Colors of printed materials are easily matched. Provided is a print management system used in a printing system including a plurality of printing presses and performing printing using plates respectively created for each printing press. The print management system includes a tone-curve storage unit for linking and storing identifying information of the printing presses and tone curves for the printing presses; a communication device for obtaining binary image data from a host system; a binary-image-data correction unit for creating binary image data for each of the printing presses by correcting the binary image data using the tone curves stored in the tone-curve storage unit; and CTPs for creating respective plates for each of the printing presses on the basis of the corrected binary image data.

A communication apparatus, such as a facsimile machine, for transmitting and receiving data to and from a device, includes a transmitter for receiving a first signal from the device and transmitting, in response to the first signal, a second signal for a predetermined time period. The transmitter receives a third signal from the device in response to the second signal, and transmits a fourth signal when the third signal is not received within the predetermined time period and transmits a fifth signal when the third signal is received within the predetermined time period. The transmitter receives a sixth signal from the device in response to the fourth signal. A detector, connected to the transmitter, detects which of the third signal and the sixth signal is received from the device. A controller, connected to the transmitter and the detector, controls a protocol of transmission and receipt of the data.
