Not sure why I always run into issues when on deadlines… Having an issue where I get an impression but there just isn’t any ink on the form and would love to hear any thoughts on what the problem/solution might be. The uneven inking is happening for the length of the press bed. Was printing […]

Inking issues on SP15
We’re completing the rebuild of an SP15 that was begun by someone else (who is now deceased, so we can’t ask them questions) and we are running into some challenges with the inking system. We were trying to set the rollers to the lightest stripe possible for photopolymer printing, which we did with the press […]
MoreMore TagWater based inks on a Vandercook?
Anyone have experience using water based inks on a vandercook? I’ve used oil based for my prints for over 20 years now but am curious about water based mainly to speed up my dry times between colors. Ive ordered some sample sizes of Graphic Chemicals water soluble relief ink line to experiment with myself but […]

I recently attempted to print a very light color of borders that extended from the top of the bed about 10 inches. The ink was mostly composed of white and revealed things about the press that are perplexing. I have several issues going on, and perhaps this was, unwittingly, a test of all of them. […]
MoreMore TagSP20 form roller issues
Recently when inking the rollers on my Vandercook SP20 I have encountered the following problems. 1) When I apply ink across the distributor roller and let it down on the form rollers the ink does not spread evenly and there seems to be some hesitation in the distributor rollers. 2) When I roll the rollers […]

MoreMore TagNew info in SP-15 roller hesitation problem
Hey Everybody, It seemed like this was going to be a workable problem, but now in actuality it has taken a turn for the worse. Today we printed a navy ink with no problem, then washed up and put PMS 874 (gold metallic) on the press. Very quickly things went down hill. I am attaching […]
MoreMore TagReplacing the wooden bushing on a Universal 1 inking drum
Well, now we have had a little practice with replacing a wooden bushing on a Uni 1 inking drum. I last posted on October 2011 when a bushing had gone on our Universal 1. We just had the wooden bushing go on our other Uni 1 (serial number: 28671). So, I thought I would share […]
MoreMore TagInking issue – Universal 1
Hi everyone, I recently acquired a Universal 1 and have a couple questions related to maintenance. I have been keeping the rollers raised by raising the lever for that purpose when the press is not in use, but wasn’t sure if I also needed to raise the oscillator and a single rider fully away from […]
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 TagUneven cylinder, SP-20
Hi all, So, the small spring on the far side of the bottom cylinder of my SP-20 broke the other day (the one next to the chain). I replaced it, but I’m still having the same issue of the cylinder being too low on that side. It’s not inking at all, and the chain is […]
MoreMore TagRattling Rollers
I was operating my Vandercook 320 and all of the sudden, the metal rollers began rattling out of control either while in print or trip mode. The rollers are shaking about so much that they’ve even been tossed off of the rubber roller carriage at times. I’ve tried oiling the press, tightening screws, but nothing […]
