Thread: komori l420 damp problems

Hi Richard

The rollers actually look fine nice and matt looking. I know the rollers we have at the moment that we had re-covered came back with black rubber and i thought that the metering rollers are meant to blue, does this make any difference as long as the shaw hardness is correct?

Cheers

Glenn

Glenn,

I run a lithrone 420.
The damp rollers are kinda touchy. I had problems when I first started running this press. I was running a 628.

If you have decent rollers. Try a light setting between the metering roller and the chrome roller. Start with 2mm instead of 3mm. Also use 2 clicks for pan roller to metering. The basic setting for the other lithrones are 4 clicks.
Also when the press runs longer the rollers gets hot and the roller will swell up and your contacts between the rollers with get tighter a little.

Just reread this thread and thought I'd let you know about our shift away from IPA

2for1 fount replaces IPA (big cheer from the 'green' party) as well as the fount additive we used to use.

Results are very good, although we still have to lift damps up through the day.

Print quality is sharper, showing more detail in shadow areas, the severity of picture-framing on the impression cylinders is much reduced. I even reckon there is more gloss to the print.

A plus is the that it works out a tad less expensive than the IPA/Varn Supreme combination.
