Special thanks to Gerald Lange, Fritz Klinke, and others for their very helpful posts/articles here on the Blog re: this topic. The remaining issue, […]

Reprex No. 2 Missing drive gear
I recently acquired a Reprex No. 2 [No. 1] proof press. While everything on this Reprex appears to be in excellent shape, it is in fact missing the drive gear on it’s form roller. The original manual I have specifies that there should only be one drive gear, and the part number for this gear is […]
MoreMore TagReprex II question
I need some feedback please. We use a Reprex II in our studio. During the last class, last 15 minutes the carriage would stop mid travel like it hit a brick. Checked all the usual culprits- something on the gear track, high furniture, bad lock up, etc. Even changed some furniture to make sure none […]

This display ad appeared in most issues of Graphic Arts Monthly, vol. 1, 1929, but does not appear thereafter. Neither was it advertised or mentioned in The Inland Printer or Photo-Engravers Bulletin before, during, or after 1929.

MoreMore TagSetting Impresion Bearings
Hello All, I’m having a grand old time trying to set the bearings on my Challenge 15mp and it’s been over two weeks of adjusting, proofing and re-adjusting. The main issue I’m finding is that my carriage shifts once the rear impression bearing comes in contact with the rail, causing the rollers to rise and […]
MoreMore TagCHALLENGE 21MP
Hi All, I am helping to restore her Challenge 21MP. It seems the inking rollers and assembly are missing. Maybe dutifully taken off the press after printing and forgotten about. The cores and rubber are not as much of a problem to replace as the gear and other metal parts that attach to the rollers. […]

Leslie William “Lex” Claybourn (1883–1956) was a printing process pioneer who was issued over 200 U.S. patents. Like Horace Hacker and R.O.

MoreMore TagAsbern vs Vandercook
Hello I’m a graphic designer in Spain. I’m planning on setting a press here. I’ve been offered an Asbern AD1 and a Vandercook Universal I. The Asbern is cheaper but I don’t really know if the Vandercook is much better, if it’s really worth paying more. As you can see, I have no experience in […]
MoreMore TagI am looking for info on my Potter Press
I’ve had a Potter #2 for about 10 years. I’ve happily been doing small runs of woodcuts and engravings with it. Still I’d like to make it work like it once did. I’ve got some beat up grippers, but that’s the extent of it. I’m looking for information as to how these presses went together. I have questions, and possibly […]
