Hi Adonys, What's ICP 1-3? Do you mean IPC?

1. Excess Plating- no excess, but filled with something which generated in the process of copper plating.

2. Dark Vias - it's oxidized.

and the solder mask printing is not aligned. The board is failed. Maybe you can ask your supplier to issue an 8D reports for you.

by the way, I recommend http://www.madpcb.com, which is a professional pcb manufacturing, assembly and design provider.
