Abstract

The generation of paper cockle is a very severe problem for thermal ink jet based copiers/printers, particularly for high area coverage images. The problem manifests itself as unacceptability of output sheet quality to the customer or as extremely difficult paper handling concerns, particularly for duplex copies. One method of preventing cockle, which is used in the commercial paper coating industry, is drying the paper while under tension. This approach is adequate for continuous roll stock, but has its practical limitations when considering cut sheet applications.
