I need advice here. I have received an order to frame 3 very high quality prints. The photographer who took the photos said they were printed with an Epson printer and the color could last up to 200years! The sizes in cm and the cost to me- 71/48 Quoted 84$ 63/61 $92 91/61 $130 these prices for 99%museum glass. He wants to use Tru Vue museum glass or 92%protection against UV. I live in Israel so these prices are probably not what you'd pay in USA. The client is a visiting American tourist. Any advice on what markup to charge will be greatly appreciated. Thank you everyone in advance.
