As covered in the Enrichment Automation article, iPaper needs to find SKUs (Product IDs) in the PDF to be able to create shop links.
There are several ways to tag your PDF to include them:
Visible Product IDs
Visible product IDs, refers to having on-page IDs, which usually are next to the product.
This simply demands that you write the IDs as part of your design process and export with selectable text.
For best practice:
Use a simple font
Use the same font across SKUs
Keep the font size consistent across all SKUs
Keep SKUs text boxes clean from other text and vector elements.
To make sure you export with selectable text, follow the exporting guidelines here:
Hidden Product IDs
Hidden IDs, offer the most flexibility, as iPaper will read the IDs, but these won’t be visually present on the flipbook.
That way, during the design process, you and your team, can decide the exact position of the shop icons.
Important: If this is something you can easily implement, we highly suggest this option over the rest.
The following guide will show you the process of creating hidden layers in InDesign
Comment Product IDs
PDF comments offer the possibility of adding hidden product IDs when you don’t have access to the InDesign file, or for some reason, adding hidden layers in InDesign is not a possibility for you.
To do this, simply open your PDF in Acrobat Reader or Acrobat Pro:
Click Comment from the side panel
On the top menu bar, use a text box or the text tool to add your product IDs.
Important
Do not use the Sticky Note functionality, as the iPaper system can’t read nor extract text from this type of note.
