Abstract:

The method of transforming an original image in tones of gray into a chromatic reproduction is discussed. A computer, the SD4060, was coded to produce a series of plots, on 35 mm film, varying the number of spots and their sizes per unit area. The film was read on a densitometer to establish the correlation between the transmittance and the plot patterns. A 21-step gray scale was designed and a Fortran program, using calls to the IGS Subroutines, was written to produce two separation negatives. These were subsequently printed in register successively through red and blue filters on a negative color material. Author
