Our import settings work well in almost all cases, but it is possible that complex PDFs are not imported correctly. Below you can find the issues that you can some across and the solutions to them.
- What to do if the color in my publication differs from the color in the original PDF?
- What to do if the text of my publication looks scrambled?
- What if I see small white lines in my images in the publication?
- What to do if I don’t want Publisher to import the links from PDF automatically?
For example, you get this result:
And your original PDF looks like that:
If you have this issue, the first thing to do is to check that you use the most recent version of FlippingBook Publisher. In the most recent versions of the software the issue should be fixed.
If you have the most recent version of FlippingBook Publisher, but still have this visual glitch, you can send us the PDF and we will be glad to fix it for you. You can forward your troublesome PDF to us using a file transfer service like Wetransfer.com and email it to firstname.lastname@example.org.
If you have the older version of FlippingBook Publisher or 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.
Note!Adobe Distiller destroys links in your PDF that is why to keep your links, please, follow the tip below.
Here is a way around that. The trick is to:
- Distill the PDF as usual.
- Then open the original PDF in Acrobat.
- Select all pages, then choose 'Replace pages'.
- Then select the distilled PDF.
This apparently keeps the links from the original PDF, but updates the pages themselves with the pages from the distilled PDF.
Please give it a try the next time you distill a PDF with links.
What to do if the text of my publication looks scrambled?
By default, we try to convert the text an SVG image. SVG images scales well under all circumstances and offer the highest quality. However, in very rare situations the text can become scrambled. For example, parts of the text may look bolder than in your original PDF. The first thing to do, is to Publish the publication as normal. The preview that you see in the software uses a very lightweight implementation of SVG, and even if there are slight distortions in the text when you view it in FlippingBook Publisher, the end result will often look perfectly fine in a real browser. Should the text in the end result still show up differently than in your PDF, then you can try to reconvert the text as PNG. You can reconvert the affected pages as follows:
- Go to the 'Pages' tab.
- Select the affected page(s). You can select multiple pages by keeping the Ctrl-button pressed down.
- Right-click on any pages. Select Import > Reconvert Page(s).
- Click on the small 'cogwheel' button to customize the import profile.
- Set the Substrates format to PNG.
- Uncheck the checkbox before 'Extract Text Layer'.
- Press 'OK' and then 'Start'.
The quality of the text will be slightly lower than extracting the text layer using the 'Auto' format, which creates the SVG image, but this is only visible upon close inspection and the result should look much better than with the scrambled font.
What if I see small white lines in my images in the publication?
If you see small white lines in your publications, then this is most likely due to the PDF version that you use. PDFs can be created in different versions, and older versions of this format did not support transparency and for layers. If you use these functions in your design-software and then generate the PDF using a PDF-version that doesn’t support these functions, then the images will get 'sliced up', to achieve a similar result. (If you inspect the PDF in detail, you will also notice these white lines - and during the conversion to a FlippingBook, the effect gets more pronounced).
To correct this, try to generate the PDF again in the software where you designed it, and then export it in PDF 1.6 (Acrobat 7.0 format). As a bare minimum, you should use PDF 1.4 (Acrobat 5.0) format.
What to do if I don’t want Publisher to import the links from PDF automatically?
If you have created links in your original PDF prior to importing it to FlippingBook Publisher then all the links will be extracted and made clickable inside the publication. If you don’t want this to happen, then you can change this as follows:
- Go to Edit menu and select Preferences
- Go to the Import tab
- Click on the cogwheel button for the Default PDF profile:
- Uncheck the Extract Links Checkbox.
If you import new pages then links will not automatically be extracted.
You can also use 'strict links matching'. This will import links that start with a protocol (like http:// or https://) or links like www.flippingbook.com. But links like flippingbook.com or online.flippingbook.com are not imported.
