Wide Gamut
Ink and Rip
| With the introduction of 7 and 8 color
printers, it is possible to greatly increase the color gamut.
It is not only necessary to have a rich color ink set of the primary colors Cyan, Magenta, and Yellow, but it is very necessary to add a high saturated Red to this mix. The first element to understand is that Cyan is the Deepest primary color. Magenta is in the middle, and Yellow is the weakest. While I could go on for pages of data to substantiate that a 3 color system for digital printing is wrong, I will simply point out that it takes 100% of Magenta and 100% of Yellow to make Red. Many gloss papers can barely hold 100% of a single color at 1440 DPI, therefore to create Red it would take 200% of the combined Ink. Obviously, you can not utilize 200% of ink liquid; therefore, you must cut back the amount of Magenta and Yellow in the Rip to produce Red. You should be able to realize that Red cannot be produced to its full potential, not to mention creating a deep Red. I think you can see now why utilizing Red Ink is so important to obtaining a wider gamut. There is another advantage of utilizing red ink. By having red ink, we can create a more accurate Magenta which will produce better Purples, Violets, and Blues. Most ink manufacturers produce a Magenta that is actually a Red-Magenta in order to produce better Red and Orange values. Let's discuss producing the color Orange. Orange is made from Yellow and Magenta. With Red ink the vibrancy of Orange values increases. Look at all the advantages of utilizing Red as the Fifth Color. For 7-color printers Light Black is replaced by Red. For 8-color printers you can use both Light Black and Red. Coming soon to the Symphonic Pigment Ink Group will be Red and a new Magenta. There are several Rips that we recommend to run the Epson 7- color printers as well as Mimaki, Roland, and Mutoh 8-color printers. |
