Abstract
A novel printing system and associated printing methods that can overcome many of the obstacles presented by today's printing systems. In certain embodiments a printing vehicle is presented that may work in cooperation with other vehicles to produce a system capable of delivering a wide range of productivity and scale. This printing system is amenable to novel printing methods that can reduce printing defects and ink consumption by up to 30%.
Claims10
A method of printing for improved image fidelity, comprising the steps of:
- providing at least one printing unit configured to print at least one print material according to a set of print data;
- providing a printing raster containing raster locations, each raster location associated with a portion of the print data, wherein the printing raster is represented by a hexagonal grid comprising a plurality of pixels, wherein a center of each pixel in the printing raster is equidistant to a center of each neighboring pixel;
- conducting a first printing pass by moving the printing unit relative to a printing substrate in a first printing direction while printing at least one print material according to at least a portion of the print data;
- and
- conducting a second printing pass by moving the printing unit relative to the printing substrate in a second printing direction while printing the at least one print material according to at least a portion of the print data;
- wherein the first printing direction and the second printing direction are disposed at a non-orthogonal differential angle other than 180 degrees;
- and
- wherein the printing raster, the first printing direction and the second printing direction are together selected such that at least 25% of the raster locations defined in the printing raster are capable of being printed by the printing unit during each of the first printing pass and the second printing pass.
