Scribus

drawing the screentone over which the elements will be placed and define the sample pages. This characteristic allows you to save time not having to create the base page over and over again. Another way ot save time is to create personalized paragraph and line stiles (threads). The elements that you insert in the page (text boxes, images, tables, shapes, polygons, Bezier curves...) can be grouped to facilitate page editing and locked to prevent unwanted changes. With support for CMYK and ICC color administration, Scribus can save projects in PDF format without requiring help from another application. What's more, it also allows you to create PDF documents with editable controls (text boxes, check boxes, lists, etc.).
