Body-size image
Copy-paste text

Make the "okuzuke" (奥付, colophon) page that goes at the end of a Japanese doujinshi by simply filling in template fields. The colophon shows who published the book and how to reach them, and is also expected for resale or consignment (BOOTH, doujin shops). Enter the book title; publication date (e.g. a date, event name, or first/second printing); circle name; author / pen name; contact (X, pixiv, email — multiple lines allowed); printer; and notices (such as a ban on unauthorized reproduction). As you type, two outputs update at once. One is copy-paste text — one button copies it so you can paste it into Word, Google Docs, a novel's body text, or an existing template. The other is a body-size image: pick a page size — A5 (148×210mm), B5 (182×257mm), A6 (105×148mm), shinsho (103×182mm) — and a print resolution (300/350/600 dpi), and export the colophon as a one-page PNG. Manga and illustration artists can load this PNG into a Clip Studio Paint or Photoshop manuscript layer and place it on the final page, or print it at full size. You can adjust the text position (top / middle / bottom), text size, text and background color, and an optional border box, and long lines wrap to the page width automatically. The title is set slightly larger and notices slightly smaller so it reads like a real colophon. Filling in, typesetting, copying text, exporting the image, and printing all happen entirely inside your browser; the personal information you enter (such as contact details) and the image are never uploaded, stored, or sent to a server. Confirm the exact notice wording and any rights statements for fan works yourself, according to your genre and the rules of your event or shop.

How to use

  1. Fill in the title, publication date, circle name, author, contact, printer, and notice fields (empty fields are left out).
  2. Choose a body page size (A5 / B5 / A6 / shinsho) and resolution (dpi), plus text position and border.
  3. Click Copy to paste the text into Word / Clip Studio, or Download PNG to save the body-size colophon image (you can also print). Your input is never uploaded.

FAQ

Is the contact info and other personal data I enter sent to a server?

No. Filling in fields, assembling the text, exporting the image, copying, and printing all run entirely inside your browser. The content you enter (contact details, circle name, etc.) and the image are never uploaded, stored, or sent to a server.

What is the difference between the copy-paste text and the image?

The copy-paste text is handy when you want to paste the colophon as text into Word, Google Docs, a novel's body, or an existing template. The body-size PNG is for placing the colophon as an image on the final page of a manga / illustration manuscript in Clip Studio or Photoshop, or for printing at full size. Both are generated at once, so use whichever you need.

Which body sizes are supported?

Presets cover A5 (148×210mm), B5 (182×257mm), A6 (105×148mm), shinsho (103×182mm), B6, and A4, with print resolutions of 300/350/600 dpi. The PNG is exported at the pixel size of your chosen size × dpi, so it overlays cleanly on a print-ready manuscript. Confirm the final trim size against your printer's spec.

What should the colophon include, and what notice wording should I use?

It usually lists the title, publication date, publisher (circle name / pen name), contact, and printer. Notices often include a line banning unauthorized reproduction; for fan works you may add a statement that the book is unofficial and not affiliated with the original, or an age restriction. The required fields and wording vary by genre, event, and shop (BOOTH, doujin stores), so confirm them yourself — this tool only formats your input and does not give legal advice.
