제품 또는 포장 인쇄를 담당하는 사람이라면 누구나 오렌지와 같은 일부 색상은 CMY 잉크만을 사용하여 재현하기가 너무 어렵다는 것을 알고 있습니다. 네 번째 색상인 검은색(K는 키 컬러(Key color)를 의미)은 종종 감산 색상 인쇄 응용 프로그램에 추가됩니다. C+M+Y는 실제로 C, M, Y의 잉크 불순물로 인해 탁한 갈색을 만들기 때문에, 검은색 잉크를 별도로 첨가하면 CMY만으로는 달성할 수 없는 깊은 색과 톤이 생성되고, 게다가 그림자에 밀도가 더해집니다. 이러한 4색 인쇄를 CMYK라고 합니다. 이번 포스팅에서는 프린터가 CMY의 영역을 확장하여 잉크를 절약할 수 있는 다른 방법에 대해 알아보겠습니다. 인쇄기에 Gray component replacement (GCR) (GCR)와 스팟 컬러를 사용하면 더 선명하고 생생한 색상을 만들 수 있습니다. GCR & UCR 1980년대에 GCR (Gray Component Replacement)라고 ...

Extended Gamut Printing Increased product variation and lean manufacturing demands are forcing converters to work quicker and more cost-efficiently. Implementing extended gamut printing, also called fixed color palette printing, is a great way for brand owners and designers to specify achievable color, and for converters to reduce press setup time, produce smaller lot sizes, and increase press efficiency. In this video, X-Rite Pantone Color Expert Mark Gundlach explains extended color g...

Phone and computer screens are the window into the digital world of color, but if you are approving colors via email or text you need to be aware of the limitations. For starters, each of your devices relies on a different color model to display color. Input devices – your camera and monitor – use the additive color model to display color. They start with darkness and add red, green, and blue light to create a spectrum of colors. Printers, on the other hand, use the s...

위도, 경도, 고도 등의 지리적 좌표와 같이 컬러 또한 L*a*b* 값을 사용하여, 정확한 색상 값을 지정하고 그것을 기반으로 커뮤니케이션을 할 수 있습니다. What’s the history of L*a*b*? 1940년대에, Richard Hunter박사는 3차원 공간 모델인 Lab을 개발하였습니다. 이 LAB 모델은 인식된 색상 차이를 동일한 공간영역으로 나타내기 위해 구성되었습니다. 31년후, CIE는 Hunter’s Lab의 업데이트 버전인 CIELab을 발표했습니다. CIELab을 올바르게 읽는 방법은 “see-lab” 또는 “L-star, a-star, b-star,” 이지만, 일부의 색상측정 장비나 어플리케이션은 간략화 하여 L,A,B 또는 Lab이라고 표기하기도 합니다. What does L*a*b* stand for? 어떠한 식으로 CIElab을 부르던, 더 중요한 것은 L*a...

To understand how color management works, you need a basic knowledge of the additive and subtractive systems of color reproduction. Both use a small number of primary colors that combine to produce a large number – or gamut – of colors… but the way they do that is quite different. In our Color Perception Part 1: The Effect of Light post, we explained how the visible color spectrum (we know it as the rainbow) encompasses light wavelengths from approximately 380 to 720 nm....

It’s been said that everything you need to know you learned in kindergarten. Does this phrase ring true for print and packaging designers? In the spirit of spring, we attempted to use a simple childhood activity—dyeing eggs—to solve some of the most perplexing color issues facing the packaging designer/printer relationship. Here are three lessons to learn about color in print and packaging from our annual egg dyeing ...
