About Colour Inspector
Analyses colour spaces across all content in the PDF — raster images, vector drawings, shapes, and text. Detects DeviceRGB, DeviceCMYK, DeviceGray, Separation (spot), DeviceN, ICCBased, Lab, and calibrated colour spaces. Professional print workflows require CMYK — RGB content will be flagged. Ghostscript ink coverage data is reported where available.
