(When the file is saved in certain standard PDF/X formats, the color profile will always be embedded.) Basically, while embedding the color profile is not an absolute requirement in terms of the technology used (if the employed color profile was otherwise suitable), however, without such an embedded profile, the recipient of the file cannot verify that the correct color profile was used. You can chose if you want to embed the color profile into the file. In Adobe applications (Photoshop, InDesign, Illustrator), you will access the central color management settings through the Edit > Color Settings… menu item. Obviously, if you want the display settings to have a noticeable effect on your monitor, you will need to have your monitor calibrated with a measuring instrument (spectrophotometer). In addition to selecting ICC color profiles, you can use these settings to adjust other options that can have a significant impact on the color separation of your files, and the coloration of the images displayed on your monitor. In every professional software applications that are suitable for producing print-ready materials, you can access color management settings handled by the operating system. Since parameters for offset printing are set in accordance with the ISO 12642-2 standard, you will need to use the related standard color profiles. This will warn me if Lab or RGB are used by an image link or any InDesign content such as frames or text.Selecting the correct output ICC color profileįor typographical reproduction it is always important to set an ICC color profile in your programs that is suitable for the given printing technology and the substrate (paper). I’m going to select RGB and Lab modes here – although Lab is less common than RGB it still presents a problem in a print-based workflow. There is an additional section for ‘Spot Colour Setup’ which gives even greater control over spot behaviour. This gives you flexibility over intentional use of Spot Colours.
In commercial Swatch Libraries, such as Pantone, swatches are often specified in Lab or RGB colour for greater accuracy – because these are set-up as ‘Spot’ colours and render to their own colour separation they are allowed to pass by the Preflight Profile unless the ‘Spot Colour’ checkbox is selected. This applies to any InDesign content and not just Image Links – use an RGB Swatch to colour text, for example, and this will be flagged.
Under ‘COLOUR’ is a section for ‘Colour Spaces and Modes Not Allowed’ – here we can specify which colour modes will be flagged by our profile as a potential issue.
