Hello,
In Indesign, if I open a multipage PDF, is it possible to remove its background (by using Indesign only) ?
In that case, I would like to remove this yellow background :

Image processing is the way to go, but here you might fake it using SCREEN blending mode on a BLACK background.
Simple demo script:
(function( orig, dup,g)
//----------------------------------
// Assuming a simple image container is selected on the page.
{
// 1. Basic enhancer.
(orig=app.selection[0]).properties =
{
strokeColor: "Black",
transparencySettings: {blendingSettings:{blendMode:+BlendMode.SCREEN}},
};
with( dup=orig.duplicate() )
{
...

You'll need Photoshop for that.

No.

As said, not in InDesign, but it should be realtively easy to do in Photoshop with either a levels or threshhold adjustment layer.

You mean posted by the OP in Acrobat forum - using exactly the same image?

Yes, the OP posted similar questions in the Photoshop, Acrobat & InDesign forums using the same image.
Interesting solution using layers & Effects, good example of thinking outside the box.

Thanks.
But I'm not sure if it will print correctly... Acrobat is able to display it - but PS CS6 64bit - can't raster it correctly...

If it can display correctly in Acrobat, it should print correctly, you may need to flatten the pdf first.

In fact, I have not Photoshop to do the job. Personally, I would prefer to do it completely in Acrobat (as the score is in a PDF), but I was wondering if InDesign could do it. It seems that it is not possible in Indesign

Are there layers in the pdf?
If so and the background layer is the yellow then you can turn off that layer in the pdf in InDesign.

Unfortunately, there is no layers in the PDF :

The link to the other thread explains how to remove it. And I see you don't have Photoshop. But there other free image editors that can also do this, like Gimp or online photo editors.
And I'm sure you will find many tutorials online to remove the background.
InDesign does have image editing capabilities. It's a layout and design software to incorporate elements into a page layout and it's up to the user to ensure images prepared correctly and inserted to the layout for the purpose.

So you have InDesign but not the whole Adobe CC?

It is possible to do it in InDesign:
No external software has been used.

Attached is IDML file and PDF - INDD is 61MB - as Image is embedded.
There are multiple copies of the original image - placed on top of each other:
The bottom Rectangle - is filled with "[Black]" color and Transparency set as:
Each copy of the image - Transparency:

Ah, that is HIDING the colour background, not removing it 😉

Hiding / removing - who cares, as long as it's "not visible" 😉

The biggest bonus - no need to waste time on editing AND you keep the original intact - just place, apply ObjectStyle, duplicate few times, done - easy to automate with my tool - either on a current selection or multiple links already placed or when placing from a folder.

That's certainly clever, but the results from converting to grayscale and adding a levels layer in Photoshop are far superior, in my opinion. You've lost a fair number of edge pixels and hairline segments, and it's still in color so printing is gioing to be less crisp.

Yes, you are right, doing it - in Photoshop or something like that - is the only correct way.

To be honest, my first attempt was only partially successful - I've only stacked images - and it looked good - but then I've turned on overprint preview - and zonk - back to brown.
Then, I've added this black rectangle at the bottom - it worked.
Maybe my laptop is too slow, but when I open this PDF in Acrobat - I can see "layering" - images being added and color changing.
Then there is a problem in Photoshop - it can't raster it correctly... In CMYK it's like there is only one image so no effect at all - and in RGB it's still brownish - or vice versa.
So who knows how it will print - on a desktop printer and what RIP will produce ...

Sorry for no reply.
I think @Marc Autret's reply is spot on and you should go with it.
