Why don’t you try the handbook layering game with fluorescent pen ink?

Scientific discovery of fluorescent pen ink

In 1852, Stokes observed that quinine sulfate solution emitted longer-wavelength light when irradiated with short-wavelength light, such as ultraviolet. The human eye is more sensitive to certain wavelengths, and the light emitted by fluorescent dyes often falls within this range, making fluorescent colors visually striking. This is why fluorescent ink appears very eye-catching.

How to Use Fluorescent Pen Ink in Handbooks

In handbooks, you can use fluorescent pen ink to annotate text, adding color to plain content. You can also embellish pages with simple patterns like dots, circles, or triangles for visual interest. Additionally, creating color-changing effects with fluorescent ink can enhance the artistic appeal of the handbook.
