Color Management (this is a feature of the Professional Version only)

 

Image Editor provides color management on the input side as well as on the output side of the images.

 

Input color transformation

On the input side you can select a pair of icc profile to transform the image upon loading. Image Editor should work in a neutral color space which is for example sRGB or Adobe RGB.

If you have for example an ICC profile for your digital camera you can set the camera.icc profile as the “image color space” profile and sRGB as the “working color space” profile.

 

You can also check the “use embedded profiles” and leave the “image color space” text box empty. This way Image Editor will use any attached image profiles if they exist.

 

If you leave “working color space” empty then by default the sRGB color space will be used.

 

You can also set the rendering intent for this input color transformation.

 

Enabled

Here you can enable or disable an ICC color transformation on the input side of the Colour-Science Image Editor.

 

image color space

This is normally the a digital camera or a scanner profile

 

working color space

This is normally the printer ICC profile which you have to generate yourself for your printer.

 

rendering intent:

This is the rendering intend for the ICC profile color transformation. On the input side normally the “relative colorimetric” rendering intent is used.

 

The possible rendering intents are:

•        perceptual

•        absolute colorimetric

•        relative colorimetric

•        saturation

 

 

Output color transformation

 

You can apply an output color transformation to the images for printing. If now you want to enhance and print images on a profiled printer then you have to do the following transformations:

 

original image -> ( transformation sRGB.icc -> printer.icc ) -> transformed image

 

Note that for printing we recommend not to use the sRGB input profile but a generic profile which better reflects the printer gamut. We normally use the photogamut.icc profile (see: www.photogamut.org). The output profile is the printers profile.

 

Attention: you will not see the effect of the output color transformation in Image Editor. This would not make sense because the outut color transformation corrects manly printer errors. So if a printer normally would print everything bluish then the output transformed image will show the opposite yellowisch color cast.

 

Enabled

Here you can enable or disable an ICC transformation on the output side of the Colour-Science Image Editor.

 

input profile

This is normally the sRGB or the photogamut profile

 

output profile

This is normally the printer ICC profile which you have to generate yourself for your printer.

 

rendering intent:

This is the rendering intend for the ICC profile color transformation. For photographic printing normally the “perceptual” or the “relative colorimetric” rendering intent is used.

 

The possible rendering intents are:

•        perceptual

•        absolute colorimetric

•        relative colorimetric

•        saturation
