INK DEPOSITION MONITORING MECHANISM
A system is disclosed. The system at least one physical memory device to store monitoring logic and one or more processors coupled with the at least one physical memory device, to execute the monitoring logic to receive a first and a second ink deposition data representing an output ink amount versus an input digital count for each of a plurality of color planes, determine whether a difference between the first ink deposition data and the second ink deposition data exceeds a predetermined threshold and transmit a signal upon a determination that the difference between the first ink deposition data and the second ink deposition data exceeds the predetermined threshold.
Method and printer system for determining adjusted output settings
A method of printing comprises executing an output settings calibration procedure, the procedure comprising: depositing, by one or more printing elements, ink onto a first substrate according to respective output settings. The procedure further comprises measuring, by a sensor, an actual color value of the ink deposited onto the first substrate at each of a plurality of locations. The procedure further comprises determining a difference between the actual color value and a target color value for each of the plurality of locations and determining adjusted respective output settings for each of the plurality of locations based on the determined difference. The method further comprises depositing, by the one or more printing elements, ink onto a second substrate according to the adjusted respective output settings.
Color calibration algorithm
A method for calibrating a dyeing machine, comprising: for each of multiple colors: performing a maximizing stage to determine an effective maximum ink dispensing rate corresponding to an effective maximum colorimetric value for the dyeing machine; performing a linearizing stage, comprising: determining multiple ink dispensing rates for performing the linearizing stage by dividing the effective maximum ink dispensing rate into multiple intervals, calculating from the effective maximum colorimetric value, a linear correspondence between the multiple ink dispensing rates and multiple calculated colorimetric values, dyeing a set of substrates according to the multiple ink dispensing rates, acquiring color values of the dyed set of substrates, interpolating a non-linear correspondence between the multiple ink dispensing rates and the acquired color values, and mapping the linear correspondence to the non-linear correspondence.
Predicting depleted printing device colorant from color fading
Pixel blocks of a user-generated print job raster page are clustered into raster color clusters, and pixel blocks of a corresponding scanned page are clustered into scanned color clusters. For each raster color cluster, if a color difference between the cluster and a corresponding scanned color cluster is greater than a threshold, color fading of the cluster is determined from simulated depletion of each colorant of a printing device, and a likely depleted colorant is determined based on the corresponding scanned color cluster and the determined color fading. A most likely depleted colorant is determined from the likely depleted colorant predicted for each raster color cluster for which the determined color difference is greater than the threshold.
PROGRAM, INFORMATION PROCESSING APPARATUS, IMAGE FORMING APPARATUS, AND PRINTING SYSTEM
A non-transitory recording medium for an information processing apparatus having a computer program that, when executed by a hardware circuitry of the information processing apparatus, causes the information processing apparatus to request an image forming apparatus to print a document by executing steps of receiving a position of a specific color area which is printed with a specific color; and sending information of the specific color area including the received position of the specific color area and data of the document to the image forming apparatus.
System and method for dosing ink in digital multichannel printers
A data processing method, a system and a user interface are disclosed, for dosing ink in a digital printer with at least 6 ink channels. A forward transformation model is obtained or computed for defining a relationship between coordinates of device-dependent ink values across the ink channels and coordinates of device-independent colorimetric values in a color space. An inverse model of the forward transformation model is computed, wherein the inverse model comprises an adjustable constraint on each ink channel. One or more constraints are applied to each ink channel with predetermined and/or user-defined value(s). A target colorimetric value is input to the inverse model. An ink value is computed for each ink channel with the inverse model, wherein each computed ink value corresponds to ink dosage in its respective ink channel and the computed ink values collectively correspond substantially to the target colorimetric value.
INFORMATION PROCESSING APPARATUS, COLOR CONVERSION PROFILE CREATION METHOD, AND LEARNING APPARATUS
An information processing apparatus configured to store a machine-learned model that learned, by machine learning, a relationship between a type of a printing medium, an amount of a coloring material on the printing medium per unit area, and an image including a linear image and printed on the printing medium; and estimate, based on a selection information and a imaging information, by using the machine-learned model, a limit value indicating a maximum value or a minimum value of an amount of the coloring material to be used for printing on the printing medium by the printing section per unit area; and create, by using the limit value, a color conversion profile including information regarding mapping between a coordinate value in a color space and an amount of the coloring material.
IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM
An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.
DECORATIVE MEMBER MANUFACTURING APPARATUS AND METHOD FOR MANUFACTURING DECORATIVE MEMBER
Provided are a decorative member manufacturing apparatus and method for manufacturing a decorative member, which are capable of reducing an amount of fluid used without impairing a texture of a decorative layer.
In the decorative member manufacturing apparatus and method for manufacturing a decorative member of the present invention, a fluid cured by receiving light is jetted from a jetting part toward a surface of a base material, the fluid which has landed on respective portions is irradiated with light from an irradiation part to form a cured convex portion constituting the decorative layer on the respective portions on the surface of the base material, and the jetting part is controlled based on control data for forming the cured convex portion having a set thickness in the respective portions. In addition, correction processing is performed by a correction part on the control data, the correction processing being a process of reducing a thickness corresponding to a spatial frequency equal to or smaller than a set value, in a correspondence relationship between the thickness and spatial frequency of the cured convex portion which is formed in a case where the jetting part is controlled based on the control data.
