MIMAKI ENGINEERING CO., LTD.

A printing method for performing printing using a printing device is provided. The method includes: setting a print condition; a checking the print condition; and a print execution stage. The printing device is able to execute a pass modulation operation in which a main scan is executed on the basis of the set number of passes set with an integer value and the number of times of the main scan performed on at least a part of a medium is made larger than the set number of passes. A pass modulation degree is set in the setting of the printing condition. Checking the print condition includes a defective nozzle check stage, checking whether or not nozzle recovery is possible, and searching for a new print condition in a case where the nozzle recovery is impossible.

A jig to be used is appropriately selected, and information necessary for printing is acquired. A printing system includes a print control device that outputs print data; a printing device that executes printing based on the print data; and a jig that is placed on a table of the printing device. Multiple jigs are prepared. A jig ID for identifying the jig is attached to each of the jigs. The print control device includes a jig information acquisition unit that acquires jig information of the jig placed on the table based on the jig ID of the jig placed on the table, and a print data generation unit that generates print data based on the image data and the jig information.

A method for adjusting a printing apparatus includes an analyzing stage of performing, by an image analysis apparatus, analysis on a pattern image generated by reading a test pattern by a scanner, and a setting value updating stage of updating a control setting value stored in a database, in which the printing apparatus is caused to print a test pattern including a pattern for ejecting ink from a plurality of nozzle rows to the same position in a main scanning direction, in the analyzing stage, a dot position misalignment amount occurring in each nozzle row is detected by image processing based on the pattern image, a dot position correction value corresponding to the dot position misalignment amount is calculated by calculation, and in the setting value updating stage, the database is caused to store the dot position correction value as at least a part of the control setting value.

Provided are a maintenance liquid and a maintenance method that can solve an ejection problem of a UV curable inkjet printer. The maintenance liquid includes: a first ingredient in which a water-soluble compound is soluble and a cured matter of a UV curable ink is insoluble. The maintenance method includes: a first cleaning process at which a water-soluble compound that adheres to an inkjet head included in the UV curable inkjet printer is dissolved by a first maintenance liquid including the first ingredient in which the water-soluble compound is soluble and a cured matter of a UV curable ink is insoluble, and a second cleaning process at which the inkjet head is cleaned by a second maintenance liquid including a second ingredient in which the water-soluble compound is insoluble and the cured matter of the UV curable ink is soluble.

A method for generating ejection position data indicating an ejection position where ink is ejected includes performing an edge detection process, an edge correction process, and an ejection position data generation process based on processing target data indicating an image to be printed. In the processing target data, a non-ejection value indicating that ink is not ejected to a corresponding ejection position or an ejection value other than the non-ejection value is set as a pixel value of a pixel. In the edge detection process, a position where a pixel to which the non-ejection value is set and a pixel for which the ejection value is set are adjacent is detected to detect an edge. In the edge correction process, the pixel value of the corresponding pixel is changed to a non-ejection value for at least a part of the ejection position where ink is ejected to draw the edge.

A liquid ejecting apparatus, a liquid ejecting method and an ink are provided, so as to appropriately increase the strength of ink after fixing. The liquid ejecting apparatus is configured to eject an ink by an inkjet method, and includes an inkjet head configured to eject the ink. The inkjet head has a nozzle configured to eject the ink. The ink includes a resin particle having a size capable of passing through the nozzle. The resin particle contains a fibrous substance. The fibrous substance is, for example, fibers of cellulose.

An inkjet printer includes a control unit that counts the number of retries of communication between the control unit and a storage device and communication between the inkjet printer and a host computer and records the same in the storage unit. The control unit can also derive an installation environment level of the installation environment of the inkjet printer based on at least one number of retries recorded in the storage unit, and output the derived installation environment level to a display unit.

An liquid ejecting device includes an inkjet head, a scanning driving unit, a storage, an influence degree storage that stores influence degree information, and a control unit. The influence degree information indicates a magnitude of an influence generated at one ejection position by forming dots of the liquid at each of a plurality of ejection positions. The control unit causes other nozzles to eject a larger amount of liquid than at a normal time with respect to at least a part of the ejection position where the liquid is ejected by the other nozzles in the vicinity of an abnormal nozzle at the time of main scan, and selects an ejection position to which the other nozzle ejects a larger amount of the liquid than the normal time based on the influence degree information.
