Since Copic markers are an alcohol-based dye ink, they require a certain type of ink to be compatible when coloring rubber stamped images. For instance, Tsukineko's Staz-On ink is usually permanent on just about any surface but the alcohol in Copics react to the solvent in Staz-On and basically reactivate the dried Staz-On and will smear an image stamped with it:
The scribble of pink under the marker tip is the color the marker is supposed to be. See how the marker reacts with the Staz-On stamped sleeves and smears them?
Following are a few different ink options that work well with Copics.
My all-time favorite ink to use with Copics is Tsukineko's dye-based Memento Tuxedo Black ink pad. It stamps crisp, clean and clear, dries very quickly and a stamped image can be colored immediately after stamping, with no smearing:
Above are examples of coloring a Memento stamped image (upper left) immediately after stamping, (upper right) 30 seconds after stamping, and (bottom) one minute after stamping.
Below are the results of using Copic's Colorless Blender, repeatedly rubbing over the stamped lines of the apron's neckstrings (right where the marker tip is pointing):
The Blender was rubbed repeated over the black stamped lines and never smeared. This ink performed excellent on all the tests.
Next is Ranger's Adirondack Pitch Black dye-based ink pad. It also stamps crisp, clean and clear but generally needs just a little bit longer to dry well on its own.
The same coloring tests were performed -- immediately after stamping, 30 seconds after stamping, and one minute after stamping:
My apologies for the blurriness at the top of the photo, but hopefully if you click on the photo for a closer look, you'll see a little smearing on the top left sleeve (immediately after stamping). But as the ink dried on its own, you'll see it performed well under normal coloring circumstances.
But the Blender marker test left a little smearing of the stamped neckstrings (click for a closer view):
Keep in mind, the Blender marker was rubbed repeatedly over the stamped lines, so under normal coloring circumstances, you probably wouldn't experience this problem.
I also tried heat setting the Adirondack ink for 30 seconds and then waited for 10-15 minutes before coloring the stamped image, with improved coloring results:
Bleeding with the Blender test was also improved:
Lastly, I tested Tsukineko's Brilliance Graphite Black pigment ink pad. This is the ink I used to use all the time with my Copics, before Tsukineko came out with their Memento line of ink. Because it is pigment-based, you will need to let this ink dry thoroughly before coloring it, or quickly heat set it. In my test, I let the stamped image air dry for about an hour, with these results:
Same crisp, clear and clean stamped image and no bleeding of the stamped lines when Copic marker was applied over the ink. Remember, I colored outside of the lines on the left sleeve for testing purposes below (wink)
This ink also performed excellently, even after repeated rubbing with the Blender marker to remove the pink marker on the neckstring.
I hope that gives you some ink options to keep in mind when coloring with your Copics! Below is a little eye candy I made with one of these stamped Lockhart Vintage Aprons, combining it with the more masculine/less frilly Apron:
