Hi all,
I'm hoping someone can give me a bit of insite into moire. We had to pull a job off press today that had moire in fleshtones, obviously moire between the Y and M plates. We're going to try putting the Y plate at a finer screen than the CMK plates which I have read helps. Other ideas to help? We're currently running Y at 0 degrees, C at 15, M at 75, K at 45 degrees. Swap the angles of M and K?
My larger question though is what, if any press variables can produce moire? This job was in good register, so that doesn't appear to be it. Are there blanket/packing/roller/sequence/trapping issues which can cause or make moire worse?
Thanks,
Matthew Larmour
