Virtually all of my prints are gicleés on paper, each one is hand signed and numbered. The paper is a smooth archival 100% cotton rag. All of my current images are printed on 28”x 22”, 24”x 20” or 24”x 18” sheets. I typically allow 1.5”-3” of white paper around the image to allow it to be framed without a mat.
I strongly suggest that you not remove the print from the tube until you are ready to put in a frame. My sizes are selected so that you can buy an inexpensive ready to hang frame. For about $20 plus the cost of the frame, Michael’s, for example, will clean the glass, mount appropriately with an acid free back and seal it in the frame, ready to hang. I highly recommend this.
