Some printing presses are capable of printing with both four-color process inks and additional spot color inks at the same time. High-quality printed materials, such as marketing brochures and books, often include photographs requiring process-color printing, other graphic effects requiring spot colors (such as metallic inks), and finishes such ...
A method of full-color printing is six-color process printing (for example, Pantone's Hexachrome system) which adds orange and green to the traditional CMYK inks for a larger and more vibrant gamut, or color range. However, such alternate color systems still rely on color separation, halftoning and lithography to produce printed images.
In offset printing, a spot color or solid color is any color generated by an ink (pure or mixed) that is printed using a single run, whereas a process color is produced by printing a series of dots of different colors. [1] The widespread offset-printing process is composed of the four spot colors cyan, magenta, yellow, and key commonly referred ...
In printing, registration black is a black color that includes 100% of each of the process colors used. Typically these are cyan, magenta, yellow and black , [4] but if different colors are used, registration black marks are made with all of the colorants (inks). [4] Registration black is used for printing crop marks and registration marks ...
CcMmYK, sometimes referred to as CMYKLcLm or CMYKcm, is a six-color printing process used in some inkjet printers optimized for photo printing. [1] It complements the more common four-color CMYK process, which uses only cyan, magenta, yellow and black, by adding light cyan and light magenta .
The same approach applies if one of the colors is a spot color and the other a process color. Trapping becomes more difficult if both colors are process colors and each is to be printed as a combination of the basic printing colors cyan, magenta, yellow and black. In this case, the trapping decision depends on the amount of ‘common’ color.
In printing, under color removal (UCR) is a process of eliminating overlapping yellow, magenta, and cyan that would have added to a dark neutral (black) and leaving the black ink only, called a full black, during the color separation process. Under color removal is used in process color printing.
Gang-run printing describes a printing method in which multiple printing projects are placed on a common paper sheet in an effort to reduce printing costs and paper waste. [1] [2] [3] Gang runs are generally used with sheet-fed printing presses and CMYK process color jobs, which require four separate plates that are loaded into the press.
