Although we have worked for years on a 10 x 15 C&P, only recently we have started doing more than cuts and proofing on a Vandercook Model 3. Obviously, there is something we missed given problems we encountered in a recent job.
We prepared a form for printing on the Vandercook. This was a 9” x 12” poetry broadside consisting of one column of 18-lines roughly 24 picas wide of hand-set, 14pt Bernhard Modern with 2pts of leading between lines and 12pts between each three line stanza. A second column included an 18pt head, 3 lines of 14pt Arrighi in a colophon, and a pressmark. All of this was planed and locked up in the press bed on the bed sheet with six quoins and several good-sized piece of decent wood furniture. It was a sound lockup, no bulging, firmly on the bed, everything nice and tight, but not squeezed real hard.
The problem we encountered was that after 20 to 30 impressions the spacing began to lift—leads, word spaces, etc., all of it began to creep up. If we continued, eventually the words spaces started to contact the form rollers and started to appear on the sheet.
Has anyone else experience this problem? Should we have used a chase in the bed to lock up the form? Do you think we were not locking it up tight enough? Or too tight? Any insights would be appreciated.
