jet printer and an ink jet printing process

The invention describes a radiation-curable ink jet ink, which comprises at least 50% by weight of cyclic trimethylolpropane formal acrylate (CTFA), and further comprises a free-radical photoinitiator, and which is substantially free of volatile compounds.

Ink jet ink and a method of ink jet printing

A solid state radiation source array is provided, the array comprising at least one solid state ultraviolet radiation source and at least one solid state infrared radiation source.

Solid state radiation source array

An ink jet printer for printing a cationic ink jet ink is provided. The printer comprises a print head for printing the ink onto a substrate, a heating means for heating the ink on the substrate, and a source of radiation for curing the heated ink.

Ink jet printer and a process of ink jet printing

An ink-jet ink is provided including an ink jet vehicle and a colorant. The vehicle includes at least 35% by weight radiation curable material, based on the total vehicle weight. The vehicle may but does not necessarily include a thickener. The vehicle is a paste or a solid at 20&deg; C. and has a viscosity of less than 25 centipoise between 40&deg; C. and 130&deg; C.
