yes. saving a screenshot as JPG (lossy format) adds more loss - if you started with a lossy image in the first place then we are losing even more information by screenshotting it and saving it again in a lossy format. even when not intended for print, when making formal documents and presentations I look for the original images at highest resolution available.
