🧐 Frequently Asked Questions

Q. What is "bleed" and why do I need it?

A. Bleed is the area of your artwork that extends beyond the final trim line of the page. Since physical paper cutting is never 100% precise, the bleed ensures that there are no unprinted white edges after your pages are trimmed. Most professional printers require a bleed of 3mm to 5mm.

Q. Which DPI should I choose for my manuscript?

A. DPI stands for "Dots Per Inch" and determines the print quality. As a general rule: - 600 DPI is recommended for black and white (monochrome) line art, as it produces sharper, cleaner lines. - 350 DPI is the standard for full-color or grayscale illustrations. Using a lower DPI may result in a pixelated or blurry print.

Q. What is the "Safe Area"?

A. The safe area is the inner margin of your page where all critical content—like text, character faces, and important plot elements—should be placed. Keeping content within this zone guarantees it won't be accidentally cut off during trimming or lost in the binding process (the "gutter").

📚 Did You Know? The "B5 Doujinshi Standard"

You may have noticed that B5 is labeled as the "Doujinshi Standard." This refers to a common practice in Japan's vibrant self-publishing (doujinshi) culture. The B5 paper size (182 × 257 mm) is a Japanese Industrial Standard (JIS) that is slightly larger than A5 but smaller than A4. It became popular among artists because it provides a comfortable amount of space for drawing while being cost-effective to print and easy for readers to handle. While artists use various sizes, B5 remains the iconic and most prevalent format for doujinshi works.
