1. Production Speed
Theoretical Speed: Industrial-grade rotary screen printing machines can reach speeds of 60-100 m/min (domestic models) or 3,500 yd/h (imported models). The magnetic scraper system is over 30% more efficient than a metal scraper.
Actual Speed: This depends on the fabric type. For example, lightweight fabrics can run at full speed, while heavier fabrics require a reduced speed of 50-70 m/min to prevent uneven colorant penetration.
2. Screen Changing and Downtime
Fast Screen Changing: Single-color rotary screen changing should take less than 5 minutes. Multi-color machines should be equipped with an automatic registration system to minimize downtime.
Belt Maintenance: The frequency of rubber belt washing and adhesive replacement affects continuous production time. High-efficiency machines should support online cleaning (such as the self-cleaning belt system offered by Jilong Machinery). 3. Equipment Utilization
Color Capacity: 24-color models can produce complex patterns in one go, reducing plate changes. For small-batch production, a 4-8-color model is recommended.
In-line Processing: Integration with drying and die-cutting equipment can improve overall efficiency. For example, a rotary screen printer and die-cutter can achieve speeds of up to 60 meters per minute.
4. Process Compatibility
Pattern Restrictions: The maximum pattern size is determined by the circumference of the rotary screen (640-1018 mm). Patterns exceeding 40 inches require separate plates, which may reduce efficiency.
Colorant Control: High-mesh screens (≥120 mesh) are suitable for fine patterns but require reduced speeds. Low-mesh screens (80-100 mesh) are suitable for large-scale production.
