First, I appologize if I am posting in the wrong forum/section. If so please point me in the right direction

This question relates to the installtion of a drop-in sink in a laminate countertop. I have the sink installed. I put plumbers putty under the lip and followed all directions as best as I could. The sink however does not sit completely flush with the countertop. There is a gap between the countertop that measures anywhere from approximately less than a 1/16 to 1/8 of an inch. Just enough that I can see the putty. I always thought that the drop-in type sinks were supposed to be completely flush. Am I wrong or is the gap that I described ok. The only correction I can think of is that the cut-out is not big enough and is binding the sink or that I put too much plumbers putty. I doubt it is the putty problem. Any suggestions or comments welcome and very much appreciated.
