We generally don't do custom printing of map images unless it is a bulk
order (50 or more maps). Our map production system is highly streamlined; it is
designed to print only the maps that we produce. Thus, printing of small custom orders tends to take our staff a lot of time.
Note that while our waterproof paper is proprietary, you can look online and
find printable waterproof paper that you may be able to use
yourself or take to a print shop.
