Abstract: A printing apparatus is disclosed herein. The apparatus comprises a platform defining a printing zone to hold a media moveable along a media path direction; a first sensor at a first location along the media path direction to measure a media advance at the first location; a second sensor located at a second location along the media path direction downstream the first location, the second sensor to measure the media advance at the second location; and a controller. The controller to determine a deformation gradient of the media based on a first set of measurements of the media advance by the sensors at the first and second locations and adjust an image to be printed based on the deformation gradient.

Abstract: An apparatus is disclosed herein. The apparatus comprises a carriage to move laterally in a scanning direction over a platen, a scan beam to support the carriage over the platen, a mechanism to move the scan beam vertically, and a media holder. The media holder comprises a central portion to hold a media on the platen, a first end couplable to the platen at a coupling position, and a second end couplable to the scan beam such that the second end moves vertically along with the scan beam.
