You use a ruler to measure the card for factory miscut and min size. You use your eyes to check for trimming.
Hold the card horizontal to your eyes and bring your eyes from the left of the border to the right of the border. Does it seem wavy at all? Is there any inconsistencies? After you check for that you are going to look at the paper fibers and see if it has a factory stock, if it's smooth (trimmed) or some other method.
