Chromogenic light amplifier

[Ink stained Fingers]

I'm a kind of puzzled about some property of the Canon Pro Platinum inkjet paper, it is highly rewarded in this article

I stumbled over it accidentally, when you scroll down to the description for this paper you find a statement like this:

'On top of it, a chromogenic enhancer has been added which amplifies light.' I'm not really sure what this is, googling for a chromogenic light amplifier gets me here

directly into the region of biochemistry, I'm not sure how that relates to the Canon inkjet paper

If no one knows then it can’t be disputed, and It’s probably in the realms of Cowshite..

I tend to agree with @The Hat.
Chromogenic light amplifier .. alluding possibly to the fact that this paper carries a significant amount of OBAs, which enhance the apparent 'whiteness' of the whites' by shifting UV light into the visible region of the spectrum.
Oh dear, I'm entering too into the realms of Cowshiteland..,

My only contact with Canon Platinum were the sample sheets which came with my Pro10s. Nice glossy surface, shinny and 'luminous', thanks mainly to the use of those optical brighteners. Not so different in this regard from the super cheap glossy papers sold in some supermarkets.

I first thought along some space technology - e.g a laser sword without a battery which just uses ambient light and amplifies it - or a print on this Canon paper which is that bright - by amplifying ambient light - that it can replace a display , but that is probably future tech. I concur with @Artur5 that the author may just talk about OBA's, and there are plenty in the Canon paper, but as well in lots of other papers, it is not discriminating feature compared to other papers.

I'm afraid that this would leave some stains on the paper..................

Seems to be Canon's fancy (and maybe OldTyme) way of saying OBA.

Don't have the link anymore but depending on the OBA/FBA used you can shift the effect to another part of the visible spectrum, such as yellow, that is amplified.

The OldTyme referral may be to pre-digital chromogenic photography.

Another guess is that "chromogenic enhanced" also fits Canon's lexicon - Chromalife 100 and Chroma Optimizer. It also sounds more refined/techno-geek than laundry detergents with "brighteners" to make your whites look whiter.

Yes, you can get dye fluorescent inks with every color - which convert the UV light into blue or yellow or red or ........e.g. for posters and images only visible under black light - as a visible or an invisible version

dye fluorescent inks

What I read was a chemical introduced into/onto the paper itself that has a global effect on the paper like OBA's for whitening and not an effect of the ink itself.

I remember a Canon printer which was pretreating the paper before print with some conditioner.

The Canon iX7000 used a watery Optimiser to thread paper before it printed onto plain paper, the paper path went through a bath of this stuff and out the other side, it was supposed to make the colours brighter, I was Fecked if I could tell the difference..
The paper came out limp and damp that was all…
