AGFA PCR II Plus - Pacing Control; Pacing Values and Imaging Speeds

Pacing Control
The pacing control enables you to adjust the film recorder so that its
imaging speed matches the rate of data flowing from the rasterizer.
The PCR II Plus can record 4K images in just over one minute. Some
rasterizers may take longer than this to send complex image files to the
film recorder. When this occurs, the PCR II Plus pauses when it has
imaged all available data and resumes imaging when the rasterizer
sends more data. An interrupted or uneven flow of data from the ras-
terizer can cause artifacts on the recorded images. Regulating the
imaging speed can improve image quality.
Pacing Values and Imaging Speeds
Select SET PACING from the function menu to display the pacing
value.
You can specify pacing values from 3 to 255. Lower numbers mean
faster imaging; higher numbers mean slower imaging.
PACING HS (High Speed) indicates the highest speed for the PCR II
Plus. This is the default setting.
Table 5.1 shows estimated imaging times for different pacing values.
Use this table as a guide for matching the pacing value to the time your
system needs to rasterize an image and send it to the PCR II Plus.
Run an image with the film recorder set to high speed as a test to begin
to judge pacing values. Ultimately, you must rely on your own experi-
ence and testing to select a pacing value.
