Sheetfed scanners are prone to moiré patterns when scanning halftones at lower res. A flatbed scanner does better if you are using lower res and have halftone material.

If I had kept the original, I'd go the distance and send in flatbed scans. But I didn't know I'd be doing this post or test. I just happened upon the scans and the 300dpi was supposed to be trashed. I don't keep many things nowadays after they are scanned. Either that are resold on eBay if valuable or trashed, which happens to most of the material. In 2022 I downsized the storage lockers and decided to go all digital. At least that is my goal. I always liked to keep everything, but rent is just too high nowadays. If you are going to dispose of material, always get whatever you need from it as you can't go back!
