The color reproduction of digital still camera does not, in general, match those of the final output device. Because color gamut of these devices is different, it is therefore necessary to take account of a way to match. The way uses the optimized profile to output device an image. This paper proposed a way to create the input profile of digital still camera for standardization soft proofing process. The results of proposed way showed that for input profiles equivalent, good results relatively. In this paper, an experiment was done where the illumination sources used as the standard illumination 5200K and illuminated at a $45^{\circ}$ angle in the best illumination efficiently. The white balance was in mode 'custom' : aperture F11, exposure time 1/60s, ISO50, focal length 80mm. The images were exported and saved as 16bit RGB TIFF(AdobeRGB, sRGB, ProphotoRGB) images. To do the test, the RGB values of the RGB TIFF images are processed through the ICC input profile to arrive at processed $CIEL^*a^*b^*$ values. A profiling tool such as ProfileMaker 5.0 and Monacoprofile 4.8 are used to do this. The processed $CIEL^*a^*b^*$ values are compared to the reference $CIEL^*a^*b^*$ values and these two values are used to calculate a ${\Delta}E{^*}_{ab}$.

Since domestic offset print quality control depends on the experience of persons in charge rather than objective data, the standards from the data are needed for the well-organized quality management of high-quality prints. Based on the ISO standards, now the standard specifications, such as GRACoL 7, SWOP 11, SNAP, G7 in America, and EURO Color, ECI, BVDM in Europe, and Japan Color 2001, Japan Color 2004 in Japan, are employed. There exists KS for domestic standards. However, since it has been directly imported from ISO Standards, there are discrepancies in printing materials and media. Although the quality management of commercial prints has been focused and studied. For this circumstance, standards are needed for the production of prints to meet international standards. This paper aims to find out suitable ways to approach domestic printing standards using densitometric method and colorimetric method. Printing experiments on this study were performed with domestic process color inks(Cyan, Magenta, Yellow, Black) and domestic coated papers, under the same conditions as the actual commercial printing processes. In densitometric method, how to set up the optimal solid print density was studied through three tests such as the ways to match solid print density and print contrast to GRACoL standards respectively, and the way to get the highest contrast. In colorimetric method, how to get solid print density with the minimum color difference between the $CIEL^*a^*b^*$ color specification values in GRACoL standards and the measured color specification values in prints, was studied.

Generally, if RGB image is sent to the printer when we print a digital photograph, the printer will convert RGB to CMYK by the inner built-in drive. Because the difference between color domain of RGB and CMYK will cause that change and difference. The most common way to solve the problem is to convert colors by using ICC profile at RIP software or to adapt automatic color converting from the software of the original printer. So we intended to study show which way is most efficient to the digital output and which color mode device is the best based on the printer's own drive in this paper. we tried to observe and check the extended range of color space such as AdobeRGB as well as CMYK and sRGB. Then we made sure which is the suitable color space. Besides, When we convert RGB mode into CMYK mode by utilizing RIP software and adapt the printer's ICC profile made by our selves, we evaluated the output we get and compared the result with extended RGB image. The results are as follows. In case of RGB mode, the printer requests RGB, and that makes the color space more efficient than CMYK's. Converted to CMYK by utilizing RIP software, the chroma is more linearized than the one produced with its' own driver. Compared with sRGB mode's color gamut, AdobeRGB mode's color gamut and CMYK mode's color, CMYK mode's color gamut is the smallest among 3 of them. CMYK mode's color gamut by utilizing RIP software can be changeable. that can be small and narrow or wide and broad. In other words, the volume of color gamut depends on how CMYK is linearized. The color space of sRGB is more advantageous than the one of AdobeRGB in color-reproduction printed. But in the group $-b^*$, the chroma leaves behind in terms of reproduction, In the group of $-a^*$, the chroma is excellent relatively. Visual evaluation of the image, AdobeRGB image has not many reproduction colors. Specially, according to printers' characteristics, Group B of AdobeRGB and sRGB color space is a long way behind In terms of reproduction but Group Y is excellent relatively.

Computer to plate technology(CTP) have become fully commercial. The current wide range of computer to plate system and plate makes many potential customers insecure. This process which began around 1995 has now been successfully completed, so that a wide variety of high performance systems is available. The computer to plate method of producing printing plates eliminates films from the production process, thus reducing costs and shortening production times. To discover the optimization formulation of sensitized materials we were changed formulation of resin and violet solution in thermal sensitizers. Also we were analyzed the CTP plate's surface and the result of coating and development at each sample. we were analyzed the effects of development condition as temperature and speed, the plate wear of printing test in C, M, Y, Bk ink. This paper aims to find out suitable ways that we can develop a domestic CTP plate.

Measuring ink penetration is one of the best ways to know paper printability. Ink penetration was effected by physical properties of newsprint paper. This study was carried out for the purpose of improvement printability with ink penetration of domestic newsprint paper. The samples were prepared by means of 20 newsprint paper manufacture company in Korea, and were tested by IGT printability tester. The results of this experiments showed that the depth of ink penetration according to the printing pressure. The maximum points in ink transfer curve and the coefficients of oil absorption of the papers also depend mainly upon the situation of anchor points.

The purpose of this study is to provide a executive guideline of humor in Print advertising by analyzing the copy style. For this aim, in-depth analysis about the copy style of humor in Print advertising collected by the web-site of TV cf from 2005 to 2008 was performed. In conclusion, findings showed that the copy style in the pattern of expression was focused on the psychological arousal and incongruity and the pattern of damaging and attacking someone's prestige was considered to be significant in some degree. It was also found that the copy style of humor in Print advertising in the method of expression was focused on the factor of pun, jokes, double-meaning but the factor of satire, irony and turns of phrase was a minority.

The purpose of this study is to provide necessity of job stress management to chief executives officers at small and medium size printing companies. At the same time, this study offers information of successful job stress management. When managing job stress is successfully accomplished, it increases job involvement of workers and brings high productivity eventually. Independent variables are decision-making right at the job, insecurity of job, and unreasonable reward at the company, while job involvement is dependent variable at this study. After analyzing data gathered, decision-making right influences job attachment and pursuing job outcome. And insecurity of job, that is the difficult job transferring, is significant to job accomplishment.

These are efficient management and the improved process and productivity are getting more important. Such trends improved in the functionality and automation. This paper tries to find out how technology for CIP3/4-based process may be applied and resolved. Such subject includes the domestic and international cases regarding each manufacturer's CIP3/4 technology types. Another purpose is to emphasize on the needs to establish the environment. Under this environment, it is possible to integrate network in exchangeable form through JDF standard format after CIP3/4. Based on the data from this study, it is expected to collect further substantial data which is related to the domestic printing company's CIP4 operation. It will be also possible to perform subsequent studies on the proper variables of the market segment. CIP4 stands for "International Cooperation for Integration of Prepress, Press and Post-press, it is an association of around forty international companies, mostly manufacturers of prepress, press and post-press, as well as suppliers and users. In this paper, we studied on the acting application of CIP4 workflow.
