Pixelated Objects

Pixelated Objects

Problem/Question
Printing very small objects with PDF input files, the output might look pixelated, not smooth enough.

Solution/Work-Around
To improve the output quality for small objects you should change settings of the PostScript/PDF Parameters.

You can access the settings by
  1. Context menu (right click on the PDF file) > Renderer Options
  2. Top menu > Tools > Application Defaults > PostScript/PDF Parameters
  3. Top menu > Tools > Edit Presets > Composite Presets > Image Preset > + > PostScript/PDF Parameters


Automatic raster resolution reduction
For faster image processing, this is set to 300dpi by default.
-> Uncheck option or increase dpi to improve output quality.

Interpreter for PDF Rendering
For optimized PDF rendering of most jobs, this is set to default.
-> Switch to Legacy to change the PDF interpreter engine.

Deactivate Anti-Aliasing
For smooth font interpretation, Anti-Aliasing is turned on by default.
-> Use this option to sharpen small texts.  

    
Default settings vs. no raster resolution reduction

Side notes
  1. Always delete raster data before testing with a new setting (Top menu > Application Defaults > PostScript/PDF Interpreter > Temporary Raster Files > Empty Folder)
  2. Please be aware that the output quality is also depending on the printers native resolution.
