Question

Mimetype change from application/vnd.adobe.illustrator to application/pdf if more then 10 artboards

Hi, there's a strange behavior regarding mimetype when saving an .ai file with more then 10 artboards.

 

Checking the mimetype using exiftool, if the .ai has more then 10 artboards, its mimetype is application/pdf. If there are fewer artboards, its mimetype is application/vnd.adobe.illustrator. This data is used later in an internal flow, so it is important that the mimetype is consistent.

 

The file is saved in a local folder, and it can be replicated by just creating a new document from scratch. I've tried to save it with or without 'toPdf' conversion but nothing changed.

AI version: 27.8

Replicated either on Mac and Window machine.

 

I've attached the screenshot of the log for either mimetype. Adding or removing the last artboard you could replicate the behavior.

 

It's a bug or some kind of internal limit regarding how AI file are saved? 

 

Thank you

    Hello @Davide5EC7,

     

    Sorry for the delayed response. I hope the problem is resolved by now. If not, kindly share more details, like the exact version of the OS/Illustrator, system config (CPU/GPU/Memory), and sample files (https://community.adobe.com/t5/illustrator-discussions/share-your-files-in-6-simple-steps/td-p/12967531), so we can investigate this further?

     

    Looking forward to hearing from you.

     

    Thanks,

    Anubhav

    Hi, the problem is already here.

    I’ve prepared some data, 10_artboard.ai, and 11_artboard.ai with 10 and 11 artboards inside, and the screenshot of the metadata of those 2 files. 

     

    https://shared-assets.adobe.com/link/5dd96ee4-9d0a-406f-4e85-d71163acf870 

     

    From your shell use the command

     

    exiftool <filename>

     

    And check the result. 

     

    10_artboard.ai (correct file)

    • File type: AI
    • File type Extension: ai
    • MIME Type: application/vsn.adobe.illustrator
    • XMP Toolkit: Adobe XMP Core 9.1
    • Format: application/pdf

     

    11_artboard.ai (incoherent metadata)

    • File type: PDF
    • File type Extension: pdf
    • MIME Type: application/pdf
    • PDF version: 1.6
    • XMP Toolkit: Adobe XMP Core 9.1
    • Format: Application/pdf

     

    Both of this are generated From Adobe Illustrator 27.8 (I've tried also on 27.7) and have the same error.

     

    I’ve tried it on Mac OS with the following configuration:

    • Montrey (12.2) with exiftool 12
    • Big Sur (11.4 ) with exiftool 11
    • Ventura (13.5) with exiftool 12.4

     

    We’ve done also a test on a Window machine, but the result was the same (I don’t have the machine specification)
