AUTOMATICALLY RECONFIGURING A WEB PRINTER
In one example, an inkjet web printer includes a print engine and a controller programmed to determine that a second print job following a first print job may be printed without stopping the web and, without stopping the web, cause the print engine to print the second print job.
Photo-curable ink jet ink set and ink jet recording method using the same
A photo-curable ink jet ink set includes an undercoating photo-curable ink jet ink containing a (meth)acrylic acid ester having a vinyl ether group expressed by general formula (I), and an overcoating photo-curable ink jet ink. The undercoating photo-curable ink jet ink has a higher surface tension than the overcoating photo-curable ink jet ink.
METHOD FOR PRODUCING RELIEFS BY MEANS OF DIGITAL PRINTING AND DIGITAL PRINTING MACHINE
A method for producing reliefs through digital printing and a digital printing machine is disclosed by method providing a substrate having a first digital print on one of the faces; applying a coating on the face of the substrate with the first digital print; partially drying the coating until a gelled state is obtained; depositing drops of ink to produce a second digital print; applying pressure to the gelled coating using an embossing roller to obtain a three-dimensional structure, the embossing roller configured to receive the second digital print and produce the three-dimensional structure; and completely drying the coating on which the three-dimensional structure has been obtained.
RECORDING HEAD CLEANING DEVICE, RECORDING HEAD CLEANING METHOD, AND RECORDING DEVICE
Provided is a recording head cleaning device, a recording head cleaning method, and a recording device, with which a cleaning liquid from a nozzle is prevented from being mixed and a nozzle surface is cleaned. The problem is solved with a recording head cleaning device including a cleaning liquid holding unit that has a cleaning liquid holding surface, a cleaning liquid applying portion that applies a cleaning liquid to the cleaning liquid holding surface, a cleaning unit that cleans a nozzle surface of a recording head, in which a nozzle jetting an ink is disposed, with the cleaning liquid held by the cleaning liquid holding surface by making the cleaning liquid holding surface and the nozzle surface face each other, the nozzle surface with the cleaning liquid held by the cleaning liquid holding surface, and a back pressure control unit that sets a back pressure of the nozzle in a case of cleaning the nozzle surface to −800 pascals to −200 pascals.
Posture adjusting apparatus and inkjet image forming apparatus
A posture adjusting apparatus includes: an ink ejector that has a detachable inkjet head that ejects ink; and a posture adjuster for adjusting a posture of the ink ejector. The ink ejector includes a head fixing member to/from which the inkjet head is attached and detached, and is movable between a first position where an image is formed on a recording medium by the inkjet head and a second position where the inkjet head is attached and detached, and the posture adjuster allows adjustment of an angle of the head fixing member in the second position.
Printing apparatus and printing method
A printing apparatus includes a printing unit discharging a plurality of different pigmented inks onto a transfer member and forming an ink image, a processing unit performing processing such that each of the pigmented inks applied on the transfer member forms a layer, and a transfer unit transferring the ink image from the transfer member onto the printing medium conveyed by the conveyance unit. The pigmented inks include cyan, magenta, yellow, and black inks as pigmented inks of four basic colors, and at least one pigmented ink different from the pigmented inks of basic colors. A first ink at least one of the pigmented inks of the basic colors is applied onto the transfer member after a second ink is applied. The second ink is the pigmented ink different from the pigmented inks of the basic colors and has a color material density lower than that of the first ink.
INK DISCHARGE COMPLEMENTING METHOD AND PRINTING APPARATUS
The conversion of the dot percentages using the first conversion table Td1 and the second conversion table Td2 is performed for the gradation data Dh by the defective nozzle corrector 95. Here, the first conversion table Td1 converts the dot percentages of the pixels Px corresponding to the normal nozzles Nn having no discharge defect by the first rate Rd1 lower than 100%, and the second conversion table Td2 converts the dot percentages of the pixels Px corresponding to the surrounding nozzles Na located around the defective nozzle Nd by the second rate Rd2 higher than the first rate Rd1. Then, the shading correction is performed for the defect complemented gradation data Dc obtained by converting the dot percentages in this way by the shading corrector 96.
Printing apparatus and printing method
A printing apparatus is provided that includes a line type printing head ejecting an UV ink onto a base material, an ultraviolet irradiator disposed downstream of the printing head, a mist retrieving section having a suction port and disposed between the printing head and the ultraviolet irradiator, and a control unit, wherein when printing is performed, the control unit adjusts, in accordance with a transport speed of the base material, at least one of a gap A, a gap B, and a suction air volume of the mist retrieving section such that a direction of an airflow passing through a gap between the base material and the ultraviolet irradiator is opposite the transport direction of the base material. The gap A is a gap between the printing head and the mist retrieving section, and the gap B is a gap between the base material and the suction port.
PRINTING APPARATUS
Since a head part is arranged in an inclined posture, the ink ejected from a nozzle surface of the head part may drip to a first lower surface peripheral edge portion along the nozzle surface, and then drops from a first long side of a lower surface of the head part toward a first side wall of a cover member being arranged below the head part. The first side wall having an upper end portion is located away from the first long side. Thus, the dropped ink is collected by the cover member without being attached to the upper end portion of the first side wall. Therefore, the ink can be prevented from being solidified at the first lower surface peripheral edge portion and the reattachment of the ink to the nozzle surface can be effectively prevented.
RECORDING DEVICE AND RECORDING METHOD
A recording device includes a recording unit configured to discharge a plurality of colors of ink, and a control unit configured to control the recording unit to perform recording of an image on a recording medium, wherein the control unit is configured to perform color expansion processing to copy, to a target pixel, a recording amount of first ink included in another pixel, the target pixel and the other pixel configuring image data representing the image, the target pixel being adjacent to the other pixel, the other pixel including the recording amount of the first ink of the plurality of colors of ink, the target pixel including a recording amount of second ink of the plurality of colors of ink, and cause the recording unit to perform recording based on the image data after the color expansion processing. The target pixel does not include the recording amount of the first ink, and the second ink has a different color than the first ink.
