Precautions for adjusting the scraper pressure of an oval printing machine

1. Safety first: Before adjusting the scraper pressure, make sure that the printing machine is powered off and in a safe state to prevent personal injury caused by accidental startup.
2. Cleaning work: Keep the scraper, screen and related parts clean to prevent impurities from affecting the accuracy of pressure adjustment and printing quality.
3. Gradual adjustment: The pressure adjustment should be carried out step by step, and tests should be carried out after each fine-tuning to avoid adverse consequences caused by excessive one-time adjustment.
4. Balance on both sides: If it is a double-sided scraper, ensure that the pressure adjustment on both sides is balanced to ensure the uniformity of printing.
5. Reference standard: Refer to the pressure adjustment standard range and recommendations provided by the equipment manufacturer, and do not exceed the specified range.
6. Observe the screen: Pay attention to the deformation of the screen during the pressure adjustment process to avoid excessive pressure damaging the screen.
7. Consider the material: Different printing materials (such as fabric texture, slurry characteristics) may require different scraper pressures, which should be considered comprehensively.
8. Record data: The pressure value of each adjustment and the corresponding printing effect should be recorded for subsequent reference and optimization.
9. Professional guidance: If you are unsure about the adjustment, it is best to consult professional technicians or the manufacturer's after-sales service.
10. Stable environment: During the adjustment process, the temperature and humidity of the working environment must be relatively stable to avoid affecting the test results.
