GRANULARITY PREDICTING DEVICE, METHOD OF PREDICTING GRANULARITY, METHOD OF CREATING PROFILE, AND PRINTER

摘要

PROBLEM TO BE SOLVED: To predict granularity precisely over an entire ink amount space. SOLUTION: An ink amount map, where each position on a two-dimensional plane corresponds to the ink amount, is created by mapping an ink amount space to the two-dimensional plane. Each ink amount corresponding to a plurality of positions equally existing in the ink amount map is acquired as a test ink amount. A plurality of granularity patches are printed based on each test ink amount. A granularity index of each granularity patch is measured. A neural network is created with the test ink amount corresponding to each granularity patch and the granularity index as learning data. The neural network is used to predict the granularity index when print is performed by an optional ink amount. COPYRIGHT: (C)2011,JPO&INPIT
