The Print Preview
From Scribus Documentation Project
A simple use of Print Preview might be to just get a sense of how your document looks without all the non-printing objects visible, such as Margins, Guides, and frame borders. One can of course do that by deselecting these in the View menu, yet with Print Preview one can go back and forth with one click.
Print Preview initially generates the same process as printing, in which your Document is sent to the Preflight Verifier and any errors or problems identified, according to your settings in Preferences or the Document Setup. If you have no problems or click "Ignore", then the Document is processed as if being printed, but only a screen display is generated, with some limited ability to change the page display size.
There are some other view adjustments, the only one perhaps needing some explanation is the "Display Transparency" checkbox, which will remind you that what Scribus actually generates are instructions for printing on some medium, so now you see your frames and other objects, with their associated backgrounds if they are not also transparent. Partial transparency will also be shown.
To see how it works, look at the screenshot below. It shows a Print Preview of our cover page from the Quick Start Guide. You may remember that the color we chose for the text "REMBRANDT" was white. Technically, "white" in CMYK has the values C: 0, M: 0, Y: 0, K: 0. In other words, it doesn't exist, and that's why we don't see anything of the white text in this preview. Why is this information useful? Because you can learn that if you print to anything but white paper, you'll need a spot color to actually print the color white
Among the settings is a chance to view your Document in CMYK, and you can choose to view individual or collected color separations in case this is important before you send your PDF to your printer (local or commercial). If your document contains spot colors, Scribus will list each color with its name below the Separation Names.
If you are satisfied, you can either close or print.
