We require all image files for any part of your eBook to be supplied in RGB color mode. CMYK images are not accepted and cannot be delivered to our retail partners.
When you take a photograph with a digital camera or scan an image using a digital scanner, the resulting file uses the RGB color mode so you will not need to convert these files.
If you are using Adobe Photoshop and want to check the color mode of your file, you can do so under Image > Mode. We suggest making any necessary color mode conversions from CMYK to RGB before you start color/tonal changes or photo manipulation.
If you have any questions about RGB or CMYK color modes please contact our publishing team.
