SYSTEMS AND METHODS FOR FORMING RAISED MARKINGS ON SUBSTRATES FOR BRAILLE IDENTIFICATION AND SECURITY AND TO FACILITATE AUTOMATIC HANDLING OF THE SUBSTRATES |
摘要 |
Haptic or tactile features, which are generally not visually perceptible or reproducible, are applied at varying positions on a substrate according to a predetermined scheme. A plurality of raised image areas are specified for a group of substrates and raised marks are printed in only one raised image area for each substrate in a manner that is evenly distributed between the raised image areas for the group of substrates. The substrates will present a relatively uniform stack avoiding localized large pile heights when the substrates are stacked. A clear marking material is used to print the raised marks so as not to obscure underlying data printed on the substrate. The clear marking material may include a monomer that may become cross-linked in an exposure process to resist deinking of the substrate. The clear marking material may be mixed with a phosphorescing or fluorescing material as an additional security measure. |
