A line art work or drawing is one where the lines are black against a white background or visa versa. While it might appear that there is a range of grey tones in the image these might be made up of a series of black lines. The closer the lines the darker the tone – the wider apart the lines the white the area appears.

The image might appear to be a line drawing but contain continuous tone information like an old drawing where the tone and texture of the paper is to be carried over into the copy. These drawings would be seen as a continuous tone image rather than a line drawing. Avoid images which are printed in a book with a half tone screen.
