COMP Cams Camshaft A8 299THR7 ThumperDesigned to deliver an aggressive, hard hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve.

I’m a bit new to sublimation and was worried about having dull colors, but this ink is doing wonders! The quality is great, I can adjust the amount on the printer and get the exact, rich, vibrant colors I want. (I found some recommended settings for brightness, contrast, etc… and then tweak the cyan, magenta, and yellow to the desired amount.) I definitely recommend getting this ink! It’s so easy to refill the printer (I have an Eco tank 15000). The cost is not bad at all. I’ve only washed some of the items one time and so far the ink has remained unchanged. Seems like a winner to me!

Vibrant colors, great traction on fabric, and easy cleanup

This sublimation ink has been a great find. The colors are vibrant and transfer beautifully to fabrics, mugs, and phone cases. The traction on the material is excellent—designs don’t smudge or fade easily after pressing. I also appreciate how clean it is to work with. Refilling my Epson EcoTank printer was simple, and there were no messy drips or stains. Cleanup of tools and surfaces was quick with just a damp cloth. For beginners or experienced crafters, this ink delivers consistent, professional-looking results every time.
