Abstract: Examples herein provide a method. The method includes preconditioning a printing apparatus, including: increasing a temperature of an inkjet printhead in a print zone in the printing apparatus to a first temperature higher than or equal to about a steady state printhead temperature; and increasing a temperature of the print zone such that a portion of a print medium disposed over a portion of a platen in the print zone is at a second temperature higher than or equal to about a steady state print zone temperature. The method further includes disposing, using the printhead, an ink at the steady state printhead temperature onto the portion of the print medium to form an image thereon.

Abstract: A method and apparatus for processing image data is described. An example of a method involves applying a first mask to image data corresponding to an overlap zone of a first print region, the first mask representing a first mask pattern and applying a second mask to image data corresponding to the overlap zone of a second print region, the second mask representing a second mask pattern. Each of the first and second mask patterns define a periodic variation in a dimension corresponding to the first direction. First and second mask patterns for at least a second image plane are spatially separated in the dimension corresponding to the first direction in relation to first and second patterns of a first image plane.
