Abstract
A skewed substrate pixel array printing machine includes a frame; a printhead mounted to the frame for printing pixels onto a platen; a device for providing relative motion between the printhead and a platen; and a platen for printing thereon. The platen has a platen axis parallel to a direction of the relative motion between the printhead and the platen; and a rectangular area thereon for printing onto. The rectangular area importantly has an edge thereto that forms an image defect preventing first skew angle with the platen axis.
Claims10
A printing machine comprising:
- (a) a frame;
- (b) a printhead mounted to said frame for printing pixels onto a platen;
- (c) means for providing relative motion between said printhead and a platen;
- and
- (d) a platen for printing thereon, said platen having;
- (i) a platen axis parallel to a direction of said relative motion between said printhead and said platen;
- and
- (ii) a rectangular area thereon for printing thereon, said rectangular area having an edge thereto forming an image defect preventing first skew angle with said platen axis, wherein said platen is a rotatable drum member and said rectangular area comprises a substrate supporting area for supporting a rectangular substrate in registration with said rectangular area, and a value for said image defect preventing first skew angle depends on a diameter of said rotatable drum member, on a size of said printhead, and on a number of passes of said rotatable drum member for printing a complete swath.
