Indesign cropping leaves hidden text objects in a PDF, need to view in "wireframe" mode?

Here's a weird one. It seems cropping an image in Indesign leaves artifacts sometimes.

I'm having trouble with uploading to Amazon KDP - their system is saying there's text too close to the margin. But it's totally invisible in the PDF. But their system catches it.

Attached is the wireframe from Amazon support showing hidden graphics in a wireframe view. How do you do wireframe view?

Also, attached is the warning from their book review system - it's catching hidden text.

I've also attached the Indesign screencap of the page with the graphic clearly cropped.

It seems Indesign is hiding the text/graphics but it's actually still inside the PDF somehow.

How can one see the Wireframe mode? Adobe Acrobat, Reader, Indesign? This would be helpful in the future to know to avoid this weird problem.

Hi @elellilrah ,

about a wireframe view on a PDF:

There are tools for Acrobat Pro that provide a wireframe view like Enfocus Pitstop Pro.

Great, thank you. I saw that software. If I were a full-time production house, I'd get it but @ $32/mo.

I'll just be aware that anything I "crop" from Illustrator in Indesign isn't really a crop but a mask leaving crumbs in the PDF.

my understanding is the following (i'm sure others will correct me if I'm wrong):

you can't truly crop an imported non-raster page (that is a page that contains vector objects, including fonts). just like you can't truly "crop" a PDF page (as you already mentioned), even in Acrobat (unless it consists of raster images only). you can only mask such pages. i assume it's just too complex to "slice" multitude of vector objects, including text. how, for example, would you slice live text that's not converted to outlines?

now, evidently you could achieve a real crop when you exported the artboard from Illustrator. i assume Illustrator is more sophisticated when dealing with its own files. still, if your artboard boundaries crop live text in Illustrator it will also only be masked in PDF.

in Acrobat, if you cropped your page in Acrobat itself, you can try to reveal masked areas via the Set Page Boxes feature (Cmd-Shift-P).

The only way I figured out how to do it was to crop the artboard in Illustrator only for the area of interest, then export the artboard to a PDF. That way Illustrator did the cutting and I still had a vector image.

KDP suggested converting to raster but the fine lines of the map looked terrible. So, I went with the cropped PDF from Illustrator and it worked as needed.

Good to know about the "fake" cropping in Indesign. You're right - how could ID really "crop" anything like that.

Sorry for butting in - and maybe and probably not the answer - but wondering does the setting in exporting to PDF of Clip Images to Frames does not have any effect?

Once I took the maps I created in Indesign, cropped the artboard down to the area of interest, exported that portion of the AI file to a PDF, and re-imported into Indesign, the file would pass the check.

Why does Indesign not actually truly "crop" the AI file but leaves a hidden pile of crumbs?

KDP is... maddening. "Arbitrary and opaque" is just the beginning.

Be glad you found a fix without having to rely on any useful return data. They aren't much good at providing it.

But it's not news that graphics within PDFs are often only masked, not cropped. It's a dirty little secret that docs cropped in Acrobat to hide info can often be retrieved whole. And of course, all that data bulk is retained as well.

Use processes that actually crop images, especially AI and PDF, for all these reasons.

Wow that's really good to know things are masked over not truly cropped away. Will be more careful for sure. Don't want to leave something I don't want getting out.
