Chromagraph DC 300 B (1975)  
         
 
This scanner has a length of more than three meters, the weight is a about one ton. The scanner has a scanning drum and a recorder drum for the offset plate. Both are fixed on one axis and rotate at the same speed (See also Tango)
 
The operator could not see the image while adjusting the color corrections to assess the effect of the color corrections (the image was not yet scanned or saved). So, the operator needed a lot of experience to adjust color corrections because the result was only visible when the image was printed.
The scanner can change the scale of an image during scanning, i.e. generally enlarging was used.
