Converting rgb tif files to cmyk files

Looks power point is not able to export tiff into CMYK, only RGB
For this process it is important to have the files which define the colour spaces(?)

 for file in *.TIF; do convert "$file" -profile sRGB_v4_ICC_preference.icc -profile APTEC_PC11_CCNB_2023_v1.icc -density 300 -resize 2550x3300 CMYK_"${file/.TIF/.tiff}"; done

Parameters:

  • -density 300 pixels per inch
  • -resize 2550x3300 scale to A4 with a 300 pixels per inch density
