A practical guide

Draw attention to the relevant page area.

  1. Choose a PDF, target page positions and a highlight, rectangle or line.
  2. Set the mark's color, position, dimensions and available stroke settings.
  3. Create the copy and inspect the marked area and nearby content.

Try this example

Highlight a line on page 2 of a household instruction copy. Inspect the surrounding wording to ensure the mark points to the right line.
