I find that your raw supplies make a real difference. We run an ink that, depending on the screening, gobbles up water significantly. This leads to some...unpredictable....dot gain in certain screen combinations. If I ran a blue, a purple, and a red in line with each other, the magenta ink...

Other than the fact that so much of this goes over my head..... The simple fact is that we are hunting for a grail here. With customer expectations and market materials available, we will always be adapting to new conditions. Constant adaptation is no basis for a stable standard, IMO. At the...

If dampening doesn't solve, it may be your paper stock is 'bleeding'

I think I'll toss in at this point.... I agree wholeheartedly that ultimately once the press is set up properly, all you should need to do is run to SD. That being said, I have found that when the operators have a full knowledge of the entire process, they are interested in knowing what the...

Well, if running less fount works better, all the power to you! We had a fountain solution from Huber at one time. Recomended dosing was about 3 oz/gallon or less; we couldn't get the plates to run clean unless we ran up at 5 to 6 oz/gallon. But when we did - amazing! Minimal piling, minimal...

And just a side point....why isnt the printer doing his own scans. Probably more helpful for him to scan and adjust as he prints that for you to be coming back to him later....

An option, albeit a not very good one.... Raise your forms of the plate till they are barely touching it, like i mean the hint of a stripe. When you start printing you will have to flood the train with ink in order for it to transfer (same with the water system). But minimizing that contact...

The last thing to change is usually the problem....you changed your blankets, now you have problems....so...blankets! Get the tech in

Just throwing this out there, but.... do you have a short smoke tunnel on exit of dryer? I have seen marking come from the web exiting the smoke tunnel and still fluttering. It would look like it was coming from your dryer but is actually just afterwards.

Leaving Erik's usually fascinating comments on the nature of ink aside..... If it is one corner of the print, probably a low blanket - mottle with heavy coverages is a very typical pressure problem that has nothing to do with emulsification. Paper is also an option, however, you could rule...

Score of 3.... These are always fun, but so highly inaccurte. I remember reading somewhere that since your brain works by electro-chemical impulses, it is actually possible for the meal you have just eaten to slightly skew the way your eye communicates with the brain, hence changing colour...

Too high a humidity level does affect ink/water balance....it increases the emulsification. That excess emulsification may require running a thicker film to achieve same apparent results, so corresponding increase in ink consumption. As for humidity of the paper board itself, it ultimately...

I be been there and true that and will never try again. I leave fount formulation to fount formulator

Interesting that you mention summer... I am with everyone else, if your settings are good, it is more than likely the ink. If your manager doesn't mind spending the money, get a better ink. Get the company to come ina nd look closely at the situation. And if they tell you it is anything other...
