We propose a method for hiding patterns within printed images by making use of classical and of two daylight fluorescent magenta and yellow inks. Under the D65 illuminant we establish in the CIELAB space the gamut of a classical cmyk printer and the gamut of the same printer using a combination of classical inks with daylight fluorescent inks. These gamuts show that a significant part of the cl...

This article focuses on how gender, as a socially constructed phenomenon, has been integrated into development practice. It examines the notion of “development” as generated by an economic paradigm that renders the work of women invisible. Further, it critiques the different ways in which women have been incorporated into development policies and program. An examination of issues facing women i...

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

wileyonlinelibrary.com to authenticate are therefore important for the protection of brands and valuable documents such as bank notes, diplomas and certifi cates. Luminescent tags or labels are appreciated security elements for protecting authenticatable articles. One way to incorporate luminescent materials as luminescent security elements is to print them with luminescent inks. [ 2 ] Nowadays...

The purpose of this paper is to develop an innovative system which uses chipless RFID tags to protect sensitive paper/ polymer-based documents, such as intelligence agency reports, financial securities, envelopes, stamps, and banknotes. The significance of this project is vital as the expected outcome from this new system can be used to strengthen the security of important documents and banknot...

Cultural factors have long been known to influence the communication and success potential of competition in conducting international business. Cultural awareness shapes how business firms behave in cross-culturally reflected international markets. It is broadly recognized that cultural factors act as invisible barriers in international marketing communications. Understanding cultural differenc...

The use of four process inks (CMYK) is common practice in the graphic arts, and provides the foundation for many output device technologies. In commercial applications the number of inks are sometimes extended beyond the process inks depending on the customers’ requirements, and cost constraints. In inkjet printing extra inks have been used to both extend the color gamut, and/or improve the ima...

A review on applications of metal-based inkjet inks for printed electronics with a particular focus on inks containing metal nanoparticles, complexes and metallo-organic compounds. The review describes the preparation of such inks and obtaining conductive patterns by using various sintering methods: thermal, photonic, microwave, plasma, electrical, and chemically triggered. Various applications...
