When generating a DeviceLink for a given output device type, such as an offset press or an ink jet proofer, ColorFlow provides a default DeviceLink method and other settings for transforming CMYK color values, which are tailored to the device type and device condition. It's recommended that you start by generating a DeviceLink with the default methods and examine the color output; If the result isn't ideal, redefine the DeviceLink to select a different method and exam the color output again; Then, if you want to produce a closer color alignment, adjust the DeviceLink.

Requirements: You must do a full color characterization in order to generate a DeviceLink profile.

  1. From the DeviceLink Method list, select a desired generation method (depending on the device type, some options may be unavailable): 
  2. In the  Rendering Intent  list, choose the gamut mapping that should be used when mapping colors from one color gamut to another: 
  3. Depending on the DeviceLink Method you selected, the available options are displayed:
  4. For the Full Reseparation DeviceLink method with Relative Colorimetric rendering intent, to perform perceptual-like gamut mapping of the lightness scale, select the Black Point Compensation check box. 
  5. For the Ink Optimizing Solution DeviceLink method, to achieve a closer color match to your source color space while achieving ink savings (not applicable to color inputs and non-curved outputs), select the Target Simulation or Color Space Conversion check box (depends on whether you are in the PCO or SCO). For curve-controlled devices, selecting this option allows gamut mapping to occur between two different color spaces.Otherwise, ink usage is optimized but colors are not visibly converted.
  6. To maintain 100% black and zero output for zero input tint values, select the Maintain Rich Black Purity check box. For example, for a CMYK (50, 30, 0, 100) input tint, selecting Maintain Rich Black Purity allows you to retain 100% black and 0% yellow output tint values. 
  7. Click OK.
