The specific way this works in the Pro-1000 is as follows. Applies only to gloss, semi gloss, luster media. You may either clear coat the entire page including margins, or only to areas that have some level of contrast the printer can detect. In this case white and near white areas are not coated. You select the option in Print Studio Pro. It is not meant primarily for dealing with gloss differential though it contributes to mitigating it if you coat the whole page. The main intent is to optimize chroma as the name implies.
