I did a test with HP GT52 bottled inks , used for a series of HP tank system printers,

I tested similar HP 31 bottled inks for some other tank system printers to see whether they are the same inks.
They perform - prelim. info - very similar to the GT52 inks - if it takes 10 (days) for the 106 inks to fade by an amount of x - shift of luminance - the 31 inks fade faster and reach that same level after 8 (days) - ~ 80% - already , this on a HP premium plus photo paper, measured this time with the scan of a small profiling target - as
described here , comparing data against a patch kept in the dark (in a sleeve....) i1Profiler is doing all the calculations to come to an everage DeltaE for a color and luminance shift which I use to compare the different paper/ink combinations

If I look to these 2 inks on a cast coated budget paper I'm getting this that the 106 ink on this paper only needs 6 (days) to reach that same level of lum. shift vs. the HP paper, and the 31 ink on this cc-paper gets 0.8 x 0.6 = ~ 0.5 - confirmed by measurement - 0.51
The HP 31 inks are dye inks only for C M Y, the black ink is a pigment ink - the same with the GT52 inks.
This shows how easy it is to accelerate the fading of prints by the wrong choice of materials.
Cast coated papers are budget level papers - but still in a rather wide pricing range , and there are several parameters for you to judge - pricing, look, haptik-paper back - size of the gamut - black level - fading of inks , no supplier can help you with some parameters to compare, you have to test various types to come to a conclusion for yourself; I'm using - amongst some other left overs from such tests - the Logic Seek paper which comes with some different thickness levels, has a pretty low price (via Amazon) and comes in a nice and sturdy box if you order a qty of 200 sheets A4. I know that there are other cheap papers on the market better here or there but I have settled on the LogicSeek material at this time for a cc-paper. I used some LabelHeaven paper longer time ago, but this one delivers a better black level.
