3-16
This function allows a customer to select a threshold curve. Several different curves are prepared, one is
the OCR type and other is the image type. The characteristic of the curve is deferent between IPC-2D and
IPC-3D.
IPC-2D:
The image type curve has steeper inclination in the middle of the curve. For OCR type
curve, the customer can select type (inclination) and density level.
PC-3D:
8 curves are available which adjusts the sensitivity of the image
The parameter of Dynamic Threshold are as follows.
