Viewgraphs, Continued
Diazo
intermediates
You may duplicate artwork to distribute or exchange with other commands.
Duplication eliminates the need to redraw existing art. Duplicate the original
artwork on a diazo intermediate foil such as a sepia, sepia matte, or orange
sepia. Make sure the image is dense. Corrections, additions, or deletions
are easily made on intermediates.
Thermographic
or electronic
production
You can use a copier to produce viewgraphs. The master art need not be
translucent to reproduce on a copier. The only requirement is to change the
paper in the paper tray for acetate. The acetate foil produces a black image
on a clear or colored background. The primary disadvantage of a
thermographic or electronically produced viewgraph is that the image is a
surface deposit of toner that may crack and flake off or be easily scraped.
Computer-
generated
production
Computers are capable of producing viewgraphs. Several software packages
offer image and text integration for export as a viewgraph and/or paper
products. The computer is. also capable of displaying these images on a
monitor or projecting images on a screen much like an overhead projector.
With some presentation software packages, you can command a computer to
change images automatically by entering the seconds of display desired and
the mode of transition.
