CMYK vs. RGB
Monitors, digital cameras and scanners use RGB (red, green,blue) to produce color while the printing process uses CMYK (cyan, magenta, yellow, black). Each process blends colors to produce a full range of color. Some colors do not reproduce well in 4-color process.
Color intensity and increase of the actual color gamut can be achieved by using special RIP settings and high intensity LED UV lamps to set inks instantly on a wide range of papers. 200 line screen is often considered a quality standard. Increasing the line screen to 240ls or 300ls can increase the range of color achievable on press. For a near-perfect color match, we can add a spot color or two to the job.
