The best practice is to consult your printer first. Some printers actually prefer the color swatches stay Pantone because their RIP can automatically do the correct conversion at output. Hi, yes this printer wants the colors converted to CMYK before they get them (and that has been my experience with most printers).
While most colours are convertible from RGB to CMYK, if there are any noticeable colour changes during conversion, you may need to revisit a step and adjust some of your values before converting. Inconvertible colour swatches that cannot be replicated accurately in InDesign or Illustrator will appear in the preview with a yellow warning
b) Knowing this, a reference to CMYK is meaningless. And even for the case that the object is paper: which CMYK ? RAL colors (paint) can exceed the gamut of monitors, RGB working spaces and CMYK spaces. After some attempts to find more information, it. turned out that Lab (CIELab) values for RAL are. #2 -- InDesign, when exporting to something like PDF/X-1a, will convert RGB to CMYK. In addition, this will not create additional files to edit. You can place each artboard on it's own InDesign page. (you don't even need PDFs from AI, just use the AI file) Check the PDF export afterwards to ensure colors were converted well. . 133 432 408 299 96 280 66 140
