Flatten Transparencies

Flatten Transparencies

Flatten Transparencies is a REST API tool that renders and replaces all transparent objects in a PDF with opaque colors. This process increases RIP speed in a prepress workflow and supports conversion to other file formats.


  • Automate transparency flattening to streamline prepress workflows, reducing the need for manual adjustments.
  • Convert transparent objects to opaque colors to increase the speed of raster image processing (RIP), optimizing for print.
  • Flatten transparencies to ensure your PDFs are compatible with a wide range of printing systems and file formats.
  • Eliminate transparency issues and guarantee consistent visual document appearance across printing environments.
  • Ensure compatibility with older printing systems that do not support transparency for reliable print-ready PDFs.

Quality

The quality parameter lets you adjust the resolution level to use when flattening transparent objects in your PDF.


  • low quality is ideal for proofs that will be printed on black-and-white desktop printers and for documents that will be published on the web.
  • medium quality is best for desktop proofs and documents that will be printed on color printers.
  • high quality is ideal for final press outputs when high quality separations-based color proofs are needed.
