In the past I've mentioned the "stuff" I use for drawing, but wasn't sure whether it's of interest to anyone, then I stumbled on a whole podcast about pens - 70 Decibels network "the pen addict" ... so I figure it's probably ok.
For years I used a trusty set of Rotring Isograph pens, for pretty much everything, but I used to have trouble when I had tight timelines on illustration jobs, as unless you let the ink dry really well it'll bleed when colouring.
So I switched to using Staedtler pigment liners, which are really stable, don't bleed, and are reasonably quick. The downside is I go through them at a fair rate, and there is a long period when there's too much life in them to throw them out, but not enough to do the job properly.
For this years 24HCD I'm going to try some pens I've been after for a fair while - COPIC liners, and Micron pigment liners.
They both produce good stable lines, and don't bleed.
I have a pack of Staedtler pigment liners as a back up in case I can't get on with them, but first impressions are very favourable.
I'm not sure whether I should fill blacks with DELETER ink and brush, COPIC markers, or in Photoshop.
Likewise with lettering, I'm happy to hand letter, but it may be faster to pick that up in Photoshop.
