Thermography ... any hints?

[Roadracer_Al]

Having spent my entire professional life tangental to the printing industry, I thought I could add something... in that context, thermography is a post-print process in which powdered plastic is dusted onto the still-tacky ink, the excess blown off & recycled, then run through a heat setting oven to give the type a raised, slightly pebbly finish. It was very popular in the '80s on business cards.

Sorry, no 1" steel tanks involved. :)
