Colour profile of your poster

When your poster is ready for printing, you have to be sure it has a CMYK colour profile. This is a colour profile that is suitable for print and ensures that the colors are displayed correctly. You can read more about CMYK in the Science Poster Design Guide, chapter 6, or check for example


Check it for the tool of your choice:

  2. Go to File.
  3. Go to Document Color Mode.
  4. Choose 'CMYK Color'.

  3. In the 'File Format' dropwdown menu, pick PDF.

  6. In the top navigation bar, go to Edit > Preferences.
  7. Choose 'Color Management'. 
  8. At 'CMYK' select the appropriate settings for your printer. If you do not know, ask your printer.
