Shoulders.... Weightlifting and heavy pressure

I am ten days into healing after a lot of new shoulder work. Any squat type work is going to put a lot of pressure on the new ink. (I squat 1.6x bw for reps twice a week, it's a lot of pressure) Back squats will have a bar across the area, pendulum or hack squat machines will put a pad there. (I would go to Zerchers but guess who also had a bicep done at the same time).

Its a busy tat with a lot of defined dark line work and there is another session to come in a month.

So,

How long should I wait before applying heavy pressure to the site?

I am getting bored of goblet squats.
