We investigated the printability of fibrous synthetic papers with ultraviolet (UV) inkjet technology. Cyan, magenta, yellow, and black (CMYK) color fields were printed on two types of fibrous synthetic papers using two different wide-format UV inkjet printers. Spectrophotometric and densitometric measurements were performed on CMYK color fields with different ink coverages, along with a microscopic analysis of unprinted paper, black prints with 100% ink coverage, and a print mottle of magenta and black prints. Colorimetry and optical densities of the CMYK prints were qualitatively and quantitatively compared. Color deviations in CMYK prints were affected by paper type and were dependent on the UV inkjet printer used.

Machines for direct digital inkjet printing on cylindrical containers are a new technology out on the market. The commercialization in the industrial sector has been affected by their high precision. This led to the use of mechanisms with narrow manufacturing tolerances and to the searches for topologies that have the least accumulated error without affecting quality. Machines with topologies that work on flat substrates have printing and productivity problems working on cylindrical substrates. This research paper presents the qualitative design of direct digital inkjet printers working over cylindrical substrates comparing five mechanical topologies; three topologies with radial distribution and two topologies with parallel distribution. The aim of these topologies is to find the precision, quality and efficiency of the printer taking into account the restrictions present in its construction. Each topology has separate constitutive mechanisms, the tolerance ranges between the movements of the print head and the substrate in order to determine precision are analyzed. Out of the five topologies described and analyzed in the phase diagram in section 3, three of them meet the requirements. One of the three topologies that meet the requirements is not being developed due to current technological limitations.

This research utilizes a 2D printer mechanism from a commercial available inkjet printer, combines with hardware and software to build up a new concept 3D printer. This 3D printer can receive printing information from personal computer, and setting the required layer thickness to stack those layers into a solid model. The largest build volume is 300x420x350 mm, print head resolution is as high as 1200x2400 dpi, and the life of printer head is longer than 12 weeks which is far longer than 4 weeks of Z Corp’s. There are many specifications are better than or equivalent to those of Z Corp’s Z-510 which is the state-of-art machine of this powder based rapid prototyping.

Abstract Flow simulations of jetting of inkjet drops are presented for water and ethylene glycol. In the inkjet printing process, droplet jetting behaviour is the deciding parameter for print quality. The multiphase volume of fluid (VOF) method is used because the interaction between two phases (air and liquid) is involved in the drop formation process. The commercial inkjet printer has a nozzle diameter of ∼73.2μm. In this work, a simulation model of inkjet printer nozzles with different diameters 40μm, 60μm, and 80μm are developed using ANSYS FLUENT software. It is observed that when water is taken as solvent then the stable droplets are generated at 60μm nozzle diameter till 9μs because of its low viscosity. For higher diameter, the stamen formation is observed. Ethylene glycol stable droplets are achieved at 80μm nozzle diameter till 9μs because of their high viscosity (∼10 times that of water). Along with the droplet formation, the sustainability of the droplet in the air before reaching the substrate is also important. The simulation model is an inexpensive, fast, and flexible alternative to study the ink characteristics of the real-world system without wasting resources.

nkjet printing technology can produce beautiful images not only on plain paper, but also on various kinds of printing media including a piece of cloth. Some Japanese companies have already stepped into the textile inkjet printer market, but making a profit is not easy so long as we look upon the inkjet printing technology as an alternative means of textile dyeing. Cost reduction is necessary as a whole for the inkjet printing systems to come into wide use in the textile dyeing industry. This paper describes current textile inkjet printing technology.

In this paper, barium titanate films were prepared by different deposition techniques (spin coating, office Epson inkjet printer and commercial Dimatix inkjet printer). As inkjet technique requires special rheological properties of inks the first part of the study deals with the preparation of inks, whereas the second part examines and compares structural characteristics of the deposited films. Inks were synthesized by sol-gel method and parameters such as viscosity, particle size and surface tension were measured. Deposited films were examined by optical and scanning electron microscopy, XRD analysis and Raman spectroscopy. The findings consider advantages and disadvantages of the particular deposition techniques.

Light Excitation

The formation of color images are generally divided into two methods: additive color imaging based on color light mixture and subtractive color imaging based on colorant mixture. Additive color imaging refers to the color image mixed by a certain percentage of the three primary color lights: red (R), green (G) and blue (B), such as LED display, cell phone screens, digital cameras and others. Subtractive color imaging refers to the color image generated by light mixture reflected by each colorant, due to some light of different wavelength in the white light separately absorbed by certain colorant after mixing a certain percentage of the three primary colorant: cyan (C), magenta (M) and yellow (Y). Inkjet, color laser printing, inkjet printing, etc. belong to the subtractive color imaging. Most commonly, printing also belongs to the subtractive color imaging. This thesis is based on the characteristics that fluorescent materials can produce colors under UV excitation, designing and preparing three fluorescent inkjet inks which can respectively produce red (R), green (G), blue (B) under UV light excitation, using inkjet printers to print color images, investigating the imaging mechanism of the additive color based on fluorescence inkjet printing, and observing the imaging results. The results show that color effect of monochrome image is good, and the color deviation is large after overlapping different colors.
