DrawBot – Pen Selection, Part II

Posted on by

I believe my next challenge, aside from better DrawBot calibration, is to find a good pen and paper combination.

This afternoon after I got back from a meeting, but before I went back to the office, I stopped off at an office supply store.  The local craft/hobby store near work didn’t have any really big rolls of butcher/craft paper – which was very disappointing.  Luckily, the office supply store had a slightly larger roll of white paper. 1

I really went there to check out the pens.  And, there were a LOT of these pens.  An entire side of one large aisle was devoted to pens.  However, since this was an office supply store, you could only buy these pens in office supply quantities for office supply amounts.  I was not about to drop $20.00 for a five pack of multi-colored pens only to find out that that style of pen just doesn’t work in a near-horizontal drawing robot kung fu grip.  I even checked out the pen refills, which were more reasonable – but the selection wasn’t there.

One thing I did while I was there was write down the name of every brand name pen manufacturer I saw.  Here’s the list I came up with:

  • BIC
  • Cross
  • Montblanc
  • Paper Mate
  • Parker Quink
  • Penatia
  • Pentel
  • Pigma
  • Pilot
  • Sharpie
  • Uni ball
  • Waterman

While I understand Montblanc and Waterman pens to be on the expensive side, I would gladly pay for a pen that “just worked.”  I would point out that the Pigma was no where to be seen at the office supply store.  This is a really nice quality art pen and I’m actually surprised I didn’t see any of them when I was at the craft/hobby story yesterday.

One other side note… while at that craft/hobby store I noticed fountain pens.  I’ve never tried to write with one, but I did wonder how effective they would be in a nearly horizontal orientation.  It could result in some very cool drawing effects.

But, for now I think I’ll focus on robot calibration for the moment while I ponder this move.  In the meantime, if you’ve got a pen suggestion, please let me know!

DrawBot – Pen Selection

Posted on by

I just tried several pens.  Here’s what I’ve found:

  • “Fine point” Sharpie, black.  This is the kind you typically use.  It makes a huge, stinky, black line that leaks all over.  Not recommended.
  • “Ultra fine point” Sharpie, black.  This also leaked right through the paper, made a super thick line, and made such a mess I stopped the drawing.  Not recommended.
  • Pilot Precise Roling Ball V7, Fine, red.  I really like this style of pen for writing.  These gel pens feed ink easily, the ball point rarely gets messed up, and it’s just all-around easy to use.  Unfortunately, as you can see from some of the drawings, it didn’t like drawing at a nearly horizontal angle.  Even though I can see through the side that the pen has sufficient ink and that it is reaching the pen tip, it just wasn’t working very well.
  • Piolot G-2 10, black.  While excellent for writing, this pen was miserable for use in a DrawBot.
  • Uni-ball Deluxe Micro, blue.  So far, this pen is AWESOME.  It seems to write amazingly well on a nearly horizontal surface, no bleeding, and it draws a very fine line of blue.  I fully intend to buy several different colors of this pen.  I believe it comes in all kinds of colors – black, blue, green, and red.  If the drawing I’m having the robot work on now turns out, you’ll get to see just how awesome this pen really is.

As an FYI, Sandy recommends:

Very smooth paper (like Bristol board) with hard-tipped fineliner pens.  In the UK he uses ZIG Millennium pens.  He suggests that Pigma MICRON pens may be a good choice for those in the states.  I’ve used Pigma Micron pens for years and really like them for pen-and-ink drawing.  They’re great on regular photocopy paper as well as serious art paper.  I would have tried a Pigma pen, but I couldn’t find any around the house.  I know I’ve got a stack of them – I just can’t find ’em.  If and when I do, I’ll update this post.
