The fibrous composition will depend largely upon the price. An all-rag paper is a splendid white paper, soft to print upon, pleasant to handle, very durable, and a type of moderate colour printed with a good black ink gives a very rich appearance on such paper. Hand-made, Dutch hand-made, mould-made, and machine-made rag papers are the papers for very special editions. Special moulds or dandy rolls are sometimes made for these papers to secure a distinctive appearance.

A blend of chemical wood and esparto, skilfully manufactured, produces a very good printing paper for all ordinary purposes, and papers composed entirely of chemical wood may be good or indifferent according to the treatment and skill devoted to their production. Sulphite papers tend to be harsh and transparent, but a mixture of soda pulp partly counteracts these faults, and even if it is not quite as soft as an esparto mixture, excellent results in
