Ha yes always used to see the apprentice standing outside the maintenace shop for a 'Long Weight'

when running uncoated sheets we used to 'Dust and size' as we termed it, bascially run the sheets through the press using the blankets to grab onto any loose particles then lay down a very thin coating of ink Extender(size) on the last unit.

We used to produce our own visual Standards/ Lights /Dark colour standards. We produced them during the run by increasing/decreasing the colours overall slightly and we sent them to the customer to sign off on the tolerences. We only used them for PMS colours as trying this with process colours...

do you still have the old roller lying around, if so put it back in and see if it is level, if it is then maybe someting wrong with the new roller

Press chiller system needs rust inhibitors and glycol if its a closed system, press fountain system can be cleaned with bleach. flush system with warm water and mild bleach liquid. Make sure system has been flushed again with clean water before filling with fountain solution chemistry

If your wet trapping lamp output is not a factor, that would be more about rub, scuff, setoff, blocking etc. Things that can influence trap could be Ink Strength, Ink tack (tack sequence), Fountain solution (running too much or badly formulated), Stock absorbancy, running too much water in...
