Tiff is the standard for records management archivists. It has been around 10 years longer than PNG which was a patentless replacement for Gif (Unisys). It is also lossless. Adobe has copyright on specifications for Tiff. Carries a bit more metadata than png. It is a lot clearer displaying straight lines.
