Issue with CMYK color values changing on me

[nexgraphics]

Hi, I have the weirdest issue with my CMYK values all the time and I dont know why. I have a client who asked for a SPECIFIC shade of blue which happens to be 100,70,0,0. Now I know my screen will never show the exact color, always shows lighter. This part is ok. But I go and change the values on the color picker, and then 10 minutes later when I come back to it, the values changed to 95,65,1,0. Why would this happen, it KEEPS happening and not just one one color, on ALL OF THEM, it just changes the numbers slightly fromw hat I put in. Any answers would be GREATLY APPRECIATED!

Thanks!

Lee

is your working document in cmyk or rgb mode?
have you got something like web safe colors or else chosen in your preferences.
first things i'll check out.
does your client want it printed?
do the test prints, it might look different on your screen.

You are both correct - I thought my system was doing CMYK automatically. Thank you!
