Color workflow
- The analyzer reads the PDF in the browser.
- Ghostscript-based processing is used to calculate page-level CMYK coverage.
- Results are summarized by page count, channel averages, totals, and page-level rows.
Methodology
How the current analyzer processes PDFs and reports coverage.
This page exists to make the workflow inspectable. For a production-facing tool site, methodology matters as much as the output itself.
Monochrome workflow
- The original PDF is converted into a grayscale PDF first.
- The grayscale output is then analyzed separately with the same coverage engine.
- Mono coverage is reported independently from the original CMYK channel averages.
Preview generation
Cover previews are rasterized from the first page. Higher-density screens receive denser preview renders first, with lower-DPI fallbacks used when memory limits are reached.
Current limits
Very large or complex PDFs may force the analyzer to drop to a lower DPI. If that happens, the interface reports the effective DPI used for the successful run.
