The influence prints have on the value of your original artwork depends on where you want to sell your original artwork, what galleries you partner with, and who your buyers are. It is a good idea to consult the gallerists that you work with to see if they are comfortable with selling paintings that have been printed as well. On the other hand, the popularity of a specific printed painting can add value to the original artwork, as it shows that it is a desirable artwork for many.
