Hello All, I want to buy an airbrush for only a single application - edging cards for letterpress. I'm a letterpress printer and I want to add a new service for my business. Essentially, my needs are very simple. Occasional Use - maybe once a week, sometimes only once a month or less Wide, even spray pattern - I won't be doing fine detail, just broad even strokes to cover the sides of the card stacks when they're clamped together. I likely won't need a variety of tips or tons of settings, just even single color coverage. Easy Cleaning - The easier to clean the better. I take good care of my things, but when I have to wash up the printing press and a bunch of stuff, I don't want to have to spend ages cleaning out the airbrush too. Good Coverage - I probably will only spray one color in a use, I might do two color gradients, so I think a gravity cup unit would be good (yes?). I will likely be doing about 200-500 square inches at a time (imagine a stack 10 inches tall of 5x7" cards clamped together). I don't mind re-filling, but if it's going to be every two seconds I'm willing to spend more on something more appropriate. I've seen some cheap units on ebay for about 40 - 60 dollars that come with a gun, compressor, and paints (just go to ebay and search airbrush, you'll see.. it won't let me post links here) Would these work? I'm really not planning on doing anything complicated with it and don't want to over invest in something really fancy. Any advice would be really helpful, I'm a designer and have used all manner of tools, inks, and processes (from welding to glass), but I've never used a airbrush before! P.S. Regarding ink... what is a good ink for paper? Would Golden Acrylics thinned with a little water be fine? (I know they have a high flow airbrush line).
