More about Color: Digital Color | RGB vs. CMYK
WYSIWYG? What you see isn't always what you get...
Since RGB color and CMYK color is made completely differently, there is often something lost in translation. A lot of people will put together files for printing and see how it looks on screen, and wonder why it looks completely different when it's printed out. Sometimes people will print things on their inkjet printer and wonder why it looks different than the G7-calibrated Contract Proof we produce.
The whole RGB vs CMYK difference is also why most Commercial Printers will tend to cringe a little when we hear that files for output were originally created in Microsoft Office. Word, Excel, and Powerpoint were all designed to be business software applications. Any time you chose a color in these programs, you're choosing and RGB color. If you wanted your project to print as process color, colors will shift... ALWAYS. Microsoft "red" is a very orange-red, and their "blue" is a deep purple. The brilliant neon green that Microsoft shows on your screen, will always print like a dark almost forest green. When we show a color proof of these files, people generally seem surprised. Adobe programs like InDesign and Illustrator will handle colors much better, allowing for RGB color for the web, but also CMYK and Pantone Spot colors. Even still, computer monitors are never going to be an accurate preview of how printed colors will appear.
It's important to simply understand that color is very complicated, but you can always contact your Customer Service or Sales Representative and they will gladly walk you through the process of getting the best possible color printing for your project. If color is critical for your project, you'll always want to request a calibrated contract proof (like the proofs WE use) and in some cases you may even want to arrange a Press Proof to see your project while it's being run.
