Hey guys I just tested out a bunch of options and I thought I would share my experience.
NOTE: I would upload images, but the form won't allow me.
So I tested different shirts, some pure white, off white, and heather options. Below are the 4 options that I tested, and my thoughts on the results.
1. Pure bucket white - Surprisingly it lays down pretty well since bucket white is pretty thick. This worked way better than I thought being water base. Showed up great on a pure white tee, no problem.
2. Pearl flake with a touch of black - looked great but turned out just a little to grey. Depending on the look and how you mix, it's a great option that gives you just enough contrast. Pearl flake is always a great look, the shine gives it a nice contrast.
3. White with a drop of blue - Turned out a bit to blue on me, but if mixed right would be a great option.
4. White with a drop of yellow - This was my top pick to achieve the look I wanted. Much like the blue, you only need the smallest amount of yellow in order to not tint the ink to much. It was a bit more forgiving than mixing the blue however. it gave the white on white the right contrast and in my opinion the best results for me.
Thanks for everyone's tips:)
