Join Taz Tally for an in-depth discussion in this video Scanning a printed image, part of SilverFast: Scanning.
In this video, I'd like to address a very specific kind of scan, and that is…scanning an image that's already been printed on a printing press or a laser…printer or something like that.…The difference between a printed image and a photograph is that the photograph…is pretty much continuous tone, that is you can't see the structure in the image.…Whereas a printed image has an actual pattern of halftone dots.…I've already done a prescan here just to kind of move the process along a…little bit and you'll notice, if you look in the background, you can see the…pattern. That pattern is the pattern of halftone dots that has been captured by the scanner.…
In this particular video, our primary issue is going to be descreening and that…is taking out the screen pattern that results from scanning a halftone image.…If you don't take out this pattern and you reprint this, it looks much worse…than this, because reprinting an image that hasn't been descreened creates all…sorts of imaging nightmares called moire patterns, which can be two or three…
