Coating symposium positive despite challenges.The 20th PTS PTS put to sleep; a common euphemism for euthanasia, but also used to describe general anesthesia. 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 op·ti·mist n. 1. One who usually expects a favorable outcome. 2.

The spectrum and mix of coated paper Coated paper is paper which has been coated by an inorganic compound to impart certain qualities to the paper, including weight and surface gloss, smoothness or ink absorbency. Kaolinite is the compound most often used for coating papers used in commercial printing. grades is expected to change accordingly to meet expected worldwide market needs, with the greatest anticipated growth rates Growth Rates The compounded annualized rate of growth of a company's revenues, earnings, dividends, or other figures. Notes: Remember, historically high growth rates don't always mean a high rate of growth looking into the future. 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 latex, emulsion of a polymer (e.g., rubber) in water (see colloid). Natural latexes are produced by a number of plants, are usually white in color, and often contain, in addition to rubber, various gums, oils, and waxes. , 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 TAPPI Technical Association of the Pulp and Paper Industry Editorial Board, nick.triantafillopoulos @omnova.com |
