Have a look for a polyester twill that is acrylic coated , we get it at about 2 quid per sq meter , makes wondeful flgs , bunting, banners and teardrop type faether POS/banner stuff.
Mesh wont work well at all , its too rigid and there is no bleed thru at all – IE one side its totally white , the other printed.
It also does not survive well if its flaps , tending to tear along the “preforations” – makes wonderful roller blinds tho – its a material you can see thru one way and not the other.
