Can someone please explain to me how to print Red Sox red and blue for a little league banner. I've looked up the CMYK values for this and the internet says different values on different sites.
That's because CMYK values are device dependent. So unless CMYK values also come with a specific CMYK color space as a reference, they're pretty much useless.
The one consistent thing I've found is Boston Red Sox: #0E2B55 (blue) | #BD3039 (red). What are these values...Pantones...and how do I select these exact values in Adobe Illustrator...the Pantone library has coated this and uncoated that...what do I need for 13 oz mat finish banner material. Thanks in advance for your input!
No, as others have pointed out, those are hexidecimal values. Basically they were created for the web in the days of limited color reproduction on most monitors.
The Red Sox Pantone colors are Pantone 186 Red, and Pantone 289 Blue.
In Illustrator, always select the Solid Coated (Pantone C) library. The reason to do this is that the C version is the truest representation of the actual original Pantone ink formula on coated stock. And by using it, you can then let your RIP make an appropriate conversion to the actual profile (media type) you're using.
This assumes of course that you're using a RIP with an included Pantone library. If you're not, then when your file is generated, there will be an alternate description in the file of any named colors, and that's the color description your printer will use. If that's all you've got to work with, it's still probably the best route.
And then, of course, how well your final output matches 186 and 289 will depend on how closely the profile you're using matches how your printer actually prints.
Good news is that these are pretty primary dense colors, so for what you're doing, you should get plenty close enough.
