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.
