Reflex Blue

Reflex blue can be a tricky color to hit in CMYK. If you set up reflex blue in your file as a spot color, you'll have better luck hitting it because you can adjust the CMYK values. We've had success with the following values when using the Envelopes High Res 1 color profile: 

C: 75 

M: 70 

Y: 0 

K: 0 

These values can be adjusted afterward to accommodate individual needs/expectations.
