From the above, it can be seen that the background between and around the color swatches is used to provide the uniform reference color, e.g., the gray color from the black ink in the preferred embodiment, and is formed from one or more pens from one or more second printheads, while the color swatch is formed primarily from inks from pens in one or more first printheads. It is a good illustration of the dangers of linear gamma image storage as well as a clear & clean image for testing profiles while still retaining the appearance of a real-world scene. Jay S Gondek Accordingly, it can be seen that a significant improvement is achieved in the current scheme of ink pen calibration by using a uniform background as an ink reference to limit contrast effects, and in a preferred embodiment, subtending a smaller angle with the calibration matrix of color swatches to take advantage of the concentration of eye receptor cones. LaserSoft Imaging now provides color calibration targets according to the previous IT8 standard 12641-1 as well as according to the new design 12641-2. Enter the dark web.
