I need to convert RGB tiff files to CMYK tiff files.
I'm able to do this using:
Atalasoft.Imaging.AtalaImage img = new Atalasoft.Imaging.AtalaImage(filename);
img = img.GetChangedPixelFormat(Atalasoft.Imaging.PixelFormat.Pixel32bppCmyk);
// img.ColorProfile = new Atalasoft.Imaging.ColorManagement.ColorProfile(iccFilePath);
img.Save(filename, Atalasoft.Imaging.Codec.ImageType.Tiff, null);
But the resulting Tiff file looks different then input (all colors have "washed" effect).
I tried using ICC profile, and I get the same results.
When I use photoshop to do the conversion, the output CYMK looks identical to input RGB using default icc from photoshop or my icc file.
Am I doing something wrong?
