The backend isn't responsible for any artefacts, it handles the scanned
data 1:1 to the saved image colour file. The Pixma backend only
manipulates the images for grayscale and lineart (1 bit b/w) output formats.
OK, there is some loss with image compression algorithms. If you have
trouble with this, you should select lossless image formats.
Maybe you should test different scan resolutions.
Hope this helps.
