In the center of the Define Character panel, the following information is
displayed:
G Pixels
The number that appears after G Pixels is the number of green pixels in the
character pattern.
Y Pixels
The number that appears after Y Pixels is the number of yellow pixels in the
character pattern.
G Thin
Shows the current green thin setting. G+ reduces this by 1 and G- increases
this value by 1. The range of G Thin is 1-5.
Y Thin
Shows the current yellow thin setting. Y+ reduces this by 1 and Y- increases
this value by 1. The range of Y Thin is 1-5.
HINTS:
•
The quality of the overall characters on the part may change over time.
If this is the case, the thinning can be changed and the characters
re-taught so that the system will be able to read characters at the
beginning of a run, as well as characters at the end of a run.
•
Using a small number of pixels to represent a character will cause the
recognition to be very sensitive since each pixel is a larger % of the total.
•
Using a large number of pixels to represent a character will cause the
recognition to be less sensitive to print quality changes.
