The invention provides a safety system for a small arms projectile in which an initiating device is impacted by a firing member in order to detonate a main explosive charge. The system requires the firing member to be retained in a safe position in relation to the initiating device by at least two independent mechanisms. The firing member is initially supported in a forward position, in which it assists in holding the initiator device in a safe condition, and is caused to move rearwardly, through inertia, when the projectile is fired, destroying one of the retaining mechanisms and allowing the initiator device to adopt a primed position in which it can be activated by the firing member which at this time is retained by the other retaining mechanism which is automatically released when the projectile is in flight. The initiator device may, when held in its safe condition, be skewed with respect to the main explosive charge and may incorporate or support a shield disposed, in the safe condition, between the initiator device and the main explosive charge.

An apparatus according to claim 6, wherein said measurement means further measures color data of a third patch for measuring a density, for each ink color, printed by the printing press. 8. An apparatus according to claim 7, further comprising: density calculation means for calculating a density of the third patch from the color data output from said measurement means; density comparison means for comparing a reference density value of each ink color with a density value of the third patch output from said density calculation means; and ink supply amount adjustment means for adjusting an ink supply amount of each ink color in the printing press on the basis of a comparison result output from said density comparison means, wherein said colorimetic value calculation means calculates colorimetic values of the second patch printed by the printing press whose ink supply amount is adjusted. 9. An apparatus according to claim 8, wherein said measurement means, said density calculation means, said density comparison means, and said ink supply amount adjustment means repeat color data measurement, density calculation, density comparison, and ink supply amount adjustment, respectively, until the measured density value of the third patch substantially coincides with the reference density value of each ink color as a result of comparison, and after said density comparison means outputs a comparison result representing that the measured density value substantially coincides with the reference density value, said colorimetic value calculation means calculates the colorimetic values of the second patch printed by the printing press whose ink supply amount is adjusted. 10. An apparatus according to claim 8, wherein said ink supply amount adjustment means adjusts an ink supply amount of each ink color in the printing press in accordance with the comparison result from said density comparison means such that the measured density value of the third patch substantially coincides with the reference density value of each ink color. 11. An apparatus according to claim 6, wherein when the warning is generated, said profile generation means regenerates the printing press profile.
