Additive and subtractive plates. Development of presensitized plates after exposure to light depends on whether the plate is of the additive or subtractive type. Development of additive plates utilizes a developer solution that contains a lacquer and a desensitizer. As the solution dissolves the non-image area coating, the lacquer adheres to the stencil, making it ink receptive, and the desensitizer prevents the base metal in the non-printing areas from becoming sensitive to ink. Often, gum arabic is applied to form a protective barrier that prevents contamination of the non-image areas before the plate is put on press.  3, record 1, English, - additive%20plate
