Improvement of light fastness of water‐based printing inks with addition of glycerol derivative containing thiol groups

The aim of this work was to study the influence of a glycerol derivative with thiol groups, 3,6‐dithia‐1,8‐octanediol (DTO), on light fastness of prints overprinted with water‐based flexographic printing inks. Laboratory printing was performed on various plastic films (BOPP and PE). The effect of a small amount of DTO on printing ink colour was examined by studying the optical density of a full tone area, relative printing contrast and the colour values (CIELAB), and the total colour difference, . Artificial ageing was applied in order to investigate DTO influence on colourfastness of CMY printing inks. Densitometry and spectrophotometric parameters were measured during artificial ageing by irradiation. Additionally, FTIR spectroscopy was used to observe the changes in ink film on printing bases before and after ageing. The print quality of investigated prints is widely discussed. In general, DTO addition influenced the printability of the plastic film and the optical density of a full tone area with an acceptable total colour difference . Furthermore, printing inks with added DTO exhibited higher optical density and smaller changes of during artificial ageing. Moreover, the FTIR spectra of printing ink films with added DTO after ageing did not exhibit any perceptible changes in contrast with the original printing ink.

Fabrication of ultra-fine nanostructures using edge transfer printing

The exploration of new methods and techniques for application in diverse fields, such as photonics, microfluidics, biotechnology and flexible electronics is of increasing scientific and technical interest for multiple uses over distance of 10-100 nm. This article discusses edge transfer printing--a series of unconventional methods derived from soft lithography for nanofabrication. It possesses the advantages of easy fabrication, low-cost and great serviceability. In this paper, we show how to produce exposed edges and use various materials for edge transfer printing, while nanoskiving, nanotransfer edge printing and tunable cracking for nanogaps are introduced. Besides this, different functional materials, such as metals, inorganic semiconductors and polymers, as well as localised heating and charge patterning, are described here as unconventional "inks" for printing. Edge transfer printing, which can effectively produce sub-100 nm scale ultra-fine structures, has broad applications, including metallic nanowires as nanoelectrodes, semiconductor nanowires for chemical sensors, heterostructures of organic semiconductors, plasmonic devices and so forth.
