The only imprint is 4 "raised lines" (I think the surface of this side of the pill is indented so the lines appear to be raised but are actually the same across the surface of this pill on the pale green side. The coloring is done so that it is colored over the entire flat side of the pill with the white part of the pill being a large part of the pill. The pale green part of the pill is maybe 1/3 deep into the pill with the remaining 2/3 of the pill being white.
