Coloring Rubber Cement

[tkamiya]

I am using rubber cement to partially cover my print (FB Matte) so that when I tone it won't affect the area with the cement.

A big problem is that some of my rubber cementing is very intricate and the material being basically milky clear and when dried clear, it's hard to spot a thin area or area that didn't get covered. I'd like to color the rubber cement but with a material that won't color the paper that is being applied to. I'm using brush and toothpick to do this and a magnifier but I'm still missing spots.

Can anyone think of a coloring material that would do it? I'm thinking any kind of dye wouldn't work but fine colored powder that is NOT soluble might. Problem is, I don't know what that might be.

Help!

Carbon black ought to work.

I have a question.

WHAT'S THAT? A powder? Is it available in art store?

Why not save yourself some headaches and just use Friskit?

There used to be a product called Maskoid that was ruby red which was perfect, but like many obscure analogue photo aids, it is sadly long gone.

Re: Frisket,

I can. In fact, I'll look for that brand. What I found was not colored, so I just used rubber cement.

M. Lointain:

Can you give me a product spec of some kind? I found products called Art Maskoid and Photo Maskoid but they are gray. I'd prefer red.

Found it! Photo Maskoid is actually red.... Yay. Ordering one.
Thanks.

That looks like the stuff but I hope they still have it. The page is dated 2005.

I know... I emailed the owner. Will see if he responds.

If I have understood the literature correctly Fotospeed Fotomask is red. Is this particular Fotospeed product not available in the U.S.?

Last I looked they have it at Freestyle.

I see it.

I called around and found something similar at a local art supply store. Expensive little can.... I'm going to go there in about an hour and try this one out later.

Fotomask is red but loses its colour over time. This doesn't appear to alter its efficacy in any way but it does make it harder to see where you're applying it. It should also be used with the brush cleaner fluid. Both of them stink like f**k so use good ventilation.

I found a product called "Art Mask". It's a lightly yellow tinted latex based frisket. It's little easier to see compared to rubber cement but it's still pretty hard to see unless applied very thickly. It also is very watery and hard to apply. One quality I did like is that it doesn't have the offensive and toxic fume that rubber cement has. It has some slight ammonia smell but not bad.

I got the job done well enough so I'm pretty happy. I'm becoming a known face at a local art supply store.... I'm there every weekend!
