If you are doing black and white comic drawing or using screen tones, we suggest using the manga manuscript paper as your Copic Paper of choice. It has a very smooth surface, so even your finest Multiliner pen sizes will give you a very smooth, unbroken line. It also has printed blue guides which are great for lining up rulers, but are not conducive to coloring.
For professional product design, automotive design, architecture and landscape architecture, we recommend using the Copic Marker pads. Please note that once the ink is dry on this type of Copic Paper you can’t go back and rework it because the colorless blender does not work with the Copic Marker Pads. The Copic alcohol marker pad is similar to other brands on the market, except that the Copic Marker Pads is specially formulated to reduce speckling*.
*Speckling is caused by denser, darker parts of the tree being mixed with lighter parts during the Copic Paper making process. The different types of wood absorb ink at a different rates, causing a speckled pattern to appear.
Architects and Landscape Architects frequently use tracing Copic Paper or vellum. Higher quality tracing Copic Paper will give you better results because they have a sturdy coating that reduces speckling. Tracing Copic Paper and vellum also have the added benefit of allowing you to fix your mistakes.
Any time you use the Copic Multiliners for line art you will want to work on a Copic Paper with a very smooth surface. If you think on a microscopic level, every time you drag your pen tip across the top of the Copic Paper it's like rubbing it against sandpaper. Your pen nib, especially the finer tipped pens, will not last as long if used on a rough surfaced Copic Paper.
Additionally, rough surfaced Copic Paper will not allow you to get a clean, consistent pen line. For example, if you were to use copier paper to draw with a Multiliner, the paper fibers are going to pull your pen line thicker, so your lines will not be as precise. We see this all too often interpreted as a defect in the multiliner, when in reality it is an inappropriate choice of Copic Paper matched to the project at hand. If you like to add pressure to get a thicker line, we suggest using a few sheets of scratch paper under your work at all times to extend the life of your Multiliner. Working directly on a hard, flat surface with Copic Marker Pads may be better if you are doing more technical drawings that require a very precise, consistent line.
