Developers, answer me, please.
I used InDesign to make e-books (interactive PDF).
But every e-book was very heavy with 10 MB or more, even though I left the quality of the images at 72 or 96 DPI, and still using few images. It gets very heavy especially if you use dynamic links from Photoshop and Illustrator.
I tried everything, but I couldn't solve this problem. Is there any way to resolve this?
At Microsoft Publisher, Affinity Publisher and even Canva or Power Point it is much easier to have a light PDF with good quality images. I believe this is a defect in InDesign, the developers did not prioritize this part of exporting interactive PDF.
There is also another problem, and this is even worse.
The PDF made in InDesign when opened in Adobe Acrobat is always loading the images. As you zoom in or change the pages, images are always loaded.
I need to make a light e-book, with good image quality, and that the images are not loading all the time, and in InDesign the images are not static as if it were really a page printed on the screen, and that gives a file impression heavy .. Can you understand me?
I can only use InDesign again when I am able to resolve this, but I believe these problems are bugs.
It is not possible that even something like Canva is much more attractive to create a PDF than software for professionals such as InDesign, please check this out.

Problem in inDesign v15. Previous versión works fine

I use huge indesign files (wen name it A) inside a indesign file(we can name it B), is cool feature that optimice our workflow. After update, everythink looks working well but when we exporte print file in PDFx1a Format we experiment problems on RGB->CMYK conversión on images os "A"file, when we export from "B" file. But it work fine if we export on the original "A" source file. Some similar issues are detected, leaving space in white or low, strange white image file as described on attach file.

Not very sure if it is related with:

Thanks

A document exported to PDF from Indesign CC2020 fails to export the character U+06DD. There is a blank space instead. The only work around is to save as IDML and open and export with Indesign CC2019. CC2019 works just fine. Export choice (PDFx 3 or 1 or etc) does not matter. There is no difference between the two attached files. I exported the 01GEN CC2020.pdf first from Indesign CC2020 and you can see that the character is invisible (but still there). Then I saved the file to IDML, opened it with CC2019, and exported it without any edits. You can see the character clearly

In CC2019 and before, Indesign seemed to remember, in which folder it was exporting last. So when I was in Job A, it would offer me Folder A to begin with. When I was in Job B, it would offer mit Folder B to begin with.

In CC2020 (under 10.15.1) it seems Indesign shows the last folder I was woring in. So when I am in Job A an chose Folder A by hand, then close the job and open Job B, When exporting the file would be saved in folder A. Which is quite annoying to be honest. I also can't find any setting that would fix this (and if there are people out who feel the new way is way better: I would like to make a point for the old behaviour and maybe an option to choose between those two, since I solely need to export my pdfs in the folder my main job is located.

Is this behaviour intentional by adobe or could this be a mistake (and easily be fixed)?

Not sure if InDesign or Acrobat issue: Using 13.1. InDesign - Recently noticed that if I have text that flows to 2 lines and that has a hyperlink behind it, in Acrobat, the tags show the link as having two Link-OBJR, but they are the reverse of reading order. So if you tab the page, you go from 2nd line of text to first. So,

'Go to
the store'

tabs as if it is 'the store' 'go to'. The underlying link is fine--no issue there--it's the tab order and tag order (tag order perhaps then impacting screen readers/accessibility???).

This is in a single paragraph block, so not an issue of Article content out of order--the system is doing this. I think this is a recent bug (last 4-6 months?) --but whether in how InDesign feeds this to Acrobat or how Acrobat interprets, I don't know. I can manually fix in Acrobat but re-ordering the Link-OBJR tags, but it makes no sense that I should have to do so. Any idea what is going on?

PDF export constantly runs as background task with zero percent progress until I force quit InDesign, delete the temp recovery file, and delete the "zero bytes" PDF that InDesign failed to genereate. If I leave it and reexport once running InDesign again it happens again. I've found it takes deleting the recovery file (.idlk) and the PDF that has zero data at the location I tried exporting to. Once I do that it seems to work. My InDesign file is multiple pages (32). Smaller page counts and data files seem to work although my InDesign file isn't that large. Once I run through the aforementioned steps and export again the PDF is genereated within 15-20 secs.
I am running Mac OS Mojave 10.14.6

Not sure if this is a bug or intended but I don't think I have had this before as I have saved this file in the past for printing.

InDesign Vers. 14.0.3

White vector object (outlined text in InDesign not Linked/Placed) is changed to an RGB object when exported as a PDF from InDesign using PDF/X 2008 No Conversion Lab Ink Manager Values for Pantones are Lab for Spots & Convert all Pantones to CMYK.

Tried a test using the Save for Print default setting and it came out fine, as well as testing the Output Color Conversion set to Convert to Destination (Swop) preserve numbers which also did not produce the object as RGD. I tested using the paper colour as well as setting it as CMYK 0000 for the colour.

I have attached my PDF Export job options file. It is basically a standard PDX/X 2008 with the addition of bleed and crop settings. My colour settings are set to N/A general purpose.

If this was a placed object that was RGB white I could understand it not converting to CMYK if I didn't have convert to destination turned on but it is an InDesign Object that is coloured in InDesign using CMYK white.

Am I missing something?
