Welcome to Caps On Fire / Cosmos Ink. First off, I want to say thank you for showing interest in our "Pigment Ink Conversion Kit". I highly appreciate your support and would like to express my gratitude.  

So.......you're interested in turning your existing Epson Workforce Printer into a Pigment Ink Printing Workhorse!!! Well here you have it!! This is one of the key components your MUST HAVE for your existing printer. Although the OEM ink that comes with your printer is pigment ink, your initial cartridges are whats called "Starter Cartridges". This means that they will have a significantly less amount of ink in them that the OEM cartridges you would purchase from the store. Even then, the store bought cartridges are non-refillable; so every time you run out of ink, you'll be spending $40-$50 for more cartridges. So to make things more budget-friendly, we have released our own line of pigment ink accompanied with refillable cartridges. This will save you A LOT of money as you can refill your cyan, magenta, and yellow cartridges 8-9 times, and your black 2 times (due to the cartridge being 4x bigger than your other cartridges)!! Also, our inks are developed to work with your pre-existing color profiles that were already installed on your computer when you installed your Epson WF Printer. 

What's Pigment Ink Used For?

Although pigment ink is used for regular printing, it can be applied to various methods of custom printing:

Church-style Fans

Chip Bags

Waterslide Paper for Tumblers

Inkjet Heat Transfer Paper like:

  • 3G Jet Opaque (for dark colored 100% cotton garments)
  • Jet-Opaque II - (for dark colored 100% cotton, 100% polyester, and cotton/poly blended garments)
  • Jet Pro Soft Stretch (for light colored 100% cotton, 100% polyester, and cotton/poly blended garments)(incredibly thin layer which is NEARLY self-weeding and gets softer after washing)

cosmos pigment ink and cartridge kit

easy to install, easy to fill, best color pop ive ever seen

EJR (San Antonio, US)
Pigment Ink

I am not certain this is the ink for me. I have to print several sheets before the ink is really a true ink color. Not sure why if it is pigment ink.

DAWN DAYE (Queens, US)
The best period!!!!

I absolutely love the pigment ink, I don’t know why I waited so long to try it because I was already using the Sublimination ink and loved it, But OMG, there is nothing else to say but COSMOS IS THE BEST!!!!!

Odila Kaywood (Alexander, US)
The Best!!

I have 2 WF 7720 and a 7710 . They all have Cosmos ink! One 7720 is for Cosmos pigment ink, one is for Cosmos florescent sublimation and the 7710 is for Cosmos and Regular sublimation ink. I use Cosmos for the clarity of the pictures, colors that always pop and less machine maintenance!! Love, love Cosmos Ink.🥰

Shelia Green (Detroit, US)
Fast shipping, full bottles but.....

Hmmm where do I start, my package arrived on time the colors are really bright I was excited filling the color cartridges thinking about how much better my party favors were going to look however I couldn’t get the black ink cartridge to fill. It doesn’t come with instructions so I watched YouTube videos which didn’t help because it’s not the same cartridge that was shipped. Moving on none of that mattered because I have a WF7820 not a 7720 like I thought so it’s no way I could use the ink anyway. So now I’m patiently waiting until 812/812xl compatible cartridges become available or I figure out a way to refill my espon cartridge with cosmo ink. So 4 stars only because I couldn’t fill the black cartridge

Ina Castro (Bakersfield, US)
