Yeah I am seeing a lot of these color recipe posts recently. Basically what it comes down to is someone could tell you their recipe and you can print it on your printer and it most likely won't look like the color they see on their printer or the color you are wanting either. So while 0C 100M 100Y 0K is theoretically a perfect red, once it is printed on a device, there are a ton of factors that go into how it looks once printed. For that reason, when someone gives you their recipe for red, it may work by pure luck alone but it most likely won't look like you think it will. That's what profiling is all about. So it's not that the question is irrelevant because it can get you closer to the color you want, but no one will be able to tell you what combination will give you the best color on your printer, using your profile, using your specific vinyl, using your specific ink type and brand, and your specific environment.
