Description

It's sometimes needed to generate PDF files that can be reviewed on third party applications (i. e. Adobe® Acrobat Reader®) in an easy and reliable way. Overprints simulation are often a hassle. Below you'll find a few tips to achieve this with no need of enabling extra options as "overprint preview" or the like.

Procedure

  • The PDF will be generated by Automation Engine's Export to PDF File ticket and preferably should be of kind PDF 1.6 (PDF version in the Output tab), since behavior may be less consistent on this regard when using older PDF versions.

  • In order to simulate overprints the key is to rasterize the output PDF. You do this by checking the option Output as image, found in the Rasterize tab.

  • There are many compression options which will enable you to drastically reduce the file size if needed. These are the variable compression settings:
    • Rasterization resolution (in the Rasterize tab)
    • The whole Compression tab, paying special attention to Contones compression kind and its very own compression level, varying from Limited to Extreme.

      JPEG compression generally offers a very good balance between size and image quality.
  • Note that inks defined as technical will not be included in the rasterization. In some cases this needs to be bypassed, which can be done in two different ways:
    • Converting the output to CMYK: Use Color Management > Convert to: CMYK (in the Color Management tab)
    • If you prefer to keep the original separations, then add an Optimize PDF Separations step in your workflow before the Export to PDF File one. Then, in the Apply Ink Type option (Ink Properties tab), you can easily convert your technical ink to normal so this ink will also get rasterized:
