The Blissful Dog Nose Butter™, handcrafted from organic good stuff, is shea butter (and more rich goodies), so the label needs to be somewhat oil resistant. Plus, I use all photos of dogs on the label,s the photographic repro needs to be great. I have over 50 different breed labels for sale in five sizes of tins alone, so I use a LOT of labels.
I fluff the pages and make sure they are not stuck together before printing. That is about it. The labels work great without much tinkering.
