FP20 Philips Kinoton 35mm filmprojector, Film Damage

Film damage, what is it? And how can you prevent this?
Also with the trailer AmadeuS and cinema advertising from the 70s and 90s.
Alcohol and cigarette advertising were viewed differently then, fortunately that is different now.

Film beschadiging, welke zijn er? En hoe kan je dit voorkomen?
Ook met de trailer AmadeuS en bioscoop reclame uit de jaren '70 en '90. Tegen alcohol en sigaretten reclame werd er toen anders tegenaan gekeken, gelukkig is dat nu anders.
