Over the past two decades, a few developers and researchers have been trying to solve the issue of image spread correction in variable area negative soundtracks. They were initially aiming to save time and money on the optical transfer process by avoiding the printing of new sound positives.
With the present paper, I aim to emphasise the higher quality achievable with the features of the optical soundtrack scanners available nowadays, rather than just the economical advantages.
After a brief technical explanation of what image spread is, how it is generated by optical recorders and fixed by either positive prints or scanners, this proposal will analyze some specific, yet broadly recurring issues in variable area optical soundtracks, and explain how these can now be solved by scanner technology.
The approach proposed by this paper will link each setting of optical scanners to precise examples of audio and optical damage or human mistakes
coming from a particular period, film stock, or film sound technology.
Finally we will try to envisage some possible developments of scanner technology, especially the increased collaboration between archives and laboratories, achieved by splitting raw scan and post processing and deploying the two processes to their most suitable environment.

Employed by “l’Immagine Ritrovata” of Bologna, Italy, as Head of the Sound Department, specialized in sound restoration. The high-end restoration projects come from the collaboration with the World Cinema Foundation, and are regularly screened at Cannes, Venice and Berlin Festivals. The laboratory features international partnership with national film archives all over the world.
Duties for the post-production projects include all aspects of Sound Tech. Dialogue editing, re-recording, sound design, optical soundtrack recording, sound and music consultant for features, short movies and documentaries and overseeing the installation of new systems and expansion of existing system.
