Our import settings work well in almost all cases, but it is possible that complex PDFs are not imported correctly. For example, you get this result:
However your original PDF looks like that:
In such cases we will be happy to help you to correct this. You can send us the PDF and we will be glad to fix it for you. You can send your troublesome PDF to us using a file transfer service like Wetransfer.com and email it to firstname.lastname@example.org.
If you want to fix this yourself, you can try to export it again from the application that you created the PDF in as PDF 1.4 (Acrobat 5.0). This flattens the layers in the PDF, which in combination with transparency often cause these issues. If you have Adobe Acrobat Pro, then you can also achieve the same result by saving it as Optimized PDF, and then change the compatibility settings to “Acrobat 5.0 or later”
If that doesn’t help, you can try to ‘distill’ your publication in Adobe Acrobat Pro. This is done as follows:
- Open the PDF in Adobe Acrobat Pro and click on File - Save As - Other - PostScript. Choose a new name.
- After the PostScript file is generated, double click on it. That will open a window of Adobe Distiller, which generates a new PDF file.
- Please make sure the default setting is chosen for High Quality Print.
- Wait until the progress bar shows that conversion is completed and then try to import the generated PDF in FlippingBook.
