Here area few questions that I can answer for those who have asked about making gumoil prints.
What kind of paper?
Make sure the paper you are using is a heavy and quality watercolor paper that can handle multiple passes through this process. I had been using a 310gsm paper but have now found that the 640gsm paper that I have been using, is much better for this process and gives me more flexibility with paints. You can use either hot or cold press, depending on your preference. Some brands I have experimented with success.
Somerset – Stonehenge – Hahnemühle - Arches Platine - Indigo Art Paper ( the 640gsm paper is best for this) and Arches Oil paper.
What brand of oil paint?
This is not easy to answer. I know what has worked for me, but I can’t be sure it will work for you because again, my theory and experience has showed me it is different depending on your water source and atmosphere
Grumbacher pre-tested - Maimeri Classico – Lukas - Old Holland – Schmincke – Williamsburg. It is best to use professional grade paint because the lower grades rarely make you want to try again. I have had trouble removing the paint when using lower grade paint.
What kind of gum Arabic?
That is really up to you. If you know how to mix your own, that is an option. I find that Windsor Newton has a nice premix that works well for me. I have also used Photographers Formulary, which is also a premix.
