I have two Smith-Corona Skyriters: one is 10 CPI (Pica), and the other is 12 CPI (Elite).
I wondered which ribbon made my typewriter look the best, and got a cotton ribbon, a silk ribbon, and a nylon ribbon.
The heavily-inked cotton ribbon was not just black, but BLACK. It looked really good in he Pica machine, but was too inky for the Elite machine. Too many filled-in a's and e's.
The silk (Kores-brand) ribbon was Black, and looked great in both the Pica and Elite machines. No filled-in letters. The print was a bit uneven, but the ribbon was brand-new, and rhat might have something to do with it.
The easy-to-get nylon ribbon was not black. It was more like dark grey. Nevertheless, the output was even and readable.
But I can't un-see how pale the nylon print looked when placed next to silk or cotton. :-(
As the results are now, I *lust* for the silk ribbon, even though its about twice as expensive.
I may need to do more testing by typing 3 or 4 pages full of #'s and @'s to see if the ribbons will look better once the excess ink is pulled out.
