An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. Finally, the substrate acts as a receiver of the inks and forms the images. Ink setting on the substrate is a compl...

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...

A spectral colour prediction model is proposed and applied to an ink jet printer. We limit the field of investigation to transparent inks printed on a transparent substrate. The proposed method is based on the computation of the transmittance spectra of colour primaries applying Beer’s law, and on the calculation of their respective surface coverage using a high resolution grid. The proposed pr...

High viscosity ink is a potential solution for the improvement of current 3D ink jetting technology. In this study, experiments are carried out to study a series of inks with differing viscosities jetted with PicoDot jet valves under different process parameters of temperature and pressure. Results show that a wide range of ink materials from low viscosity (water like materials) to very high vi...

Additive-Free Inks Additive-free dry-only inks can enable functional printing and high-throughput fabrication of elec-tronics at room temperature, but their design proves challenging. In article number 2103660, Jakob Heier co-workers show how interflake van der Waals interactions in 2D materials be used to replace the roles conventional additives for formulation additive-free inks.

is compatible with conventional device manufacturing processes8; doping processes that can assure stable, high electrical conductivity over long periods9; a method to improve the environmental stability of graphene electrodes against moisture and chemicals in the air10; and a method to decrease the contact resistance between electrodes and active materials11. One issue, in particular, with CVDg...

An analytical procedure for examination of fountain pen and ballpoint pen inks was developed, using the PrinCe 550 capillary electrophoresis system with spectrophotometric detection. Samples were taken from ink lines in the form of paper microdots of 0.8 mm diameter. The ink sample was extracted from paper with pyridine-water solution (1:1). The detection was performed at wavelengths of 215, 37...

We present an interactive CG (Computer Graphics) design system based on virtual woodblock printing, with the stress on an aspect of a tool to enjoy creation in a virtual space. This system is a simulation of real woodblock printing: generating a woodblock, spreading inks on the woodblock, putting a paper sheet on the woodblock, and rubbing the paper sheet with a Japanese squeegee “BAREN” in a v...

In this study, two capillary electrophoresis modes, capillary zone electrophoresis (CZE) and micellar electrokinetic chromatography (MEKC), were employed for the examination of gel ink fingerprints. The optimized CZE conditions were as follows: running buffer, 0.2M boric acid and 0.05M sodium tetraborate; pH, 6.47; detection, 214 nm; separation voltage, 20 kV MEKC conditions were as follows: 20...
