DT-CNC-120S Semi-Automatic Servo Screen Printing Machine
The DT-CNC-120S is an operator-loaded screen printing machine for bottles and shaped containers. Four servo-controlled movements manage print-head position, screen travel and product rotation, while optional camera or optical registration can be used for applications that require repeatable multi-color positioning.
Servo-controlled printing in a standalone semi-automatic machine.
The DT-CNC-120S uses the same type of servo-driven motion and programmable control approach found in the larger DT-CNC automatic systems, but keeps part loading, unloading and color changeover with the operator. This provides a practical machine configuration for lower-volume production, frequent changeovers and applications that do not require a fully automatic rotary line.
Load, unload and manage the printing process
The DT-CNC-120S remains a semi-automatic machine. The operator loads the product into the fixture, removes it after printing and manages screen, ink and color changes as required by the job.
Servo control handles the critical printing movements
Four servo-driven movements control print-head travel, vertical print-head movement, screen stroke and fixture rotation. Job settings are established through the PLC and touchscreen rather than relying only on mechanical or pneumatic adjustment.
Re-locate the product for the next registered color
Camera artwork positioning or an optical sensor can be used to locate a reference on the product. The fixture servo then rotates the container to the programmed position before the next print cycle.
Four servo-controlled movements manage the print cycle.
The DT-CNC-120S uses servo motors for print-head horizontal travel, print-head vertical travel, screen stroke and fixture rotation. These movements are coordinated through the machine controls so the print cycle can be set around the actual container geometry and artwork location.
Print head left and right
Servo-driven horizontal head travel positions the printing assembly through the programmed cycle.
Print head up and down
Servo-driven vertical stroke controls approach, print contact and return movement.
Screen stroke
Independent servo drive controls the screen movement rather than relying solely on a pneumatic cylinder.
Fixture rotation
Servo-driven part rotation coordinates the container surface with the screen during printing.
Camera or optical positioning for registered multi-color printing.
For multi-color applications, the DT-CNC-120S can use camera-based artwork positioning or an optical sensor to locate a reference on the part. The fixture servo then rotates the product to the programmed angular position before the next color is printed.
Camera artwork positioning
The camera system views the product and uses a visible reference from the existing decoration or part to establish orientation. The fixture servo can then rotate the product to the programmed printing position before the next print cycle.
- Useful when the job requires visual artwork-based alignment
- Allows orientation to be corrected through servo-controlled fixture rotation
- Camera registration is selected when the artwork or product provides a reliable visual reference
Optical registration
For jobs with a feature that can be detected by an optical sensor, the sensor provides the reference point and the servo fixture rotates the product into the programmed print position.
- Compact sensing method for a detectable artwork or product reference
- Servo rotation establishes the angular position before printing
- Best suited to a defined optical target with sufficient contrast
How a multi-color job runs on the DT-CNC-120S.
For additional colors, the operator returns the part to the fixture. The selected registration system locates the reference, the fixture rotates to the programmed position, and the next color is printed. Drying and curing are configured for the ink and application.
Place the product into the dedicated fixture.
Establish product orientation with the fixture, camera or optical reference.
Run the programmed servo motion for the current color.
Handle curing/drying and screen or ink changeover as required.
Reload the product and locate the prior print or reference.
Rotate to position and repeat the controlled print cycle.
Designed for round and shaped containers.
The DT-CNC-120S is designed for round, oval, square, triangular, hexagonal and octagonal containers. Print area and tooling are engineered around the actual part and artwork.
PLC and touchscreen control of machine motion and job settings.
The Inovance PLC and Weinview touchscreen coordinate the servo-driven movements from one operator interface. This is the control layer that lets the machine be set around the product geometry, print stroke and registration method rather than relying only on pneumatic cylinders and fixed mechanical stops.
Camera or optical sensing is selected from the actual part and artwork.
Camera vision and optical sensing serve different registration needs. Deco Tech selects the appropriate method based on the container, artwork, print locations, substrate, cure method and production target.
Confirm geometry and print surface
Review the container shape, dimensions, material, wall strength, existing decoration and the exact areas to be printed.
Identify what the machine can locate
Determine whether the application provides a reliable visual artwork reference, optical target or mechanical orientation feature.
Build the fixture and motion profile
Support the product and program screen travel, print-head movement and fixture rotation around the actual print geometry.
Prove registration and print quality
Confirm registration behavior, adhesion, appearance, cycle requirements and downstream handling before production release.

When the DT-CNC-120S is the right level of automation.
The decision is primarily about production volume, operator involvement and how much of the process needs to happen automatically. The 120S keeps handling with the operator while automating the critical print motion and registration functions.
Use the 120S when flexibility matters
Well suited to operator-loaded production, multiple SKUs, frequent job changes and single- or multi-color container printing where servo-controlled motion and registration are required without a full rotary automation line.
