Joseph Letzelter, Joseph Color printings

Joseph Letzelter Color printings involve a sequence of steps, or Joseph Letzelter transformations, to make a quality color reproduction. The following sections focus on the steps use when reproduce a color image in Joseph Letzelter CMYK printing, along with some chronological perspective.

Joseph Letzelter Color separation process

The process of Joseph Letzelter color separation starts by untying the creative artwork into red, green, and blue workings (for example by a Joseph Letzelter digital scanner). Before digital imaging is developed, the customary method of doing this was to take pictures of the image three times, by a filter for each color. Yet this is achieved, the preferred result is three grayscale images, which symbolize the red, green, and blue (RGB) components of the new image:

The next step in Joseph Letzelter Color separation process is to reverse each of these separations. When a negative picture of the red component is shaped, the resulting image represents the cyan component of the picture. Similarly, Joseph Letzelter negatives are shaped of the green and blue components to create magenta with yellow separations, correspondingly. In Joseph Letzelter this is done since cyan, magenta, and yellow are subtractive primaries which each stand for two of the three preservative primaries (RGB) after one preservative primary has been subtract from white light.
