20100033545 | Ink Jet Printer and a Process of Ink Jet Printing - 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. | 02-11-2010 |
20100285282 | Ink Jet Ink and a Method of Ink Jet Printing - The invention describes a radiation-curable ink jet ink, which comprises at least 50% by weight of cyclic trimethyllolpropane formal acrylate (CTFA), and further comprises a free-radical photoinitiator, and which is substantially free of volatile compounds. | 11-11-2010 |
20100321445 | INK JET PRINTER AND AN INK JET PRINTING PROCESS - 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 vapour 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. | 12-23-2010 |
20110000878 | INK JET-PRINTABLE COMPOSITION AND A MASKING PROCESS - A radiation-curable, ink jet-printable composition comprising a compound having a reactive silyl group that is suitable for use as a masking composition and/or processes in which the composition is applied onto a substrate; the printed composition is exposed to radiation to form a cured image that masks selected areas of the substrate; the unmasked areas of the substrate are modified; and the cured image is treated with an alkaline solution in order to release the cured image from the substrate. | 01-06-2011 |
20110008547 | JET INK AND INK JET PRINTING PROCESS - An ink jet-printable composition, which comprises a compound having a reactive silyl group and which is suitable for printing on non-porous substrates such as a glass or ceramic, and a process of decorating non-porous substrates involving ink jet printing the composition onto the substrate, exposing the printed composition to actinic or electron beam radiation to initiate curing and heating the printed composition to a temperature of at least 100° C. | 01-13-2011 |
20130235140 | INK JET PRINTER AND AN INK JET PRINTING PROCESS - 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 vapour 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. | 09-12-2013 |
