We study the color reproduction of full-color metallic-ink images. Full-color metallic-ink images are prints whose contributing colorants are exclusively made of colored metallic inks. Due to the presence of metallic particles, metallic inks show a metal-like luster. These particles are opaque and hide the underlying ink or substrate. In order to obtain predictable halftone colors, we need a ju...
purpose: to report two cases of oil-drop cataract and the description of this entity. patients and findings: two women (one 46 and the other 56 years-old) presented with gradual visual loss. previous studies including ct scan, mri, vep and erg were normal. with the use of simple diagnostic tests including a multiple pinhole occluder and use of visuscope, a diagnosis of oil-drop cataract was mad...
During the last couple of years several ink manufacturers have presented metal nano-particle inks for inkjet printing. These inks provide low resistances on plastic and paper substrates, thus enabling manufacturing of high-conductivity conductors that could be used in circuit boards. Inkjet printing of a commercial silver nano-particle ink on paper and plastic substrates has been investigated. ...
We report the exfoliation of graphite in aqueous solutions under high shear rate [∼ 108 s-1] turbulent flow conditions, with a 100% exfoliation yield. The material is stabilized without centrifugation at concentrations up to 100 g/L using carboxymethylcellulose sodium salt to formulate conductive printable inks. The sheet resistance of blade coated films is below ∼2Ω/□. This is a simple and sca...
Reliable color reproduction can be achieved by establishing, using a model, the correspondence between the spectral reflectance of the printed surface and the amounts of deposited inks. In this paper, we review the main models proposed in the literature, recall how each one is calibrated and compare their prediction accuracy for several print sets. The presented models are the Yule-Nielsen modi...
The linearization curve generation is an important step in printer color characterization. The typical purpose of the linearization curves in conventional four ink printing is to compensate for dot overlapping and dot size variations and therefore to accommodate the non-linearity of the printing process. In CcMmYK “photo” printing, the introduction of light cyan and magenta inks presents new ch...
Semiconductor nanocrystals exhibit unique fluorescence properties which are tunable in size, shape and composition. The high quantum yield and enhanced stability have led to their use in biomedical imaging and flat panel displays. Here, semiconductor nanorod based inkjet inks are presented, overcoming limitations of the commonly reported quantum dots in printing applications. Fluorescent seeded...
