To avoid preflight errors, the Template Developer must ensure the document is compliant.

The PDF notes errors with Acrobat Version is not equal to 4.0

Please note that Adobe Acrobat 4.0 is an outdated version, and ALD direct to PDF does not support it. The minimum supported version is Acrobat 5.0.

If compatibility with Acrobat 4.0 is crucial, you will need to publish to PScript and adjust the Distiller settings accordingly.

In case Adobe Acrobat encounters issues with 'Transparent objects' or 'Blending color space,' please avoid using these features in the template.

Based on a quick Google search, it appears that preflight can report these issues and may offer an option to "flatten transparency." This process converts complex transparent elements into a single, rasterized image to prevent printing problems. Alternatively, flattening the image before incorporating it into the document might be effective. Testing will be necessary to confirm this.

I believe from a Case raised with PTC Technical Support that you noted these errors did not occur in ALD 12.1, but started with 12.2.

Over the years, PDFLib has undergone numerous updates and changes, introducing new features and resolving issues. In earlier versions, transparency errors might not have been detected, but the latest versions now correctly identify and report these errors and warnings. Therefore, it's not that version 12.1 was functioning correctly; rather, with the updates and improvements in PDFLib, versions 12.2 and 12.3 are now accurate.

I hope you find this information of help

Kind regards

Hi Alexia,

 

Thank you for your response. When we use the same images in Adobe products like InDesign, this error is not appearing. Also, earlier, we used to create ps from 3b2 and then convert it to PDF by using Acrobat Distiller. This distiller taken care of these issues. 

 

But, now we are forced to export PDF from ALD to retain the Accessibility features. For which we should depend only ALD and not Adobe or Pitstop.

 

Please advise. 

 

Thanks,

Siva
