WebOffset error defines how well the actual transfer function of a DAC matches the ideal at a single point. For a unipolar output, this is at code zero. This error is often called zero-code error. For a bipolar output, this is at the point where the DAC output should pass through zero. Gain error is a measure of the slope of the transfer function.
