18x20" is the inside dimension of the most popular frame sold by Newman. The piece of mesh is actually larger, i.e. 24" x 28", so there will be mesh to grip when inserting in the frame. Mesh is never cut. We tear mesh so the mesh tears along a thread line. You will receive a panel that is square so you can accurately align the edge of the mesh to the edge of the frame. The threads of the mesh must be parallel to the sides of the screen in order to develop maximum tension, and to avoid the risk of splitting the mesh. Buying mesh by the panel saves you time without paying a price penalty to have us prepare the mesh for you. White mesh refracts light and emulsion exposes faster than dyed mesh. Dyed mesh cost more than mesh not dyed. Mesh counts 60-180 are offered as white mesh, because the increased resolution possible with dyed mesh would not be noticeable. Mesh counts 180-355 are dyed, because typically fine details are being exposed and maximum resolution of images is required. |
