Israeli startup RealTimeImage has entered into a partnership with German print media solutions giant Heidelberg, to co-develop Internet-based proofing solutions for the print industry.

The agreement gives Heidelberg the opportunity to invest in the Or Yehuda-based company, according to the terms of a financing rounds held last year.

RealTimeImage, which maintains headquarters in San Bruno, California, expects its sales to increase 50% this year and is reportedly gearing up for a Wall Street IPO, when the primary market recovers. The company refused to comment.

The companies first announced their partnership at the Print01 expo in Chicago, in September. The first generation of their joint technology, to be called HDPROOF, was presented at Heidelberg's booth at the expo. It is slated for release in the fourth quarter.
