I’m confused by a conversion I’m trying to do from RGB to CMYK.
We have a press profile that we commonly convert our work to. If we open the profile in ColorThink and do a 3D compare to US WebCoated SWOPv2 it exceeds the SWOP profile in every direction. Thus I perceive that our profile has a greater color gamut than SWOP.
I then bring in an image into the 3D view, in this case the ducky.tif image from the Photoshop samples folder. I can see that most of the image is within our profiles’ color gamut but there is alot of pixels that lie outside the SWOP gamut. From seeing this, I can assume that when I convert the image from RGB to our profile that there will be little change in the color. When I convert from RGB to SWOP I should see a greater shift in colors.
So I go to Photoshop. I convert the image to SWOP and there is very little change. I convert the image to our profile and there is a much greater change.
If I’m seeing that our profile has a greater gamut, especially in the color area of this picture, why is it not converting as well?
I’ve tried restarting with the profile’s measurement data and recreating a new profile using different ink density/GCR setups and they make very little difference.
Any help that anyone could give me would be greatly appreciated.
