Turbotom: Yes the Shinohara does run two different sized water form rollers. They do this to try and aliviate the banding issue they get from their dampening system. Nice thought on shinoharas side but doesn't solve the problem.
PMC:
As Turbotom noted, check plate predamp settings (one setting...
Spigot,
If the rider roller is in the up position ( the end roller collars ar horizontal) then it is bridging between the water form and 1st form.
If the rider roller is in the down position (the end roller collars are vertical) then it is just riding on the water form and not intergrated to...

The second page they measure the effect IPA has on the viscosity of fountain solution -
Note they say Alc subs have very little effect on the viscosity.
pH and conductivity will do.
Surface tension dynes/cm # would be more effective then...
No low VOC certainly does not always equal green.
EG: For instance there are leading print chemistry companies touting a wash "environmental & low/zero VOC" through the use of CAS# 64742-48-9 Napha "petroleum" hydrotreated heavy as its main ingredient.
This chemical is a non photo-chemically...
Why is it that only a few select print chemistry manufactures are listed on the data base?
Is it by option that companies show full transparency?
It would be interesting to view figures from companies that predominantly manufacture greener print chemistry and compare them against the...
Green printer,
I thought you had already been using a wash that had less than 100 gram/ liter voc ?
Wouldn't this product be suitable for such a machine ?
Possibly the best idea would be to trial specific washes on a demo Roland 700
