Our Laser Checks - Ultimate Security come in the highest level of security available. A hologram of an iconic eagle is embedded into the check. A Prismatic background creates a significant challenge for counterfeiters to duplicate. We offer four choices of Prismatic colors: Blue-Red-Blue and Gray-Burgundy-Gray, Green-Yellow-Green, or Burgundy-Blue-Burgundy. Overt florescent icons in the warning band, as well as covert florescent icons provide yet another layer of fraud protection, along with a survivable image. Our Laser Checks – Ultimate Security are printed on the finest security paper available and include a True Fourdrinier Watermark and Toner Adhesion. A Fourdrinier watermark is a watermark that is pressed into the paper at the mill and is visible from either side when held to the light. This dual tone watermark provides instant authenticity of the document and is virtually impossible to replicate copy or scan. Laser Checks – Ultimate Security are manufactured with a Thermochromatic ink with a keyhole icon. The Thermochromatic keyhole icon is printed with Thermochromatic (heat sensitive) ink the icon will disappear when heat of 85 degree or above is applied and reappear when cooled. Check may be verified by rubbing or breathing on the icon for instant check authentication. Color copiers cannot replicate Thermochromatic ink and this adds to fraud protection. Fraud Protection is the most important aspects of our printed checks. Our checks easily surpass ordinary standards as defined by the Uniform Commercial Code and have been determined in compliance with Check 21 and ANSI X9.7 standards.
