Question

Unlinked Image Mystery

I recently emailed a PDF created in InDesign to someone who uploaded it for print to 4-over, but when she received the printed postcards, one image (customer's logo) on it appears to be unlinked: clear spaces filled in white and jagged edges throughout/not a pixilated problem. The rest of the postcard is fine and clear including the other images used.  I rechecked the original file and the logo is linked and looks fine.  Is it possible for a PDF to suddenly "unlink" an image?  I packaged the file to her but she says she didn't open the InDesign file and re-export; she just uploaded the front and back files I had created and sent along.  Any ideas?  A friend said there may be some proprietary image issue going on.  The logo was fine, had many high resolution file formats to choose from. I used a PDF.  Any help is appreciated! I don't want this to happen again if it's something I can learn to avoid.

What filetype is the logo? What's the effective ppi if any, was it vector or raster?

 

Here's my guesstimation on what happened. 

 

The file has a transparent background.

And this happened

It's impossible to know without seeing the actual file that went to print and more information about filetypes and general setup.

If you care to share the indesign files/links and the print pdf we can investigate further.

 

I would guess the printers processed the file and flattened the transparency and caused the image to drop to low resolution during a transparency flattening issue.

Just a guess.

Okay thanks everyone.. This affected image was a PDF but not a vector. Yeah it wasn't a font issue, those were outlined .. Interesting about the flattening causing a lower resolution, I will pay attention to that. But this was drastic and it wasn't even that it was low res, it was like it was stair-step jagged and just that one image was affected if they did flatten it..  This was a major printhouse, 4-Over, so definitely not old fashioned technology (though they can be so stupid and their quality control is dubious to nonexistent). I haven't heard from them about it, only have talked to someone who sent it off for her customer. Here is the file and links, don't worry about the fonts, I'm only interested in the image of the logo...   Appreciate your help.

I haven't had a chance to look at the files, thank you for supplying

My idea was just a guess. 

Not only can transparency flatteners lower resolution they can also cause upaamplijg in certain conditions.

 

Interesting case you have. Thanks for sharing

I don't see any kind of a mystery here.

 

Do you have access to the file that has been sent to the print shop? 

 

If it looks OK - then the problem occurred when file has been processed. 

 

What kind of printing process - "old way" - printing press that required printing plates - or digital? 

 

If printing place have not sent proof for acceptance - nor checked first few copies with at least what's on screen - then it's their fault...

Hi @PrintServices123:

 

The image was missing from the PDF you created? Did you check the PDF prior to forwarding it to her? PDFs don't just unlink files.

 

InDesign can, when we move the assets from the folder InDesign is looking for, but this is prevented when you package a document, zip the new folder, send it on and have the new user unzip the folder. All of the linked content and fonts will be good to go.

Right that's what's so weird.  I packaged everything, all three images were linked.  The other two images came through fine, but that one doesn't looked linked to me in her photos.  We wonder if something else could be going on, like if there's some property attached to some files that disallows re-printing because of some proprietary issue or something. I mean, I could flatten, but want to know if this is a thing.

Proprietary info can be with fonts - rather not vectors or bitmaps - and even something like that would be - you would be first to get a warning - when exporting PDF from InDesign - so I can't understand from where is this idea... Have printing place suggested it - to cover their backsides?
