Card Marking - History

History

Historically, the first attempts to mark playing cards involved bends, crimps and tiny bumps, which are called blisters (and resemble the Braille script). Later, when the first designs appeared on the backs of playing cards, cheats began altering the designs on the backs of cards. Hustlers have tried using various inks, pigments, scratches, etc., to add or remove lines or patterns from the back of the card design. Some varieties of card marking include block-out work, cut-out work, scroll work, shade work, tint work, etc. Here is a simple example of how block-out works and die in a hole cup. can be done.

However, more recently, science and technology have also enhanced marked-card techniques. The most state-of-the-art technologies are variations of shade techniques. These new technologies are the most deceptive and futuristic methods for marking cards. Traditional block-out and/or cut-out work have the disadvantage that they must be read close-up, because the marks are small. On the other hand, another advantage of luminous and juice marked-card technology is that they can be read close-up or from across a table.
