Abstract: The invention relates to a multiple pass printing process for generating MICR-readable indicia using a MICR ink-jet ink composition with a magnetic pigment loading less than that needed to generate the nominal signal level according to the ANSI standard with single pass printing, and to a printed substrate, prepared by the process, which bears MICR-readable indicia having at least two layers of the MICR ink-jet ink composition and which demonstrates a MICR signal level of greater than or equal to the nominal signal value according to the ANSI standard.

Abstract: A non-aqueous ink jet ink for printing lithographic printing plates. The formulation provides for ink jet printing using a solvent based ink in a drop on demand printer. The ink exhibits excellent physical properties and good stability over a range of times and temperatures.

Abstract: The invention relates to an ink-jet ink composition suitable for use in secondary transfer processes wherein the ink-jet ink composition contains a pre-dispersion containing at least a sublimation colorant combined with an ink-jet ink containing at least a non-sublimable colorant. Upon printing, a monochrome intermediate transfer substrate is created. From this monochrome substrate, a multi-color image can be transferred to a permanent substrate with the application of heat and pressure. The monochrome intermediate transfer image is created by the non-sublimable colorant upon printing. The multi-color permanent image is generated as elevated temperatures and pressure of the transfer process cause the sublimation colorant to sublime and bond to the permanent substrate.

Abstract: A process for preparing an aqueous ink-jet ink composition for MICR applications is provided comprising preparing a metal oxide pre-dispersion combined with an aqueous ink-jet ink composition, wherein the metal oxide pre-dispersion contains metal oxide pigment or particles of a very small particle size, about 0.5&mgr; or less, and exhibiting high remanence of at least 20 emu/g. The metal oxide particles may be coated with a hydrophilic coating, and the pre-dispersion may contain at least one surfactant to aid in the dispersion of the metal oxide particles. Special processing involving the use of conventional and non-conventional grinding techniques and various filtration techniques enhance the compatibility of the MICR ink-jet ink with the ink-jet equipment, resulting in superior ink life and print quality.

Abstract: A system to protect documents such as negotiable instruments, title instruments and identification documents from illegal copying by color copiers and alteration such as amount or signature particularly computer printout documents comprising preprinting a "VOID" pattern over the amount and/or signature area of the document in solvent insoluble or color change ink. The VOID is printed with a camouflage pattern overcoating. The camouflage pattern overcoating may be a pattern or solid coating. It may be a coating on the undersurface of the Mylar film overlay of the "VOID". Thereafter the disclosure contemplates adhering the Mylar film to the document to be protected over the amount and/or signature area with cold pressure. Color copying by machine is prevented by the use of colors in the inks which are below the critical density of the copier, so as to verify the authenticity of a document and prevent fraudulent use of a copy.
