토너 기반의 디지털 인쇄에서 최적의 컬러 매니지먼트 적용에 관한 연구

다국어 초록 (Multilingual Abstract)

Printing company have tried for color quality standardization of digital printing referring ISO 12647-7 standard. Specially, offered new guide of color quality standardization of digital printing by proposing ISO 15339 standards that ISO is more systematic and refined for quality standardization of digital printing from 2013.
Color management method of actuality printing is basic color calibration method, gray balance management method of device. Also, there is device link profile management method that can preserve primary color usually to color management method.
Therefore, in this paper, refer ISO 15339 standards for color reproduction that is improved than existing in digital printing of toner base and experimented color management with device's default calibration method, gray balance management method, device link profile management method etc.
We the result GLACoL2006 coated1 & ISO 15339 standards and primary color CIEL*a*b* value, solid density value, color difference & color gamut, TVL(Tone Value Loss) etc. that get into standard of commercial printing comparison analyze. The results were as follows:
1. Digital printing of toner base must set TVI & gray balance that is optimized through the initialization and calibration process of device in case of print using paper that is used to commercial printing. If do not this, color reappearance of digital printing can bring serious color tolerance.
2. Color conversion of PCS base that use ICC profile is necessary process to reduce color difference with commercial printing since calibration. But, color management of PCS base was limited to reduce color difference. Was useful for color reproduction that color management that inflect device link profile in experiment result is corrected.
3. When it is digital printing of toner base among 7 profile of reference printing condition presenting in ISO 15339 standards, was the most suitable to color gamut of CRPC5 and CRPC6.
