    Hey guys,

    Im new so bare with me...We just got our printer in last week. So I'm just starting to play with different materials and profiles. Im printing on a 13 0z glossy banner material. When the print comes out the ink is very "dotty" (if you can understand what I mean). I am not getting a consistant printed color. What could be the cause of this and how can rectify the issue. I want to get the issue figured out before printing at full scale size. Thanks guys! I really appreciate the help.

    Maybe up your heat settings to close to max to start, or it might just be the top layer of material,try pulling a bit more through.

    Im using a generic banner profile that came with versaworks and the material is emerald gloss banner 13 oz. Ive tried a few different profiles and all have this effect. Heat is set at max 112

    Go to the manufacturers web page and see if they have profiles for the media you are using. It sounds like a profile issue to me. If they don't have a profile then you may be able to use one from another manufacturer like Oracal.

    Set your heat to 90, dryer to 94, try that, also try gcv profile and also sign and display.

    Worth a shot

    There can be many causes of 'dotty' or speckled solids. In addition to the things already mentioned (temperature settings), these can include:

    Bidirectional alignment - this should have been performed by the installer of the printer. You can run a user-level bidi calibration as well (check your Roland user manual for instructions for this).
    Head height - high setting will likely show more speckling in solids.
    Head speed - slowing down the carriage speed while printing can reduce the appearance of spotty solid colors by improving drop accuracy.
    iCC profile - if the speckling is more visible in brighter colors (highlights), the ICC profile may be using more K dots than it should, resulting in speckled highlight colors. If you have the tools to build profiles you can create your own ICC profile so to improve this.

    The other option here is to try other media profiled from various sources like manufacturers of media, or distributors, or any other sources thar you can find, and then test.

    In general, scrim banner medias tend to hide print artifacts more than most other medias do, so if you are having problems with banner media, you may also have similar issues with other media types too. Hopefully you get this sorted out. Good luck.

  9. I know this may sound stupid, but the first time I ran banner through my first Roland printer, I had similar results.

    I found it to be that I had put the roll of banner on the printer the wrong way round so it was in fact printing on the back of the material.

    All the banner material I have used has the printable side on the inside of the roll, not the outside in the way digital vinyl does.

    I know this is a long shot, but I had a similar problem when I got my first machine.
