Abstract: A system to determine a relative position between a moveable part and a working surface is disclosed. The system comprises a controller to control a light emitter from an array of light emitters to emit a signal at a setting, the setting being indicative of a position associated with the light emitter. The controller further to receive a signal from the sensor indicative of the setting. The controller also to determine the relative position between a moveable part and the working surface based on the signal.

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.
