Staircasing

Staircasing is displayed when a detail on the scanned image

 

switches from the scan line to the next line of the grid. This is the

 

same degradation seen on computer-generated images and is

 

most apparent on shallow slopes and soft curves. Staircasing can

 

be minimized by scanning at higher resolutions (more dpi).

 

One factor which can aggravate staircasing is skew. Unlike

 

computer-generated images, scanned horizontal and vertical

 

lines may not be square with the image. A slight skew when

 

feeding the original into the scanner can cause square lines in

 

the original to have a shallow slope on the scanned image, thus

 

introducing staircasing.

Aliasing

 

 

If the spacing of details in an original is close to the dpi of the

 

scanner, aliasing can occur. Aliasing causes a false image to

 

appear over the true image which is illustrated in Figures A and

 

B. Note the heavy diagonal bars over the narrow bars in Figure A

 

and the cross hatch patterns in Figure B. You can reduce this

 

problem by scanning at a much higher resolution or selecting the

 

Screen Removal option of the Image Enhancement filter.
