    We have a big demand in soft feel acquis coating. We get the first pass off no problems. When we flip it on the second side. We get bouncing at the head stop pretty bad. Seems to bounce on the gear side. We have tried different coating. Waiting extra time to let it dry( makes the problem worse). Powdering the heck out of it. Drying temps. Adding crosslinker. This happens and text weight stocks and cover.

    When you say "soft feel" coating are you referring to a satin or matte coating, or are you talking bout soft touch coating that has that soft to the touch raised nap finish?

    The sheets come down the board fine hit the head stop and about every 5th sheet bounces a good inch or two. We end up either running 5k hr to keep the bounce down enough to run or if we run 2500 sheets turn it immediately and run then back through that works also
