    I've got a Roland SP-540V and I am getting these strange spots. Not the black dot, that's just from us marking it as bad. Any idea what they may be?

    Dirty media? Doesn't take much, sometimes.

    I get those once and a while on my Mutoh's. I was told by a tech that it is a humidity issue. They are supposed to run at a certain humidity and you need to purchase a humidifier and a de-humidifier to keep the spots from appearing. I don't get them enough to worry about it though.

    Either something on the media or you're using the wrong profiles for the media, but most likely yeah dirty media.

    Ok. Thanks. I'm out of 3651RA and was using 651 while waiting on my order to come it. That's probably the problem

    Bad media...Contamination of some sort from the factory. Contact your supplier they should resolve the issue by doing a RMA on it and send you out a new roll.

    Here is the photo of my media when it did that on IJ35.

    They have digital media and non-digital media for a reason. The digital version has much more care taken when being handled and far less contaminants in/on it. Although you still find problems with digital media, you'll find a great deal more on average die-cut vinyl where inks and paints aren't supposed to come in contact.

    If you have to use 651 in a pinch or some other similar....Wipe it down with denatured alcohol to clean. I
    I've printed on non-digital such as etch or diamond plate for special projects.

    Yeah, sorry...... I'm not saying you can't use non-digital medias, just that is not the intention. So, make sure you clean them super well and the denatured is a good one to use.

    That did the trick. Cleaned it real well with alcohol and the spots are gone. Thanks for the help.
