This tool goes beyond a simple RGB or CMYK flag and identifies every colour space resource used in your PDF, including DeviceRGB, DeviceCMYK, ICCBased spaces, Separation, DeviceN, and Indexed colour spaces. It breaks down the results per page so you can see exactly where each colour space appears.
Different colour spaces reproduce differently on press, and some like Separation and DeviceN require special handling for spot colours. Identifying these resources before printing ensures your file is set up correctly for the intended output device and avoids costly rework on the press.
An ICC profile is a file that describes how a device interprets colours. In PDFs, an ICCBased colour space uses a profile to define how colour values should be rendered, ensuring consistency across different devices.
Separation colour spaces represent a single spot colour plate, while DeviceN can contain multiple spot colours in one space. Both are used for special inks like metallics, varnishes, or exact Pantone matches.
Spot colours are pre-mixed inks applied individually rather than built from CMYK. They reproduce a wider gamut than process printing and are required for brand colours with strict matching requirements.
This typically happens when pages or content blocks are combined from different source files. Each source may have been set up with different colour settings, resulting in a mixed-colour-space PDF.
An Indexed colour space maps colour values to a lookup table rather than using a full colour model. It is often found in files derived from images with a limited palette, such as GIF conversions.
Quickly check whether your PDF uses CMYK or RGB color spaces — important for print accuracy.
Run a comprehensive preflight check on your PDF to see if it's ready for professional printing.
Check whether all fonts in your PDF are properly embedded — a common requirement for commercial printing.
Check the effective DPI of raster images in your PDF to ensure they meet print resolution requirements.
