There are numerous articles and videos about using Mason Stains as ink for photo-lithography but, while they all say to use linseed oil, I get conflicting information. The same with using gum arabic. There are several types of linseed oil (raw, refined, stand, etc.) and it seems like they have either recommended a particular type (all different) or just said "linseed oil". Some say to use gum arabic and others don't mention it. Any clarification would be appreciated. And, if it makes any difference, I'll be transferring the image onto wet slabs. Thanks, Michele
