Fake InDesign Preflight error. Bevel and Emboss.

[behemotkot]

InDesign 2015.4 Release.

hi all,

Here's my problem, if I use the InDesign Bevel&Emboss FX on the stroke and on the object of the same rectangular, the preflight informs about the low resolution error (150 DPI). The resulting PDF is fine (all is in high res). Does anyone know the solution to avoid this false alarm in the InD Preflight?

Hi there,

Sorry about the delay. I am hopeful that the issue was fixed. In case it is still not solved I am sharing my observation after looking at your file.

I checked the file and didn't find any error in Preflight panel. I think you are using some custom preflight profile. Please open Preflight panel and click on basic preflight profile and let us know if it still gives you the error.

Thanks,

Shefali

Hi, Shefali.

Thanks for the Your answer. I look at the a. forum quite slowly, and the matter has reminded me recently. So, as you write, the basic profile does not show any errors, but it also does not check whether there are any low resolution objects in the indesign document. What I could expect is rather linked graphic files, and no object from indesign causes preflight errors.

Hi behemotkot ,

I did a preflight in Acrobat Pro DC on your provided PDF and found no error of low res images.

Tested with two preflight checks:

Resolution of bitmap images is between 0 and 100 ppi.

Resolution of bitmap images is between 100 and 300 ppi.

Also did a preflight with InDesign CC 2015.4 with a custom preflight profile that should check for images below 300 ppi effective resolution. And yes, I can see the issue now:

Three errors are showing up.

No idea why. I changed the current transparency flattening set to a high res custom one.

No change of the preflight result.

FWIW: InDesign CC 2019 14.0.1.209 is showing the same result with a custom preflight profile like that:

This error is a false-positive.

Why? It will depend on the transparency flattening setting you are using with PDF export how the transparency will be rendered to an exported PDF. Here an example where I used a highres transparency flattening preset with an PDF/X-4 export and the resulting image resolution is 1200 ppi:

My used custom flattening preset:

That setting used with PDF/X-4 export:

Thank You. It  is a false-positive error. I was just wondering if there is a way to outsmart this error in preflight. I am using an external preflight with an indesign server and one has to check everytime is it a real error. But I think that it is impossible to determine the resolution of the object in indesign so that it would affect preflight. Of course, when exporting a pdf flattener file, the preset is important. But the flattener settings for the preflight (indesign preflight)result have no effect.

Hi behemotkot ,

indeed this is a false-positive error.

Currently I see no way to trick InDesign's Preflight function.

The only way out would be a preflight of the exported PDF and come back to the InDesign layout if something is wrong with resolution after export.

Uwe
