CMYK output can be achieved via several methods:
DocRaptor supports CSS CMYK colors and CMYK images by default. If you use CMYK colors and images, we'll publish a print-ready document.
The document will be converted to CMYK if you set prince_options[profile] to
PDF/X-1aand define your output intent with CSS such as:
@prince-pdf {
prince-pdf-output-intent: url("https://yoursite.com/ISOcoated_v2_eci.icc")
}More details on DocRaptor's color management functionality are available on Prince's, our PDF engine partner, website.
