Summary:
One of the factors in the increase of productive time in printing today is paper, which is truly better than ever. Gains have been made throughout the paper industry in step with printing equipment design. In the last decade these gains have brought about better uniformity in basis weight, caliper, and finish, and have improved cleanliness and printability. The paper presents a less-technical explanation of how these improvements in paper have been made. The explanation begins with fiber strength and brightness and continues with modifications of refining, newer drying equipment, upgraded inspection for quality control procedures, new instrumentation, and a virtually new approach to the finishing of paper. Stock has been upgraded to such a point that downtime as a result of defects is no longer the menace it was a decade ago. Applications of these many new developments give promise of even greater things on tomorrow's printing papers. In large part these are the result of cooperation between associations such as TAGA and paper trade groups.
