Rembrandt bought a printing-press for his house in the days of his early prosperity, and continued to produce etchings (always so called collectively, although Rembrandt mixed techniques by adding engraving and drypoint to some of his etchings) until his bankruptcy, when he lost both house and press. Fortunately his prints have always been keenly collected, and what seems to be a high proportion of his intermediate states have survived, often in only one or two impressions. He was clearly very directly involved in the printing process himself, and probably selectively wiped the plate of ink himself to produce effects "surface tone" on many impressions. He also experimented continually with the effects of different papers. He produced prints on a wider range of subjects than his paintings, with several pure landscapes, many self-portraits that are often more extravagantly fanciful than his painted ones, some erotic (at any rate obscene) subjects, and a great number of religious prints. He became increasingly interested in strong lighting effects, and very dark backgrounds. His reputation as the greatest etcher in the history of the medium was established in his lifetime, and never questioned since. Few of his paintings left Holland whilst he lived, but his prints were circulated throughout Europe, and his wider reputation was initially based on them alone.
