Papers were "digitally" tweaked in one respect for sake of deeper DMax and steeper shadow curve contrast in relation to relatively anemic digital printing devices.
The changes to papers prompted by digital are more varied than just a contrast change. Some of those changes were to necessary to cater for the short exposures a digital system needs to make in order to maintain economically attractive productivity levels. Some of those changes were cost and complexity reductions that were allowed by digital, since direct matching between the paper and a negative was no longer necessary.
As to 'anemic digital printing devices': the exposure per pixel of a Fujifilm paper is around 10
-6 seconds. As a printer yourself, you are aware of the kind of light the paper needs to be exposed. Digital exposure systems have no problem (and never had) to beam the required number of photons in a microsecond onto the paper.
Apart from the productivity requirements, another big reason to keep exposures short is to reduce problems with halation, which were present in non-digital papers when exposed with high-intensity spot sources such as lasers. Paper got faster mainly to combat this effect, not because of a lack of exposure power.
As far as these papers being optimized for discontinuous RGB laser sources rather than full-spectrum halogen bulbs
Sort of, but not quite. It's rather the other way around. The spectral sensitivity of the paper hasn't changed much, because the spectral sensitization of the silver halide apparently hasn't changed either. There simply was no need for this. However, given the potentially available wavelengths of RGB sources, some wavelength choices are less fortunate than others. Evidently, manufacturers avoid these wavelengths. The other part of the story is that the sensitivity of the paper of course varies according to wavelength. In other words, the paper has a different sensitivity to e.g. 680nm red than to 650nm red, etc. This is accounted for in the ICC profiles, which therefore are constructed for a specific paper, and a specific printer. So there are profiles for e.g. CA Supreme HD paper exposed with a LED-equipped Chromira device and this will be different from the profile for the same paper exposed in a Polielettronica laser-equipped printer. (Laser is just one option for digital exposure; LED is used as well, in a number of conceptually distinct ways).
I wouldn't even classify cut-sheet CAii a "bastard product". It is thin, but overall, a better performer than many earlier renditions of Crystal Archive.
If today's CA is a better or worse than earlier CA papers (i.e. the ones from 20+ years ago), depends on how you look at it. For optical printing from negatives, it's far worse, because it's not compatible with that anymore, but as you and many others have noted (or rather, didn't notice), most people don't experience this as a problem. Compared to its current siblings in the Fuji paper lineup, it's the entry-level product with lower dmax, lower gamut and lower life expectancy.
If you can't get saturated colors on CAii
It's a verifiable fact that CA produces a narrower gamut and somewhat shorter-lived prints than its higher-end alternatives. For the same exposure, filter settings etc, you'll get slightly less saturated hues on plain CA than on e.g. DPII, or even CA Supreme. The difference is subtle, but clearly visible. Before I learned where the difference between these papers stems from, I actually tried it and my results match what you'd expect based on the difference in emulsion and interlayer thickness between papers. Sure, you can get saturated colors with plain CA. But there are hues towards the edges of the color circle that will print fine on e.g. DPII, but that simply won't materialize on CA. That's not quite the same as "you can't get saturated colors on CAii", which is actually a claim I can't remember anyone having made.
Moreover, there's the mottling issue that CA is particularly prone to due to its thinner emulsion layers. The same problem is also present on higher-end papers, but largely or entirely masked by the thicker emulsion layers that build more optical density. The problem is due to fluctuations of the thickness of the paper base. This was confirmed to me by Fuji upon demonstrating the effect to them, which they immediately recognized and explained to me.
There are more points I could go into, but maybe that'll be for another day. Let me explain why I'm hesitant to proceed in picking apart your posts and try to nuance or set straight a number of things.
What I've come to notice over the years, Drew, is that in your posts, there are often formulations that create problems that you're perhaps not even aware of, but that arise wherever you go and post. These make it somewhat exasperating to attempt to exchange insights with you, mostly because the term 'exchange' cannot cover the process that ensues when someone decides to respond to the things you say.
Take for instance that remark of not getting saturated colors on CAII. Nobody every said that, but it's something you state as an apparent fact, probably based on remarks from me and perhaps others along the lines of this paper not giving as saturated hues as some others (note the difference!) Misconstruing someone else's words this way creates dissent where there is none to begin with, and it's somewhat exasperating if that happens systematically, and in such a subtle way that it's easily overlooked.
Another issue is that your posts contain numerous statements that are presented in a matter-of-fact way, while on checking with in this case the manufacturer, appear to be incomplete or even inaccurate. This is likely unintentional on your end and perhaps something you're not even aware of, but it makes it somewhat frustrating to respond to your posts. This is not helped by the fact that if someone attempts to nuance what you said, they're generally welcomed by another barrage along similar lines, usually with a few added jabs to subtly discredit the responder (in your post above, the "issue of misunderstanding" remark at the start). Especially the latter only succeeds in putting the exchange on edge and adding a dimension to it that's uncalled for and very counterproductive.
I've learned (after a long time, admittedly) to take your posts with a hefty grain of salt. To add insult to injury, it's usually impossible based on the formulation of your posts to determine which statements are accurate and reliable and which ones aren't. The net effect is that your posts add a great deal of noise in addition to useful information, and due to the formulation, it's impossible to separate the two without a lot of additional fact-checking. The latter is of course a labor-intensive process and something I'm not quite willing to consistently do, not even in the scope of this subject matter that I've been putting a lot of effort into out of personal interest/fascination.
For the reasons outlined above, I will respond more sparingly to your posts than I did in the past, and will probably leave most of them to stand uncorrected and uncontested, notwithstanding the myriad subtle (but significant) inaccuracies, misconceptions and misunderstandings on your part.
