Welcome to our Learning Center

At NPA we strive to be the industry's leader in providing current and useful information to help our clients. The information found in our Learning Center is available to all in our industry wanting to further his or her knowledge of paper, printing, and problem solving.

Over 38 years of Nancy Plowman's experience in paper, coating formulation and in printing had been captured in this series of "Technical Notes". These cover as wide variety of printing issues that we have all had to deal with at one time or another. Most of the information in these documents is actual documented printing problems analyzed in our laboratory.

We encourage our peers in the industry to share this information with their colleagues! If you are experiencing a press issue that is not covered in these notes, please feel free to contact us!
