The most common paper used by manga artists is Deleter Comic Book Paper. It comes in many types, but the two main types are the A and B paper. Deleter paper is size A4, so it it a bit bigger than normal copy paper.
The first type I’m going to talk about is the A paper. This paper is ruled, meaning there is a ruler on all four sides of the paper. This is very handy for ligning up panels and other details on your manga page. There are also dotted boxes for page numbers, printing cut off lines (anything outside of that line will not get printed), as well as a drawing frame. All lines are printed in light blue ink that won’t be visible when you scan the picture. This paper is available in two thicknesses: 110kg and 135kg. The 135kg paper is thicker and is less likely to get bent or crinkled as you work on your manga page, or when you store it.
The next type of paper is the B paper, which is the same size as the A paper, buy doesn’t have any of the ruling or lines that the A paper has. It is just a plain piece of paper. It is really good for drawing the splash pages of your manga and can even be used with Copic markers. I found that the Copic colors look very nice and vibrant on Deleter paper, but use the 110kg paper rather than the 135kg paper so it doesn’t absorb as much of your Copic ink.
So those are the two main types of manga paper! I like how the translation from Japanese to English on this product is so terrible! Here’s one of my favorites: “Be careful not to cut a hand at the end of a paper.” Hahaha!
