I did a photopolymer intaglio printing course a year ago. Another involved process which I love. Again the final outcome can be quite different and will a suit certain negatives with a rich tonal range. You have to produce a positive image on a transparency which requires a good inkjet printer and I’m still struggling to source one since my last one packed up. I did however try one with a positive developed photo transparency but would need to experiment with developing and plate exposure.
First intaglio print. Of course I made it even harder by recovering and instant print negative then converting the scanned image to black & white. Not great quality but I can see the potential.
The digital positive was produced from this instant print recovered negative.
