Centering ceiling · Gem Mint
A ceiling from centering alone. Corners, edges and surface can only lower the grade.
Centering compares the opposite printed border widths. Equal borders are 50/50. We measure at three stations and use the most off-center part.
Graders allow different tolerances on the two faces. Measure both for a combined ceiling. Changing Front/Back only recalculates grades.
A photo of the borders cannot grade corners, edges or surface. Good centering allows a grade; it does not promise it.
On a full-art front there may be no consistent border to measure. Measure the back, or set the lines if you know the print geometry.
Take the card out of its sleeve, put it flat on a dark surface, and shoot straight above. Avoid reflections and fill most of the frame.
