Two years ago my father gave me his set of Isograph Rotrings as a gift which he bought in the seventies (of the last century lol) and used it for about 10 years... I cleaned them all and used them for a while and I absolutely adore them. but I must say... dear God the company never even changed anything in the pen. Not even the colour
I've been using those since late nineties and they still work. One advice though: don't dismantle isographs smaller than .35 completely, because the needle is REALLY thin. I had to buy another .18 isograph just because I couldn't thread the needle back in.
I like the Isograph, although I prefer the simpler Micronorm and Variant pens. If you find an old Isograph that is full of dried ink, be aware that Rotring does not recommend removal of the Isograph's inner needle for cleaning. However, after a bit of soaking, the inner needle should come out and go back in easily if the pen is 0.35mm or bigger. But it's nearly impossible to replace the needle on a 0.13mm pen, it will probably break or bend rather go back into the tiny metal tube that forms the tip of the pen.
Thanks to your video I managed to fix my old Rotring Isograph (0.3) that I thought was beyond repair. I didn’t know I could take out the inner needle; it just needed some cleaning up. Thank you so much!
NO WAAAY! I have my isographs for more than 10 years and i didn't know they can be fully dismantled. This would have spared me soo much trouble cleaning them, and certainly will from now on. thx
As a former architectural student, I found these pens very frustratingly fussy to deal with. They jam easily and require cleaning, which is very messy. You cannot use them with any rapidity, paradoxically. They should never be used on soft paper, as the steel tip will cut into the paper, ruining the drawing and jamming the pen. On the plus side, they make a perfect, even, black line, and can be used with straight edges and compasses. And they tolerate permanent ink ok, though it adds to the need for constant cleaning. When my friend the architect was using these, decades ago, he never left ink in them for more than a week, then drained and cleaned them and stored them empty. This is a great idea; and if you have to use them, highly recommended. Personally I can't deal with pens at all; I draw with graphite in a mechanical pencil, or charcoal, usually "Nero" charcoal, which has oil embedded in it to greatly reduce the production of dust all the hell over the place. Were I to use a pen again, it would be a micron. Teoh, do you have a video that explains why you draw with a fountain pen? I find them more trouble than they are worth, so I wonder why you like them. Thanks, CXC
It really depends on the inks you use in these pens. Nowadays there are waterproof inks that you can use in such pens with minimal chance of clogging. The reason to use such pens is they are durable so you don’t have to keep on buying disposable pens, more economical because ink in bottles are cheap. For technical pens like the Rotring or Koh I Noor, there are more line widths you can choose from than fountain pens. Fountain pen nibs are smoother and work better on paper compared to technical pens which has to be held more upright.
Thank you. Many questions: can you draw on any rough paper? Can you hold at any angle or you need to hold vertically? Can you use normal ink ? Thank you
Hi, Teoh I cannot find the link to the blunt needle and syringe and need to refill my pens. BTW your utube presentations on how to clean the rapidograph pens and identifying the difference between rapidograph and isograph are of very high quality. thank you very much.
Hola necesito ayuda urgente Quiero comprarme los rotring rapidograph pero quiero saber si los recargo con tinta y jeringa como lo haces tú quiero saber si voy a tener problemas con el funcionamiento ya que los rapidograph están diseñados para el cartucho y no para el rellenado de tinta
You always have such helpful and thorough videos! Thank you for creating & sharing them. I have a question though. How long can it sit before clogging and is there a difference between frequency of clogs between the isograph and rapidograph inks? I have read/watched different sources say that anything over a week and there could be a clog. A source said that the finer nibs should be cleaned after every use. Another source said that rapidographs (because its a capillary cartridge) can sit around longer than isographs without clogging. Ahhh! there just seems to be so much information for a pen. I guess that I'm also worried about having to draw with the pen vertical and the finer point catching on any surface that isn't hot-press/vellum.
I do not see the link you referred to for the syringe you are using. Can you please update your description section to include said link, please? Thanks!
Has any one had luck using Koh-I-Noor's in size 0.18 and 0.13? I bought them and returned them because one barely worked, and the other one didn't at all. Im guessing the cleaning pump tool could suck them working again. But I use Rotring Rapidiograph 0.18 and 0.13 as a replacement for these sizes. They work better because the ink that Rapidographs use isn't really waterproof and is less clogging. Also Radiograph lines are a bit thicker then Koh-I-Noor, Isograph lines are thicker then Rapidograph I heard. I like Koh-I-Noors the most, but I have only tried one size of the Isograph.
I'm using Staedtler Marsmatic technical pens (less well-known than Iso/Rapidographs, but worth checking out, I really enjoy them, they're simpler in construction than Rotrings). I do use them with Rotring ink, but in my experience that ink isn't waterproof on most papers... though it should be. Does anyone have a suggestion for a good ink that's nice and black and fully waterproof?
Rotring sells a "drawing ink" bottle that is waterproof ink. Rotring Rapidograph Cartridge ink isn't fully water proof. They did this so that the pens wouldn't clog as easily. However, I would still recommend using Rotring Cartridge ink for Rapidograph sizes 0.13 and 0.18 so that they wont clog as easily.
Hello Teoh, I'm thinking in re-use my old Isograph. Is it possible to refill it with fountain pen ink? what about Platinum Carbon ink? Do you think it would work? Thank you
+Jesús Guerra Martín It should have no problem with Platinum Carbon Ink. But there is no advantage of the Platinum Carbon Ink over Rotring Ink which is cheaper.

Thank you Teoh Yi Chie, I use two or three different instruments in the same drawing, and I prefer use the same ink in all of them, so there is not different kind of black.
Hello Teoh, Could you tell me what the difference is between these Rotring pens and Faber Castell Pitt pens or Sakura Microns? Thanks and a happy new year!
Thanks for your answer Teoh! Do you think there's any difference as far as color intensity or ink flow goes? I use the Pitt Pens and the Microns on cold press watercolor paper and the ink flow is pretty irregular (because of the paper's bumpiness I think). Thanks a lot for your videos, they're very informative!
+Smbat B. For ink flow, paper matters. Technical pens work well on smooth paper. To get better ink flow, you have to draw more slowly to allow the ink to flow. It is just the way the pens are designed, they are not meant for quick sketching.
You can use the Rapidograph body with the Isograph grip section but not the other way round. The Rapidograph body has an emptier body because it needs to hold the longer ink cartridge.
do they can swap their pen nibs? i can find pen nibs for rapidograph in my country, but not isograph. but i also heard that isograph is more easily refillable, so i want to know if they can replace with other’s pen nib.
@@teohyc thanks for fast reply. fortunately i find really cheap isograph bundle(0.18+0.35) with 8$. at that price i really can't grump about pen nibs. :D
Hi What type of inks should be use in the isograph pen? Or do the makers recomend a certain brand? Thanks for this informative video. Cheers frm Australia.:)
Well we need to see how your other pen does work by the same brand (the one in the box). a nice drawing comparison using the 3 pens. this one was a nice video explanation. thank you Teoh as always. I like your videos a lot, I'm older than you btw.
HI Teoh, I have been using an isograph pen since high school (for drawing & writing) and I always use the Rotring ink for it. can we use other type of ink in it (ie, India ink, Fountain pen ink, etc), I mean that I have never tried anything other than the Rotring ink. thanks
+Elga Benedicta Rotring ink is waterproof so there is not much reason to use other pigmented inks like the India inks. It can take fountain pen inks too if you require other colours.
@@teohyc The ink in rapidograph cartrages feels only semi-waterproof where as "rotring drawing ink" feels 100% waterproof. I contacted rotring about this and they confirmed that the rapidograph cartridge ink is slightly different due to its more technical feeding mechanism.
Thanks as always, Teoh. So why would you use this type of pen as opposed to a Micron of the same size? Is it the consistency of the thickness of the line?
Well, you can use bottled ink. The ink is far less expensive and far blacker, and it's possible to get a wide range of colors, too. Plus they come in many more sizes. I actually have a 2.0mm! The sizes are the actual line width, not the tip measurement. The most annoying part about Microns is that they start off relatively black but get weaker and weaker as they are used up (because they contain a sponge saturated with ink). If I used a disposable drawing pen I'd go with the Rotring Tikky Graphic or perhaps the Ohto Graphic Liner; their liquid ink reservoir means they have the same dark black from beginning to end.
raosprid Thanks! This is very helpful. As a newbie, markers serve my purpose for now. But I can see the advantages of these Rotring pens in the future.
+Gary Gentile This is more durable because of the metal tip. But when the pen gets dirty, during refilling, you need to clean it. I prefer this to disposable pens.
From Sakura website: Sakura invented Microns as an inexpensive and disposable alternative to high-priced technical pens while maintaining technical-pen quality.
Writing / drawing is not the same - rapidograph nibs are softer more suitable for drawing and sketching ( they wear out ) , isograph nibs are much harder more suited to drafting paper / hard smooth paper, not suited for sketching on cartridge type papers or even Bristol boards as the hardness of the nib seriously rips softer paper and the lines are very scratchy
4:13 i never knew that...clearly the school have never thought me that. now i feel bad on my pens for misplacing them. and they're hard to find in the house,plus they're pricey :(
@Kelvin Guru it’s the Eighties no internet or YT to see how you clean those pens properly. Me back then 13 years old has no clue how to maintain these pens, that was the point of my answer, school lets you buy these expensive pens for technical drawings, they should have learned students also how to keep them properly working, because they are not cheap.
@Kelvin Guru i have a new box of these pens and surprise, surprise no manual, and these pens were bought at school, not at a store, mister self righteous know it all, that thinks how other people spent their time. And how many 13 year olds you think that these pens needed maintenance, if no one mentioning it? Nobody in my class or school did, and I once dissembled a pen, took the needle out and bended it after cleaning it and putting back together, too find out later you don’t take the needle out of the small pens, but no one told me back then as 14 and 15year old when some of these pens started to clog and forming a ink bubble on its tip. Not everybody is a self righteous prik like you, that thinks he knows it all because of the access to internet these days, but probably you walk with your head to much in the clouds to know that in the eighties their was no RUclips or internet in households. Don’t you need to be on Twitter? All the human self righteous pricks spent their time over there thinking they know it always better then the rest.
I loved my rapidograph, until it stopped working, i had the 0.25mm version and would use it for illustrations. However it always took a while to get the ink flowing and one time after not using it for 3 days or so i could not get it to start at all. I put it in water to maybe soak the ink out as this had worked before, but no luck. Next i even bought the rotring cleaning fluid and even this didn't work. Somehow i've got a bad feeling that there is dry ink stuck in the needle which is almost impossible to get out. I feel like these pens are very high maintenance, and mine only lasted 6 months because i cant get it to work again, which is very disappointing. But i can say that no other pens i've used compare to the quality and detail these will give you... even so that i would risk buying another, with maybe a larger nib to make cleaning easier.
These pens look so technical and scary. I will never buy them until I see someone else talking about it. Might consider though it still looks troublesome.
I had a Koh I Noor rapidograph... what a nightmare. Used it for a few weeks 3 years ago and it has worked since after numerous cleaning attempts. Tech pens aren't for the younger crowd, I stick to the micron and staedtler pens. Same results without all the time wasted on cleaning and ink splashed all over the place lol smh
The trick is, that you have to spend an extra hundred dollars on cleaning kit pumps and ultrasonic cleaners to keep them working good. If you don't, good luck. Also, non water proof ink, such as in the Rotring Rapidograph cartridge ink will make them not clog as easily. Definitely recommended for the smaller sizes.
The main issue I have with the isograph is that I fear that the cartridge could fall off while keeping the pen in a pocket or carrying it around, for example. It just doesn't seem to have a safe grip to me.
Two years ago my father gave me his set of Isograph Rotrings as a gift which he bought in the seventies (of the last century lol) and used it for about 10 years...

@@teohyc Why you have to hold this pen vertically to draw? as i saw in many videos. Thanks for the video!
@@Sketcher86 Rahul Kumar I find the lines more consistent and predictable. You can tilt the pen to draw too.
@@Sketcher86 It uses gravity for ink/air balance in the channel.

The trick is, that you have to spend an extra hundred dollars on cleaning kit pumps and ultrasonic cleaners to keep them working good. If you don't, good luck. Also, non water proof ink, such as in the Rotring Rapidograph cartridge ink will make them not clog as easily. Definitely recommended for the smaller sizes.
The main issue I have with the isograph is that I fear that the cartridge could fall off while keeping the pen in a pocket or carrying it around, for example. It just doesn't seem to have a safe grip to me.
+Jacopo Moruzzi The fit is very tight. I doubt it will fall off.
I have rotring 2000 isograph
and isograph have many ink colour varieties ;)
+CrystallLine 515 Each line weight has a different colour for the grip section if I am not wrong.
They were reffering to the different coloured inks available for using with Isograph pens.
But if you refill the rapidograph cartridge with other color ink you have the same amounts of color inks
Microns for life........
I clean my rapidos with mentholated spirits
PLEASE not Menthol! It's Metholated spirits (the blue bottled stuff)
It's methylated spirits, as in methyl alcohol.
Amazing tools
