Paper used for printing, writing, and cultural purposes. Smook defines it as "white, uncoated printing and writing grades which contain no more than 25% mechanical pulp in the furnish" (p. 295). Most furnishes, he says, are wood-free, but he does not indicate whether this only means only mechanical pulp or none at all. It should be noted that terminology is not standardized in the paper industry. Each mill, in a sense, speaks its own dialect. A similar situation is found in hospitals and binderies.
