Are paperboards dimensionally unstable ?

Does a glossy board surface ensures glossy print ?

Though a glossy boards surface helps to give a glossy print but it does not ensure a glossy print. More than the glossy surface the ink hold out of a substrate, roughness and the kind of ink used, and the press parameters play important role in print gloss.
