When scanning transparencies, and to a lesser extent reflection copy, images it is common that unwanted artifacts such as dust and scratches are included in the scanned image. To reduce this effect great efforts in cleanliness need to be applied. Unfortunately this is not enough and it is impossible to avoid dust on transparencies. Scratches of course are impossible to remove once they have occurred. Traditionally this has been resolved with the use of oil mounting which uses a refractive index matched fluid to “fill in” the scratches. Unfortunately this is a skilled job which only high end users are prepared to perform but all users do not want scratches and dust on their transparencies to show up on the scanned image.
