Those who have known me for a while also know that I enjoy drawing and sketching and have for as long as I can remember. I have always been a pencil artist, although in the last couple of years, I have begun to use pens and markers as well. I was partial to the Letraset Tria markers for a while, until I was introduced to Copic markers. These markers share several similarities with other brands, including dual tips (one on each end) and colour-matched, alcohol-based inks.
If you have never used illustrator's markers, you might be in for a surprise. First of all, the pigment density of these markers is far higher than anything else you might have tried. Secondly, these markers can provide very even coverage, but to achieve this, one must be quite skilled, and most of all, quick! These markers are wet!!!
Copic makes several lines of markers, although only two lines can really be considered as illustrator markers, the Original and the Sketch. The Original is a square bodied, dual tip marker, usually sold with a chisel tip and a fine line tip. These markers are garanteed to not dry out for a period of three years (this is one of my main complaints against the Tria brand). The Sketch markers have an oval body and share the dual tip configuration, although these are usually chisel and brush point tips instead.
Copic markers also have replaceable tips, which means that it is now possible to change the tips if they ever become worn. These markers are also refillable from bottles of Various Ink, also made by Copic, with each bottle able to fill between 7 to 10 markers (based on the type).
The Original line features a set of 214 colours, while the Sketch line features a set of 334 colours. Take a look at the available colours from the charts, but do yourself a favour a see them in person at your local art store! Many of the colours are also available in a Wide format, with a two inch chisel tip, for broad colour application.
