Whole process of textile printing is made by computer and it remarkably improves environment problem. This digital textile printing is becoming next step environment friendly textile printing method. But, still now range of textile possible for digital textile printing is limited, and also color analysis according to fiber types is not completed. The ink printed on the fabrics through DTP printer can be absorbed and fixed into textile without any blots by pre-treatment using suitable media solution for fabrics types. The chemical formulation of media solution used in the pre-treatment process varies according to the types of textiles and inks for DTP products. First, I studied reference books or articles about color analysis of digital textile printing. Second, I recorded pre-process, printing, post-process and coloring of silk, wool, nylon at same condition. After that, I analyzed $L^*\;a^*\;b^*$, Total K/S, ${\Delta}E$ and studied color intensity and coloring. According to this study, I suggested particular textile special for coloring and manual for affective coloring control. It showed that the performance of the digital printing on the Silk, Wool and Nylon blend fabrics treated by the media solution developed in this study was better than the one treated by the previous media solution for each single inks.

$TiO_2$ films are fabricated using silk printing method. Heat treatment temperature of films is 600[$^{\circ}C$]. From the analysis of microstructure, grain size of $TiO_2$ films is about $0.2{\sim}0.3[{\mu}m]$. Thickness of films is 30.19[${\mu}m$] and surface uniformity of films is good. From the analysis of crystalline structure, $TiO_2$ films transform anatase phase to rutile phase. Capacitance of films increases according to increase relative humidity and decrease measuring frequency. Hysteresis characteristics of capacitance and impedance are best at 45[%RH] and 75[%RH] respectively. Impedance of films increases according to decrease measuring frequency.

Digital Textile Printing(DTP) is appropriate for quick response system(QRS) and is closely connected with high value added fashion industry. Fashion products of high price are mainly silk and cotton. For high quality DTP products, it is important to optimize the parameters of media, pre and after-treatment, ink, printer, etc. DTP for these two fiber materials is also accompanied certainly with steaming as after-treatment process for coloration. Role of steam is like water in exhaustion dyeing. Steam can diffuse dye or ink in printing paste to fiber. Quality of DTP products depend on after-treatment processes such as steaming, washing, drying. Current production amount of DTP is smaller than one of conventional textile printing. However conventional after-treatment system has been using so far. This is mismatched with DTP in terms of process efficiency, spot work of small lot, quality control. In this study, continuous after-treatment system has been suitably designed for DTP that washing and drying are available after steaming. So, It is possible to improve efficiency of DTP process. Especially, the effects of after-treatment process, such as temperature of heat drum, steaming time on printability, color difference, color fastness were examined. Two types of samples(cotton knit and silk fabrics) were used. The results were obtained as follows : First, there is no a wide difference between the K/S values of cotton and silk treated with continuous after-treatment system and those of sample treated with conventional printing after-treatment method. So it is more effective to use the continuous after-treatment system than conventional printing after-treatment system in case of the daily throughput of 1,000 yards below. Second, after continuous after-treatment for DTP, K/S values were increased and lightness($L^*$) values were decreased. ${\Delta}E$ values were below 2.3. Third, DTP samples treated with continuous after-treatment system were tested for fastness(washing, light, rubbing). Grades of fastness(washing, light, rubbing) were above 3 grade.

Traditional tie-dyeing is widely implemented in the clothing handicraft culture in China, South Korea, and Japan. Since it was developed 2,000 years ago, it has become a popular method of fabric making in the world and is highly respected by fashion designers. Based on the existing traditional tie-dyeing methods, this study conducted specific research on the 3D printing technology of the SLS laser method and the micro tool design application method of the clamp-dyeing process. Through the experimental methods of this study, it proposes to use the "7000 Nylon" material, which is commonly used in 3D printing, to develop a new clamp-dyeing tool. This new tool can be widely used in the clamp-dyeing of fabrics, such as cotton, hemp, silk, and some chemical fibers. The applied method and principle can be consistent with the traditional clamp-dyeing method. Therefore, the innovation of tie-dyeing technology is the best protection measure for the development and inheritance of traditional fabric making. The continuation of artistic life needs originality, which is also the best response to market competition. At the same time, this new design of the clamp-dyeing tool has the characteristics of novelty, innovation, and rich changes, which aligns with the new fashion demands of current fabric design.

The aim of this study is to define the new expressive techniques for multicolored clamp resist (hyuphill) dyeing, based on empirical verification on relics that are estimated to be dyed by the exchange of more than two wood blocks: a previously undiscovered technique. Clamp resist dyeing (assumed to be made by exchanging wood blocks) have uneven resist printing lines or cloudy gradation. These are reproduced as follows: first, they have uneven contour lines, particularly with the color blue. It is possible to exchange wood blocks separately on patterns with uneven resist printing lines, and it has been verified that the exchange of wood blocks makes these irregular resist printing lines. It has also been verified that exchanging the wood blocks according to the gradation (to emphasize the cubic effect on the patterns) yields clamp resist dyeing with no resist printing lines but with cloudy gradations that have accented borders. This study provides basic information that enables methods of multicolored clamp resist dyeing through wood block exchange to be deduced (something that has not been attempted for a long time). Thus, the revival of the modern Korean dyeing culture based on the conservation and perseverance of the traditional dyeing techniques can be achieved.

Fine art production methods are frequently incorporated into animation production. The Printing Expression method is often employed among fine art production. There are three main techniques in Printing Expression: Silk Screen, Woodcut and Etching. Animations that use Silk Screen and Woodcut techniques are quite common. However, it is rare to find Etching techniques in animations. So with that being said, I would like to introduce etching animation through the work of Piotr Dumala; the well known Ink Etched film director. Also, I analyzed the characters: movement, unique texture and sensuous feeling; that only mezzotinted Etched-Animation expression technique can show. If we can expand methods on how to show our imagination through etching techniques, it can allow many directors to produce etched animation films in which they can express their imagination.

The textile fabric contains the functions of sanitation, decoration, wearing style and washing in the practical use. Among various tetile fiber, silk has less utilities than synthetic fiber in practical use although silk has good benefits of the high quality of silk fabric. Thus no textile fiber, neither natural norsynthetic, has all the functions. In this sense, many compound fabrics have been improved to reveal various functions of fabric However, this has been disturbed with the problem of dyeing, expecially in the case of compound fabric of silk. The work is carried out to improve the dyeing method of compound fabric of polyester and silk. The results obtained are as follows: 1. In the dyeing of compound fabric(P/S fabric), azo dyes was more suitable than anthraquinone dyes. 2. According to the carrier, dyeing spot was appeared by the high concentration in bath. 3. Degree of dye fixation was decreased in dyeing of methylnaptharine carrier(D.N) and anion disperser(T.S). 4. The affinity of dye was suitable in the dyeing bath of azo dye, trichlorobenzene carrier and nonion disperser. 5. Dye fixation of silk side in compound fabric by acid dye showed higher in acid bath of dyeing. 6. In printing of silk and polyester compound fabric, it must be understood relationship among fibers, dyes, and steaming conditions.

Hanji costumes has four aspects that allow the creator or artist to create many variations. The pictorial effects of Hanji costumes are produced through variations in the dyes and brushes used for its application. The amount of water and texture of the Hanji mixture also influences the Hanji clothing. This effect was expressed using a dry brush technique, a dripping technique, India inks, and fragments from other Hanji works. A second aspect of Hanji clothing is the coloring effect in the Hanji costumes. The coloring is due to the fibers in the preparation mixture and the uniqueness of the dyes. The Hanji clothing was dyed various colors and patterns by dip dyeing, block dyeing, silk screens, digital printing. The third aspect of Hanji imagination in clothing is the decorative details. The details in Hanji clothing can be seen using frills, pleats, tucks and ribbons. The last variation of Hanji clothing can be expressed through crafting techniques. These techniques are the quality of paper string, cuts in the paper and paste ingredients. With Hanji cloth, it is possible to plait, roll, and crample into other flexible & useful materials.
