In the printing world, a register refers to how text or images align on a page. When professionals discuss “register,” they usually refer to alignment in one of two senses: either how images align (sometimes called “image registration”) or how colors do (“color registration”).
Image registration entails ensuring that visuals on a page line up with each other precisely. Printing small marks at each corner of the page often achieves this; printers use them as reference points.
Color registration means assuring that different colors mix seamlessly on an image destined for print. Small marks are typically printed onto each color layer so printers can line everything up perfectly.
Proper alignment of images and colors is crucial in printing to achieve a clean and professional final print.
In printing, the register refers to aligning the printed elements horizontally and vertically. This involves aligning the left and right sides and the top and bottom. Images must also be published in the register, meaning matching up the top, bottom, and left and right sides.
When print elements are not correctly aligned or in the register, they can appear blurry, smeared, or misaligned. This significantly impacts the overall look of the printed piece and makes it challenging to read. Particularly for images, even a slight misalignment can result in blurriness or distortion. Therefore, ensuring that all print elements are correctly registered is essential for achieving a polished and professional appearance.
