Can we custom the strength and flatness of PP honeycomb panel?

Firstly, considering to the panels with same weight (g/sqm)

1) If clients focus on the strength more than the flatness of surface, we will adjust our core material stronger and surface skin will be thinner, then the honeycomb structure is visible on the surface. 

2) If clients focus on the flatness more than strength, we will adjust our surface skin to be more thicker, then the honeycomb structure is not clear on the surface. 

Secondly, considering to the panels with different weight (g/sqm)

1) If the panel in thickness 3mm less than 1000gsm, the structure is visible.

2) If the panel in thickness 3mm more than 1200gsm, it is hard to see the honeycomb structure on the surface. 

Thirdly, If we produce the thickness to 5mm or above, with heavier gram weight, the honeycomb structure is invisible.
