This is a GUI-based professional tool that supports ultra-large font automatic pagination, multiple fill styles, custom color configuration, and PDF export for single Chinese characters and symbols.
A cross-platform (Windows / Linux / macOS) ultra-large character automatic pagination printing utility.
- Input: Single Chinese character, letter or symbol
- Output: Multi-page standard PDF file
- Feature: Automatically split oversized characters into standard paper sizes (A4/A3/A0 etc.) for easy printing and splicing into giant characters.
It solves the common limitation of ordinary Word/printing software: inability to scale a single character to an extremely large size or automatically split it across multiple pages. This tool completes the whole process fully automatically.
- Unlimited scaling of a single character
- Automatically split graphics according to standard paper sizes: A4 / A3 / A2 / A1 / A0 / Letter
- Ready for direct printing; pages can be assembled into one giant character
- Solid Color Fill
- Horizontal Gradient
- Vertical Gradient
- Radial Gradient
- Crosshatch Pattern
- Dot Pattern
- Parallel Line Pattern
- Grid Pattern
- Supports TTF / OTF font formats
- Compatible with Chinese, English, numbers and symbols
- Adjustable scaling factor (1 ~ 20×)
- Custom primary and secondary gradient colors
- Adjustable pattern density
- Custom output PDF file path and name
- Grid thumbnail preview for page layout
- Detailed single-page preview
- Click thumbnails to switch between pages instantly
- Vector graphics, lossless at any zoom level
- Directly printable
- Importable into AI / PS / CAD and other design software
