In order for CMYK colors to display with a reasonable RGB simulation on screen you will need to create a table for CMYK-to-RGB.
- In the other application, open the CMYK Colors file located: Photoshop->Goodies-> Calibration folder.
- Convert the file to RGB
- Save the file as a TIFF file, giving it a descriptive name ( i.e. LinocolorSWAP_RGB.Tif )
- VERY IMPORTANT ! In Photoshop, open this file and do: Image-> Mode-> Lab Color
- Save the file in the Raw format, using the same dialog box settings shown in the previous section and name the file something appropriate
This creates a table for use in Photoshop when displaying CMYK files separated using the new clut from your other application. Again you use this table by loading it in the Separation Tables dialog box by clicking the load button and opening the file you just saved
Once both tables are loaded in the Separation Tables diolog box you can create a single bi-directional separation table that Photoshop can use for both RGB-to-CMYK and CMYK-to-RGB conversions. Simply click the Save button in the Separation Tables dialog and save the table with a descriptive name ( i.e. LinocolorSWAP_PS.table ). In addition, when you save these tables out in Photoshop 5.0 and above, you create an ICC profile. You can now load this as a table or as an ICC profile whenever you want to use this conversion algorithm for both separating RGB or viewing CMYK files.
