Quark has bought Silent, a German software developer, after failing to snap up rival Adobe Systems last week.
The publishing software company also announced a marketing agreement with Sun Microsystems.
Financial terms of the deal to acquire Silent, which specialises in advertisement management, production planning, and archiving applications, were not disclosed.
Quark also revealed a joint support and marketing agreement for two of its products, Digital Media System, and Quark Publishing System, on Sun's Solaris platform.
The announcements coincided with Adobe's unveiling of its high-end publishing system, K2, which is being trumpeted as a rival to Quark Xpress. Analysts have speculated that Quark's bid for Adobe was in response to the perceived threat of K2.
