looking for inks that WILL fade

[archie]

hello,

I am working on a project and I want to know about lightfast and non-lightfast inks.

I want PARTS of the image to fade at different rates.. say one colour/ink type to fade in 1 week, another in two etc.

Also what colours fade faster than others.

Can anyone help me or point me in the right direction?

thank you,
Archie.

You might have had better luck trying this 10 years ago.

I don't think there are any printers on the market that will do what you want with the inkset you have.  You may do better trying to figure out what you want and make a print look like it.

the other option is to get a lexmark printer or other low budget printer; they used to have poor quality ink or some third party low budget refill ink. You then need to look at hight intensity lighting, a 1000 W metal halide light  a couple of feet from the print might get your images to fade.

Wow... now this is a twist!

Unless you separate the image into portions and reprint the image with complete different inksets (and on different printers), I have no idea [other than what Jonathan suggests]. Or how about using food colors instead of real inks (this is what some of the first digital printers actually did!).

Thanks for your replies guys.

What about colours?  Don't different colours have different rates of fading?  I've noticed prints in second hand shops that are all blue and have lost all the other colours.  so is blue the last colour to fade?  Is there some sort of chart that shows this?

Don't prints do this these days?  

With my project I think I can replace the ink within a carttridge (or whatever you call them - sorry not very technical) with what I want, like food colouring as above poster suggested(thanks).  Otherwise I think I can hand paint a strip of the billboard poster by hand.  It will be text so It won't be too hard.

Thanks again guys.

A friend of mine creates paintings that incorporate tests for lightfastness of various dies, etc. Her paintings fade and/or change color over time, which is part of her artistic intent. Here is her website: [a href=\"http://www.jaqbox.com/]http://www.jaqbox.com/[/url]
Good luck.
