OCP K3 ink set: the secret/solution is in the ...magenta !!!

[pharmacist]

Hi Jtoolman,

Yes: the other OCP colours are excellent, but the problem is the Magenta, so I do not understand the new Vivid version is so bad....

 

[jtoolman]

It's absolutely MATTE!!! But then so are the VM from IS. At least the regular Magenta and light magenta currently included in the OCP K3 version does have some gloss. My friend is going to substitute the very excellent performing CONE V Mag and L V Mag for the OCP and after running new profiles will re test. He said all the other colors are fine.

Would work just dandy for Matte and fine arts papers but at this point it is a big FAIL for glossy - luster and satin papers.

By the way I just recieved another pint of each from our US OCP reseller, Rjettek and at 16 0z prizes I figured out that the cost is about 2.9 pennies per ML or $0.02.9

That is insanely cheap and even I we end up having to replace both the magentas for better performing choices, we would be miles ahead of the game.

I can confirm your friends finding about the other colours: all are good, except the magenta....which is actually dark red, not magenta, causing a dramatic drop in the bright blues and purples. Because for me the price of the Octopus T343 Magenta (for the R2100/R2200/Pro 7600) is the same, I have bought a bottle of this ink and the problems were gone. Excellent gamut, bright reds, purples and blues now.

FYI: I have sold my Epson Pro 3800 and updated to an Epson Pro 3880 and again purchased an I-refill system alongside with a set of the common refillable cartridges and did a test and what I have discovered the problem with the greenish ABW-mode with the older IRK4-nano is now completely gone, actually it prints now perfectly neutral (not cool or slighty warm as with the OCP K3 pigment or strong magenta, like the Inkjetfly IMA24/36 V3 with normal magenta) and the already good glossiness of the IRK4-nano is now even better. I would like Inkrepublic.com to batch their lots, so we can know which batch you ar buying. The first version causes a strange greenish cast in the ABW-mode, some clogging problem with PK, but gamut and glossiness were perfect.

Our observations were the very terrible gloss characteristics of the OCP VM and LVM ink. In fact it was totally matte. Once profiles were created it printed our test prints very well as far as color but anything red or related to red looked as if it have been sprayed with matte varnish. No gloss at all.
Does the Octopus T343 Magenta produce good glossiness? Because Image Specialists VM and LVM also does not!
So we are limited to printing on matte and fine art papers because of the lack of gloss in on any printed colors that utilize the two magenta inks.

Here in the USA we use CONE K3 VM and LVM ( Inkjetmall.com ) in lieu of the equivalent OCP ones. The gloss and color is superbly improved.
Unless any of you guys have not used CONE inks, those who have, know of their excellence and though subjective, some prefer them to OEM. However they are probably one of the most expensive 3rd party inks out there.

I will take a look at Octopus T343 Magenta ( I do have three 2200s printing on rolls in my shop ) and maybe order some but I could also get a couple of 120ml bottles of VM and LVM from Inkjetmall ( CONE ) for about $60 to replace the ailing OCP equivalents.

Thanks again!

Hi, i would need a reference to a good K3 ink to refill Epson R3000 non OEM cartridges. Any update on OCP inks?
Thanks

I was forced to eliminate ocp inks from my printers, two of them. Both have problems with yellow and matte black inkflow after printing a few meters of heavy colored images. In my 9900 i was even forced to replace the dampers.

Hi Pharmacist,

I have been testing for a few weeks now with this fantastic and very cheap refill ink made by OCP Germany.

Now the result by just substituting the OCP K3 magenta by Octopus-Office T0343 magenta is astonishing:

As you can see: the solution can be found in the magenta...

you know that I use also OCP inks and since a few days I also own a (used) R3000. I tracked your postings here month ago and now since I also have this printer and run out of inks I ordered one liter of each color OCP K3 except for the magenta where I choosed your recommendation.

I noticed your comparision with both ink sets, but now I'm wondering how these compare to the original Epson inks. Have you also compared your new OCP mix with the OEM profiles?

I also own and use a Pro 4800, currently with all OCP K3 inks. If the carts will get empty, I will try to use the new mix also with this printer.

What I am currently doing with my OCP K3 inks is substituting both Magentas with OEM! Yes OEM purchased on EBAY in 110 or 220ml carts for 4800. You would need 4880 carts for your R3000.
WHY do this?? Not just to correct the color problems with OCP magenta ( although once profiled, it's not that far off at all ) but to restore GLOSS! OCP and I.S. magenta is VERY low in gloss and will really annoy you to death. A couple of the blacks also need a bit of help as well.
Since one of my 3800s is running pure OCP K3 I only print Matte and art papers. Every couple of months I have to do a switch of the blacks to at least keep the PK line "Alive".
So for instance, on my R2400 which also uses K3 I substituted the OEM magentas and basically have a hybrid ink set just like Pharmacist. On my R2880 I subbed the OCP K3 with OEM Vivid Magentas.
Gloss is now great, not to mention color! An image of Red cars or read flowers used to look Matte, sorrounded with gloss. Yes it was that bad.
Prices for 220ml of Magenta OEM can run about $30-$50 and the ink is easily aspirated fromt eh exit port. BUT with the 3 penny per ml average cost of OCP K3 inks, it's still a huge savings.

I am using Netbit, Sihl and TPI papers and I do not experience your problem, even after 2 minutes of drying.

I know the Aldi Belgium is selling Netbit papers
Is there any other source for Netbit papers e.g. in Germany?

Hello,
can someone report the actual result for bronzing with ocp ink.
Which Color cause this Problem, is it the yellow ink or maybe the black or cyan one?
Is it possible to check it on a Colorchart for Printercalibration for example? The pure Colors bronzing should point to the real cause.
How about the Octopus Fluids inks in comparison with OCP ones, is the Yellow or cyan better in any relation?

Hope you understand my rusty English
