I read with interest Ray Nichols’ prior post regarding the resurfacing of his SP-15’s ink drum. The drum on my own SP-15 is also scratched, presumably from the previous owner’s use of the automatic washup system (the blade was missing when I bought the press, and I haven’t replaced it). The scratches on the drum are not terribly deep, but can be felt when running a hand lightly across. I’ve always felt that my press requires more ink than it should to achieve decent coverage. I’ve never used another SP-15 other than this one, but both the No. 4’s I used in the past did not need nearly as much ink as my press seems to. Additionally, the rear form roller, which comes in contact with the drum, never seems to have as much ink on it as the front form roller, until about halfway through a day’s printing, when by then there is quite alot of ink on the press.
My question is– does a scratched drum contribute to inking problems? I would be very interested to know if Ray and any others who have done resurfacing have noticed consistently improved results.
