Labeling with a No-Label Look

According to Sargeant, a lustre-type PET substrate is typically used when higher print quality or durability is required. "Lustre is a generic term that quantifies the gloss between about 25 GU to about 50 GU. (GU=gloss units, a standard measurement of reflected dispersed light). Again the goal is to match the surface gloss and color of the substrate so that the marking is seen but not the carrier film."
