Screen calibration notes

Calibrate the screen
    in the past, many people say the screen calibration (Calibration) is to adjust the screen to print, general practice is a print manuscript as the base, then using software provided by the company such as Adobe Gamma or directly on the monitor calibration to achieve color prints have similar or identical colors. But this is a way not previously ICC workflow, which can only achieve the purpose of his draft, may also not every software will show the same results. This is not a part of central control to uniform color, so Apple a few years ago developed a system extension program, called ColorSYnc. This is the use of software systems to the central processing of color, but this central control needed some information on the color characteristics of different equipment, which called the ICCProfile, making them ICCProfile requires appropriate hardware and software can be brought to fruition.
    screen calibration of primary work
    screen calibration we can is divided into two Department copies, first is environment of control, because screen although is a transmission type of display, but screen picture tube of surface also will by environment around of light effect, for example light directly irradiation to screen Shang Shi, image of contrast real-time will reduced, its truth is picture tube glass Shang reflection out indoor of light, Make black parts fail to produce sufficient black. If the Interior lights off, and increased the contrast on the screen immediately, but no one likes to work in the all black environment, making workers feel uncomfortable. A better approach is to indoor lighting appropriate controls and prevents light from direct exposure to CRT glass, is a very efficient way to screen and block part of the light.
    stable and and standard of lighting
    just said will indoor of light appropriate to control makes screen of contrast has good of results, but many friends will ignored has manuscript of lighting, dang we control has light cannot irradiation with screen, relative to screen on both sides of of lighting is insufficient of, and color temperature also no, so best can has a stable and is standard of see draft lightbox. This light usually is the result of precise design and is an Internet standard 5000K color temperature, light reflection angle will not cause glare and lighting was average.
    temperature ClolrTemperature
    color temperature that is used to refer to the degree of white light hues, with the quantity of light color. According to the scientific theory, a completely absorbing and radiating capacity of standard black body heating, temperature increases have also changed; black body heat to the appearance with which the light source is close to the color temperature, defined as the color temperature of the light source, referred to as color temperature, the absolute temperature in k (Kelvin, or Kelvin) for the unit.
    color: blue, color temperature higher favor red color temperature more low. Day by day light color will also change over time; 40 minutes after sunrise the light color is yellow, color temperature 3000K; midday sunshine, and rose to 4800~5800K, cloudy noon is about 6500K before sunset the light color red, color temperature is reduced to approximately 2200K. Artificial light to score the tungsten filament bulb 2000~3400K, m light pipe 2600~4000K, General white light 6000~8000K, and our design and printing industry, 5000K standard light tubes will be required.
    why we have standard colours too! Since the 5000K the color temperature of the light source.
    (a) in the middle of the visible spectrum,
    (b) is the white color balance,
    (c) will not be color-neutral,
    (d) internationally recognized standards.
all colors on the computer screen is hard to replicate, we come to understand that actually is impossible on the screen displayed the image on the paper without deviation, and because on the screen and paper colors are on completely different physical phenomena.
    screen calibration and characterization of
    of all colors on the computer screen is hard to replicate, we come to understand that actually is impossible on the screen displayed the image on the paper without deviation, and because on the screen and paper colors are on completely different physical phenomena. Different screen color display can be a big difference, and temperature of the screen is another factor one screen in the opening few hours later, the colors may appear different, hardware aging also affects color stability; p on the screen will decline over time. Finally, your work environment the external light source will work, because when they are projected on the screen, and screens of color mixing.
