    When I render to bitmap the color changes.

    Thanks for any ideas as to why?

    The colour changes on your screen? Or the printed colour changes?

    If it changes on your screen, I would suggest opening a support ticket or bug report with SignLab so they can fix the problem.

    If it changes the printed colour, it's because Versaworks processes vectors and raster separately, so you need to ensure that you're using the same settings for both. Here's a doc from Roland that explains it.

    EDIT: it could also just be that you're rasterizing something that has a spot colour in it. That could potentially change how it looks on screen and would more than likely change how it prints.

    Been using signlab since 6.0 (8, 8.1,9) and am now using 9.1 for edge2 and 10 for our mimakis.

    It's a vicious circle, but the problem probably lies in the profiles/calibration of your monitor & signlab.

    Signlab uses different profiles for bitmaps (even rgb & cmyk are different) and vectors and both need to be calibrated to your monitor (you will need a calibration device like x-rite, spyder, etc.) and usually just defaults to a generic rgb profiles for both. This gets even more complicated when you try calibrating your monitor to your printer, as now you're dealing with 2 different types of light (subtractive rgb vs additive cmyk).

    Another issue is that signlab still can't render cmyk/spot color vectors into cmyk bitmaps(only grayscale or up to full color rgb) nor can it edit the cmyk bitmaps either.

    You'll also have to keep in mind that these values change (ever so slightly) over time as your monitor and printer wear out.
