check_logo

Window > Logo Check: tests the logo (ids, or the selection / whole document when omitted) the way it will be used — rasterized at 16–128 px to find thin parts that disappear and gaps that close up (returns the smallest size where every detail holds), and checks its colors: contrast with the background (under 3:1), colors that merge in grayscale, color count, and gradients/patterns/images/transparency that one-color printing loses. Each warning lists the object ids involved.
