Abstract
According to one example of the present invention there is provided a method of printing, with a printer, an image on a substrate, the printer comprising a substrate support. The method comprises obtaining an image to be printed, determining an offset position of a substrate positioned on the substrate support relative to a predetermined reference printing position, and controlling the printer to print the image to be printed at the determined offset position.
Claims20
A method of printing, with a printer, an image on a substrate, the printer comprising a substrate support, the method comprising:
- obtaining an image to be printed;
- producing an image of at least a portion of the substrate support;
- determining, using image data for elements of the substrate support from the image of the at least a portion of the substrate support, an amount of skew of the substrate relative to the substrate support;
- based on the determined amount of skew, determining an amount of rotation of the image to be printed;
- and
- controlling the printer to print the rotated image.
A printer comprising:
- a substrate support:
- an imaging module to obtain image data of the printer substrate support;
- a printer controller to:
- obtain an image to be printed;
- determine, based on the image data obtained from the imaging module, the position of a substrate relative to a predetermined reference printing position on a substrate support and an amount of skew of the substrate relative to the substrate support;
- determine an amount of rotation for the image to compensate for the amount of skew to generate a rotated image;
- and
- control a writing mechanism to print the rotated image on the substrate such that at least some of the edges of the printed image are substantially parallel with at least some of the edges of the substrate.
A method of printing, with a printer, an image on a substrate, the printer comprising a substrate support, the method comprising:
- obtaining an image to be printed;
- producing an image of a portion of the substrate support, the portion of the substrate support including a grid of alignment features disposed on the substrate support and the substrate;
- determining, by visually identifying in the image of the portion of the substrate support, image data elements of the grid on the substrate support, the position of a substrate when positioned on the substrate support and an amount of skew of the substrate relative to the substrate support;
- rotating the image to be printed based on the determined amount of skew to produce a rotated image;
- and
- controlling the printer to print the rotated image on the substrate, such that at least some of the edges of the printed image are aligned substantially parallel to at least some of the edges of the substrate.
