I have mentioned gum
arabic transfer in previous posts, it is a technique I use a great deal to start off sketch book pages and allows me to place a photographic element into my compositions.

For some time I have been aware that it is possible to use gum
arabic transfer as a colour separation print. So with this image as a starting point I had a play.
First take your colour original and using photoshop produce a set of colour separations, yellow, magenta, cyan and black. My long suffering computer whizz of a friend Jane did this for me, for which I really thank her. These 4 copies must be in a contrasting black and white and printed using a toner copier...not ink jet. Have them photocopied. Cut your images so that you have a registration corner where they will all match, mine is bottom left which will turn into bottom right when I print.

Set up your colours, I am using oil based
etching ink from Intaglio
Printmakers in Magenta, Process Yellow, Cyan Blue and Black. Add a small amount of linseed oil to the ink to slacken it off.

Lay your yellow copy on a piece of baking parchment and cover the back then the front liberally with gum
arabic. I get mine from Hawthorn Inks.

Place copy image side up on a magazine as it will stick to newspaper and you can reuse the parchment to gum another copy. Roll the ink in thin layers all over the copy.

Take inked copy to the sink, I always place it on a piece of perspex at this point and spray with a plant spray bottle until most of the ink has shed off the white areas. The water will
dissolve the gum
arabic taking the ink with it and the greasey toner marks will hang on to the ink.

I ink all my copies before I print, leaving them to drain on blotting paper

You are now ready to print. Place the yellow copy down first, I use
Snowdon Cartridge paper, 300
gms, anything thinner makes the
receiving surface buckle with the
wetness.

Place a sheet of blotting paper on top and rub with a wooden spoon. Repeat this process with the red, blue and
lastly the black copies matching your registration corners.

The ink releases onto the paper. I quite like the inaccuracy of the registration.

If I had wanted the look of the original image I
would have just printed it out. I intend to try a print using a different set of reds, yellows and blues. Have some fun with it, experimenting is very rewarding.
This post would not have been possible without the technical support of my friend Jane and the photographic skills of my son Toby.
Thankyou to you both.
