Free Color Management Essay Sample
Color management refers to the process of controlled conversion of color representation of various types of devices like the image scanners, film printers, TV screens, offset presses, digital cameras, monitors, and computer printers. This process uses the international color consortium compatible management systems. This is from the fact that the ICC has developed and defined a standard for color matching. This is at the OS level. The ICC has also developed color profiles for many of the devices that are used for the color spaces and the device link profiles that represent the actual transformation of color to the source. Color transformation looks at the transformation in the way a color is presented from a color space to the other. This transforming of color space to different out put devices is normally arrived at through referencing of the profile data into what is referred to as a standard color space. Conversion of colors to a selected standard form from one device and from the color space to the colors of another is considered an easy practice. This is possible by making sure that there are many possible colors covered at the reference color space. This process is thus very important in enabling one to exchange color from a wide range of color output devices. This process is thus an important aspect of color management.
The purpose of color management is to come up with clearly distinct match across the color devices. For the case of a video, it should appear the same way in a plasma television screen in a computer LCD monitor and also in a print frame of a video. So long as these devices are able to deliver the color intensities that are required, color management will bring the same appearance in all these devices. To get good results one can use equipment and procedures that are outlined in printer calibration and also in monitor calibration. In order to achieve effective results it is important to use color management. This is in the fact that color management will improve the color match between the printer and the monitor. Color management reproduces color very precisely, set out image to be printed on a large format. This works with nonstandard inks and also with fine art paper. All these processes are only achievable through color management.
Spectrophotometer is defined as the quantitative measurement of transmissions or reflection properties of a material. This is looked at as a function of wavelength. Spectrophotometer deals with near infrared, visible light and near ultraviolet. The process of spectophotometry makes use of a spectrophotometer. This is a device that is used for measuring of light intensity. The light intensity is normally measured as a function of the wavelength of the light source. It is thus important in measuring of the reflection or the transmission property of a given wavelength. The spectrophotometer is mostly used to ensure the transmission or reflection of solutions or transparent material found for instance in polished surfaces. It is therefore also an important tool for color management.
The digital assembly is Company that is based in New York in the United States of America. Digital assembly is a private company. It is recognized in the field of colors because of the range of commodities that it produces that are useful in the field of colors. Digital assembly is renowned for the development of computer forensics and data recovery software that is used by Microsoft windows. The software includes the adroit photo forensics and the adroit photo recovery. This is very important software especially for the aspect of recovery. Its software involves issues to do with colors and the way it can be sued to recover and view material.
To achieve the consistency of colors on press, it is important to control and measure the color and the contamination levels. Spectrometers and colorimeters are normally used for this process. These instruments are important in that they are able break down the appearance of a color. This breakdown is in the form of its saturation, its hue and terms of lightness. This is normally achieved by making a measure of the electromagnetic footprint of an ink. However, in the absence of such machines as the colorimeter and the spectrophotometer one can use the densitometer to calculate the grayness and hue error of colors. This can then determine the contamination present in the color processes. Hue Error and grayness are therefore, calculated so as to measure and ensure control of contamination available in printing ink’s grayness is that aspect of color that makes it look dirty or dull and therefore taking away the brilliance or the saturation of the ink (Tapp 114). This however does not necessarily bring about change in hue error color. Grayness can thus be looked at as the measure of the lower contamination of a given portion of ink. On the other hand hue error is defined as the measure of the larger portion of contaminated ink. From both hue error and grayness we note that ink may back trap when being applied on another bringing about contamination, in such a case hue error may be used to recognize such a problems
Printing plates differ in as per their own technology. They are classified according to its; offset, letterpress/flexographic, gravure, and the type of its screen printing. All this comes with its own way of color management mechanism. Each printing is specifically made for each primary color of the planned print; therefore it is to control in order to come with a full color management. Printing plates are normally used in such processes as offset lithography. Printing plates are used to transfer images onto paper or other or onto other substrates. These plates are made up of a variety of materials including rubber, paper, plastic and metal. The image is normally put on the printing plate by use of photochemical, photomechanical or even the laser engraving processes. In most instances the printing plates are put to a cylinder in the press. It ten follows that ink is applied onto the image area of the plate. This is ten followed by transferring it directly to a paper or first to an intermediary cylinder before putting it to the paper. For the case of screen printing the screen is much the same as printing table. This can also be made both photo-chemically or sometimes manually by the use of a porous material or using a stainless steel mesh that will be stretched over a frame (Kipphan 493).
Image processing is a form of signal processing. Its input is an image for instance like that of a photograph or that of a video. The out put of image processing is normally an image or some characteristics and parameters that are related to the initial image. Image processing involves looking at the image as two dimensional and then using the techniques of standards signal processing. In many instances image processing involves the digital image processing but still there is optical and image processing in analog. These processes are applied in quite a number of fields including computer vision, optical sorting among others in all these case color is involved to a great deal.
