Abstract
Methods and apparatus for sublimation printing are described, in which a printed textile medium with a sublimating printing substance on a print side is positioned in correspondence with a heating device, with the print side facing away from the heating device, and a negative pressure is caused on the print side of the textile medium, to cause heated air to flow through the printed textile medium thereby sublimating the sublimating printing substance on the printed textile medium.
Claims15
A method comprising:
- depositing a sublimating printing substance on a print side of a textile medium,
- positioning the textile medium in correspondence with a heating device, with the print side facing away from the heating device,
- causing a negative pressure on the print side of the textile medium, to cause heated air to flow through the textile medium thereby sublimating the deposited sublimating printing substance on the textile medium,
- wherein the sublimating printing substance is deposited on the print side of the textile medium facing away from the heating device before the negative pressure is caused on the print side of the textile medium.
An apparatus for sublimating a printed textile medium, the apparatus comprising:
- a heating device to generate heating energy on a back side of a printed textile medium, and
- a suction device to apply a negative pressure on a print side of the printed textile medium, opposite to the back side, to induce a flow of heated air through the printed textile medium thereby sublimating a sublimating printing substance on the printed textile medium, the sublimating printing substance having been previously deposited on the print side of the printed textile medium before applying the negative pressure, and the print side of the printed textile medium facing away from the heating device.
An apparatus for sublimating a sublimating printing substance on a printed textile medium, the apparatus comprising:
- a support for the printed textile medium,
- a heating device on a first side of the support, and
- a suction device on a second side of the support, to cause heated air to flow through the printed textile medium thereby sublimating a sublimating printing substance on the printed textile medium, the sublimating printing substance having been previously deposited on a print side of the printed textile medium before the heated air is caused to flow through the printed textile medium, and the print side of the printed textile medium facing away from the heating device.
