Use “Photoshop PDF” to Keep Text & Vectors

If you import a native Photoshop document (PSD) into QuarkXPress, the type and shape (vector) layers in the Photoshop document will be rasterized when you print or export it to PDF.

To maintain the crisp edges of the type and vectors contained in the Photoshop document, save it in Photoshop PDF format and then import that PDF into InDesign or QuarkXPress instead.

The vector data will then be passed along to the printer, as well as included it when you export the document to PDF format.
