Abstract
A method of printing an image using a printing system having first and second printheads supplied with a same ink. The method includes the steps of: allocating first lines of the image to the first printhead; allocating second lines of the image to the second printhead; dithering the first lines of the image using a selected first dither mask; dithering the second lines of the image using a selected second dither mask; printing the dithered first lines of the image using the first printhead; and printing the dithered second lines of the image using the second printhead. The first and second dither masks are selected based on a relative alignment of the first and second printheads.

- allocating first lines of the image to the first printhead;
- allocating second lines of the image to the second printhead;
- dithering the first lines of the image using a selected first dither mask;
- dithering the second lines of the image using a selected second dither mask;
- printing the dithered first lines of the image using the first printhead;
- and
- printing the dithered second lines of the image using the second printhead,
- wherein the first and second dither masks are selected based on a relative alignment of the first and second printheads.
