I am not familiar with the workflow of producing an album for vinyl and have read various things to care about like mono'ing the low frequencies, to be careful of excessive sibilance, etc. Yet, my knowledge and funds being limited, it is a bit like doing hazardous changes blindly.
So, firstly, is it something done/checked by the company who is cutting the vinyl ? And who ever used a de-esser on sibilance? Could sibilance really be a problem when pressing a LP (I read that this might cause unwanted distortion) ?
