Signals Notebook: Why are there visual differences between my experiment in the UI and the printed PDF?

Signals Notebook users can take advantage of the possibility of printing their experiments in PDF format. Nevertheless, the PDF does not always have the same visual representation as the user interface (UI). In case of visual differences between the experiment and the printed PDF, this is an expected behavior. PDFs should never be thought of as a 1:1 accurate representation of what is on the screen in the UI, since the objects must be resized according to the target PDF size.
