The goal of this partnership is to create a secure, difficult to counterfeit high throughput technology that meets emerging market needs identified by the industry partner to integrate laser printed colour pictures into picture ID documents. Colour picture IDs on official documents (passports, driving license, etc.) are currently produced using ink-based printing. This approach produces a surface image that can be altered or counterfeited. Alterations include mechanical or chemical erasure, reprinting, or delamination attacks, while counterfeiting involves reproduction of the document using substitute materials and processes. To improve the safety of picture ID documents, pictures should be located within the bulk of the materials (usually polymers). A solution currently used commercially is to laser-engrave (in this case burn) polymeric materials in the bulk to create dark areas while the untouched material remains white. This results in a black and white picture ID. While this technology improves the security of the picture ID, there is now a growing need to obtain colour picture IDs, like those created with inks, but within the material. The University of Ottawa is partnering with the Canadian Bank Note (CBN) to create a laser printing solution that will result in a secure, customizable, high resolution colour picture within the bulk of polymers used in picture ID documents.

该合作伙伴关系的目标是创建一种安全、难以伪造的高吞吐量技术，以满足行业合作伙伴确定的新兴市场需求，将激光打印的彩色图片集成到图片ID文档中。官方文件（护照、驾驶执照等）上的彩色照片身份证目前使用基于油墨的印刷生产。这种方法产生的表面图像可以被更改或伪造。篡改包括机械或化学擦除、重印或分层攻击，而伪造涉及使用替代材料和工艺复制文档。为了提高图片ID文件的安全性，图片应位于材料（通常是聚合物）的主体内。目前商业上使用的解决方案是在本体中激光雕刻（在这种情况下燃烧）聚合物材料以产生暗区，而未接触的材料保持白色。这导致了黑色和白色图片ID。虽然该技术提高了图片ID的安全性，但现在越来越需要获得彩色图片ID，就像用墨水创建的那些，但在材料内。渥太华大学正在与加拿大钞票（CBN）合作，创建一个激光打印解决方案，该解决方案将在图片ID文档中使用的大量聚合物中产生安全，可定制，高分辨率的彩色图片。
