Automatic (CCD) Sheet Screen Printing Machine

What are the main components of an automatic (CCD) sheet screen printer?

The main components of an automatic (CCD) sheet screen printer include:

CCD camera system: responsible for high-precision image capture and position correction to ensure accuracy and consistency of printing.

Printing platform: carries the material to be printed and provides stable support. Usually has automatic adjustment function to adapt to materials of different sizes and thicknesses.

Screen frame: a bracket on which the printing screen is installed. The screen is coated with photosensitive glue for transferring patterns.

Scraper system: used to print ink onto the surface of the material through the screen. The pressure and angle of the scraper can be adjusted to control the thickness and uniformity of the ink.

Ink supply system: includes ink barrels, pipes and pumps for delivering ink to the screen frame. Ensure a stable supply and consistency of ink.

Drive system: includes electric motors and transmission devices for controlling the movement and operation of the machine. The drive system ensures that each component operates according to the predetermined program.

Automatic alignment system: uses sensors and cameras to automatically align materials and patterns to ensure that the printing position is accurate.

Heating and drying system: used to heat and dry the ink after printing to accelerate the curing process and improve production efficiency.

Control panel: used to operate and monitor all functions of the printing press, including setting printing parameters, starting and stopping the machine, etc.

Safety devices: including protective covers, emergency stop buttons, etc., to ensure the safety of operators and prevent accidents.

How to ensure color and pattern accuracy when using an automatic (CCD) sheet screen printer?

There are many aspects to ensuring color and pattern accuracy in an automatic (CCD) sheet screen printer, and here are some key measures:

Calibrate the CCD system: Regularly calibrate the CCD camera system to ensure the accuracy of its image capture and position correction. Ensure that the camera is well aligned and the image is clear.

Consistency of materials and screens: Ensure that the materials and screens used are consistent in size and quality. Any inconsistency in materials or screens may affect the printing results.

Ink control: Use high-quality, suitable inks and ensure that they are mixed evenly. The viscosity, drying time and color concentration of the ink should meet the requirements.

Color management system: Implement a color management system, including color calibration and color matching tools, to ensure that the printed colors are consistent with the design requirements. Use color standard samples for comparison and adjust the press settings to match the target color.

Accurate registration and alignment: Use an automatic registration system to ensure accurate registration of materials and patterns. Perform regular checks and adjustments to ensure accuracy every time you print.

Printing parameter settings: Adjust printing parameters such as scraper pressure, screen tension and printing speed to optimize printing quality. Each material and ink may require different settings.

Pre-printing test: Perform sample tests and small batch production to verify the accuracy of color and pattern. Make necessary adjustments based on the test results.

Maintenance and cleaning: Regularly maintain and clean all parts of the printing machine, especially the screen frame and scraper system, to prevent contamination and impurities from affecting printing quality.
