Abstract

The present invention provides a process for manufacturing a security feature for securing a value document, wherein said security feature exhibits a blue color upon viewing in transmitted light and a metallic yellow color upon viewing in Incident light. The manufacturing process comprises the following steps: a) printing a specific UV-Vis radiation curable ink on a transparent or partially transparent region of a substrate of a value document; b) heating the ink layer obtained at step a) at a temperature of about 55° C. to about 100° C. for at least one second so that the ink layer exhibits a metallic yellow color upon viewing in incident light; and c) UV-Vis curing the ink layer obtained at step b) to form the security feature. The manufacturing process according to the present invention enables the expedient production of security features exhibiting a blue color upon viewing in transmitted light and a metallic yellow color upon viewing in incident light and is particularly useful for industrial printing of value documents.

The present invention proposes a thermal inkjet printhead, as well as a printing assembly and printing apparatus comprising the same. The thermal inkjet printhead of the present invention comprises: a substrate; a nozzle layer, including a plurality of nozzles formed therethrough; a plurality of ink ejection chambers corresponding to the plurality of nozzles; a plurality of heater resistors formed on the substrate and corresponding to the plurality of ink ejection chambers, each of the heater resistors being located in a different one of the ink ejection chambers so that ink drop ejection through each of the nozzles is caused by heating of one of the heater resistors that is located in the corresponding ink ejection chamber; a plurality of separated cavitation islands formed on and corresponding to the plurality of heater resistors, each of the cavitation islands covering a different one of the heater resistors; and a dielectric layer interposed between the heater resistors and the cavitation islands. Using the present invention can help to enhance and substantially improve the printhead reliability, increasing in turn the yield of the manufacturing process.
