Abstract
A hot roll glosser and method for the transparentising of resin-coated microencapsulated media includes a pair of heated pressing rolls, in which the roll which comes into contact with a resin surface is formed with an ultra-smooth silicone surface of low furface energy, and the glossing temperature of the rolls at the pressing nip is maintained below the glass transition temperature of the resin. Take-off rolls are disclosed for maintaining a tension in the web material exiting the nip to maintain a negative exit angle with respect to the silicone roll and to prevent adhesion and sticking to the roll.
