How to regard GPT or GTP

Reason of failed review:

When we make working gerber file,we usually follow the top solder mask layer and bottom solder mask layer rather then paster layer.If here’s difference between solder mask layer and paste layer, we need to confirm which layer we need follow to make the openings for the PCB.

Suggestion:

To avoid mistake in openings,we suggest you double check the solder mask layer and paste layer.If they’re different,pls correct any of then if in need.And paster layers are not quite necessary as solder mask layer for PCB production.
