How many colors can be used on my DrumART custom bass drumhead?

Eleventy billion.

Okay, maybe not eleventy billion. But literally millions. Our printers output at 1440 DPI using six-color (CMYK + light cyan + light magenta), eight-color (adding orange and green) or twelve-color (CMYK + RGB, matte black, gray, matte gray, photo cyan, photo magenta) processes — chosen based on what your artwork needs, not on what our equipment is limited to.

In English: you can have whatever you want printed on your head and it will look spectacular. Vector art, high-resolution photography, subtle gradients, deep blacks — all of it.

And don't be fooled by anyone telling you the benefits of more colors or higher resolution are a myth. They're covering for their own hardware. More ink and more colors means richer prints, deeper colors, finer gradients, and sharper lines and edges.
