Ever want to give your text in Adobe InDesign a highlighted appearance but not want to bother with creating a separate piece of artwork to overlay? It’s a simple effect to create, with the added benefit that it sticks with the text when it gets reflowed.
Adding a highlight effect in your InDesign document text doesn't require separate artwork
To create the effect, take note of the point size of your text (you’ll need to know that later). Now select the word(s) you want to highlight, click the fly-out menu of the Character Panel and choose Underline Options…. In the dialog box that pops-up, click the Underline On and Preview check boxes so you can view the effect in your document as you make adjustments.
To customize your highlight choose the line type from the drop-down menu, most likely you’ll want a solid line. Now choose a color (any color in your Color Panel) is available to use. You’ll want to do these steps first so you can see the results as you customize further.
Now adjust the Weight of the underline to be a few points thicker than the point size of your text – in the case of the sample image above, my text was 12pts, so I made the underline 14pts. Now adjust your Offset amount by a few negative points so that it overlaps your text – in my sample, -3 was just the right amount. Finally, click the Overprint check box to give it a more realistic effect (overprint will really show if your text is a lighter color). Now just hit OK button to apply the effect.
You could stop here, but you’ll notice that the highlight begins and ends exactly at the edges of the first and last letter of your highlighted word(s) – as you see in the top of the image at the right. While this isn’t that big of a deal, it’s not quite as realistic as it could be. To extend the highlight effect to just a tiny bit before and after the text as you see in the bottom half of the image, add a space before and after the word and reduce the Tracking amount of each space. I used -140 for the sample image to show how this adjustment affects the highlighting, but you may want to reduce the space even further to avoid unsightly gaps.
If you want to apply this effect to more text in your document, you may want to save the effect as a Character Style.
