Does anyone use 5-star foutain solution?

[Bloodsaler]

Our KBA C215 use this dampening soulution ,but PH value is too low.About 4.0PH.Does anyone use this product?Can give me some advice?

Why do you think the pH is too low. US founts typically run 3.8 to 4.5 on pH with a conductivity range of 1800-2500. Are you using an alcohol replacement or just alcohol on this KBA?

 

[Bloodsaler]

Our conductivity is about 1000us/cm，contain about 4% IPA.But the PH value of typical dampening solution is 4.8-5.5

A lower pH product might help you roll up faster. Is the 5 star pH level affecting your ink? Do you have printing issues with this material and the 4% alcohol like toning on press?

 

[Bloodsaler]

actually the ink doesn`t affect a lot. But the dot gain usually above 20%.

I understand. Where are you located? I may be able to send someone in to provide technical support.
