I. The Origin and Development of Vertical Writing

1. The Origin and History of Vertical Writing

Vertical writing, also known as vertical typesetting, is a typesetting method where text is arranged from top to bottom and from right to left. It is most widely used in East Asian countries, particularly in China, Japan, and Korea, where traditionally, the writing system is vertical.

In China's oracle bone script and bronze inscriptions, the writing exhibited vertical characteristics, with characters arranged sequentially from top to bottom. Subsequent scripts such as seal script and clerical script continued to maintain the vertical tradition, and documents like bamboo slips and silk manuscripts were also predominantly vertical.

Japan's Manyogana, like Chinese characters, are arranged from top to bottom and from right to left. Many waka poems and literary works such as 'The Tale of Genji,' as well as Edo period ukiyo-e, continued to maintain vertical writing. Iconic literary works like 'The Life of an Amorous Man' were also vertically written.

2. The Application of Vertical Writing in Modern Publishing

In modern publishing, many literary works, such as novels and poetry, still play an important role in vertical writing, especially within the East Asian cultural sphere.

Moreover, in academic works and the reprinting of ancient books, vertical writing is widely used to preserve the original layout style and historical authenticity.

Modern electronic media, such as vertically written PDFs and vertically written EPUBs, allow publishers to flexibly present vertical content on both paper and digital platforms. In advertising design and art works, vertical writing is also used as a visual tool to enhance uniqueness and appeal.

II. Translation Techniques for Vertical Writing Documents

The translation and preservation of vertical writing formats in PDFs or e-books (such as vertically written EPUBs) are of significant importance for cultural heritage, academic research, and international collaboration.

For example, translating classic ancient texts like 'Dream of the Red Chamber,' preserving the vertical format of Japanese legal documents, and user guides for Japanese product manuals contribute to the protection of cultural heritage, accurate citation of academic materials, and provide a better international user experience, enabling global readers to better understand and apply these important texts while respecting the original layout style.

1. Challenges in Translating Vertically Written Documents

Complex Layout Structures

The character and line spacing of vertical text differ from horizontal text, especially in vertical PDFs (such as translated Japanese PDFs), making accurate recognition and extraction of characters and lines a significant challenge.

Additionally, documents may contain both horizontal and vertical text, increasing the complexity of detection. Some vertical PDFs also include multi-column text, which needs to be correctly identified and separated to accurately extract content.

Image Quality and Preprocessing

Vertical documents are prone to skewing, low resolution, or noise issues during scanning, requiring image preprocessing to enhance OCR effectiveness.

Vertical text requires higher demands on these preprocessing techniques because the vertical arrangement of characters is more sensitive to image quality.

Limitations of OCR Technology

OCR is essential for translating images and scanned PDFs. Most OCR tools can efficiently recognize horizontal text, but their accuracy in recognizing vertical text is lower.

In vertical documents (such as vertical PDFs or EPUBs), the relationship between characters vertically is much more complex than horizontally, increasing the difficulty of recognition.
