of variable thickness, especially for long runs and high color saturation; this aspect provides a very high shadow detail just like photograph. Many organizations have tried to standardize printing like Fogra, ISO, and more. Larger gamut are being built to cover more out-of-gamut colors, but designs, graphics and colorfulness of the products, are limited due to the involvement of several process variables. In publication printing, only four colors of ink are used: yellow, magenta, cyan, and black. CMYK primaries are generally used because the images to be printed have memory colors (blue sky, green grass) or colors that are obtainable within the CMYK gamut. ICC color management helps the user to build ICC profile is to establish which color is produced when a given combination of CMYK dots are printed. However flooring and wooden patterns printing industry, which often uses gravure printing, use non-CMYK primaries because they are better tuned to the limited color space of such patterns. To successfully reproduce these colors, a smaller or customized gamut is selected. Today proprietary software applications are being used for
