* Color Alignment: The four dots (cyan, magenta, yellow, and black, also known as CMYK) help ensure the correct alignment of the colors during the printing process. Each color is printed separately, and these marks act as reference points for the printing press.
* Accuracy and Quality: The registration marks allow the printing press to adjust its alignment for each color, guaranteeing that the colors overlap accurately and create the intended images. This helps to prevent blurry or misaligned printing.
* Troubleshooting: If the marks don't align properly, it signals a problem with the printing process, allowing technicians to identify and fix the issue before printing an entire run of newspapers.
Why are they black, blue, pink, and yellow?
These colors are chosen because they represent the four primary colors used in offset printing (CMYK). This ensures that all the colors are represented in the registration mark.
In summary, these four dots are essential for high-quality printing, ensuring accurate color alignment and providing a visual reference for troubleshooting any issues.
