    the glaring problem that I see in the jpeg you posted is not, in my opinion, a trapping issue. You may very well have a bit of a trapping issue that just doesn't show up on the jpeg, but what I see that makes the job unsaleable is either an inking issue, or a water issue. Id be looking at the ink roller settings on the cyan unit first. Check roller settings to plate and then of equal importance check roller setting to the vibrators. Id pay the most attention the the number 4 inking roller to its vibrator setting. If the ink roller setting are good then Id check all setting on your alcohol system on the cyan unit.

    Hello every body
    Can you please send me a better photo, that I can see the lead edge and the tail edge, because I can't recognize are these lines appear vertically or horizontally.
    I hope we can solve this.
