    Print Grayscale photo in VP540

    Hi there,

    i΄m going nuts on trying to print a grayscale photo in my VP540. The prints are always greenish or for the magenta side. How can i get a good gray from this printer?
    Another problem i have is that my prints are much darker when they come out of the printer that what they seem to be in the screen.
    I΄m using Versaworks and Triangle inks

    thanks in advance

    thanks for the help. What i΄ve understood from that thread is that if we use color charts we can match and get some better colors. but this is for vectors, not for raster files. or did i miss something

    Page two has the answer:

    When working with black and white, or greyscale raster graphics you can
    change the default settings in Roland VersaWorks to use only the black (K)
    inks to recreate grayscale images.

    To do this open Roland VersaWorks and navigate to your Job Properties
    window. You can get there by double-clicking on the job in your Queuee
    window or by selecting the job and clicking on Job then Settings. Once
    there, select the Quality tab (second tab down on your left side). At the
    bottom of this screen you will see Color Management. Change the selection
    in the Preset to Density Control Only. This setting will typically be set as
    Pre-Press US by default.

    Note that you can also apply different settings for raster and vector images
    by selecting Custom and clicking the Properties button. This will open
    the Color Management Properties dialog box where you can select the
    Matching Method for raster and vector graphics. Select Calibration and Ink
    Limit for the portion of your design that contains the grayscale data.

    This method will always produce neutral grays but since you are bybassing
    the ICC color workflow, it may not be suitable when you have designs
    composed with both grayscale and color images. Also, since you are using
    only one color (black) to compose the image, the output may look grainier so
    it is recommended to print at a higher resolution.

    hmmmm... usually work on my XC? I've printed grayscale images on canvas and they looked amazing. Maybe someone else has some ideas.

    I recently had a request for printing black & white photographic images and was concerned that I wouldn't be able to achieve acceptable results but got great prints on the first try. Took the customer supplied color photographic images into photoshop & changed the color mode to Grayscale then in Versaworks I selected "Preserve Primary Colors" so that it would only print using the black ink, I also selected "High Quality" 1080 x 1080 DPI on the print quality to compensate for the few deflected nozzles on my black print head. Prints came out beautiful, no off color hues at all, this was done on a Versacamm SP-300V but the principle remains the same so should achieve the same results on the VP.

    well i managed to solve part of the problem. I was able to produce some nice black&white prints exporting in grayscale from the photoshop. The problem now is i have a color element in the photo. Grayscale background with a kid with a yellow basketball equipment. So grayscale from photoshop is out of question.
    Tried some more times and i was able to print a sort of grayscale but much more darker than the other and not so good in my opinion.

    Anyone?


    thanks in advance

    Just wanted to say thanks!

    We were running Wasatch SoftRIP and for the life of me I couldn't not get grays to print gray. SO we upgraded to Versaworks and still had the same issues with grayscale images. This trick saved the day. Talk about months of stress off my shoulders!
