Pre-printed Signatures

 Pre-Print (A) - This is when the celebrity signs one photo and has many copies made from it. Usually they are a just a little blurry and easy to recognize when held up to the light as they dont change color which a genuine signature might.  Sometimes they try to fool you by using a heavy stock paper with a Matt, velvety or high gloss finish on the photo. Don't be fooled,check carefully.
Pre-Print (B) - A previous negative of the signature is used to apply the autograph to any new photo negatives or older favorite negatives on a particular chosen area, and becomes part of the finished photo. Better quality than Pre-Print (A), but still recognizable as not real.
Pre-Print (C) - This is when an existing photo has a seperate signature printed onto it so it appears raised off the surface and not part of the photo. But it is also recognizable as a fake under a light or loop, and it looks unnatural.
