Important
This checker is an author preparation aid. Colour is checked inside the finished TrimBox, so crop and trim marks outside the finished page are ignored. Colour-separated text or vector content is counted even when it appears grey on screen. Embedded RGB, CMYK or spot-colour image data that appears grey is listed for review. One-channel DeviceN Black images are treated as black and white. Final professional preflight or printing press RIP analysis may still differ.
