摘要： Densities of detecting patches also called control scales printed on prints in a first print job are used to control the feed rate of dampening water in a second print job following the first print job. Specifically, densities of detecting patches on the prints obtained from the first print job are measured, and a feed rate of dampening water is calculated from the densities of the detecting patches. A base feed rate of dampening water is calculated based on the feed rate calculated and a humidity and temperature occurring when the first print job is performed. A proper feed rate of dampening water is calculated based on the base feed rate and a humidity and temperature occurring when the second print job is performed.

摘要： First, densities are measured of a set of detecting patches having an equal number of lines and different area ratios between a printing area and a non-printing area, a set of detecting patches having an equal area ratio between a printing area and a non-printing area and different numbers of lines, and solid patches. Next, area ratios S relating to quantities of dampening water are calculated by using density of the set of detecting patches having the equal number of lines and different area ratios between the printing area and non-printing area, and density of the solid patches. Then, coefficients N relating to emulsification rates of ink are calculated by using density of the set of detecting patches having the equal area ratio between the printing area and non-printing area and different numbers of lines, and the density of the solid patches. Finally, a feed rate of dampening water is adjusted by using the area ratios S and coefficients N.

摘要： A color density measuring step is executed for measuring color densities of unprinted areas on prints. Then, a determining step is executed for determining from the color densities of the unprinted areas on the prints whether ink tinting has occurred. When the determining step determines that ink tinting has occurred, a dampening water adjusting step is executed for adjusting a dampening water feeding rate after feeding dampening water in an increased rate once. A variation in the ink feeding rate is prohibited for a predetermined waiting time after feeding dampening water in the increased rate once in the dampening water adjusting step.

摘要： An ink supply controller capable of generating a proper ink curve from a result of printing even when there is a small difference in image area percentage between ink key regions is provided. The ink supply controller includes an old job data storing element for storing old job data; a new job data acquiring element for acquiring new job data; an ink curve generating element for generating an ink curve based on the old job data and the new job data; an ink curve display element for displaying the generated ink curve; and an updating element for updating the old job data by using the generating ink curve. The ink curve generating element acquires data parameters for generation of the ink curve from both the old job data and the new job data to set an approximate curve obtained from a distribution of these data parameters as a new ink curve.

摘要： A controller in the example of this invention operates to perform flushing by ejecting three types in size of ink droplets, i.e., smaller, middle and larger ink droplets, from each of nozzles. Then the controller operates an ink-droplet detector to perform an ejection test to detect ejection conditions. Thereafter, the controller operates an ink supply section to perform cleaning in accordance with results of the test. A combination in size of unejected ink droplets indicates a defective condition of the nozzle. Consequently, varying the degree of cleaning the nozzles in accordance with the size of the unejected ink droplets may achieve cleaning in a shorter time of period. As a result, time for cleaning the nozzle can be suppressed. This leads to a decreased proportion of maintenance to a starting time in an apparatus and increased availability of the apparatus.
