Well, a registered business has to make money of course (taxes are paid by the customers, I suppose). I called around a bit and got a nice offer from Inktec. The group buy is just a way to take advantage of the offer and besides that, make some other people happy. You are very welcome to try a...

Great! - 4 sets available!

It is indeed the "new Powerchrome K3", Martin. Let's see if we can get a bit more interest in this thread. - 6 sets available!

Dear fellow printergeeks, In the quest for a good replacement inkset for my Epson R3000 I decided to give Inktec's Powerchrome K3 inks a chance. Just like most of you I have difficulties finding the inks in quantities less than 1l per colour so I decided to set up a little group buy. The...

As far as I know it is the printer driver that determines all this, not the firmware of the printer. The people at Printfab do custom printer drivers. The hard part is optimizing the algorithms that determine when the extra colors should be used. I have been dreaming of converting an 8-channel...

Then it remains a questionmark why inkrepublic did this. Maybe to correct the greybalance? Well, SWOP and ISO gamuts are very small compared to what these printers so it's not a challenge for them. I was just thinking that it might make a difference in light, saturated red, green and blue...

Chroma is very similar to the saturation of a color. The higher the chroma of your inks, the wider the total colour gamut will be. With density I don't mean the amount of ink on paper here, I rather mean the pigment concentration of the inks. The light cyan and light magenta of the IRK4...

Well, the rectangles are 15 x 40mm and the I1 averages over a 5mm (eyeballed) spot. I was also concerned over this, but I did many different readings and chroma values didn't change that much. I'm not saying this is a perfect way of doing it, but I feel it's sufficient to check the chroma of an...

Using a printer is indeed impossible. Without a rip you cannot control which inks are used for which colour. The vertical stripes you see is just masking tape used to attach the cards to the glass jar. It also gave me a way to position the I1 so that I could ready the same patch for each...

No, as I couldn't measure the ozone concentration there is no way of extrapolating this to a real life situation. You can compare results inbetween the inks themselves though. I know ozone and light fading are totally different mechanisms. This test is just an ozone test, but I feel it does...

Aha, very interesting. I'm looking forward to see the results. I recently measured quite a lot of different inks and I huge differences in density of the different inks. The chroma of each of the C,M and Y inks was quite similar so I'm wondering if the huge differences in light magenta and light...

No, ozone is just one of the problems. Short wavelength light (intense blue and uv light) are also damaging pigment and dye inks. Ozone testing was just easier and I believe that it shows the relative fade resistance of the ink. I think a fade resistant ink will be more resistant to both light...

They are hosted by Imageshack. Works fine here. Anyone else having the same issue?

The quest for the perfect inkset After a long love-hate relation with my old Canon IP8500 I decided it was time for an upgrade. I wanted a machine that could take anything I throw at it and print it with perfect quality. A bit of market research revealed that the new Epson R3000 would fit the...

Can you point me to the correct place? I can't seem to find it. I do see their pigment inks though. Inkowl does mention the ink composition on their website under "what ink to choose". Anyway, I contacted the (very friendly) people at Inkowl and we discussed my needs. I explained them I would...

Can you explain this in detail please? I though every time a new cartridge was inserted all colours where flushed? This would mean that each reset of any cartridge purges all colours..or not?

I'm a bit lost with the ink(s) to choose for this printer to be honest :( I love the appearance of dye inks: superb colours, deep blacks, no gloss differential, no bronzing, no scratches in the ink... Imkowl's archival series seemed very nice but until now I haven't been able to find any data...

Well, the compatibility of inks is my biggest worry. Pigments when dilluted can drop out of suspension I think and a bunch of pigment particles together is the start of a nice clog. I'm not a chemist, so I can be wrong in this of course. The waste ink is not so much of a problem per se as...

Same questions here, especially regarding the priming procedure. Are these filled with the syringe vacuum method or would that damage the plastic foil?

I've been looking for an inkset to go with my new Epson R3000. Key features for me are wide colour gamut, high Dmax and fade resistance. The Inkowl Archival inks for the Epson R2880 (K3 inkset) promise all these features along with high gloss and no bronzing. When reading the spec sheet it seems...
