Line Weights Change When Uploading or Sending PDFs via Email

[jayjay_2398]

Hello, I am trying to upload a pdf made in either indesign or illustrator. When i export or save as to pdf from these programs the lineweights appear as i want them to, but when i upload the pdf to google drive or send them via email the lineweights become extra thick. I have  been searching for fixes for this issue and have had no luck yet. 

I have attached the files (excpet the illustrator file because it would not upload) if someone could help that would be great. Thanks

I don't know if it's related, but Acrobat has the Enhance thin lines option:

It's enabled by default. Certain thin lines may become invisible if you uncheck this (which happens with your file, too).

Other PDF readers may treat such lines similarly without an option to disable this setting. Once again, not sure if that's the issue you experience.

And, as always, PDF viewers other than Genuine™ Acrobat may render documents according to different rules. This is particularly true for PDF viewers built into email clients, browsers and mobile devices, and is mostly true of the third-party viewers like Foxit. There's next to nothing you can do about this if you can't require your recipients to use Acrobat.

HI Thanks for the reply. Have tried that and unfortunately doesnt fix my problem. Even if i email myself the pdf and download and view it in adobe acrobat it changes somewhere along the way.

Can you ZIP / RAR and then email / share through GDrive? Maybe even with a password?

I've had a problem recently - on some project - that in DOCX files shared via OneDrive - some of the styles disappeared or their definition changed... Zipping them before upload fixed the problem.

Okay, so just to clarify —

• You create a PDF.
• It views fine in Acrobat.
• You email the PDF to yourself, and extract it from the email.
• The PDF now shows this line fault, in the same viewer.

...?

Are the file sizes the same before and after emailing? What email/client/platform are you mailing it with?
