The Ink You Use REALLY Makes a Diffference

This is the best ink I have ever put in my fountain pens.  I had no idea until I switched to this ink what I was missing.  This ink flows very very smoothly from the pen and makes very nice black writing.  I hate blue ink.  I have been using ink refill cartridges for many years, but never again.  Only the Noodler's for me from now on.

I only recently started using fountain pens for daily uses when I was given some by a friend.  They handed me from LAMY safari pens and some inks from Mont Blanc and PILOT iroshizuku series but since the pens were LAMY I though I should give it a try too.  The colour and packaging is awesome, but outcome wasn't as pleasing.  There were two things I was disappointed with.  One, it wasn't as smooth as the PILOT ink.(This could be because I was using it on a F pen when the other was M) and two, it was too pale.  The colour was very nice and sharp, but when it got on paper, it was just too pale.  It was very hard to read.  It could be better read if written slowly so more ink comes out, but then it looses it's sharpness.  So, instead of using it to write l like I do with my other inks, I use it as a highlighter, outliner or just for keywords.  It is sharp and the words stand out.

This ink will dry in your printer heads if you do not use your printer regularly and it is a PAIN to clean them out... you essentially have to run alcohol through the printer to clear the print clogs else your picture colors will be all pink (depending on which color is clogged). I do not recommend this to someone who doesn't print more than twice a week.

Printer is ok, but it uses ink like crazy!! Don't let it stand a while, it will make you replace the ink.

I didn't use these ink pads in the traditional way.  I used them to highlight dimensional lines that I put into the latest piece of artwork I did.  Instead of just raised lines, I got them to stand out in color.

This is a review of the 4-pack, which includes Pink Pop, Lime Light, Bright Blue Bliss and Charming Purple colored pens.

Nice pens, not great, but definitely the selling point is the ink.  First of all, I love pens and have a zillion of all kinds and all colors and shapes.  My every-day, go-to pen, however, is the Pilot G2 with purple ink.  The main problem with the G2 is that the ink takes time to dry, ranging from a second or two on up  way up, depending on how slick the writing surface is.  So smears and smudges can be a problem with the G2.

The ink in these new InkJoy pens has a comparable appearance to the G2, but the InkJoy dries significantly faster.  I did some side-by-side comparisons, and the difference was amazing.  I could not get the InkJoy to smear at all on many surfaces.  It will still smear on a glossy paper if you touch it immediately, although it does smear less than a G2.

I have purchased InkJoy pens in the past and had a lot of trouble with the click mechanisms.  They were garbage; after limited use, many could not be retracted without pushing on the point.  These new pens have a nice, solid click to them, so definitely an improvement.

The grip of the pens is a bit too wide for comfort for my hands.  There is no taper to them at all.  Thats a mistake.  They should narrow a bit at the grip.  Out of curiosity, I put an InkJoy cartridge into a G2 pen, and it worked.

The InkJoy colors are great, really vivid and rich, except for the purple.  The Pink Pop. Bright Blue Bliss and Lime Light are aptly named.  The Charming Purple, lacks charisma.  It is very, very dark, and at a glance, looks almost black.  I use purple ink for the majority of my writing, and I want my purple ink to look purple.  If PaperMate ramps up that purple a bit, this set could be a real winner.  The Wild Berry color was not in this pack; perhaps it would make me happy.

I saw no glops or blobs from the InkJoy.

So all, in all, good pens, better ink.  Fewer smears, no blobs, a bit large in the grip for my tastes, but probably suitable for many people.  The colors are good except the purple lacks pizzazz.

The Hp printer doesn't not like the off brand ink. I did have to print a lot of item in color so my color ink ran out fast after it was gone my printer would not let me use the black ink. I don't think I got the full value of this item.

The ink is too bold/dark for double sided papers. It's hard to read one side because the other side is too visible. (I know I'm using the right paper)

good color transfer using dye sublimation ink on cotton

I bought these for coloring and initially liked them, but ultimately bought something else instead.

The good: ink and fine point are great for coloring

The bad:
- Cap colors are very off from the actual ink colors
- Outside of pen isn't round. It has a hexagonal shape with very hard corners. It hurts my fingers to use them for more than 15-20 minutes due to the shape.

a good color. something different. the flow seems a bit slow on most pens i tested on.
but all in all....a very good ink.

the colour seems to differ on paper when compared with scans. Just a heads up
note:this washes away with water. not a bulletproof ink.

My printer prints fine with other ink cartridges, but these don't align very well, and they bleed a bit.

I bought these to see if I would enjoy coloring. When they work - they work great. Some pens felt a little dry and the ink came out sparingly. Not a fan of the blended colors. After I subtracted the blended colors and the duplicates there wasn't much of a color pallet. Turns out every set has duplicates. Still they were cheap enough and I'm not sorry I bought them.

Pros:
1. It's black ink, and it prints black.
2. It's compatible with the Epson printers, being an Epson cartridge.
3. It's easy to change the cartridge.

Cons:
1. Epson can leave a lot of ink in the cartridge when it declares that the cartridge must be changed.
2. Epson designed this ink to favor it's "vividness" over longevity. The inks are water soluble. So if you spill your coffee on the page, the inks run everywhere. If you were to take a photo to a very humid environment, the same thing would happen. The pages don't last long.
3. The ink bleeds terribly on plain paper resulting in a very blurry print. It's obviously not a laserjet but still very blurry for an inkjet.
4. Printing a photo is expensive compared to online or local print shops. This is generally true of all inkjets compared to Snapfish, Walgreens, Flickr, CVS, etc.

I would not have bought the printer in the first place had I know Con #2, but, as long as I have it, this is the ink to buy.

This ink have very slight color in black
its actually a light color of grey
the fountain pen always cant write because of this ink have too much dense and I think this ink have old fashioned ink oil inside(means this ink is designed for feather pen)
and it dries very fast in my fountain pen
I have a montblanc fountain pen and this ink seems good because of the brand but it really sucks
I recommend ink from pilot and montblac. I purchased both blue in different brand but in same color
although it cost 20~22 per bottle but it worth to buy from pilot or montblanc

if you have a fountain pen that means you really not short on money
dont waste this money on this and have better ink
your fountain pen definately worth more than that

learned my lesson; only use the inks recommended by product; if copies/prints are coming out with pink tint...you are using substitute inks

I recently wrote a bad review for this, I want to apologize.  It was the settings on my printer that was the problem, not the ink.  I just wanted to set the record straight.
Thanks!
