              Do you think this makes the material porous in the same way as
paper is porous?

              So these holes act as a key to some kinds of coating? Maybe
P.V.A.?

               They were obviously looking for something that would hold
more firmly onto the pigment ink. Pete's Fotempera process and other Direct
Carbon processes, such as gum, and the Fredricktype process seem to work by the
unhardened pigmented colloid being able to release cleanly from the sized
support. Would this Melinex lend this attribute to these processes?

                   Its a project for testing. Thats for sure.
