EFTA is the UK trade association for the flexographic industry and its annual awards event is now in its 30th year.
The judges recognised Schawk for the "outstanding quality" of its reprographics and for its contribution to a significant number of the winning entries on the night.
Matt Bennett, European managing director at Schawk, said: "We have worked extremely hard to deliver real industry excellence over the last few years and it's really fantastic to see this recognised."
In addition to picking up the award for reprographics, Schawk was also nominated for EFTA's 2010 Supplier of the Year award.
The awards ceremony was held on 24 March at the Royal Armouries, Leeds.
