A sheet of 13x19" Pictorico® OHP Film emerging from the printer. There are eight approximately 4x5" negatives ganged up on it.
The black and yellow inks in the Epson K3 set are known to be the best UV absorbers, so the print driver has been set to maximize use of those inks. The result is remarkably similar, viewed by visible light, to the appearance of ordinary film negatives that have been developed in a staining pyro formula. The pyro stain is a UV blocker and is proportional to the main silver image. Something very similar is going on here.
Printed at the standard exposure time determined by test exposures of the step tablet, things look promising in the clearing bath.
Another of the small test pairs, this time two pictures made in Iran and India back in 1969/70, never before printed in platinum.
