Beyond CMYK: The Use of Special Effects in Digital Printing
With the exception of a few devices, production color digital printing has been a process color world, where everything is reproduced with cyan, magenta, yellow, and black inks or toners. Many years ago, market leaders at the high end envisioned opportunities with value-added special effects beyond process color. They implemented the use of spot colors, clear toners, dimensional, and other effects that took advantage of the unique capabilities of digital print, namely the ability to personalize, on-demand print, and just-in-time manufacture documents that could not easily be reproduced using conventional methods. These trailblazers at the high end showed how production digital print could push beyond the short runs and quick turnarounds of much process color work.
