ITW Security Division has developed a new generation of Unichroma dye diffusion thermal transfer (D2T2) ribbons for Matica Technologies' S7000 high volume card issuance platform, enabling it to deliver full colour image printing across the latest polycarbonate and hybrid card substrates.The firm has said the Matica S7000 is the ultimate in a-la-carte central issuance systems and can be configured to perfectly match the most demanding card issuance programs, while at the same time easily supporting any upgrades that may be required in the future for increased performance or additional functionalities.Integral to many government card projects is the requirement to add the cardholder's image, however printing on some of the latest card substrates can present a technical challenge to standard D2T2 printing.ITW Security's Unichroma ribbon technology acts as a colour primer to both improve the appearance of D2T2 printing on some plastics and enabling its use on others, such as PC, without requiring special, expensive card stocks. Unichroma is supplied on the same thin PET carrier ribbon as D2T2 dyes and applied directly to the surface of the card as a clear, colourless, dry coating, by the S7000 thermal print head module. It ensures low-cost colour personalisation, due to its ability to be selectively applied to the card's surface only where colours are needed, leaving the remainder of the card area unmodified. This minimises the cost per card and enables use with a wide selection of over-laminates to achieve the desired performance characteristics.ITW Security Division worked extremely closely with Matica to integrate the Unichroma D2T2 ribbon for the S7000 thermal print module. Commenting on the successful development with Matica Bob Carey, ITW Security Division's Business Unit Manager said, "Throughout the design process, both companies worked hard to successfully integrate the Unichroma ribbon technology within the S7000 thermal print module and deliver the capability to add a full colour image to the ID card. PC or hybrid cards are growing in volume and with this latest personalisation option for driving licences or government ID cards, their security can be dramatically increased".Ricard Ferrer, Global Marketing Director at Matica Technologies concluded, "We are extremely happy with the Unichroma ribbon from ITW Security Division which now enables the S7000 to print colour photographs combined with laser engraved personalisation, optimizing both ID card security and ease of authentication for our customers. It is an excellent example of ITW Security & Matica working together and enabling a novel solution to help address this market issue".
