Interested in experimenting with photo transfers on canvas- using acrylic paint & glass gel medium as well as caulking. I know I need to use photo copies or laser jet images, but are there certain types of images that are better than others? should i use something that's very liney as opposed to something with more detail? black & white better than color?

i'll probably try both anyway, but curious about others' experiences.

Thanks-

By transfer I not sure what you mean.  If you want to transfer the printed copy, that is the paper on which the image is printed, use acrylic medium as the 'glue.'  You can also transfer the image onto the canvas - printed 180-degrees opposite to what you want to see on the canvas.  Regular bond paper works ok and the intensity of the transfer will depend on how good is the printed image.  You let the acrylic medium/transfer dry completely and then wash off the paper backing.  Keep wetting and rubbing off the paper - I've even used a hose pipe. 

If you decide to use photographic paper for a more detailed image, use only matte finish paper.  Gloss finish paper will leave the image as a layer not embedded in the canvas and can be peeled off like acrylic paint can be peeled off.  Experiment.

Above is a detailed article on transfers.

i have tried caulk & acrylic medium- the caulk method from a photocopy worked best for me. also, if you plan to paint over the transfer & want to maintain it;s integrity, i'd suggest a few layers of srpay varnish- i ended up drawing part of one back in with mechanical pen.

have fun!
