Fully Automatic Twin-flow STOP Cylinder Screen Printing Machine (4-post screen lift type-flagship model), linked with twin-flow Feeder

Based on the SL71 4-post screen lift type primeline luxury class flagship model, the SL71/t is further transformed to a unique twin/single-flow compatible model (/t), offers double yield and adaptability to diversified print jobs. Highlights the superior German SPS lineage classic: the “Original SPS STOP Cylinder Principle” in advantages: highest run speed, printing quality, operator convenience and comfort, ever seen in the market)

SPS Feeder (twin-flow type) ahead, 2 types for choice: Rear Pick-up type SPS FVR EP71/t, Front Pick-up type SPS FVF FP71/t, depending on substrate thickness.
Max. speed 4000 cycle/h x1 = 4000 p/h, x2 = 8000 p/h (with EP71/t Twin-flow Rear Pick-up Feeder); Or 2500 cycle/h x1 = 2500 p/h, x2 = 5000 p/h (with FP71/t Twin-flow Front Pick-up Feeder). (max. sheet: single-flow 750x1060mm / 520x500mm x1; twin-flow 520x500mm x2).
• Suitable for paper, plastic, etc. flexible sheet substrates, in [half size small sheet twin-flow, single-flow taking any side of the small sheet twin-flow, full size large sheet single-flow] selectable versatile operation modes, to be printed graphic images, special effects (varnish, relief, particle, gloss…), such as:
- Graphic Printing: posters, packaging boxes/ wraps, book covers, stickers, greeting cards, labels/tags, braille, scratch-offs…
