Micro printing is used to prevent copying. This security feature is usually a signature line or border made up of words so small they give the appearance of a line. If scanned or copied the lettering fills in making the words unreadable. The second image to the right is the signature line contained in the circle in the first image. |

Bleed Through MICR Numbering contains special dyes in the MICR ribbon that bleed through the paper making the number visible on the back side of the form. To alter a number, it would have to be completely removed. |

Foil stamping will resist photocopying when high metallic foils are used, such as gold or silver, usually causing the copy to appear mostly black. Foil stamping requires the use of a heated die to fuse metallic or color pigmented foil to the paper. Also a generic two dimensional diffractional holographic foil can be used that contains random pictures or messages that vary with the change in viewing angle and light.

Prismatic printing, also known as split fountain printing is the process of blending two or more ink colors from a single print unit. Because one tower and one plate are used, the ink is allowed to flow down to the printed image creating an effect that resembles looking through a prism. The blending of inks causes problems for color copiers to duplicate the original. For this feature to be effective, your staff authenticating documents must be trained to identify the original document. Though difficult to authenticate, it should deter criminals to look for easier targets. |

This "Void" Pantograph features patented technology that utilizes lines of varied lengths and angles. The background and warning words are printed with the same line frequency as the scan line of the copier or scanner. The letters in the "Void" show on the copy because they are printed with a different line angle than the scanning device. |

The technology used to create the void pantographs shown here was designed to defeat color copiers and scanner equipment. Standard Register owns the patent on the original feature. As you can see from the first pantograph, even adding "noise" and various blurring techniques the "void" shows clearly.
