That is an interesting question. In the nice review of the IPF8300 that Scott Martin wrote for his blog - (
http://www.on-sight.com/2010/04/25/canon-x300-printer-review/)
he mentioned that the new Canon inks did a much better job than the Hp Z3200 in regard to the effects of bronzing and gloss differential with the gloss fiber media he was testing.
After doing a lot of printing with both, he is correct when it comes to some media and not correct when it comes to others. But he never said he tested a lot of these papers.
My standard gloss fiber papers are the Harmon Baryta and the Harmon Baryta Warmtone. In both cases the HP and and Canon do an excellent job with the Harmon. I actually just did a direct comparison test last week and found that actually the HP with the gloss overcoat did a little better job. With the Canon, if you are working with a print with large areas of total black adjacent to areas of light value, even with the Harmon there is some slight gloss differential if you look closely. But it's very subtle. With the HP the Harmon is perfect.
Now with other gloss fiber media, like the Hahnemuhle Photorag Baryta, Innova surfaces, and especially the Canson Baryta and Ilford Gallerie Baryta, the Hp is in my opinion unacceptable due to obvious bronzing especially for black and white. Even spraying them doesn't remove all of it. But with RC gloss papers and the Harmon Baryta the HP is a bit better. You have to weigh that against the fact that the Canon Lucia inks are more scratch resistant than both the HP or the Epson pigments.
In both cases with fiber gloss my general procedure is to spray them with the Hahnemuhle uv coating if they are to be handled in portfolios, etc. If they are going straight into frames it doesn't matter in any case, unless you are wanting to add uv protection to the white paper base, which is a good idea for many of these papers.
All things considered the Harmon Baryta is so good with both printers that I don't even think about it anymore. But if I have to use another fiber gloss paper ( which I almost never do) I will certainly use the Canon. But since the Canon is so much faster and I use it with TBW for bw on the Harmon, I use it most of the time anyway :-) .

I've been flirting with an IPF8300 for the last couple of years now but those 3 times I've tested the printer, here in the UK and Germany, printing on semi gloss/satin media, bronzing and gloss differential were unacceptable so in the end I went for an Z3200 again. Don't know what HP will be doing, just waiting for Photokina but I know that I need a different make printer for media that the Z3200 can't handle.
John, from your experience, how is the IPF8300 coping with bronzing/gloss differential compared to Z3200? What semi gloss/satin papers do you print on the 8300?
Thanks
