<p>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, the method comprising the steps of assigning a printing element to each pixel of a part of the image, said part consisting of a plurality of rows of the image, and upon detection of a defective printing element among the assigned printing elements, increasing the number of pixels in each row of the part of the image by x pixels, each pixel having a value zero, resulting in the part of the image comprising m by n + x pixels, assigning a printing element to each pixel added to the part of the image in step b), identifying pixels to which a compensating printing element of the defective printing element is assigned and which have a value zero, changing the value of at least one identified pixel into an integer value greater than zero, 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 printing the 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 the part of the image. The invention also discloses a printer configured to carry out the method. Also a computer program is disclosed for enabling the printer to carry out the method.</p> |
