Heidelberg - rollers or runners problem?
I’m getting light inking on every 3rd print with my Heidelberg.
Good - good - light - good - good - light
I know there is something eccentric with either the rollers or runners because if I stop the press on top of the form and spin the roller by hand I’ll only smear on half of the roller.
I can’t see any irregularity in the rollers even when I put it on a totally flat surface and roll it. And the runners measurement is less than a .001” variation when I spin it in my dial calipers.
I bought the runners on ebay, poor choice? The rollers are Syntac. Any suggestions are welcomed.
I’d also try rolling the runners on a flat surface while on the rollers, to see if the runner centers or cores are eccentric.
I’d check that the rails & adjusting cams are snug and that the arms are retracting sufficiently.
Syntac rollers have seemed pretty good to me.
