An image processing system includes control circuitry. The control circuitry acquires print data of CMYK or RGB without a spot color specification. The control circuitry specifies an input profile to convert the print data into a color value in a device-independent space and specifies an output profile for a metallic colorant. The control circuitry separates the print data into five or more plates including the metallic colorant based on the specified input profile and the specified output profile to generate data for a printed material.

An image forming system includes: an image forming unit configured to form an image on a sheet. The image forming unit forms a first image inside a trimming region of a sheet, and forms a second image and an adjustment pattern outside the trimming region of the sheet, the adjustment pattern being for adjusting an image forming condition. Execution of instructions causes one or more processors to adjust the image forming condition at a time of image formation by the image forming unit, and, in a case where a formation region of the second image and at least a part of a formation region of the adjustment pattern overlap, control a display to display information indicating that the formation region of the second image and the formation region of the adjustment pattern overlap.

The laser marking apparatus L includes a printing controller 100 that executes a printing process to form a predetermined printing pattern Pm within a printing area R1, and pre-post printing processes performed before and after the printing process; a storage unit 303 that stores order information Io; a workflow editor 304c that edits a workflow Wf defining a series of processes including the printing process; and an input receiver 304g that accepts selection of pre-post printing processes to be included in the workflow Wf according to user input from the pre-post printing processes. The workflow editor 304c adds the pre-post printing processes, for which selection has been accepted by the input receiver 304g, to the workflow Wf in an order according to the order information Io. The printing controller 100 executes the printing process and the pre-post printing processes in the order defined by the edited workflow Wf.

An image processing apparatus includes a storage unit configured to store a correspondence between input coordinate values in an input color space that depends on an input device and output coordinate values in an output color space that depends on an output device; and a processing unit configured to convert the input coordinate values into the output coordinate values in accordance with the correspondence. The processing unit is configured to perform first adjustment on the correspondence, the first adjustment identifying darkest point output coordinate values that are the output coordinate values of a darkest point in the output color space and associating the darkest point output coordinate values with darkest point input coordinate values that are the input coordinate values of an input darkest point that is a point where brightness is lowest in the input color space, and perform second adjustment on the correspondence, the second adjustment smoothing the output coordinate values corresponding to an adjustment point within an adjustment range around the input darkest point in the input color space based on the darkest point output coordinate values.
