Sakura Pigma Micron vs Pilot DR Drawing Pen

Recently I was able to purchase a few technical pens. Namely four Sakura Pigma Micros and four Pilot DR Drawing Pens. The Microns I obtained locally but the DRs I bought from JetPens, though JetPens also sells the Microns. I purchased only the smallest 4 nibs available: #005 (0.20mm), #01 (0.25mm), #02 (0.30mm) and #03 (0.35mm). I have no use or desire for the larger sizes.

Both pens are of the plastic covered pourous material type, commenly called "felt tiped" pens. Both have a long metel tips that measure approximately 5mm long. The long tips are so the pens can ride up next to drafting instruments such as sliding squares and triangles as the primary use for these pens is mechanical drawing and drafting. However I, and many others, use them mainly for writing, drawing with them is secondary. I rather like technical pens for writing for they are generally smoother writing than any rollerball/gel pens. The porour tips are a bit more fragile than the metal ball of a of a gel pen or a rollerball but as long as they are treated right they should last the life of the pen.

For this test I used what has now become my standard pen test. I write a short line with it, in order to get the "feel" of the pen. I then draw a short line, later to be used for the water test, then I lightly hold the pen to the paper for 10 seconds for the bleed test. The water test consists of me placing a single drop of water from an eye dropper on each line. I do not smear the ink, I simply allow the water to soak into the paper to see if the ink will run, or "feather". After the paper had dried I scanned it and posted the results here.

The results pretty much speak for themselves. The lines produced by each pen of the same point size are relatively the same width. The second #03 pen test for line width was because the Sakura seemed to have been wider than the Pilot so I wanted to be sure. The subsequent test proved the widths to be the same. The water test showed that the ink from both pens is waterproof, which is to be expected since both inks are pigmented. There was no feathering or running of the ink iwith either pen. They are also light fast and at least the Pigma Micron is acid-free. The bleed test showed that all the pens bled through to the second page with only the #03 DR bleeding through to the third page but you had to look carefully in order to see the mark. The DRs were scratchier, in every point size, than the Microns, especially the #005 point size. The ink from both appears to be dark, not watery. The DRs are just slightly longer than the Microns and weigh about the same but I like the feel of the Microns better than the DRs.

Both pens are available from JetPens.com, the Microns for $2.00 each and the DRs for $2.50 each. As far as I am concerned my money is on the Sakura Pigma Microns.

Many thanks to JetPens for the use of the pen photos.
