The technology of the used machines and tools in printing technology and in the offset printing has reached the stage when, technologically, it is very difficult to raise the printing quality with the up to now used production materials, which the world market demands more and more [1, 2]. Because of that the producers of the printing materials and inks invest great means in the development of ...

Sea hares of the genus Aplysia rely on an array of behavioral and chemical defenses, including the release of ink and opaline, to protect themselves from predation. While many studies have demonstrated that ink and opaline are repellent to predators, very little is known about which components of these secretions are active against predators. Ink was previously shown to facilitate the escape of...

One of the most distinctive and defining features of coleoid cephalopods-squid, cuttlefish and octopus-is their inking behavior. Their ink, which is blackened by melanin, but also contains other constituents, has been used by humans in various ways for millennia. This review summarizes our current knowledge of cephalopod ink. Topics include: (1) the production of ink, including the functional o...

The development of high performance inkjet printers and inks is advancing rapidly. Manufacturers seem to introduce their new technology inks to the market on an almost daily basis. Chemists in ink laboratories are still fighting with the issue of combining a wide gamut of dye-based inks with the lightfast and weather resistance qualities of pigment-based inks into new-age ink formulations. Thre...

A novel roll-to-roll flexographic printing process for rechargeable zinc-based battery manufacturing was presented in this paper. Based on the fundamental operating mechanism of flexography, key criteria for developing functional flexographic printing inks were established, including composite ink rheology (steady-state viscosity and yield stress), ink wettability as well as ink dispersing qual...

This paper discusses various aspects of two ink aging methods that analyze ink volatile components, Sequential Extraction Technique (SET) and Solvent Loss Ratio Method (SLRM). Multiple ballpoint ink writings of various ages were tested by the SET and SLRM both before and after the pages bearing the writings were examined for indented writing impressions using an electrostatic detection apparatu...
