Rotring Isograph Pens

Rotring Isograph Pens

Rotring Isograph Pens are technical drawing pens with a steel nib for precision drawing on drafting papers, tracing paper, vellum and lineboard. They are a popular choice with draughtsmen, architects, designers and engineers as well as artists, illustrators and students. Rotring Isograph Pens will give a constant line width and when enlarging or reducing a technical drawing plan the lines will stay to scale which is a very important factor in engineering and design. The ink can be refilled and the nibs can be replaced.

Pullingers Art Shop stock the complete range of Rotring Isograph Technical Pens along with Rotring Isograph Nibs and Rotring Isograph Ink.

What sizes are available in the Rotring Isograph Pens and Nibs?

With a wide choice of nib sizes, Rotring Isograph Pens are ideal for fine detail drawing, sketching and broader strokes. The pens and replacement nibs come in the following sizes: 0.10, 0.13, 0.18, 0.20, 0.25, 0.30, 0.35, 0.40, 0.50, 0.60, 0.70, 0.80 and 1.00.

There is also a set available which is a favourite amongst design students due to its great value. The Rotring Isograph Pen Set contains three Isograph Pens in different nib sizes, a bottle of black ink, a mechanical pencil and leads, an eraser and a compass attachment so that you can use the technical pen in a compass.

How do you refill a Rotring Isograph Pen?

The Rotring Isograph Pen has a refillable ink reservoir. Simply unscrew the pen’s barrel and remove the plastic reservoir by pulling and twisting it off the nib section. Remove any old ink by tapping the reservoir on a piece of tissue. Fill it up with your ink (not fully or it will over-flow when you push the nib section back on) and gently push it back on to the nib section. Screw the barrel back on and gently shake your pen with the lid on to get the ink flowing to the nib. Your pen is ready to use. It’s as easy as that!

The best ink to put in your Isograph Pen is the Rotring Isograph Ink which is available in black, red, blue and white. The ink can be mixed together to make your own colours and they are extremely opaque, including the white. Isograph Inks are lightfast, fast drying and waterproof. Rotring’s black technical ink gives you the densest, blackest line on the market.

How do you change the nib on a Rotring Isograph Pen?

Changing the nib on an Isograph Pen is very easy. Unscrew the pen cap on the nib and unscrew the pen barrel from the nib section. Remove the plastic ink reservoir. Get the new nib section and push the ink reservoir on to it. Screw the pen barrel back on to the nib and pull off the protective plastic cap that protects the new nib (discard this). Your Isograph Pen is now ready to use.

How do you clean a Rotring Isograph Pen after use?

You don’t have to clean your Isograph Pen after every use but we recommend that you clean your pen fairly often to avoid clogging up the nib. If you are using the very fine Isograph Nibs then you must clean them more often. Disassemble all of the pen parts and leave them to soak in warm water with a little fairy liquid. You can use Rotring’s Cleaner Fluid if the ink has really dried up your pen nib. After cleaning, rinse all of the pen parts in clean water and leave them to dry thoroughly before re-assembling your Isograph Pen.
