I just bought 3 quarts of custom pantone mixes from MelRay Industries in Crescent City, FL. They use International Coatings inks, which I'd never used before. The quarts ran around $28 average with the custom mixing charge included. I also purchased a quart of plain black which was $21, so I'm guessing the custom mixing charge was about $7.50 each, which is reasonable. I have to say I'm really pleased with the ink. Nice and creamy, excellent opacity, prints like a dream through 305 mesh. These mixes are for a QuikSeps Pro simulated process job I've gotta pound out. I have the Union Mixopake mixing system, but some of the colors come out kind of gummy and tough to pass through the screens (might be the fact that they're high opacity inks).
Anyway, just thought I'd pass it along. They also sell Matsui inks and screens, plus other supplies. Very nice people to work with. I plan on rounding out the specified pantone colors for QuikSeps Pro with the IC inks fro MelRay.
