tub sized

Paper that has been sized by passing the web through a size press. or by dipping the waterleaf sheet into a tub of size by hand, or by carrying it through the size bath between two felts, which are either perforated or have an open weave so as to allow the excess size to run off during passing through the squeeze rolls. Most papers of high rag content are tub sized and the sizing is sometimes done with the use of 100% animal gelatin, followed by air drying. If done properly. a tub-sized paper is stronger than a similar paper that is internally sized. (17 , 156 , 198 )
