An image forming apparatus not having a spot color printing function and connected a network cannot print out a proper image from image data which is already processed for spot color and stored in an image forming apparatus having a spot color printing function. Preferred implementations of the invention do not require users to manually identify connection types or to manually configure the network device. Additionally, the circuit body may comprise a distal cut zone that provides for freedom of movement of the plurality of distal contacts and a proximal perforated zone that eliminates lead wire entanglements while also allowing for the tearing of perforations between adjacent conductive circuits when a greater reach is required for the proper placement of a distal contact. Different sub-strategies for different frequency ranges include stiffness control, skyhook control, groundhook control, and various damping levels.
