Authors: Chu Fu Qiang , Li Chun Yan
Published: December 2012

The paper properties such as roughness, gloss, surface wettability and other factors have great influence on the dot reproduction attributes of presswork, and different paper factor has different effect weight on the dot reproduction. The main purpose of this paper is to provide a new method to analyze the influence of paper properties on the dot reproduction. The method is to apply the grey relational analysis to analyze the influence law and the effect weight of paper factors on the dot reproduction during inkjet printing, which could provide theoretical guidance for improving the printability of paper. The grey relational analysis is a multi-factor statistical analysis method, which is based on the sample data and the grey incidence of various factors and is used to describe the strength, size and the order of the relationship between the factors. In this experiment, five types of inkjet printing paper were used to test their printing performance, and then the dot gain data were dealt with by the grey relational analysis method. Results showed that paper properties had a great influence on ink setting. Ink drop diffused and deformed less and dot gain was small when paper had smooth surface. According to the correlation coefficient degree of paper properties which influence on the dot gain of inkjet printing, the sequence was whiteness, roughness, surface wettability and gloss. Whiteness and roughness could significantly influence dot gain, followed by surface wettability, and gloss with minimal impact. Experiment indicated that the grey relational analysis was a simple and effective tool to analyze the influence of paper properties on the dot reproduction of presswork.

Abstract: Some appropriate print samples (according to the ISO standards of ink color values) were selected to set up a mathematical model which showed the relationship between density and color. The model was based on Support Vector Machine algorithm. Another evaluation system was established based on Gray Relation to decide the contribution of K, ΔL*, Δa* and Δb* to density. The final mean square error of the training sample and testing sample was 0.001 and 0.003 respectively. The evaluation system showed that the biggest impact on C，M，Y，K solid ink density was Δa* , ΔL*, K and Δb* respectively, the grey relational degree was 0.7587，0.8340, 0.7591 and 0.8711 respectively. The results of this study indicated that vector machine algorithm could accurately predict density values from chromaticity values and that the grey evaluation system of the solid ink density can be used to evaluate how big the influence of K，ΔL*，Δa*，Δb* on solid density are in offset printing.

Authors: Luo Yun Hui , Lin Mao Hai
Published: December 2012

As color gamut of digital output device greatly affects image appearance, accurate and effective gamut description for output device is intensively required for developing high-quality image reproduction technique based on gamut mapping. In this paper, we present a novel method to determine color gamut of output device by using a specific 3D reconstruction technology and device ICC profile. First, we populate the device color space by uniform sampling in the RGB 3-Dimensional space, and convert these sampling points to CMYK color space. Then, we work out the CIE LAB value of these points according to the ICC profile of output device. At last, in CIE LAB color space the boundary of these points is determined by using a gamut boundary descriptor based on Ball-Pivoting Algorithm (BPA) proposed by Bernardini. Compared with the results generated by ICC3D, our proposed method can compute device gamut more efficiently and at the same time give a more accurate gamut description of the output device. It will be help to develop effective gamut mapping algorithms for color reproduction.

Published: December 2012

This paper provides a novel post treatment method to achieve high conductivity of nano-size silver coatings. Based on the preparation of nano-size conductive ink and conductive circuit, the printed sample and the coated conductive film were treated by series concentrations of silver nitrate solution and hydrazine hydrate solution in this order. The samples were dipped in 1%~20% solutions of silver nitrate and hydrazine hydrate successively, to form the new conductive layer of Ag particles only. It was investigated that the relationship between the thickness of printed and coated layers on photo paper and final conductivity after dipped in two kinds of solutions in turn, which were printed from one to three times and coated by screw (6#). Atomic force microscopy (AFM) was used to characterize the morphologies of as printed and coated samples. The surface sheet resistance of sample was tested by four-probe tester. It was found that when the coated silver conductive ink samples were dipped in 2% silver nitrate solutions and 2% hydrazine hydrate solution at room temperature, the conductivity reaches 0.82Ω/□. The samples with thicker conductive film before dipping need solutions at lower concentration to get high conductivity. The roughness of samples after treatment falls down, as the concentrate of dipping solutions rising. It is therefore considered that the “dip in” method provides an efficient alternative to improve the conductivity of samples.

Authors: Xu Ying Jie , Wei Xian Fu , Huang Bei Qing
Published: December 2012

The thickening after preparation phenomenon of ink refers to the viscosity of ink after preparation is constantly changing during its storage process. The appropriate increase of ink viscosity during its storage plays an important role in preventing the particles of pigment sedimentation. The utility of the ink is negatively affected by the rise of viscosity of ink that is over a certain range during the process of storage. The rise is a result of the broken of the system stability owing to some physical and chemical factors. In order to improve the stability of ink during its storage, not only the viscosity changes of ink prepared by pigment and resin with different kinds of functional group during storage are measured, but also the chemical factors contribute to the thickening after preparation phenomenon of ink are analyzed. What is more, the viscosity changes of ink prepared by different constituent content during storage are measured, and the physical factors lead to the thickening after preparation phenomenon of ink are analyzed as well. According to the research results, the functional groups of pigment and resin set off a chemical reaction in alcohol system, which is the main reason for the thickening after preparation phenomenon of ink. The constituent content of ink is the essential physical factor that influences the thickening after preparation phenomenon of ink.

For the fast and exact detection of printing color, we combine the near infrared (NIR) spectroscopy technique with partial least square (PLS) to build the detection model of printing color. Applying the 144 samples of spectral curve which obtained by the near infrared spectroscopy randomly separated into calibration set and validation set, and base on the 120 calibration set data to establish the prediction model of printing color by PLS, then this model is employed for predicting the color of the 24 validation set. The RMSEC of the 24 blocks’ color parameters L*, a*, b*, E are 0.73, 2.26, 3.03 and 1.09 respectively; The RMSEP are 0.97, 2.77, 3.57 and 1.34 respectively. Those results tell that the NIR spectrum and blocks’ color parameters L*, a*, b*, E could accurately establish a quantitative regression model, applying such model also can accurately predict unknown samples, and the results approximate to the original reference data.

Document similarity search is to retrieve a ranked list of similar documents and find documents similar to a query document in a text corpus or a web page on the web. But most of the previous researches regarding searching for similar documents are focused on classifying documents based on the contents of documents. To solve this problem, we propose a novel retrieval approach based on undirected graphs to represent each document in corpus. In addition, this study also considers unified graph in conjunction with multiple graphs to improve the quality of searching for similar documents. Experimental results on the Reuters-21578 data demonstrate that the proposed system has better performance and success than the traditional approach.

Authors: Zhou Wen Bo , Yao Shu Zhen
Published: December 2012

The degree of flexibility of workflow management systems heavily influences the way business processes are executed. Constraint-based models are considered to be more flexible than traditional models because of their semantics: everything that does not violate constraints is allowed. More and more people use declarative languages to define workflow, such as linear temporal logic. But how to guarantee the correctness of the model based on the linear temporal logic is still a problem. This article proposes a way to verify the model based on Büchi automaton and gives the corresponding algorithms. Thus the verification of declarative workflow based on the linear temporal logic is solved.

In this paper we report the preparation and characterization of the NbxSi1−x films which would be used as Josephson junction barrier layer. The compositional dependence of dc magnetron co-sputtered NbxSi1−x films on sputtering power is analyzed using Energy Dispersive Spectrometer (EDS) and X-ray Photoelectron Spectrometer (XPS) respectively. The corresponding resistivity measurements of NbxSi1−x films indicate that the film resistivity could be controlled from 0.28 to about 1.29 mΩ·cm which is useful for resistance adjustment of Josephson junction barrier layer. The surface morphology of the NbxSi1−x films is studied by atomic force microscope (AFM) and scanning electron microscope (SEM).

In this experiment, we use the opaque mirror stainless steel as the substrate to investigate decorative color variations after insertion of the Na+ ion in the film and prescribe the combination coating film with reversible and excellent coating characteristics. In manufacturing of the coating film, reactive gas pass through the metal tungsten target and form the amorphous tungsten oxide thin film on stainless steel and the various colors, such as green and pink color, on the mirror stainless by adjusting the process parameters. The coating film device then immerse in sodium bicarbonate aqueous solution and induce cyclic potential of -2V～+2V. Base color of stainless steel produce the color change reaction by inserting Na+ in the film. Experimental observations show that the green base color will transform to pink then blue and the pink base color transform to green then blue.

[Pb0.95(La0.6Bi0.4)0.05][Zr0.53Ti0.47]O3 (PLBZT) ferroelectric thin films have been synthesized on ITO-coated glass by sol-gel processing. Effects of annealing temperature on structure and properties of PLBZT have been investigated. With the increase of annealing temperature from 500°C to 550°C, the remanent polarization Pr increase slightly to the maximum value of 25.4μC/cm2 due to the improvement in crystallization of PLBZT films. However, when the annealing temperature is more than 550°C, the pyrochlore phase appear and degrade the Pr of PLBZT thin films. The lowest leakage current density of 1.8×10-9 A/cm2 can be observed in PLBZT thin films when the annealing temperature is 550°C.

Generally because of the economic advantage and stable behavior in seismic loading, shearwalls combined with coupling slabs are widely used in high-rise apartment buildings. When analyzing such structures for lateral loads, however, the question of the actual stiffness and strength of the coupling slabs arises. For more accurate analysis approach, an experimental investigation was conducted with half-scale representations of the reinforced concrete shearwalls with the opening and coupled with slabs were subjected to cyclic loads. The test results of opening installed specimen, severe decrease of strength was observed. The decrease of strength of the shear walls by installation of openings shows a great deal of difference compared to previous researches. This is because flexural capacity of the slabs is working as coupling elements for the shear walls. The critical section of coupling slabs that works as coupling elements for shear walls was a little different from the results of previous researches.
