• Monitor:
At least 1024 x 768 pixels resolution
Memory requirements
In the following chart the possible sizes of plots were calculated.
The sizes of plots depend on the size of the main memory. In
the first chart you can see the results for documents with an av-
erage complexity and in the second the results for documents
with high complexity.
Further assumption are:
The sizes of plots depend on the size of the main memory. In

Further assumption are:
• All calculations are based on a transportation speed of 90
mm/s.
mm/s.
• Scan and plot degree is 1 bit/pixel
• Usage of average document complexity.
• Usage of 128 MB for operating system Windows 2000 and
related drivers.
