기존 책 문서인 PDP 문서를 전자책에서도 억세스 할 수 있도록 전자책의 표준 형태로 변환하는 과정이 필요하다. PDP 문서를 전자책의 대표적인 표준 형태인 EPUB3.0으로 변환할 때, 인쇄 색상 표현방법인 CMYK를 디지털 색상 RGB 형태로 변환하는데 형태의 차이로 인하여 색감이 제대로 변환되지 못하는 문제점이 있다. 본 연구에서는 변환 시 색감을 잃지 않도록 ICC 프로파일을 이용한 변환 연구를 수행하였다. 또한 전자책 독자들을 위한 상호 작용적인 시각적인 효과를 제공하기 위하여, 많은 부분의 텍스트 중 특정 부분을 인식하여 효과 코드를 넣는 알고리즘을 제안하였다.

Ink-jet printing technology with ceramic ink of the four digital primary colors (cyan, magenta, yellow, and black; CMYK) can provide stable coloration even in the high-temperature firing process. Ceramic ink-jet printing can be widely applied in construction and ceramic industries due to the advantages of accurate and fast printing process of digital images for various products. Generally, organic solvent with proper viscosity and surface tension has been used in digital ink-jet printing process. However, the needs of ceramic ink without VOCs emission is increasing. In the present study, eco-friendly ceramic ink was synthesized by combining alumino boro-silicate glass frit and $CoAl_2O_4$ inorganic pigment based on an aqueous solvent that does not generate VOCs. The rheological properties and dispersion stability of aqueous ceramic ink were optimized. Jetting behavior and printing characteristics of the ceramic ink were also investigated in detail. As a result, the formulated aqueous ceramic complex ink showed a suitable jetting behavior without satellite drop by adjusting viscosity and surface tension. The ceramic ink can be printed on glass substrate with minimized spreading phenomena duo to high contact angle.

In the modern era, the necessity of color capability in the digital era is the demand of the era, and research on improving color practice on the subdivided digital four areas that are not in the existing practice is needed. For digital majors who are difficult to solve in existing paint color practice, classes in digital color practice in four more specialized areas are needed, and the use of efficient artificial intelligence was studied for classes in digitized color and color sense. In this paper, we tried to show the expansion of the color practice area by suggesting digital color practice and color matching method based on Photoshop artificial intelligence and big data technology that existing color and color matching were practice that only CMYK could do. In addition, based on the color quantification data of individual users provided by the latest Adobe Sceney program artificial intelligence, the purpose of the practice was to improve learners' predictions of actual color combinations and random colors using filter effects. In conclusion, it is a study on the use of programs that eliminate ambiguity in the mixing process of existing paint practice, secure digital color details, and propose a practical method that can provide effective learning methods for beginners and intermediates to develop their senses through artificial intelligence support. The Adobe program practice method necessary for coloration and main color through theoretical consideration and improvement of teaching skills that are better than existing paint practice were presented.

The color image of the brand comes first and is an important visual element that leads consumers to the consumption of the product. To express more effectively what the brand wants to convey through design, the printing market is striving to print accurate colors that match the intention. In 'offset printing' mainly used in printing, colors are often printed in CMYK (Cyan, Magenta, Yellow, Key) colors. However, it is possible to print more accurate colors by making ink of the desired color instead of dotting CMYK colors. The resulting ink is called 'spot color' ink. Spot color ink is manufactured by repeating the process of mixing the existing inks. In this repetition of trial and error, the manufacturing cost of ink increases, resulting in economic loss, and environmental pollution is caused by wasted inks. In this study, a deep learning algorithm to predict printed spot colors was designed to solve this problem. The algorithm uses a single DNN (Deep Neural Network) model to predict printed spot colors based on the information of the paper and the proportions of inks to mix. More than 8,000 spot color ink data were used for learning, and all color was quantified by dividing the visible light wavelength range into 31 sections and the reflectance for each section. The proposed algorithm predicted more than 80% of spot color inks as very similar colors. The average value of the calculated difference between the actual color and the predicted color through 'Delta E' provided by CIE is 5.29. It is known that when Delta E is less than 10, it is difficult to distinguish the difference in printed color with the naked eye. The algorithm of this study has a more accurate prediction ability than previous studies, and it can be added flexibly even when new inks are added. This can be usefully used in real industrial sites, and it will reduce the attempts of the operator by checking the color of ink in a virtual environment. This will reduce the manufacturing cost of spot color inks and lead to improved working conditions for workers. In addition, it is expected to contribute to solving the environmental pollution problem by reducing unnecessarily wasted ink.

This paper develops fashion products that express the beauty of Baekje through an investigation of the unique characteristics of Baekje artifacts. This work can promote the Baekje region and provide cultural goods for local festivals to improve the economic competitiveness of the area. Artifacts from the Muryongwangreung in Gongju (the capital city of Baekje during the Woongjin period)were reinterpreted into a more modern form. Among the Muryongwangreung artifacts, the king and queen's gold coffin as well as chignon ornaments were used as design motifs. These artifacts were stylized into motifs and developed into patterns using Adobe Illustrator CS3 and Adobe Photoshop CS3. The patterns were subsequently applied to the designs of scarves and ties. The color was selected using the CMYK colorway from the Gongju city logo subsequently, a total of 12 designs (including 6 ties and 6 scarves) were developed. The design developed from this research can be applied to diverse products to promote the area. Using the research as a foundation, fashion product development based on the local culture can have a significant impact on the establishment of the Baekje cultural identity and the competitiveness of the region.

Locally Likely Arrangement Hashing (LLAH) is a method that describes image features based on the geometry between their neighbors. Thus, it has been preferred to implement augmented reality on poorly-textured objects such as text documents. However, LLAH strongly requires that image features be detected with high repeatability and located at a distance from one another. To fulfill the requirement for text document, this paper proposes a method that facilitates the word detection in infrared (IR) range by adjusting the IR-reflectance of words. Specifically, the words are printed out with two different black inks: one is using the K(carbon black) ink only, the other is mixing the C(cyan), M(magenta), Y(yellow) inks. Since only the words printed out with the K ink is visible in IR range, a part of words are selected in advance to be used as features and printed out the K ink. The selected words can be robustly detected with high repeatability in IR range and this enables to implement augmented reality on text documents with high fidelity. The validity of the proposed method was verified through experiments.

The aim of this study is to develop fashion cultural product designs in order to promote the Iksan region by using motifs from the Mireuksaji, Iksan's most representative archeological site of Baekje culture. The fashion cultural products designs developed by applying cultural resources can be effective at enhancing our cultural identity. Adobe Illustrator CS4 and Adobe Photoshop CS4 were used to reconstruct motifs from the Sumakse tiles and the bronze horse figure in the Mireuksaji Museum. The Iksan brand slogan "Amazing Iksan" was combined with the bronze horse to emphasize the local cultural identity. The motifs from the Mireuksaji were modified and stylized to make different patterns and these patterns were repeated in various ways to be applied to necktie and scarf designs. The motifs for necktie designs were double-row chrysanthemum tiles and phoenix tiles, and the motifs for scarf designs were the double-row lotus tiles and the bronze horse artifacts. Different colorways were chosen and the value of each color was displayed in the CMYK percentages. As a result, eight necktie designs and twelve scarf designs were proposed. The motifs and patterns developed in this study can be used to introduce Iksan's distinct history as the birthplace of Baekje culture. It is also expected that the result of this study can advance the promotion of Korean traditional culture internationally.
