Anything added to an ink will effectively dilute the pigment load. Even if the additive itself does not change the tack ,you will have a decrease in tack as a result of the thicker ink film you will need to run to maintain the same density. If added in very small doses the product will ultimately lower your inks working tack. Im not familiar with the product and the recommended dosage, but there is the possibility that the product contains a fast acting dryer that will build tack very quickly, allowing your ink to reach pre additive tack levels even at thicker ink films. Perhaps a company rep for the product will speak up and offer more insight.
