While the RL3996IW labels were designed to work well on Primera printers primarily, they are fit on a 3" core with an outer diameter of 6", which looks to be compatible with the PLS-475i. The White Weatherproof Gloss Inkjet (IW) labels feature a topcoat that is designed to encapsulate and protect the ink as it's absorbed into the label. After printing, the ink shouldn't smear when touched with a wet hand or when soaked in water. However, oil or alcohol-based products may impede the quality.
