Applied DNA Sciences Enters Printing Ink Markets, Signs Agreement with Printcolor Screen Ltd., Switzerland.

STONY BROOK, N.Y. -- Applied DNA Sciences, Inc. (OTC Bulletin Board: APDN), a provider of DNA-based security solutions, today announced that it has entered into an Agreement with Printcolor Screen Ltd. (Printcolor), under which Printcolor will become a reseller of APDN's SigNature DNA Markers. Printcolor, a printing ink company located in Berikon, Switzerland, provides a wide variety of printing inks to its customers throughout the world. Printcolor has established itself as a market leader in providing its customers with innovative and technologically advanced solutions for screen, pad, flexographic and digital inks. Working together, APDN and Printcolor hope to harness the quality of Printcolor inks together with the flexibility and affordability of APDN's proprietary SigNature DNA Markers to slash counterfeiting and diversion losses of Printcolor customers.

The terms of this agreement provide for Printcolor to act as an authorized reseller of SigNature DNA Markers and permits Printcolor to embed APDN SigNature DNA Markers on all Printcolor products. Printcolor agreed to exclusively use APDN SigNature DNA Markers in its products and to market these products to its current and future customers. APDN agreed to provide Printcolor with sufficient quantities of SigNature DNA Markers to fulfill its customers needs on a non-exclusive basis, allowing APDN the opportunity to work with other printing ink companies in the future. APDN will not offer products to Printcolor customers except through Printcolor. In addition to adding SigNature DNA Markers to existing Printcolor products, APDN and Printcolor will work together to develop new products for clients as needed. This Agreement is for an initial three year period with automatic annual renewals thereafter.

As commerce transcends national borders and electronic boundaries, businesses are becoming increasingly concerned about the security of their products and brands and the protection of their customers. Governments too are anxious about lost taxes and tariffs due to smuggling and counterfeit products, as well as more sophisticated counterfeiting of printed products such as currencies, passports, bonds and other financial instruments. Counterfeiting, theft and diversion have an enormous impact on the global economy. The World Customs Organization and Interpol estimate that annual global trade in illegitimate goods was approximately $600 billion in 2004. Counterfeiting also presents a significant safety issue, especially for pharmaceuticals and foods and beverages that may come from a wide variety of sources.

"Printcolor prides itself on providing specialized and specific solutions in ink technology to each and every one of its customers and we are continually striving to increase our know-how and make the most of our resources. Partnering with Applied DNA Sciences is a perfect example of how we work with outside companies to continually bring the finest in ink technology and new innovations to our customers. The partnership between both companies completes the spectraCRYPT[TM] program of unique and forensic features for the brand protection and security market," commented Dieter Hermann, CEO of Printcolor.

"We are pleased to announce the completion of our fourth marketing or reseller agreement in the first half of 2007," stated Dr. James Hayward CEO of APDN. "The printing ink market is an important market in which to utilize SigNature DNA Markers and working with Printcolor, we can offer a low cost, high technology solution to the problems of counterfeiting and diversion faced by Printcolor customers."
