Description: With the advent of the modern digital technology, users can now capture an image and reproduce it between different media, such as display it on LCD or CRT monitor, print it on desktop printer or send it to a press. The challenge is then to maintain the accuracy of an image colors during this reproduction which has led to the development of Color Management Systems. Using this system, the color reproduction across-media will be accomplished using devices ICC profiles that describe each device color characterization data in a standardized format.

ICC profiles use a multidimensional Lookup Table (LUT) to maps the device independent space to the device colorant space. This LUT is constructed based on an estimated characterization device model (using data fitting and interpolation function and a set of measurements data) to speed the transformation performance. This research attempts to study and propose a new optimal characterization function along with interpolation methods that can be used to smooth the noise. It will also use the new characterization model to construct a LUT using a C++ program to improve the performance of color transformation across-media and thus achieve high image quality. The Delta E error will be computed to evaluate the accuracy of the characterization.

Description: Wood free papers have been prepared previously. Zeolite-based TiO2 paper decomposed gaseous toluene very effectively with UV irradiation and the removal efficiency was greater than that of a group of comparisons with the other photocatalytic papers. Natural zeolite plays an important role in both increasing the retention rate of TiO2 nanoparticles and enhancing photocatalytic efficiency of the paper. The coatings which also provide good optical properties and barrier protection are proposed as an alternate route to photocatalytic paper. With different kinds of binders and other pigments, better photocatalytic activity and good optical properties may be achieved.

Description: Increasing demand for lighter grades of printing grades of paper continue to drive the need for alternative processes, methods and techniques in papermaking. The high cost of high efficiency opacifying pigments makes for a lucrative market in the papermaking pigments and fillers sector. The pressure to reduce costs is creating difficulties for papermakers due to demands for better paper quality. Understanding the science of papermaking is critical in the development of alternative methods and products to attain desired paper properties. With lighter grades, maintaining opacity and strength is vital in the print industry. This paper is about the application of a new pigment initially developed for the paint industry in the production of LWC paper.
