Scribus

About

Scribus is a libre desktop publishing application positioned as a reliable, free tool that puts you in control of your data and, if you wish, the code itself. Its files are based on XML rather than binary formats, so they can be read and analyzed with a simple text editor, which makes damaged files easier to repair and lets you create Scribus files without the application.

For color work, Scribus ships with almost 200 color palettes, with around 400 more available for download as of version 1.6.0. It supports RGB, CMYK, LAB/HLC, spectral and spot colors, provides color management for controlling display and conversion, and can emulate various forms of color blindness to show how color choices affect people with color vision deficiencies.

For print production, Scribus was described as the first DTP program to support the PDF/X-3 specification, and as of version 1.6.0 it can also export to PDF/X-1a:2001 and PDF/X-4. It additionally offers non-print PDF output options such as presentations or forms.
