    I believe L750s is double circumference blanket press, can you specify the exact location of streaks is it following

    1 Near gripper area
    2 In the middle portion
    3 alternate copies or all copies

    had this issue before ....try lowering roller strips of form rollers to plate and oscilators ...also try to back off one of the form rollers ....depends how far back your roller line shows up .... you will have to measure the roller circumfrance to determine which one is causing the problem
