I'm running an Iseries(as400) V5R3 and am getting conversion errors with TIFF2PDF on some tiff's but not all. These tiff's are valid, and display in different viewers, but the pdf is bad when converted. I'm receiving the error message -- Warning, unknown field with tag 32934 (0x80a6) --. Any help would be greatly appreciated.
