INX

[Printman673]

We are having alot of trouble with INX inks, we are looking to change to Sun Chemical anyone try these inks. They will be UV only as we're are a full UV shop. If only used water based but found we needed alot of additives

Ran conventional sun chemical ink for years, never had an issue with it.

Try Wikoff inks - great pigment load in S. Carolina.

Hi, we have been on INX LEUV inks for 8 months now and have no problem. We run our water chemistry at 5-5.5 PH,with a German Hardness of 12 from the RO to press the our fount is dosed at 3% we don't run alcohol .
I have tested TOYO,SUNCHEM,HUBER and SEIGWERK inks with varying results.
We run two XL106 8p,we are in good copy for 35-50 sheets and will do on average 30-40 Makereadies per 12hr shift. All curves and pre-sets are optimized to make this happen.

If you are considering the switch to Sun Chemical for UV, many pressrooms find them to be very stable and reliable. However, as Marioprint pointed out above, your current struggles with INX might actually be a fountain solution chemistry issue rather than a flaw with the ink itself.

Before going through the hassle of completely changing ink vendors, you might want to look into the following:

• Check Your Water Chemistry: UV inks are very sensitive to the ink-water balance. Ensure your pH is strictly between 5.0 and 5.5, and check your water hardness (aiming for around 10-12 dH).
• Review Fount Dosage: If you are running alcohol-free, ensure your fount dosage is properly dialed in (usually around 3%). Excessive additives can definitely cause emulsification issues with UV inks.
• Run a Trial: If you do decide to test Sun Chemical or Wikoff, run a strict side-by-side trial using the exact same water settings to see if the ink performs better without needing extra additives.

Hope you get it sorted out!
