Our Laser Checks – 3 To A Page come in granite, linen and parchment background types. You may select available colors from the dropdown menu for each paper check background type. These laser check granite, linen and parchment colored backgrounds are difficult to duplicate, and the warning bands alert the handler that the check contains security features. Our checks are printed 3 To A Page on 25 lb toner bond paper, which is MICR-OCR compatible. Our checks are printed with toner adhesion with an artificial watermark and an invisible florescent logo. Our Laser Checks – 3 To a Page backgrounds are manufactured with a Thermochromatic ink security 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.
