GCRflow: PDF gray component replacement in your browser
GCRflow is a browser-based PDF Gray Component Replacement service. With ColorField 1 you choose the GCR strength, from GCR0 to GCR100. Rich-black boost and Low Gray Enhancement are optional. Official presets convert to GRACoL 2013 at TAC 320%; custom presets can use GRACoL 2013, Fogra 27, Fogra 39 or Fogra 51 and a total ink limit from 260% up to the profile's maximum. RGB with an embedded ICC profile is converted per object using that profile; untagged RGB defaults to ECI-RGB V1.0 and can be switched to sRGB, Adobe RGB or Display P3. The output is print-ready: RGB is converted to CMYK, total ink stays within the chosen limit, pure black text stays single black and an output intent is embedded. Pricing: see the Pricing page.
