In color printing, registration is a method that links overlapping colors to a single image. There are many different styles and registration types, many of them using special alert alignment.

Destination

When printing images or similar packages that have more than one color, you need to print each color separately and ensure each color overlaps with other colors. If this is not done, the finished image will look blurry, blurry or "out of the list" (see picture to right). To help properly align colors, a registration system is required.

Type of lithography registration (rock)

There are many different registration styles for different types of printing. It deals with stone lithography, as used in the art of graphic art.

T-bar

This method, using small registration marks on stones and paper, is very accurate and easy to do. The printer measures the exact paper size and desired margin. Then marks are made on both ends of a piece of paper, and the appropriate marks (usually in the form of "T") are made on stone. Then the printer matches the mark on the paper with the one on the stone. In this way, many different colors can be drawn precisely to each other, each measured from the same sign system.

Pin-hole

This method involves putting the paper on an inkless surface, and making the pin hole through the bottom and top of the paper, being careful to make a mark on the stone surface. Then the hole location is moved to each sheet of paper to be printed. When printing, a person must place a pin on each hole of a piece of paper, and lower it to the inked stone, placing each pin in each hole in the rock. This method can damage the paper by making a hole. And if the hole is too big, they lose its function as a registration device.

Eye-balling

This method only relies on hand-eye coordination. The printer places the paper on top of a rock image, measures and assesses the registration with the eyes. It's not very consistent, depending on the person.
