We just did a glitter print last week. You can get the glitter from
http://www.jantexinks.com/specialties.htmWe put a ton into a slightly tinted shape base through a 40, and it came out sweet.
We under based it white, then the pink we wanted, then the tinted base with glitter. Came out rad.
If you add enough glitter to white, it may work, but I would be looking to do it with clear.
On this job, we tried crystallina, and we didn't get the effect we were wanting.
Hope it helps!
