Reply To: Missing Text

Using character styles throughout is not the way to do things.

Use Paragraph Styles to style a paragraph, then apply a character style to individual words/letters within the paragraph using character styles.

<parastyle>Sample paragraph text and <bold>apply bold</bold>.</parastyle>

In the above, the main body of text is assigned a parastyle, and the “apply bold” would have a character style Bold.

Back to your issue.

It could be the text is set to overprint.

Hard to know why though – but something to check.
