After many discussions with different people more or less prepared we concluded that not know very much about color as "optic". I will not start here a theory of color as part of the study of physics, but I draw a few concepts that help us in our work. COLOR THEORY "The color is not an object but a characteristic feature of the eye that look!" It's not exactly 1000bulbs a quote, but it reflects 1000bulbs very well the idea that we must begin to understand what we are talking here.
The perceived color is the result of the interaction between light, object and observer. Each of the three influences in one way or another color. From the physical point of view where the visual spectrum is composed of between UV (ultra violet) and IR (infrared) that is somewhere between 400 and 700 nm. White light consists of all colors in the spectrum that are mentioned above, but may be reduced to three basic components Red (Long Wave), green (medium wave) and blue (short wave). Hence the RGB color space. These three together give light or white colors. As a practical application of this color space enumerate monitor, 1000bulbs scanner and camera.
To get the colors but we care more, namely CMY (Cyan, Magenta, Yellow) must explain how these colors are formed. Waves alter objects (colors) that make up light in transmit mode or transmit reflectors. Cyan, Magenta, Yellow 1000bulbs are properties of objects (colors) to "let go" of the components they reflect light and the other two joined modeled. SPACES (MODEL) COLOR As we have already discussed, we already have two color spaces: RGB additive primaries to create or capture and the emission colors by combining twos give primary subtractive CMY primaries that creates color by reflection from a support and absorb completely additive is "opposed". 1000bulbs Both color spaces are ways (recipes) composition of three ingredients pentruaa get a specific color, and because they are dependent on the equipment they play or the observer perceives may not be used for measurement and color communication system 1000bulbs without reference. The need to better represent the colors HSL proposed a three-dimensional model, where H (Hue) is color (eg red, yellow, 1000bulbs orange, etc), S is the saturation (consistency, brilliance or lack thereof), and L is the luminosity (light or dark). The usefulness of this system is highlighted in describing three-dimensional gamut * equipment or observer, helping to offset the relationship 1000bulbs between two or more colors, and, most importantly, help communicate the color, but it must be taken into consideration that the three standardized define color: observer, light and standardized measurement equipment. COLOR GAMUT and profiles due to the need to standardize the color information were defined more dimensional color spaces, among which the most used is L * a * b. There were two observers defined standard 1931 standard observer visual CANP and in 1976 2 standard observer with additional field of 10 . Regarding light were divided light sources in 4 categories: 1000bulbs * A - incandescent light of ~ 2856 K * B - direct sunlight for ~ 4874 K * C - indirect sun light ~ 6774 K * D - standard light used in the graphic industry (D50, D65) Considering these standardized information (Lab, observer and light), 1000bulbs International Color Consortium has created and promotes color profiles (ICC profiles) Gamut represents multitude of colors (shades) that equipment / observer can reproduce / charge. Communication is done with the helper of a gamut color profile specific equipment / observer respectively. Color profile (ICC) is a "table" that defines colors reproducible (perceptible) according to a standard observer (2 or 10 ), standard light (D50 or D65) and Standard Lab values. This is done using a spectrophotometer and specialized software. Respensabil for interpretation and conversion profiles for engine color is the CMM (Color Management 1000bulbs Module). It is usually integrated into the OS used and comes with major graphics applications In conclusion I would say that the major problems that occur when printing to transfer 1000bulbs between programs or between computers caused by the use of different color profiles. Solving 1000bulbs stay primarily in calibration of equipment, and users define specific ICC profiles
