Does anybody have a good way of mixing colors before adding to plastisol? For example, if I want a particular shade of green.... is there a way to test the outcome of a blend of pigments before adding to the heated plastic and commiting to the pour?

There was a post on this a while back saying that if you used mineral oil, it would give you a similar color to adding it to plastic. I personally haven't tried it so I can't say how it would work.

I would use softener / worm oil vs. mineral oil. Mineral Oil can cause problems down the road with your plastic.

Oh I thought he meant to see what colors would look like,but if the colorant/oil in the plastic after softener or worm oil would work perfectly.

Yeah I was trying to figure a way to formulate a color and tweak it before adding to the plastisol. Sounds like there are a couple of options there. Ill look into it, but as of yet, I don't have any of those products...yet.
I saw the videos Jason. Very informative.

When to add colorant is a pretty flexible rule. Bright colors like the flourescents are probably best added pre-cooking, though I've added after cooking with no problems. I'll add what I think will be enough, a little on the conservative side if need be, before heating. After heating I shoot a bait and see how it looks. Single cavity molds are great for this, you only have 1 off color bait if the color isn't right! Adding colorant to hot plastic works well enough for adjusting the color. I'll also do something similar if I want to shoot 2 shades of the same color. Sometimes I might want to make a batch of light blue baits and a batch of dark blue. I'll start with light blue, shoot my baits, and then add more colorant and shoot the dark batch.
