Tim:
Though I'm not aware of a specific document, the best source I can think of
for information on the use of recycled-content paper stocks on web presses
would like be the various paper mills. Try contacting S.D. Warren Company's
Information Exchange in Boston, MA.

One factor that would affect performance is the lenght of the paper fiber.
Each time paper is recycled, the fibers are shortened in the process (of
re-pulping), and we know that it is the length of the fibers that impart
strength to the sheet. Because web printing is done under tension (as the web
moves through the press), recycled content could be come a factor depending
upon several other variables such as paper caliper, paper coating, ink tack
(stickiness), etc. A sheet without sufficient strength would suffer frequent
web breakage and would likely be unprintable (by the web process).

I hope this gets you going in the right direction.

Jeff Adrian, The John Roberts Company

Would anyone know of resources that address the technical
aspects/considerations of using recycled (including
post-consumer)content paper in web lithographic presses?
Thank you,
Tim
