Digital BW, The Print

I only glanced briefly at the site, but the wisdom of paying for such
a service aside, it really highlihts the issue of personal
responsibility and integrity of the artist. Today, digital makes it so
much easier to produce multiples and reproductions in virtually
unlimited quantities of identical quality. If you choose to edition
your work in limited quantities (like I do) you obviously need to
assure a buyer that you will honor the terms under which you are
pricing and selling the print. Making your own print
documentation/certification is straightforward and easy to do, IF you
keep organized and detailed records of your output. Keeping these
detailed records can also help avoid the insurace claim nightmares
mentioned on that site.
At the end of the day, the buyer is depending on your  (or your
representative's) reputation for integrity. As a buyer, if I didn't
trust a particular artist, it wouldn't matter to me what
"certification" they offered. By contrast, I've found that when
selling my work directly, a little personal contact with the buyer
goes a long way. The web is a fantastic tool for showing your work,
but when it comes to purchases of art, I make a point to speak, via
phone or in person with the buyer. In these conversations I give as
much information about the work as possible, offer general guidance on
handling and display, and explain that there will be signed
documentation with each print. I've never yet had a buyer ask about
how I will ensure the integrity of the edition, and I take that as a
sign that they are confident in my integrity.
