The top of every page is perfect. The more pages you print on this special paper (not much thicker than 80 weight.) the worse the effect is. However printing on plain paper with full page picture will not produce the same effect. The best I can describe is like how a paint roller runs out of paint and leaves only partial coverage. Waiting for the company who makes the paper to get us exact specs on the paper. Any help is appreciated. The application is cloud based and creates a PDF before actually printing. The problem does not happen on the other color printer available.
