"X Sheets", "Exposure Sheets", and "Gray Sheets" are terms used in the animation industry for the different colored sheets of oversize paper on which lip synch timing information about words and sounds is written, along with other directorial cues, as instructions for the artists who draw each frame. The "X Sheets" generated by the LSM are computer files intended to be printed using your own printer on regular sized 8.5" x 11" sheets of paper. The X Sheet format is a special format that displays lip synch timing information in a way essentially similar to the "Frames" format, except it has been fancied up to look like the Gray Sheets used at either Turner Animation, or at Hyperion. If you require a different output format for your projects (for example, to be printed using your in-house 17"x11" PostScript laserprinter), then please let us know, and we may be able to create a custom format for you for a reasonable fee.
