dubplate
n.— «The real money is not in album sales but in live shows, and in dubplates: customized versions of singles, each one personalized with a salute to the D.J. who commissioned it. He often charges $500 to $1,500 for dubplates (though some important D.J.‘s get them cheaply or even free), and he might record more than a hundred dubplates of a big hit.» —“A Reggae Star Forged in the Dancehall Furnace” by Kelefa Sanneh New York Times Mar. 9, 2006.
