To preserve the original condition of the print, do not remove it from the protective sleeve before framing. Although the art prints are made with the highest quality materials, the inks can leave fingerprints. Therefore, it is recommended that you wear protective gloves when handling the art print. Make sure you only touch the edges of the print and not the ink surface.
If the print is rolled in a protective tube, it must be flattened before framing. But first, gently unroll it and be careful not to break the paper. Find a flat surface and after gently unrolling your print, place a board or large book on it so it covers the entire surface of the image. 
Leave it like this for at least 24 hours. If the image is still slightly curled after this time, leave it weighted for another day. 
Once the print is perfectly flat, simply place it in the frame and hang the picture on the wall.
