Review: SketchINK waterproof fountain pen ink by Rohrer and Klingner

Hi Teoh! I saw your other ink reviews and have been looking for a waterproof ink brand to use with brush pens...how does this ink perform with refilling them? Is there any danger of clogging? Or how does it compare to the other 3 you recommended? Nice review!!

Is Sketch Ink clog your fountain pen??

Great then I'll try it thanks

Recently bought SketchINK, Kakuno fp and CON70 ink converter. Love all 3 but having ink flow problems. I sketch daily and stand pen cap facing down in a jar when not in use. It takes quite awhile next day before ink will flow. If I sketch with pen, paint, then try to use the pen to date the sketch, ink doesn't flow. Have washed pen and converter twice although haven't taken the nib section apart. Am trying CON40 converter which is smaller and has ball bearings. Am wondering if I can try anything else.

Yes it seems dry up after a short time (ie 1/2 hour). Am not in a dry climate. Pen is working better today after I left it on it's side rather than nib down. Weird. Am also swishing the ink bottle around before filling the pen in case particles are settling.

Hi ! I bought a few days ago the black SketchInk and a Lami AL-STAR fountain pen with extrafine (EF) nib and Z28 converter as deposit for ink; it work beautifully ! I have leave the fountain pen with the ink for one day and the next day worked perfectly. I repeated that day and the next day also worked perfectly. That last day I cleaned the fountain pen, just in case, because I don't go to use it right now. I store my fountain pen horizontally, but maybe that is not important. Cheers !

I bought into the whole R&K Sketch Ink package only to be a little bit disappointed with some of the colours in the range.
My issue lies particularly with the absence of a straightforward Red and the Greens are also problematic.
The closest red value in the range is the R&K Jule bottle which, is rather murky and like the Greens, resolves on various watercolor papers with a very denatured finish.
Aside from developing a visual accent peculiar to the Sketch Ink range, it's a bit withering that I had to revert to deAtramentis document ink for a straightforward primary Red.
Who makes pigmented ink without the inclusion of the basic primaries!?
Apparently R & K does! Why?
The R&K Sketch Ink Yellow is very biased to the orange spectrum but can be managed thro' successive dilution but this process, aside from the tedium, uses up wells in the mixing palettes.
Anyway, that's some of my ob's to date.

Hello Teoh. I would like to ask if you know how these compare to the drawing inks by the same company?

Hi Teoh! I love your blog and work. What sort of paper do you recommend to use with waterproof inks?

I bought the SketchINK Lotte since so many say its very fast drying and waterproof; however after testing, the only paper where it acted (mostly) waterproof was regular copy paper. Some of the paper I tested with included: Arches 300 gsm watercolor (one of the worst offenders!), Moleskin Art and Moleskin watercolor sketchbooks, Canson Mixed Media, and some other drawing papers. I waited a few minutes for the first tests and then an hour for the second with no difference.

Copy paper isn't ideal because I can't use watercolor over the top of a sketch. Any recommendations? Or is my ink possibly defective/not truly waterproof?

Hi Teoh, I saw your review with the Pelikan Classic M200 and also this R&K waterproof sketch ink. Thank you so much for showing these products! I have a question about the cleaning of the fountain pen using the R&K waterproof ink. What would you recommend? Rohrer & Klingner also have a fountain pen cleaner, but I'm not sure if I will damage the plastic of the Classic M200 cognac I have. Thanks for your answer!

Thanks for your quick answer. How do you clean your Pelikan fountain pens? With water only? I'm asking because the nib is not removable from the feed as far I know it well. So I'm not sure if water can also remove the R&K ink between those parts.

I use Rohrer & Klingner sketchINK in Twsbi Go pens
I have four pens with different nibs with different ink colors
The inks are excellent for watercoloring, dry well and fast, and have a strong enough color to show thru if the watercolor is transparent
The are also strong enough to ink after painting
I leave the inks in the pens for weeks on end and have no problem with drying out, and the pens start up immediately
I recomend the inks and their range of colors

Hi! One problem you may have isn’t that you should never keep your fountain pen, pen cap facing down the pen cap should always be facing up in order to avoid ink accumulation in the nip causing it to dry

Have you tried mixing colours to create your own tonalities?
I recently asked for a sepia on a shop and the ink I received was a relatively clear brown. I was disapointed at first but then mixed gradually with black until I got to dark sepia I wanted.
