Bronzing

A recent thread on printing mentioned "bronzing". I didn't know what it meant and I never heard others talk about it, so looked around and I found this information at www.imagescience.com.au/kb/questions/57/Bronzing+on+Inkjet+Paper :
Bronzing is an image defect that occurs with some inkjet printers and some papers. . .The new Ultrachrome K3 printers have pretty much eliminated bronzing as a problem
Bronzing -occurs- when paper is viewed from an angle, part of the image seems to disappear or takes on a uniform tone . . . because of some ink laid on the paper is not properly absorbed . . .
In general, spraying prints with a high quality coating will substantially reduce or even eliminate bronzing with typical semi-gloss and gloss papers.
With super high gloss papers. . . the spray does work but will leave a visible semi-gloss texture on the print and it isn't an ideal solution. The best option is to try another paper but the problem is inherent in current coating on high gloss papers and there is no perfect solution at this stage.
And I always wondered why spray coatings were sold and what they were supposed to do; now I know why. I hope my new insight is helpful to others.

I wouldn't worry too much; I haven't seen an example for years. They seem to have got over it with modern materials.

So is there any need for these sprays? I just heard about a spray to protect against uv light when whiteners are used with some papers. Is that one also not necessary now?
