"Do the monitor and the print output match?”
We held a lecture on the Basics of Color Management.

Color management is to "match the monitor and print output" by adjusting the monitor and creating an ICC profile for the paper. Tomikawa is the only person in Japan who can give the lecture on color management. Wherever we show the artwork at the portfolio review abroad, people praise the beauty of the print. This is Tomikawa’s attribution for us. As a technical director, he has been teaching us his expertise. This time he shared his tips with many people at the lectur.

Color Management and Monitor Calibration

Samurai Foto Study Meeeting

The Color Management course was held for the first time in more than 5 years. A lot of people attended and the course was a great success.

EIZO provided a hardware calibration monitor, and VINCERO provided a color chart, a color checker display that can calibrate the monitor, and the color checker studio for creating ICC profiles.

The main topic of this 3-hour course was “How does the RGB data captured by a digital camera make a process to appear on the paper from the printer?”. By understanding the process and how it works, you can turn your digital data into actual prints.

This conceptual diagram shows the flow and structure (system) of color management. Since digital cameras are made up of data (numbers), a color space (color space) is necessary to represent the data as colors. It becomes “color” when it is specified.



Many people may have heard of sRGB and AdobeRGB. They refer to color spaces: RGB means data. R (red), G (green), and B (blue) have their own numerical values that are converted to each color by applying the numerical values within each color space.



The color space of the camera is represented by sRGB or AdobeRGB. Even if the RGB values are the same, the colors will change if the color space is different. The value range is from 0 to 255. “R255, G0, B0” represents the color of red, but the color itself changes slightly depending on which color space is applied.


This time, he talked about the basics of color management, but he also gave a simple lecture for the actual monitor calibration.


Color matching between monitor and print


To begin with, printing means transferring photographic data with a wide color gamut to inkjet paper with a narrow color gamut. Therefore, it is necessary to know the characteristics of the paper and the printer driver.



The variety of printing papers has increased since the early days of digital cameras. The paper that glows blue under a black light is glossy paper with a fluorescent brightener that tends to turn yellow. Nowadays, many kinds of printing paper are available, not only matte paper, but also a variety of Japanese washi paper.



The ICC profile is necessary to maximize the characteristics of the paper and the printer to print exactly as seen on the monitor. Once the profile is created, the prints can be made almost exactly as seen on the monitor.



VINCERO's color checker studio is used to create ICC profiles. It is an easy-to-use spectrometer for everyone from print enthusiasts to professional photographers and graphic designers.

X-rite, Tomikawa's company, uses the i1Pro, which is an amazing device that can calibrate monitors and read hundreds of color patches to create ICC profiles.

Using a profiler like the i1Pro, we printed a color patch on paper and then measured the color to create an ICC profile. We can also measure the Lab value. This also allows us to see how far the light colors go and how far the blacks go.

i1 Proなどのプロファイラーを使って、使用するプリンタで用紙にカラーパッチをプリント。それを測色してICCプロファイルを作りますが、Lab値というものも測れます。それで明るいところはどこまで出るか、黒はどこまで出るかを見ることもできます。

Simulating colors in Photoshop before printing


It is convenient to create an ICC profile for the paper so that you can simulate the color tone and brightness in Photoshop before printing. Since you can correct the colors while checking the printed image, you won’t waste paper and can save money.



If you are printing the photo with the ICC profile created in advance, you don’t need to use the printer driver. In this case, select “No color correction” for the printer driver.



For Photoshop print settings when printing with an ICC profile, select “Color Management by Photoshop” and select the ICC profile for the paper you are printing on.
