Reproduction camera control system

In a reproduction camera for the production of contact screen prints from an original, including means for holding a contact screen and a light-sensitive material, means for exposing to light an original to be reproduced, an optical system for projecting a light image of the original onto the plane of the light-sensitive material, and means for controlling the light dosage of each exposure,

• a control system comprising computer means, computer output means and means for inputting to the computer means data representing the minimum and maximum optical densities of the original to be reproduced, optical characteristics of the screen being used and operating characteristics of said optical system, of said exposing means of the light-sensitive material,
• said computer means being responsive to such inputted data to determine for each said original, and being operative via said output means and said exposure controlling means to cause said exposing means to apply, a light dosage for an imagewise main exposure of said material through said screen and a light dosage or dosages for at least one of an imagewise additional exposure of said material without a screen and a non-imagewise additional exposure thereof through said screen so that a screened print is produced of which the highlight dots and the shadow dots have specific sizes corresponding substantially completely to the minimum and maximum optical densities of the original.
