Setting Threshold You can sharpen text in a document or reduce show-through in newspapers by adjusting the threshold level via (Threshold) in ScanGear (scanner driver)'s Advanced Mode tab. Note • This function is available when Color Mode is Black and White. • Click Defaults to reset all adjustments in the current window. Adjusting Threshold The brightness of color and grayscale images is expressed in a value between 0 and 255. However, in creating black and white images, all colors are mapped to either black (0) or white (255). "Threshold" is the borderline value that determines a color as black or white. Move (Slider) to the right to increase the threshold value and thus increase the black areas. Move the slider to the left to decrease the value and thus increase the white areas. You can also enter a value (0 to 255). 806
