The goal of the present work is to reduce the number of the training samples used in our color prediction model based on CIEXYZ using an Effective Coverage Map while keeping satisfying prediction. A general approach is proposed in this paper to choose the best reference combination for the training samples. The approach is based on the dot gain behavior of each primary ink, which is characteriz...

In this digital era, one thing that still holds the convention is a printed archive. Printed documents find their use in many critical domains such as contract papers, legal tenders and proof of identity documents. As more advanced printing, scanning and image editing techniques are becoming available, forgeries on these legal tenders pose a serious threat. Ability to easily and reliably identi...

The authors focus on the Fused Deposition Modeling (FDM) 3D printer because the FDM 3D printer can print the utility resin material. It can print with low cost and therefore it is the most suitable for home 3D printer. The FDM 3D printer has the problem that it produces layer grooves on the surface of the 3D printed structure. Therefore the authors developed the 3D-Chemical Melting Finishing (3...

The file transfer committee met and discussed the Mail Box Protocol RFC 221, NIC 7612. The potential utility for the mechanism was confirmed and a couple of changes suggested. We first give the changes and then restate the Protocol. CHANGES 1) The Mail Box Protocol is only to allow ASCII stings of text formatted for a network standard line printer rather than allowing other data types. 2) A new...

This series of articles reviews UHF transmission line antennas developed for RFID Printer-Encoders. It explains the basic operating principles of antennas, their effect on the printer’s encoding function as well as how the antennas influence the design of labels with embedded transponders (Smart Labels). The survey of antennas is preceded by the evaluation of antenna-transponder mutual coupling...

Gels are kinds of soft and wet materials, having many unique characteristics such as low friction, material permeability, and biocompatibility. In the last decade, the mechanical weakness of the gels has been overcome by the advent of novel high-strength gels, which promises to expand the industrial and medical applications of the soft and wet materials. Here an optical 3D printer was developed...

On online shopping sites such as Amazon and Rakuten, recommended items are displayed along with the items being viewed. We consider that certain recommended items reflect the characteristics of the viewed item. For example, “DVD-R” may be recommended with “Printer,” whereas “Printer” might not have the recommended item “DVD-R.” In this case, we may assume that the item “Printer” can print a lab...

Digital photography is gaining day by day more and more credibility over conventional photography due to a number’of factors easy to guess. Bluetooth connectivity in the digital camera provides cordless communication with PC, printer and phone resulting in better usage of digital cameras. More over, with the adequate software, the digital photographs could go directly from camera to desired tar...

Pretty printers are tools for formatting structured text. A recently taken algebraic approach has lead to a systematic design of pretty printers. Wadler has proposed such an algebraic pretty printer together with an implementation for the lazy functional language Haskell. The original design causes exponential complexity when literally used in a strict language. This note recalls some propertie...
