We propose oblivious printing, a novel approach to document printing in which a set of printers can cooperate to print a secret message—in human or machine readable form—without learning the message. We present multi-party protocols for obliviously printing a secret in three settings: obliviously printing the contents of a ciphertext, obliviously printing a randomized message, and generating an...

In recent years, inkjet printing, as a new method to fabricate microdroplet microarrays, has been increasingly applied in the field of biochemical diagnostics. To further improve the general applicability of the inkjet printing technology in fabricating biochemical chips, in this work, we introduce a model to describe the multiple injection procedure implemented by the inkjet printing approach,...

background: this study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the digital imaging and communications in medicine (dicom) format file. materials and methods:  to create the bolus with a 3d printer, we converted data in the dicom format to the stereolith...

In this paper, we propose a physically based model for the printing process in the virtual woodblock printing for improvement of printing quality. Virtual printing is a simulation of real printing using “woodblocks”, “a paper sheet”, “a BAREN (Japanese squeegee)”, and “inks” in a virtual 3D space. A print is synthesized by an interaction among them, and it is very important to study physical pr...

Electrohydrodynamic (EHD) jet printing is a direct-writing technique which ejects ink through a fine nozzle using an electric field, which has the advantages of high-resolution, rapid printing speed and a wide range of ink selectivity. In this article, the EHD jet printing system is utilized to print patterns of polystyrene (PS) nanofibers. The effect of parameters such as ink concentration, wo...

Interest in 3D printing has greatly increased since 2013. With 3D printing high part complexity at no additional costs can be achieved, beside of efficiently using the raw material. This article reviews recent developments in 3D printing, with respect to the use of wood. Three examples are given on how wood could come to 3D printing: development of bio-based filaments, printing wood-like 3D obj...

Abstract—The objectives of this research are to produce prototype coconut oil based solvent offset printing inks and to analyze a basic quality of printing work derived from coconut oil based solvent offset printing inks, by mean of bringing coconut oil for producing varnish and bringing such varnish to produce black offset printing inks. Then, analysis of qualities i.e. CIELAB value, density v...
