Processing of RGB / Lab input images

How to configure color management for grayscale input pictures

RGB / Lab processing options

Where: Channel | Color Management | RGB/Lab tab

This tab contains color management settings for RGB and Lab input files.

By choosing Don’t Color Manage, the color space remains unchanged. By choosing grayscale conversion, you may click the Advanced Options button to choose the amount of contrast enhancement and red, green and blue ink mix percentages. The default values are R=30, G=59, B=11. Also, when converting to grayscale you may adjust endpoints by clicking Endpoint Adjustment.

By default, the selected input profile is applied to all RGB and Lab images in the channel, provided a profile hasn’t been embedded in the input file, in which case that profile will be used instead. In order to ignore any embedded profile in the input files, tick the corresponding check-box to ensure that Color Factory will apply settings from the selected input profile to all RGB and Lab images in the channel. To embed the output profile in the processed output file, tick the corresponding check-box.


When converting from RGB to RGB, you have the option of enabling Gamut Management, which makes it possible to have Color Factory make a test conversion of the RGB image in order to give an indication of the result of a future conversion of the output RGB image to CMYK. In the Gamut Management dialog box you may choose a CMYK profile and the type of rendering intent, and choose the measures to be taken if a certain amount of pixels are out of gamut. One option is to edit the image text of the output file to make a note that a future CMYK conversion of the image will produce a large amount of out-of-gamut pixels.

RGB to CMYK conversion

When converting from RGB to CMYK a few extra options become available:

Force white point to zero dot: Certain ICC profiles have an absolute white level slightly higher than zero. By enabling this feature, Color Factory will override the profile setting and adjust the image white point to zero.

Rendering intent: Here you may choose the method used for the CMYK conversion. For images on print, Perceptual or Relative Colormetric is recommended.

By choosing SmartRender™, Color Factory will apply the rendering intent selected by clicking SmartRender™ Settings. Then, the result of the rendering will be compared with the original input file. If more than the specified amount of pixels is out of gamut, Color Factory will process the image according to the desired procedure as specified in the SmartRender™ Settings dialog box.
