Reverse Engineering Conversion

Conday · 09-15-2021, 10:36 PM

I apologize if this has been asked and answered before. I used calibre to convert an epub file so I could print it out through Adobe acrobat DC. It went well, and I’m now trying to print out another volume in the same way. The problem is I don’t remember exactly what steps I used, so the new volume looks significantly different in terms of font, margins, pictures wrapping around the end of a page, etc. My question: is there a way to use the pdf version I life to determine the conversion steps used to achieve it? Then I could simply perform those same steps in vol. 5. Thank you for the help

Conversion options are saved, so simply open the conversion dialog for the previously converted book and copy the relevant settings.

Thank you for the quick reply. Where exactly is the conversion dialog? The other odd thing is that my previous book was saved under users without the name of the author in the files title, while any new conversions I’ve tried are saved elsewhere and WITH the authors name in the file. And it’s not like I changed a bunch of settings when I did the first one. Honestly I don’t remember doing any.

And when I open it with Adobe and check the fonts, it lists them as Cambria Math, SegoeUISymbol, and Times New Roman, which certainly aren't the default fonts for conversion. The only thing I can think of is that Times New Roman is the default font for my Microsoft Word. But how that gets into the pdf conversion I'm not sure. It took me so long to figure out how to download the ebook, use Obok DeDRM, then get it to a place i could print, I honestly can't remember what i did to get the pdf version at all.

The issue may be the settings in the Adobe Acrobat printer driver used to print the EPUB to PDF.

That's exactly what it was, thank you! I opened the epub through calibre, then right-clicked and printed to pdf; I didn't actually use the conversion option for that file.

Printing in the calibre viewer just does a PDF conversion under the hood, with default settings.
