I had a bit of a flash back the other day...
I once had a shop at the Piece Hall in Halifax. We made canvas prints and framed them gallery wrap style to order. One of our customers was a lady who did oil painting commissions. She woould call in with an image on a USB and would want us to print it on canvas, but not as dense as a normal print - a kind of faded version. She would then use that image as a guide for her oil painting skills.
They must have worked as she was always placing orders!
This got me thinking. All printers like to be used, otherwise the inkjet nozzles clog up, and I'm not always using it for my own artworks, so I did a little research, and although there is a little debate around the subject, I thought maybe I would make a web-site and promote them in the hope of filling a little gap both in the market and in my situation here.
At first I feared that the pigment inks would smudge, but I got some linseed oil, some water, some Damar retouching varnish, some B&Q gloss varnish!! and I rubbed and rubbed, and no I don't think the pigments are likely to leach into the oils or acrylics.
Footnote: This is yet another abandoned project
