[Chinese Packaging Network News] "Pre-registration" is a type of printing technology that allows for precise alignment without stretching the material. It involves pre-installed plates, automatic registration, and horizontal or vertical positioning, enabling faster overprinting. Many flexible packaging factories are now showing great interest in this advanced method, though some still need to understand its full potential.

1. When using a printing plate with a fixed size, the material length remains almost unchanged, resulting in less waste and faster automatic overprinting.

2. For each rotation of the trapping motor, the material moves at a speed of 1mm per second. The computerized color registration system is fast and accurate, ensuring the material moves up and down without error, reducing both registration time and waste.

3. The gear box with a shaftless design features compact modules, fewer rotations, high precision, and includes a pre-installed plate ruler for even faster pre-setting.

4. By using pre-installed plates, the need to engage the shaftless plate gears and adjust the impression rollers during startup is eliminated. This reduces auxiliary labor, saves materials, and boosts overall efficiency.

5. The automatic pre-registration process minimizes the movement of the ball screw in the upright longitudinal overprint setup. It eliminates the need for initial boot printing, reducing the amount of waste generated at the start and saving valuable time.

6. As the printing market shifts toward multi-category and small-batch production, with more short-lived products changing several times a day, pre-registered printing presses have proven their advantages. They help eliminate the need for small factories to first print test runs, inspect, and then start full production, streamlining the entire process.
