Serialization is an important VDP (variable data printing) application. Incremental Information Objects (IIOs) allow us to keep track of steps in a workflow by modifying their serialized information at each step. Usually the IIO progression is defined by specific rules that change the visual properties of the IIO. We herein propose an additional constraint that defines a specific structure to the underlying bit string defining the IIO. We can then use the structure to either identify the workflow stage without access to the main ID database; modify the current workflow stage due to additional factors (user authentication, location, etc.); or use the information in the IIO as additional security information

This paper proposes a new oil painting digitization method using photogrammetry technology to compensate for the deficiencies of the existing methods. The color and the 3D geometric information of the oil painting are recovered better by acquiring several sets of orthophotomaps, and modeling accuracy is ensured with a control mesh or by flattening. The 3D reconstruction and digital representation of oil paintings mainly includes two aspects: 3D geometric information recovery of oil painting surface and color rendition of oil painting. Photogrammetry can acquire a digital 3D model of the surface geometrics of an oil painting, restore the color image and plane geometry of the painting in the form of orthophotomap, and implement the 3D digital representation of color in the painting.

As printing technology continues to evolve, the next technical challenges will most likely arise from fully automated digital print production and high-precision digital fabrication, where the printing press needs to detect faults in the printing process, automatically recover without human intervention, and construct images and/or three-dimensional objects beyond the capability of human perception. In this paper, we introduce a computational image formation algorithm of which tonal resolution at each pixel is elevated from the current technology standard of 8-bit to a class-leading 12-bit, i.e., 4K tonal resolution. Combined with a 1200-dpi high spatial resolution adaptive LED printhead, we will demonstrate that the proposed image formation algorithm can effectively address technological challenges for the future of image formation and digital fabrication technologies.

Progressive barcodes have been proposed as a mechanism to employ Data Matrix barcodes on a package or label to enhance security services for products in a supply chain by layering additional data into color channels. While the standards-based component of the code remains readable by the same equipment, the extra (color) layer requires additional processing to extract relevant information, communicate with appropriate database modules, etc. This paper examines the problem of extending the scope of applications addressable by this technique to a wider range of designs intended for mobile consumption. This challenge involves developing a scheme that can be naturally used by a greater number of mobile devices, as well as increasing the ease of adoption. The extension of progressive barcodes to the more ubiquitous QR code via embedding a compact Data Matrix code into the design is an approach for improving functionality of print and document workflows. The two barcodes can be used simultaneously for their most familiar purposes. Mobile processing allows us to leverage many more possible object-driven workflow touchpoints.

HDR Image could not be reproduced on LDR medium directly. A lot of tone information and detail information can't be perceived when we use the LDR medium, e.g., display and paper, which are the most often medium used. Although there are several progresses in traditional display medium technique including large gamut, adaptive lightness adjustment, etc., a lot of details are compressed in the reproduction of HDR image. In fact, HDR image is always correlated to the surround conditions when it is perceived through human eyes. When we perceive the scene with high dynamic range, e.g., sun rise or sun set, the responses captured by human and processed in our brain always show beautiful aspect. Theoretically, HDR image representation is highly correlated to color appearance. And the image appearance and dynamic range are always satisfied at the same time when we use our eyes as the receptor. To solve the problem that HDR image could not be reproduced in most LDR medium, a novel method based on iCAM06 and bilateral filtering was presented in this paper. Firstly, the HDR image was subjected to bilateral filtering based on the human visual characteristics. Then it was processed adaptively according to the light source information and the edge details retained. As a result, the noises in shadow portion could be reduced by the brightness adaptive function and the HDR image could be reproduced using the digital print output. It showed that the saturation of the image color was enhanced and the image contrast was improved. Additionally, the Halo phenomenon was eliminated more and the details information and edge sharpening were enriched.

In order to achieve high-fidelity representation of colors, it needs to do some purposeful interference when colors are conversed, so the color gamut mapping which is the main technology to ensure visual matching would be used during this process. And the accurate visualization of out-of-gamut between images and devices plays an important role in color gamut mapping, so a method of the 3D visualization of out-of-gamut in graphic communication based on segment maxima algorithm was proposed in this paper. And this method mainly had two steps, the first step was that the device color gamut boundary points could be obtained when used the color conversed information in digital output device profile, so as to generate accurate device color gamut. The next step was that out-of-gamut points could be obtained through making comparison between device gamut and digital image gamut, as result that the area of out-of-gamut could be presented in digital images and image gamut according to the out-of-gamut cloud dots. The advantages of this method were that it can encourage us to predict whether the image gamut is beyond the output device gamut in advance, and then it can help us to select appropriate color gamut mapping algorithm according to the result of out-of-gamut judgment, so as to realize the accurate reproduction of colors.

One of the most frequent durability issues in laser printer system is the failure of thin metal sleeve in the fuser assembly. In order to ensure the reliability of the laser printer, it is important to predict the failure of the thin metal sleeve in the fuser assembly. In this study, the method to predict fatigue life of fuser SUS sleeve with 3D dynamic simulation and fatigue simulation using ABAQUS and FEMFAT is introduced. Fatigue property of fuser SUS sleeve is correlated with MIT folding endurance test results and safety factor is calculated to endure the product life specification.

We aim to achieve stable printable 2D inks with environmental friendly solvents using a surfactant as a stabilizer. This study focuses on the influence of the pH on the stability of the MoS₂ dispersions in acetic acid at concentrations ranging from pH 1 to 5. The effectiveness of liquid-based exfoliation using shear exfoliation was also evaluated though SEM images and resulted in very thin nanosheets. We observed that at pH concentrations higher than 2, the dispersions were more stable.

Reactive inkjet printing (RIJ) was used as an additive manufacturing (AM) tool. Combined with polyurethane (PU) chemistry, it is shown that RIJ can be used to build micro-scale foams. Waterblown polyurethane foams (PUF) based on polyethylene glycol 200 (PEG200), glycerol ethoxylate (Star-PEG) and 1,6-hexamethylene diisocyanate (HDI) were used to prepare the foams. The system was catalyzed using iron(III) chloride, dibutyltin dilaurate (DBTL), diazabicyclo octane (DABCO) and bis(2-dimethylaminoethyl) ether. The influence of iron(III) chloride and DBTL were investigated by means of temperature profile measurements. The stability of the catalyst system was tested for 32 hours within the ink formulation. The ink formulations were then printed with a Dimatix DMP3000 (Fujifilm, USA) printer using a 16 nozzle printhead with a nominal 10 pL drop volume. The reaction of the inks and the building of PUF after printing were investigated by light microscopy and SEM. It seems favorable to use high amounts of catalyst in order to obtain a more porous structure.
