The Rosette pattern serves as a visual quality control benchmark in the Industrial Printing Process. The presence and correct formation of this flower-like pattern confirms that the Screen Angle of all four CMYK colors is properly set, and there is no interference between the dots. Conversely, any anomaly or conversion of this pattern into wavy shapes is a direct sign of a Moire error, requiring a print stop and immediate recalibration.

Technical teams use print loupes to inspect the Rosette in midtone areas. If the center of the Rosette is incorrectly formed or the dots are positioned at inappropriate angles, the CTP device calibration and the Screening settings in the RIP must be checked. This diagnostic process ensures that print waste resulting from poor Halftone quality is minimized and that the final product colors possess the necessary stability and accuracy.
