Paper testing in one form or another is undoubtedly as old as papermaking itself. Perhaps it is not too fanciful to assume that the ancient Egyptian scribe examined his sheets of papyrus to ascertain whether they would be suitable for his inscription; of the proper texture, thickness and over-all appearance. He can be visualized as holding a sheet up to the light to determine its formation, as feeling it between thumb and fingers to gage its smoothness and bulk, and possibly even tearing a corner to see whether it had proper strength. It is certain that, unless human nature has changed over the centuries, he complained at times to his supplier that the sheet was not suitably ink receptive—that it was improperly sized.
