CMYK number

[GregT]

I have a customer who is very particular about colors. We painted a sign a year ago and now she wants a printed backlit sign face. The label on the paint gives the following:
Color: Louisburg Green
Year: 2005
Mfg: HC-113
Suffix: H
I will be printing with SP300V on white translucent.
Any ideas where to get the CMYK numbers?

Any CMYK numbers you could get won't work for you system. Every printer/ink/media/resolution behaves differently.

This is a situation where a spectrophotometer would allow you to actually measure the paint and get LAB color space values that you could have your RIP convert to CMYK for your personal system. Hey! look at that, we're managing color.

Otherwise, just print one of the color charts for CMYK or Pantone on your system and pick one that is close to the paint color.

I don't know which rout you plan to take . The other suggestions are the best , but in a pinch if you have Benjamin Moore color book and a pantone solid to process or process book . You can come up with something close. If you don't have them and need some help PM me i'll give it a shot for you.

Greg, Before I'd do any printing for that client, I'd explain the difference between color that reflects light (the way the sign will look in the day) and color that emits light (the way the sign will look at night with backlight). These two colors will be very different & if your client is particular about color then a choice needs to be made by someone other than you. Samples would be in order. To get your color to look correct at night, it will appear too dark with reflected light, correct in day will be washed out at night. Good luck, thats a tough one. What I usually do is split the difference, but that means the color is never actually correct.
