PasteBoard XT is a free plug-on that enables one to change the width and height of the pasteboard.
PasteBoard XT allows one to adjust by value as well as by percentage, giving a wider range of options than that within the QuarkXPress application.
Pasteboard XT settings can be accessed under the Markzware Menu under the Pasteboard item:
· Clicking on Pasteboard Settings brings up the Pasteboard Settings window where you can adjust the pasteboard size
· Clicking on Pasteboard XT Updates... fires up your default browser and takes you to the Pasteboard Updater web page.
