Frameline creep and shift
If frameline creep exists, make a note of the overall direction of creep (usually determined by winding the film through a ganger). Spacing may need to be inserted to accommodate the changes in frameline position.
If frameline shift exists, make a note of the direction in which the frameline moves (i.e. towards head or tail) at each shift.
The greatest amount of adjustment the printer has is in the direction of printing; so if the frameline shifts towards the head, then choose to print from the tail and vice versa.
