Transparencies are sheets of clear paper used for displaying images on overhead projectors. They are usually made of celluloid and coated with a special backing, which allows it to absorb dyes from pens or printers. They are usually designed for computer printers, but most can also be written on with transparency markers.
Types of Transparencies
Kinds of Transparencies include the following:
Inkjet transparencies are designed to hold liquid ink from inkjet printers.
They take longer to print and dry, but usually provide the best color and clarity.
Laser transparencies absorb laser beams and toners from laser printers.
They print faster than inkjet transparencies, but are more expensive and offer limited color options.
Copier transparencies are designed to withstand heat from plain-paper copy machines.
They have fast print rates and are commonly used to reproduce images printed on regular paper.
Choosing Transparencies (Buying tips)
Heat resistance: Choose a transparency that can withstand heat from printing without melting or blotting the ink. Look for thick but clear sheets with firmly applied coating. Drying time: Choose a transparency that absorbs ink quickly to prevent smudging. Choose a laser or copier transparency for printing high-resolution images, because liquid ink can smudge or blot when applied in multiple layers.
