I don't believe it's really resampling, which is a specific operation...I just think it takes data and derives at the dither pattern without any resampling. > This is all that is necessary for recognizing Epson resampling > artifacts: > > (1) Create a 180PPI square image (gray, RGB) with almost vertical and > horizontal solid 1 pixel black on white lines. I have had this discussion before...and using lines to test this isn't really a valid test IMO. Yes it shows "something", but what it shows is only valid for lines, not for real photographic images. > Lastly I'll grant you ... this is NOT a "photographic" image, and it is > doubtful you or I would ever be able to point to a resampling > artifact in an > actual printed photographic image ...
