CMYK · FOGRA29 profile · 300 DPI · Ready for IngramSpark upload
IngramSpark and B&N Press print in CMYK. If you submit RGB images, their system converts them automatically — but the conversion can shift your colors in unexpected ways. Converting yourself gives you control.
This tool uses Ghostscript — the same engine professional print shops use — to convert every RGB image in your PDF to CMYK using the FOGRA29 (ISO Uncoated) color profile, which matches IngramSpark's printing stock.
KDP Print actually prefers sRGB — selecting KDP above will convert your file to sRGB instead of CMYK. This matches Amazon's printing workflow and produces more accurate colors on KDP paperbacks.
Your file is uploaded, converted, and deleted. We don't store your manuscript or cover art. Files are permanently wiped from our servers within 24 hours.
18 compliance checks — fonts, bleed, PDF/X, image resolution, TrimBox, metadata, and more. The check is free.
