Teach You How to Adjust the Monitor

Why are there different colors

In the process of digital image from input device to display, then to output device or final image file, it is very difficult to maintain the original color. Because each related hardware or software has its own color processing technology and also represents different color restoration characteristics, the scanned photos and images will show different colors on the display, color proofing or printed manuscripts.

The fundamental reason for this is that due to technical limitations, each display or processing device cannot faithfully reproduce the color of the original, and different devices use different technical principles to generate color. Another point is that the printing industry usually adopts CMYK mode, while it is RGB mode when displayed on the computer. The different number of colors also causes color display errors.

Can you see the difference between the images output in two different modes (CMYK on the left and RGB on the right)

What is the normal remedy

Generally speaking, in order to compensate the influence of each device on the image color and the deviation and loss of image files in the transmission process between devices, we can compensate through two methods: the image processor can adjust the color manually repeatedly, or use the color management system to control the whole process. However, for ordinary users, if the color is adjusted repeatedly, it is undoubtedly too troublesome, and the deviation caused by the technical problems of the image processing equipment itself is not within the scope of our ability to solve. Therefore, what we can do is to correct the color difference caused by different color display modes between the display and the output equipment.

Correction of color difference using display driver

First, right-click the desktop and select "properties", then enter the "Settings" page, select "advanced", click the "monitor" page, and select "properties" to update the display driver. The display I use is LG 775ft 17 inch flat CRT display. Download the latest driver package from the Internet and find the driver installation of 775ft. If we continue to use the plug and play display driver, it will still have a certain impact on the color performance, so we choose to install the special driver for the display. While installing the driver, the color management has been updated to the management profile of LG 775ft.

The display driver system is installed correctly, and the color profile is also selected correctly

Now let's start Photoshop 7.0, click 'Edit' and select "color setting" in the drop-down menu. Then select "LG 775ft profile" in RGB (R) option in color setting, and set CMYK (c) as "retain embedded profile" and gray (y) as "retain embedded profile". Then restart the Photoshop software to complete the setting, so as to ensure that the color of the picture processed by Photoshop is similar to the last printed picture to the greatest extent, and you can get the WYSIWYG image.

Import the color profile of the display in Photoshop

Maybe some readers can't find the monitor driver and color management software because they bought the monitor earlier or don't know the model. They can also set the color temperature of the monitor to 9300k. You can specify the system ICC as the same ICC as the monitor model (usually in the monitor installation CD), such as Trinitron compatible 9300k g2.2.icm, diamond compatible 9300k g2.2.icm, or use the ICC monitor profile builder software to generate the ICC characteristic file of your own monitor. Finally, when setting Photoshop software, set the RGB of workspace to the same file name as the system ICC.

Don't think that the display driver has no function. Its function is not only to identify the display, but also includes the color configuration file in the display driver. A small operation can let us get the WYSIWYG picture.

Tip: what is ICC

ICC is a cross program standard defined by the International Color Consortium, which is used to accurately reproduce colors between different platforms, devices and ICC compliant applications (such as Adobe Illustrator and adobe PageMaker).
