Digital BW, The Print

One other note.  The images on the best of these papers could be framed
without spraying...but the surfaces are delicate...so you would need to
mount/frame to prevent people from handling them.  A light coat of Krylon
solves this problem...but if you want to preserve the true gross surface of
papers like the Spectra Jet of the Brightcube Gloss or Epson Premium Matte
you will need to not spray.
