Coating symposium positive despite challenges.

The 20th PTS Coating Symposium was held in Munich, Germany, September 18-21, 2001. Almost all U.S. participants cancelled in the wake of September 11; the symposium began with a moment of mourning. Forty papers were presented simultaneously in German and English to over 600 participants representing the industry, institutions and suppliers.

The technical program, directed by Reinhard Sangl and Hubert Runge, covered market changes and needs, and requirements of paper grades. Despite competition with electronic media and the difficult business environment, attendees and presenters are optimistic of growing global demand for coated products. The spectrum and mix of coated paper grades is expected to change accordingly to meet expected worldwide market needs, with the greatest anticipated growth rates of about 6% for woodfree coated grades and commercial printing papers.

The symposium emphasized paper for digital printing processes and non-contact curtain coating as a new option for the application of coating colors. Coating raw materials presentations demonstrated that engineered pigments offer opportunity for improving print quality and cost-effectiveness of manufacturing.

A roundtable session featured industry, supplier and institutional representatives discussing curtain stability. Promising results were observed on pilot projects, but practical installations are necessary.

Other presentations included: coater runnability, pre-calender online measuring techniques, and the influence of the coating layer, latex, and roll covers on paper quality. A paper on printing ink developments for cold-set offset suggested the need for collaboration between papermakers, printers and the suppliers. The program ended with mill visits to MD Papier at Dachau, Haindl Papier at Augsburg, and tours of the PTS and VESTKA pilot coater. --Nick Triantafillopoulos, TAPPI Editorial Board, nick.triantafillopoulos
