Contact: Mark Schwerin

KALAMAZOO—A longtime veteran with more than 50 years experience in the paper industry and a leading figure in paper technology research will lead an in-demand workshop on paper coating in late July at Western Michigan University.

Charles P. Klass, president of Klass Associates Inc. in Madeira Beach, Fla., and Dr. Margaret Joyce, WMU professor of chemical and paper engineering, will present "Principles and Practices of Paper Coating" July 29-31 at WMU. The course is designed for the newcomer to the paper coating industry as well as those with some experience who wish to broaden their knowledge and understanding of paper coating materials and processes.

Charles P. Klass

Klass graduated from WMU with a bachelor's degree in pulp and paper technology and earned a Master of Business Administration from Pace University. His long tenure in the paper industry includes technical and operating positions with Hamilton Paper, Oxford Paper, Union Camp and Westvaco, editorial experience with Paper Trade Journal, and technical service, sales and marketing management positions with Merck Chemical, Lockport Felt, Asten Group and Inventing/BTG Coating Systems.

In 1986, he became a consultant to the paper industry specializing in coating, surface sizing and development of value-added papers. He is a frequent guest lecturer at universities nationwide and has been active in TAPPI and has served as chairman of the Paper Board Manufacturing Division, the Coating Process Committee and on the TAPPI Board of Directors. He has numerous publications to his credit and is a featured speaker at many paper industry conferences, seminars and short courses.

Klass has seven patents on papermaking and paper coating, and his research interests include development of recyclable barrier coatings, digital printing papers, high graphic quality containerboard and lighter-weight, paper-based packaging.

Dr. Margaret Joyce

Joyce has been a member of the WMU faculty since 1996, having received chemical engineering and wood and paper science bachelor's degrees, a textile and polymer chemistry master's degree and a wood and paper science doctoral degree, all from North Carolina State University. Prior to joining the faculty, she was employed at SYN-CHEM Inc. as technical service manager and director of research from 1985-96. During her tenure in the private sector and as a faculty member, she is acknowledged to have made a significant contribution to the paper industry as a research scientist and demonstrated creative talents, particularly in the coating and printing areas.

Joyce has both presented and published her research extensively for the benefit of academia and paper and printing industries, demonstrating both her creativity and tremendous productivity in both the printing and paper industries, contributing to analytical technique, formulation, methodology, equipment design and configuration and new product design. Her work in the areas of nanotechnology, high-speed curtain coaters and radio frequency identification, or RFID, are considered at the leading edge of development. She is a member of a long list of professional societies within the industry, including the Technical Association of the Pulp and Paper Industry, or TAPPI, Phi Lambda Upsilon, the American Chemical Society, Society of Rheology and International Association of Packaging, as well as a reviewer for the International Journal of Solids and Structures.

Course information

Joyce and Klass, both TAPPI fellows, will cover topics including coating methods; coating drying methods; gloss development methods; coating raw materials; on-line measurement and control; and coating preparation, handling and testing. Klass will begin his presentation with an overview of coated printing and imaging grades and current market trends.
