what does CK mean?

It's a TWO LETTER MARKING CODE

It's not terribly clear in your image, so an educated guess. You might be able to get a clearer image, angle, or another board with the same part. Get better imagery, or attach the original, not screen shot of another image on a phone..

"G3 019"

Most likely epoxy/material related, and year/week of manufacture. The product code is the one you want to read off clearly.
