Framing

• Test loops and starting in frame
• Soft matting etc.
• Aperture plates

From the Century Projector Manual: "Rotation of the FRAME knob on the front of the projector causes the intermittent to move up and down. Observe the upper and lower limits of intermittent travel, and position the intermittent at the center of its travel. This will insure adequate movement up or down to correct accidental misframes. Always "center" the intermittent in this manner before threading."

Not all projectors utilize the same framing mechanism as the Century, but making sure your intermittent is both centered and in a neutral position in relation the the Geneva mechanism is a must before starting any show, and MUST be repeated if at any point during a screening you re-adjust the position of the framing mechanism. If you are working with a Simplex XL you'll noticed the intermittent does not move up and down, but rotates. The same principle applies, position the intermittent at the center of its rotation, make sure the intermittent is in a neutral position, and then thread the film.
