How does the Flatten PDF Transparency work?

Rasterise each page of a PDF at the chosen resolution (150 / 200 / 300 DPI) and rebuild the file as image-only pages. This eliminates every potential transparency / gradient / live-text issue at the cost of giving up text searchability and accessibility (the result is essentially a flattened picture of each page). Useful for print workflows targeting older RIPs or proofers that can't handle PDF 1.4+ transparency, or for redacted documents where you want to make sure no underlying object can be extracted. For most modern presses, your designer's native flattener (Acrobat Pro / InDesign Output Preview) will produce a smaller file with selectable text — only use this fallback when the source app isn't available.

Frequently asked

No. Flattening to images destroys the underlying text objects. To preserve searchability, run OCR on the flattened result via OCR PDF.
