Transparency film is a thin, clear plastic sheet used primarily for creating overhead projector slides and other visual displays. It allows light to pass through, making it ideal for printing images or text that can be projected onto a screen. This film is often used in educational settings, business presentations, and art projects. The film is typically coated on one side to accept ink from printers or markers, ensuring that the printed material is visible when projected. Common types of transparency film include those designed for inkjet or laser printers, catering to different printing technologies and needs.
