Abstract
This invention relates to the printing of transparent media often used for later projection, commonly referred to as Over Head Transparencies, or OHT's. These OHTs are used in several ways: They can be printed in advance and projected in sequence, created in the course of the presentation using marking pens, or a combination of he two, where a pre-printed OHT is edited or modified after printing or in the course of presentation using pens or other marking means. This third use is often compromised by incompatibilities between the marking technology used to create the pre-printed image and the marking pens used to edit the image later. This invention describes a technique for separating the two images, placing each on opposite sides of the transparent film, avoiding this conflict and producing a better solution for the user.
