Using Preview Profiles for Soft Proofs

Preview profiles allow soft proofing of image files in DeviceLink profiling and Multicolor printer profiling, without the need to actually convert the file. Preview profiles can be created together with DeviceLink or Multicolor printer profiles by activating the option Save Preview Profile (see screenshots). Subsequently they can be managed like any other profile using Profile Manager. Preview profiles will receive the suffix ‘preview‘ in their profile name and are saved in the folder Profiles (macOS) or color (Windows), (macOS: /Users/Username/Library/ColorSync/Profiles, Windows: C:\Windows\System32\spool\drivers\color). Right clicking on the preview profile and selecting the menu entry Show file in the context menu will take you directly to the location of the selected profile.

Creating preview profiles in DeviceLink profiling.

 The created preview profile is a special printer profile which you can use as soft proof profile (in Adobe Photoshop for example) for any DeviceLink combination (RGB-to-CMYK, CMYK-to-CMYK, CMYK-to-Multicolor etc.).

Note: The creation of preview profiles is not available for DeviceLink profiles using more than four channels in the source color space since only preview profiles of the color spaces Gray, RGB or CMYK can be used in Photoshop. Multicolor printer profiles are not affected as their preview profiles are allways RGB profiles which can be used in Photoshop.

Example: If you would like to adapt your RGB image data in RGB mode to the desired CMYK printing condition, you can use the preview profile of your RGB-to-CMYK DeviceLink as soft proof profile in Adobe Photoshop to check how the image would look like after the conversion. This allows specific RGB adjustments without the need to convert the RGB file early on. A preview profile is a very useful feature, particularly in view of storing RGB image data in media-neutral workflows.

Preview profiles can also be created for Multicolor printer profiles which allows a true color simulation of the color representation prior to application of the Multicolor profile. Although Adobe Photoshop CS4 or higher is able to convert image data using Multicolor profiles, the display of multichannel files is not a true representation. So far, a true color representation of multichannel files is only possible using additional plug-ins and causes an increased workload. The preview profile function generates an RGB printer profile which features the same color properties as the original Multicolor profile. Use this preview profile on your original image data for soft proofing. More information on how to use preview profiles of Multicolor printer profiles in Adobe Photoshop can be found here.

Note: Preview profiles are only intended for soft proofs and should never be used for the actual conversion. A preview profile provides an excellent visual preview of the expected result of a DeviceLink conversion. However, the special features of the DeviceLink, such as preserving color purity, cannot be 100% emulated.
