Low- and High-res

This section details how fonts will be embedded. The default (“Subset fonts... less than 100%”) means that all the characters used in all the fonts used will be embedded in the resulting PDF (fig. 12.11). This can be done without infringing on the font licensing you agreed to when buying it, as fonts cannot be extracted from a PDF document.

High-res only

When using PDF/X1a, check there is a Transparency Flattener setting. This determines how any transparency effects or overlaps are translated. Generally, low-res converts them into vector information, which is efficient in terms of file size but may not print so well. High Resolution, the default setting for PDF/X1a (fig. 12.11), generally means that transparency is converted to pixels. Larger files, but better quality. This option cannot be changed in the Smallest File Size preset.

Security

PDF documents can be secured so that they can be read, but not printed; edited, or not; opened, or not. Each depends on a password, which you assign here. This may be needed in order to restrict the distribution of a low-res PDF but is rarely required for high-res.

Summary

This area details the settings you have just put in place and allows you to save it as a report.

At this stage, when all the settings are in place, you can save everything as a custom preset. Click on Save Preset in the lower left corner of the window, and enter a name.
