12-Color Printing

RGB vs CMYK

Computer screens use RGB (red, green, blue) and an additive light model. This means when all colors are on, white is produced. Printers use CMYK (cyan, magenta, yellow, black) and a subtractive light model. This means when all colors are on, black is produced.  Your computer monitor will show many colors that are not possible to reproduce in print.

CcMmYK    
(Cyan, Light Cyan, Magenta, Light Magenta, Yellow, Black)

This takes the standard printing CMYK color model and adds 2 more colors; Light Cyan and Light Magenta. By having the lighter shades, less half-toning is done, and a better image is produced.

CMYKOGV  
(Cyan, Magenta, Yellow, Black, Orange, Green, Violet)

This adds 3 more channels: Orange, Green, and Violet, to the color model. Our printer uses this model to produce the widest possible gamut of printed color. (This is also reflected in the color dots of our logo!) We also use Light Cyan, Light Magenta and two Light Blacks to incorporate the advantages of the CcMmYK color model as well. This color space is similar to the Pantone Color Gamut on the image below.

Gamut

The range of colors that a color model can produce, as seen through the human eye, the computer monitor, or printed on paper. A color which cannot be reproduced is known as ‘out of gamut’. Read more on Wikipedia:

Hampton Roads Giclée can produce a range of colors similar to the “Pantone” (red outline) above. Most other printers are limited to the CMYK (blue outline) above.
