摘要:
A specific gamut of colors extending a reproduction range of colors in a color space is set to make for any ink color belonging to the specific gamut a conversion from CMYK dot pattern data into numbers of ink drops to be discharged from an inkjet head, using as a lookup table an extended pattern table having a maximal drop number ‘7’. For ink colors belonging to a gamut of colors outside the specific gamut, a default pattern table having a maximal drop number ‘5’ is used as a lookup table for the conversion from CMYK dot pattern data into ink drop numbers.

An adjustment drop number setting section 335 sets a number of adjustment drops with which a change in print density in an image occurs remarkably when an ink drop amount of one ink drop is changed for each kind of a print medium (print sheet) input from an operation panel 340 or sets uniformly regardless of the kind of print medium. When a density difference that requires adjustment is recognized visually between images by two neighboring ink heads on a density measurement chart printed by a chart printing execution section 333c, the ink drop amount of one drop in the set number of adjustment drops is adjusted by adjusting a drive voltage of the ink head of a head unit 110 according to an input from the operation panel 340.

The present invention is a regulating device configured to regulate a temperature T2 of a first medium in accordance with a target temperature. The regulating device comprises a heat exchanger 16, a control valve 14, temperature sensors 2 and 4, temperature sensors 6 and 8, and a heat quantity control unit 30 and a temperature control unit 50 configured to calculate a target exchange heat quantity in the heat exchanger 16, calculate an exchange heat quantity in the heat exchanger 16, add a signal dependent upon a difference between the target exchange heat quantity and the exchange heat quantity to a signal dependent upon a difference between an output of the temperature sensor 4 and the target temperature, and control the control valve 14 so that a difference between the output of the temperature sensor 4 and the target temperature is reduced.

A medium storing a program for display control. When the program is executed by a computer realized in a mobile terminal, the mobile terminal operates as follows. An area-information storing unit stores information on a first display area of an external display device and a second display area of a built-in display. A screen-data production unit acquires content to be displayed, and produces screen data corresponding to the first display area. An entire-image display unit divides the screen data into partial areas each corresponding to the second display area, adds to the entire screen data area-display data indicating the extent of each partial area and a corresponding identifier, and displays the screen data on the external display device. On receipt of an identifier, a partial-image display unit extracts a portion of the screen data for a partial area corresponding to the identifier, and displays the portion on the built-in display.

An ink circulation type inkjet printer includes a maintenance controller configured to: (1) allow a maintenance mechanism to execute maintenance processing for a plurality of inkjet heads before a present printing job under three conditions that: (c1) an elapsed time from a last printing job to a present printing job is less than a first reference time; (c2) the present printing job requests for ejecting ink from unused nozzles of multiple nozzles of the plurality of inkjet heads in the last printing job; (c3) the elapsed time is more than a second reference time; (2) allow the ink circulation type inkjet printer to perform the present printing job without the maintenance processing for the plurality of inkjet heads when the elapsed time is less than the predetermined second reference time.
摘要:
A printing apparatus is capable of printing images by ejecting ink droplets from nozzles. The printing apparatus includes: a drive signal generation unit which generates ejectable drive pulses for ejecting ink droplets based on image data indicating the number of ink droplets for each pixel, and outputs the ejectable drive pulses to the nozzles; and a temperature measuring unit which measures the temperature of the ink. The drive signal generation unit also outputs non-ejectable drive pulses to the nozzle when the ink temperature is lower than a predetermined temperature. The non-ejectable drive pulses are generated and output in order that even when the nozzle is driven by the non-ejectable drive pulses, no ink droplet is ejected. It is therefore possible to provide, without substantially increasing the production cost, the printing apparatus which can elevate the ink temperature irrespective of the print coverage when the ink temperature is low.

An inkjet printer includes an inkjet head configured to perform printing on a printing sheet by use of ink. The inkjet printer includes: a heater configured to heat the ink; a thermometer configured to measure the temperature of the ink; and a controller configured to control the amount of electric power to be supplied to the heater and to control the inkjet head. In a case where the measured value of the ink temperature measured by the thermometer is in a range of a first reference temperature inclusive to a second reference temperature exclusive, the controller calculates a coverage rate of a page to be printed, and accordingly changes the amount of electric power to be supplied to the heater depending on the coverage rate thus calculated.
