Paul Signac, Trial proof of The Harbour of Volendam (Le port de Volendam), 1898
Intense dialogue
Ideally, the artist and printer worked side by side at the press. In practice, however, it was often necessary to communicate from a distance.
The master printer Auguste Clot maintained an intensive dialogue with his artists through countless trial proofs. The artist scribbled instructions or drew corrections on the proof in chalk, which Clot then incorporated in a fresh proof, and so on.
Only when the artist was entirely happy did he give his go-ahead for final printing with the words ‘bon à tirer’.
Unique collector's items
While the final edition was often printed in a run of a hundred, the trial proof was unique, which made prints like this highly desirable to collectors.
Artists and printers made clever use of this interest by carefully preserving their trial proofs and signing them for the trade.
