How to use:

1. Pre-Startup Inspection: Check whether the equipment power supply, optical path and transmission system are normal; clean the plate table, adsorption and positioning components; verify the specifications of flexible plates, confirm that the equipment parameters are reset to zero, and ensure the precision of the plate making benchmark.

2. File Preprocessing and Import: Perform imposition, dot optimization and defect removal on the printing files, and adjust dot compensation parameters according to the flexo printing process; after importing into the system, set parameters such as resolution, plate making speed and positioning parameters as required.

On-Machine Plate Making Operation: Start the integrated plate making process for fully automatic models; for semi-automatic models, manually arrange and place the plates, start exposure for plate making after precise positioning; regularly inspect the imaging effect during mass production to ensure uniform dots.

4. Post-Processing and Quality Inspection: After plate making, carry out developing, drying and curing, and spot-check the plate dots, clarity and registration accuracy; regularly calibrate equipment parameters during mass production to avoid the accumulation of dot deviations.

5. Shutdown and Daily Maintenance: Turn off the power supply after production, clean the optical path lens, plate table and transmission parts; regularly calibrate the laser energy and positioning accuracy, inspect the transmission components, and keep daily maintenance records of the equipment.

Q1: What is the difference between flexo CTP and offset CTP?

Flexo CTP is specially optimized for flexible plates and water-based ink flexo printing processes, with a built-in flexo dot compensation algorithm that can effectively suppress dot gain and plate pasting. It is suitable for soft plates and various water-based ink printing, and its plate making logic and imaging parameters are completely different from those of offset hard plate CTP.

Q2: Is the equipment suitable for water-based flexo ink production?

Fully suitable. The plate has clear mesh holes and a clean surface, with uniform ink loading and releasing. It can perfectly match the production of all series of water-based ink flexo printing products such as paper bags, non-woven fabrics, labels and cartons, effectively reducing the printing defect rate.

Q3: What to do if small dots are lost, blurry or seriously enlarged after plate making?

This is mostly caused by improper dot compensation parameters, laser energy deviation or plate problems. Recalibrate the flexo dot compensation parameters, adjust the laser energy, and use qualified new plates to solve the problems of blurry dots and dot loss.

Q4: What causes inaccurate multi-color overprinting and large batch color difference?

It is caused by positioning deviation and inconsistent parameters. Regularly calibrate the positioning system, fix the plate making parameters for each batch, and unify the dot gain settings to ensure precise multi-color overprinting and consistent batch colors.

Q5: What if the imaging depth is uneven and the plate surface is mottled during plate making?

It is caused by dust accumulation in the optical path, unstable transmission or energy fluctuation. Clean the optical path lens, start the equipment's automatic calibration function, and inspect the transmission structure to restore the imaging uniformity.

Q6: What if the equipment has unsmooth plate feeding or plate positioning deviation?

It is caused by dust accumulation in the adsorption mechanism, plate deformation or loose positioning parts. Regularly clean the equipment, arrange the plates neatly and flatly, and fasten the positioning components to ensure smooth plate feeding and precise positioning.

Q7: What if water-based ink piles up and loads unevenly on the plate after plate making?

It is caused by unclear plate mesh holes and residual impurities on the plate surface. Optimize the plate making parameters, clean the equipment regularly, and ensure a clean and clear plate surface to significantly improve the problems of uneven ink loading and ink piling.

Q8: Can it be adapted to various flexo products such as corrugated, flexible packaging and non-woven fabrics?

Yes. The equipment has adjustable parameters and wide adaptability. By switching the plate making mode, it can be adapted to various flexo products such as corrugated cartons, flexible packaging, paper bags, non-woven fabrics and adhesive labels.

Q9: How to select the most suitable model for different flexo products?

Choose standard models for ordinary carton printing; select high-definition models for paper bag, non-woven fabric and label printing; opt for high-precision high-configured models for high-end fine packaging and multi-color gradient products.

Q10: How to perform daily maintenance to reduce the failure rate?

Clean the optical path and plate table daily, calibrate the laser energy and positioning accuracy weekly, regularly inspect the transmission and plate feeding mechanisms, and keep the workshop dry and dust-free to stabilize the equipment precision and extend its service life.
