Patent ID: 8777353

Claim:
A method of printing an image on a receiving medium by a printer comprising at least one print head with printing elements, each printing element associated with at least one compensating printing element, said image comprising a raster with rows of n pixels and columns of m pixels, each pixel having a value zero or an integer value greater than zero, said rows intended to be printed at a first printer resolution in the main scanning direction, said method comprising the steps of: a) assigning a printing element to each pixel of a part of the image, said part of the image including a plurality of rows of the image, and upon detection of a defective printing element among the assigned printing elements: b) increasing the number of pixels in each row of said part of the image by x pixels, each pixel having a value zero, resulting in said part of the image comprising m by n+x pixels; c) assigning a printing element to each pixel added to said part of the image in step b); d) identifying pixels to which a compensating printing element of the defective printing element is assigned and which have a value zero; e) changing the value of at least one identified pixel into an integer value greater than zero; f) increasing the first printer resolution in the main-scanning direction to a second printer resolution in the main-scanning direction by multiplying the first printer resolution in the main-scanning direction with a factor equal to (n+x)/n; and g) printing said part of the image on the receiving medium according to the second printer resolution in the main-scanning direction and according to the values of the pixels of said part of the image.
