 Despite these systems for marking reel changes, some projectionists working with platters or other large-reel transport systems were careless or intentionally negligent when breaking down prints. In the worst cases, the projectionist would ignore the original reel breaks and simply wind the film onto each reel until it was full and then make a new cut in the middle of the reel. This often went uncorrected at future venues. Even reel-to-reel theaters would often recue the poorly cut reels instead of restoring the original reel breaks.
-Another source of intentional print damage is the application of the [[foil cues|foil cue tape]] required by [[automation systems]]. Aluminized mylar tape was applied as strips or small circles, and the reflective surface triggered a sensor as it passed through the projector. Strip cues are particularly problematic because they take up more surface area and can be more difficult to remove, and when they are removed they can leave significant adhesive residue. Cues within the picture area are also visible on screen. Dot cues are less problematic because they take up less surface area (in 1.85 prints they could even be hidden by placing them in the cropped portion of the frame) and are easier to remove without damaging the print. In addition to foil cues, alternative systems were designed using barcodes stickers, but these were only employed on a large scale but the United Artists theater chain. These stickers were applied to the center of the frame and were very difficult to remove without damaging the print. Thoughtful projectionists would apply clear splicing tape beneath the cues so that they could be peeled off with less risk of scratching the picture area.
