Designing and exporting your PDF for online viewing is a different task than for print.

It's important to make sure that your output looks crisp and desirable across all devices and screen sizes while maintaining fast loading times.

Fortunately - the iPaper platform does most of the work for you!

This guide will show you how to design and export your PDF for optimal results with the iPaper platform.

Designing for the iPaper Platform

The iPaper platform will always show your publication as a spread (two pages facing each other).

This means you need to design and export your PDF files with that in mind.

Furthermore - when designing for online use, it's important to remember that your publication will be displayed on screens exclusively. This means there are some restrictions, regarding the format, different than those for printed publications.

Your font choice should be limited to sans-serif types.

The general font size should be easily readable on mobile, preferably without needing to zoom.

To achieve the best - readable - result, consider this article on font types for online use.

General tips and guidelines for format and layout

File Details

  • Maximum PDF file-size of 1 GB 
  • PDF is not "secured" or "restricted"

Images & Colours

  • Avoid hidden layers if not explicitly needed
    (e.g., No old text layers with other objects placed above)
  • Avoid complex vector images, as they can cause PDF conversion to fail

Fonts

  • If possible, embed all fonts in the PDF
  • Text should be intact & vector
  • No outlines or bitmaps
    (You should be able to highlight & copy the text on the PDF file)

Page sizing

  • Pages cropped to size, no visible cutting lines
  • A4 size (210x297mm) pages or 210x280mm will yield good results across devices. A square format (f.ex.  280x280mm) will utilize more screen space on desktop/laptop monitors but might not provide an equal experience on mobile devices in portrait mode.
  • Creating your InDesign document with Facing Pages and Portrait orientation will give you the optimal view and best results when working on your Flipbook.

Exporting your PDFs for the iPaper Platform

When you have finished up your design, you will need to export to PDF.

General

  • 1. Preset
    Even though you are about to export for online use, select the High-Quality Print preset.
  • 2. Compatibility
    Go for Acrobat 6 / PDF 1.5 compatibility
    ** iPaper does not support PDF 2.0 **
  • 3. Pages
    The iPaper platform will always display spreads (2 pages facing each other).
    This means you have to export your PDF as single pages for optimal results.
  • 4. Layers
    You should only export Visible & Printable Layers if you have a specific need for content in hidden layers (e.g., for Custom Link Import purposes)
  • 5. Interactive Elements
    The iPaper platform is not compatible with Interactive Elements, and they should not be included when exporting.
  • 6. Bookmarks & Hyperlinks
    If you created active links in InDesign, you can choose to export them, and then import them as an Index and active Links in your Flipbook.

Compression

To optimize your results across all screen sizes, we recommend exporting your PDF at 150 PPI.

Alternatively, you can input your PDF page dimensions in our DPI Calculator, to get the exact resolution you should export in:

Use settings as seen below:

Marks and Bleeds

Printer marks and Bleed should not be included in your export, as these options are for printing purposes only.

Save Preset...

You can save this as a Preset for use in future publications. Name it "iPaper" for easy access.

Export

All that remains now is to export your publication, and you will have yourself an iPaper optimized PDF.

Enjoy!
