The specific Kodachrome spectral dye density and Ektachrome spectral sensitivity and resulting dye densities creates the need for filters when making dupes. The analysis is called a print-through. This is a spectral analysis. The characteristics are cascaded to determine the best filter pack. Modifyingthe filter pack doesn't give the best possible dupe from Kodachrome. So Kodak had a special Ektachrome dupe film, Type K that had spectral sensitivity and image dyes to optimize duplication of Kodachrome (K-14) Film on to a E-6 dupe film.

Good information in the data sheet, thanks. I presume the film is discontinued. Too pricey for me ($599.99 or offer), but here is some expired (2004) rolls (1000'): https://www.ebay.com/itm/KODAK-70mm...713004?hash=item1ef0aa52ac:g:tIQAAOSw54xUWi0V
