Halo artifacts
i'm converting grey-scale tif files of scanned sheet music pdf acrobat 9 pro , having trouble halos of grey pixels appear around in pdf. weren't there in tif. can't see them when print document, i'm wondering if these artifacts increasing file-size of pdf. plus annoy me. there way rid of these, other using "optimize scanned pdf" after conversion has been done? this typical of jpeg compression. aren't there, jpeg bit random @ edges , halos can appear. see if there options save tiff zip pdf rather jpeg - jpeg poor scanned text , lines.
