    On heavy coverage, the magenta prints unevenly in alternating heavier and lighter areas. We've checked out the form rollers and a Heidelberg tech shimed the rollers for us, but the problem persists.

    Again this is only in the magenta unit.

    Any thoughts appreciated

    Your oscillation could be out of time and I'd also double check your rollers again. Check the forms to distributors first, then to the plate.
    Another one that had got me before was not making sure all rollers are fully seated and bearing locks in postion.
