Really excellent news!!
I am looking forward to use the new Ilford Portfolio paper. I am using Ilford's photo papers since my start in the darkroom as a young pupil. I have always been very satiesfied with the quality.
Does anyone know the current expectations for archival life of this generation of RC papers?
At the Ilford factory visit we talked about that topic with the Ilford engineers. I remember especially the two following quotes:
" We expect at least 60-80 years of archival life if properly fixed and washed."
And
"We wouldn't be surprised to see in the long run similar stability to fibre based papers."
I am running a kind of long term test with Ilford RC papers: I have several Ilford Multigrade RC prints hanging on the walls. The oldest are meanwhile there for 34 years, and they look absolutely fine.
Honestly, I expect that the Ilford RC and Agfa/ADOX RC papers, which are all made with the extremely high quality base of the world leading photo paper base manufacturer, will outlive me.
But I don't expect at all the same long term stability for Foma RC papers, because they are made on a much cheaper, lower quality base (and I know photographers who have had problems with these papers). You get what you pay for.
Fujifilm had introduced their new ultra-high quality premium RA-4 colour paper "Maxima" (for gallery, exhibition, archival prints) in 2018. It is also an RC paper and Fujifilm said it has an archival life of more than 100 years.
Personally, I have no doubts in usage of high-quality RC papers for my best pictures. My long-term experiences with Ilford, Agfa / ADOX, Fujifilm, Kodak RC papers have all been excellent.
Best regards,
