Pro9500 bronzing with IS inks.

[rodbam]

I have done all my prints so far on the OEM inks that came with the printer & I'm using the free papers that they gave away with the printer. The papers are all Canon, the Platinum gloss, the new Pro Luster & Paper Plus semi gloss. I have been very pleased with the prints on each of these papers with no visible bronzing (or is it called gloss differential?)
After receiving my IS inks & spare cartridges I took out the OEM inks & installed the IS ink carts & profiled with a Colormunki on each paper.
The prints look really good but have quite a bit of bronzing on all three papers. I've read about pigments showing the bronzing on gloss type papers but I thought the luster or semi gloss would be OK, so it looks like my only main option is the matte type papers or using OEM inks. I'm not rich enough to use OEM inks so does anyone know of a paper that prints well with IS pigment inks that is say a luster or semi gloss?

Hi Rod

Pardon my ignorance, but when you talk of bronzing, is that a metallic sheen particularly visible when viewed at an angle, as opposed to perpendicularly?

I have read of microporous glossy papers not being able to absorb pigments the same way they absorb inks. But there are papers designed for pigment. Strange that you should find OEM are OK and IS not though.

Bronzing can be a right pain in the ass when youre not using a paper that works well with your inks,
as you have just found out, but bronzing certainly doesnt take away anything from a good print.

I mostly use matte copier or semi gloss digital papers but also have a couple of HP 610 cm rolls of Gloss and satin papers
which I use for poster display and this HP gloss/satin does not show any bronzing whatsoever with I.S. inks,
so HP paper maybe the answer your looking for.

The down side of this HP paper is that while the ink has great longevity the paper starts to deteriorate after 5 years,
so its a case of swings and runabouts when using 3rd party inks and this can also relate to some glossy papers.

You could look at some of the Chinese glossy papers on Alibaba as they have made great strides into producing decent photo papers
to suit their inks which I imagine should also work well with I.S. ink.

Hey Rod

I just noticed your website and scanned through. It says a lot about your light levels, you leave the ISO set at 100. I am not sure that I have ever been that low!

It is interesting to see your interests and style, some nice work there!

Thanks Grandad35 for the references to bronzing.

Thanks Hat, Grandad & Emu. They gave me 60 sheets of A3 & A3+ Canon papers so I will use these up first & then experiment with some other papers to see if I can find one that works well with the IS inks. I was surprised the OEM pigments worked so well on the glossy Platinum paper. It's a real shame Canon seems to have discontinued making the Fine Art Matte as I loved that paper & it was under $50 for 20 sheets of A3+ whereas all the other fine art mattes are well over $100 & out of my league. I will see about some Chinese papers if the postage isn't too high.
The test prints I have done are all taped to a shelf that's facing a bright window which makes the IS ink bronzing look worse, under artificial light the bronzing can't be seen from any normal viewing angles so these IS prints will probably still work well where I normally hang them in less bright rooms like the Tate gallery, Louvre, & Museum of Modern Ahrt
Thanks Emu I haven't uploaded to that gallery site for ages (DPReview). Yes I normally try to shoot on Iso 100 as most of my lenses have Image Stabilization so it takes care of some of the silly slow speeds we can shoot at these days. We do get heaps of light down here too even on overcast days.

Rod, if you could keep me in the loop about stuff like this in case I miss it on here, that'd be appreciated.

I recently had a query about glossy papers and the 9500 in relation to another ink brand (no name I recognise) where the ink wasn't being absorbed by the paper at all so any and all intel is useful.. Can't see the forest for the trees being something I'm keenly aware of.

Gday Martin. How do I keep you in the loop? Do you mean to email you or is there some way to alert you through this forum?
My case is probably a worse case scenario because the test shots I did are just taped hanging from a shelf facing a west facing window which puts a whitish sheen horizontally across the middle of the prints at my height & the bronzing on the Canon Platinum & Luster papers is quite bad with the IS inks & hardly noticeable with the OEM inks. I also think the type of colours in the shot determines how much bronzing there is because a shot of some red flowers showed only a little bronzing in the leaves with the IS inks but a shot of a red parrot with greenish wings shows the whole wing bronzed out along with the eye. This would make me think that so far that different shades of green are a problem but in the parrot shot the green out of focus background shows a lot less bronzing than on the wing. At night under normal room light the bronzing is much harder to see.
I will see if I can get a shot of the two shots to post.
Here's the two files in case you can work out something from the file colours.

Here's the bronzing, it's hard to show in a shot but you can see the difference of how the glare is more even across the colours with the OEM ink shot on the right.

Do you find that all colors directly or indirectly affected by the Magenta inks show more of the bronzing and gloss differential? Or are there other colors as well.
I have found that both IS and OCP pigment magenta inks both light and regular, seem have a very low gloss to them.
