Color bar is a series of small color patches printed along the top edge and the full length of the print area, serving as a guide for control to ensure proper and uniform color balance during printing.
Place at Bottom : The color control bar will be positioned at the bottom of the paper instead of the default top-edge position. Only the default color control bar is available in this mode.
Solid Swatches : The color bar consists of 100% solid swatches of the colors without incorporating various shades of a single color.
Small Control Bar : Instead of the full-width color control bar, this option adds a small control bar comprising only a few patches.
Vertical Control Bar : The color control bar will be positioned on the left side of the paper instead of the normal top-edge position. Only a small color control bar is available in this mode.

Gray Balance : Adds a gray balance control strip to the output. This strip will print on all separations of the layout as a series of swatches with different percentages. Its purpose is to ensure that the gray produced by the combination of all inks matches the maximum possible gray tones, minimizing any color casts.
Star Target : Inserts a star target (also known as a Siemens star or spoke target) for detecting smudging, slurring, misregistration, and other print quality issues. This target is critical for evaluating print sharpness, ensuring precise alignment, and diagnosing press or mechanical inconsistencies. More star target options can be found in the additional marks section.
Control Bar Color : Output color control bar using selected color swatch other than default.
To use custom-colored marks, color bars, or slug lines, attach the required custom color swatch from the color swatch library. For grayscale printing, attach and select the default grayscale black swatch to enable grayscale marks.
Setup : Allow to select the custom color swatch from the list.
Control Wedge : Allows inclusion of a control wedge PDF in the output. A control wedge is a digital tool used in the printing industry to ensure the accuracy and consistency of color reproduction across different printing devices and jobs. It is also used to check the quality of imaging on a printing plate. Typically, it consists of a series of color or gray patches, gradients, and patterns covering a range of tones or colors.
Control Wedge Settings :
Position : Specifies which side of the signature the control wedge PDF will be placed on.
Centered : Positions the control wedge PDF centered on the selected sides of the signature.
On Plate Edge : Enables positioning the control wedge PDF from its default position, aligning it adjacent to the plate edge rather than the total signature crop box.
Margin : This field allows you to position the control wedge PDF from its default position, either adjacent to the total signature crop box or on the plate edge, depending on the selected default position.
Offset : This field allows you to adjust the control wedge PDF sideways from its default position. The direction of adjustment depends on the position of the control wedge: horizontally for top or bottom positions, and vertically for left or right positions.
