An image data processing method for estimating an ink consumption amount includes: an image data compression step of compressing image data after RIP processing by run-length encoding; and an ink consumption amount estimation step of calculating a predicted ink consumption amount when printing based on image data is performed by an inkjet printing device based on information on the number of occurrences for each gradation value obtained when run-length encoding is applied to image data and information on an ink consumption amount for each gradation value held in an ink consumption amount table prepared in advance.

Image data processing method and printing system

A first RIP processing unit reads cache data from a first cache unit. The first RIP processing unit transmits first RIP-processed variable part data to a printer. Since an identifier read by the first RIP processing unit is not a transmitted identifier, the first RIP processing unit transmits RIP-processed reuse part data to the printer. A second RIP processing unit reads cache data from a second cache unit. The second RIP processing unit transmits second RIP-processed variable part data to the printer. Since an identifier read by the second RIP processing unit is a transmitted identifier, the second RIP processing unit does not transmit the RIP-processed reuse part data to the printer.
