Soft Proofing

Display Soft Proofing

Siril supports soft proofing. This provides a visualisation in your monitor's color space of what your image will look like when printed on a specified press standard. To use output device soft proofing you must specify a soft proofing profile in the Settings dialog.

If no output device profile is specified, or if it is made inactive using the preference check box, soft proofing will use the display profile as the proofing target. This enables the gamut image check in the Image Checks menu, which shows the pixels that are outside your display's color gamut. When gamut checking is active, out-of-gamut pixels will be shown in garish magenta.

Press Export

Siril does not support exporting in CMYK formats for print / press purposes. Most photo printing services expect images to be provided in RGB formats and printer drivers do a much better job of converting RGB to a blend of the specific inks used by each printer than a simplistic application-level RGB-to-CMYK conversion. Unless you know exactly why you need to convert an imge to CMYK, you almost certainly don't need to. However, in order to minimize gamut clipping when your printing service converts the image to a CMYK profile for printing, it is worth using a wide gamut RGB profile such as the built-in Rec2020.
