    Printed on perforated vinyl with a JV-150. The vinyl puckers up and causes head strikes. I've tried turning the heat way down (around 25 deg C for the 3 areas) and still have a problem. Anyone have an idea?

    verify that the media is loaded straight...increase vacuum. Are you loaded on a tur? if so, let media run free...remove any tension

    On the Mimaki JV-300, you need to adjust the head height to high by moving out the print carriage. There’s a lever on the carriage to adjust the head. It is enough to enable you to print on mesh banner material. You can refer to the manual for instructions. It’s real easy.

    I have a JV-300 but I imagine it would be similar on a JV-150.

    Thanks for the replies. It's just the vinyl that's puckering up (tunneling), not the liner backing.

    If it's tunneling it's faulty media. Window perf doesn't tunnel.
