RE: Making carbon tissue

Sandy, do you have a thickness preference or you choose the degree of relief
according to the image? I'm asking that because I never saw a carbon print
before and I don't have any idea about what does relief add too (or detract
from) the image...

TIA,
Loris.

Issues regarding thickness of carbon tissue are the following.

Thin, heavily pigmented tissue gives maximum printing speed but very little
relief. By thin I mean wet tissue height of .5mm or less.

Thick, lightly pigmented tissues gives maximum relief but printing times are
very long, 2X-4X more than thin tissue. By thick I mean a wet height of
1.0mm or more.
