What is your idea of the image about the printing sheet registry operation?

Perhaps something similar to the following image:

The use of print registries in this way caused a lot of errors and was extremely challenging to use in orders that required very high registry accuracy.

The first and at the same time the simplest weakness of these types of registry signs was their thickness. We all know that the line is naturally thick, although this thickness can be very small. However, if the print sheet was not registered for any reason, the thickness of the lines can be adjusted by the operator.

Suppose that in a four-color CMYK image, yellow is associated with a registry error, but due to the thickness of the registry lines as well as the higher black coverage power, this error can be negligible.


Another major flaw was the human error in monitoring the registry, which sometimes had catastrophic results. Despite all its evolution and complexity, human eyes can make a variety of errors about control concepts, as well as the sign of the registry.

These two reasons would have ultimately led to slower production and production speeds, if it had viewed by the operator, and time spent directly or indirectly modifying the registry directly or indirectly affected the print quality.

For these simple reasons, the world’s printing industry has forgotten the old registry lines and used the ACR system instead.

ACR has a very simple yet extremely clever notion. The ACR, which is derived from the automatic camera register, uses lines instead of points and also uses the equipment’s infallible eye instead of human fallible control.

printingIn this way, the registry sign points are read by a camera and automatically corrected, if necessary by the machine itself. Due to the fact that the dot is virtually not thick, in case of displacement or problems in the registry angles, the defect is quickly observed and corrected by the printing equipment. This will minimize the possibility of error and minimize the time spent for troubleshooting.

All the new Teram Industrial Group printing devices are equipped with ACR technology, and our first experience with ACR was exciting, in addition to being extremely precise, as it brought us one step closer to producing precise, fault-free products.
