Applies to: QuarkXPress 2018

Summary: QuarkXPress lets you specify the reading order by tagging items in the “Articles” palette. .

Solution:

The items in the PDF are read in the order they are tagged. This the enhanced version of “Reflow Tagging Palette” that you might have used in earlier versions of QuarkXPress, which has been replaced.
You can also use “Auto Tag Layout”, which is very useful for large documents. This is similar to “Add Pages to Reflow” option that you might have used in the earlier versions of QuarkXPress.
You may re-order the items in the palette, if required and can create multiple “Articles” to group “Components” for ease.
