Paso a paso: Cómo imprimimos una taza de café estilo Starbucks

Todas las imágenes a continuación muestran producción real en el JST‑R300 at our Shenzhen factory.

Step 1: Auto‑Loading Magazine & Conveyor

The operator places stacks of blank cups onto the loading magazine. An infrared sensor on the conveyor detects when cups are running low; if empty, the air cylinder lifts the magazine and transfers a new batch onto the belt. This ensures continuous feeding – no manual reloading during production.

---

Step 2: Pick‑and‑Place Robotic Arm

A servo‑driven robotic arm picks each cup from the conveyor and places it into a custom‑machined fixture on the 8‑station turntable. The fixture is CNC‑machined in‑house (accuracy ±0.01 mm) to perfectly match the cup’s taper, guaranteeing zero movement during printing.

🔧 Trust anchor: All fixtures are made on our own 10 CNC machines – we control quality and lead time.

---

Step 3: Corona Treatment (for Plastic Cups – Skipped for Paper)

Para PP, PET, or PVC cups, this station increases surface energy so that UV ink adheres strongly. However, in this paper cup demo we skip corona treatment – paper fibres naturally absorb the ink, so no pre‑treatment is needed. The machine’s PLC allows you to enable/disable this station with one touch.

---

Step 4: Empty‑Fixture Detection – Prevent Ink on Tooling

Before the turntable advances to the printing station, a sensor checks whether a cup is actually seated in the fixture. If no cup is detected, the machine alarms and stops the print head – preventing expensive UV ink from being squeezed directly onto the tooling. This feature reduces waste and tool‑cleaning downtime.

---

Step 5: Seam‑Line Sensor (Optional Add‑on for Paper Cups)

Paper cups have a vertical seam that creates an uneven surface. This optional sensor detects the seam’s position and signals the PLC to skip printing over that area – so your logo never lands on the seam, ensuring a professional finish.

---

Step 6: The Printing Station – Precision in Motion

This is the heart of the machine.

• Un electromagnetic chuck behind the fixture engages and holds the cup firmly.
• A rotary servo motor spins the cup in perfect sync with the screen’s movement.
• Meanwhile, a linear servo motor drives the screen (mesh) left and right via a TBI precision screw.
• The squeegee presses down, transferring UV ink through the mesh onto the cup surface.

All movements are controlled by the PLC and two servo motors – giving you the ±0.1 mm registration that makes multi‑colour jobs possible.

📐 Fixture Customization for Different Cup Sizes: Since cups from 4oz to 32oz vary significantly in diameter, taper, and height, we provide custom‑machined fixtures for each size. This three‑point support design ensures the cup remains stable during printing, thereby avoiding ghosting or misregistration caused by movement. For example, a 32oz large cup requires a dedicated fixture with taller support posts.

---

Step 7: Sensor Swap for Multi‑Colour Overprint

To print a second colour, we switch the seam‑line sensor (for paper cups) with a Leuze contrast sensor. This sensor detects registration marks printed in the first pass and guides the second screen for perfect alignment – achieving multi‑colour results through sequential overprinting, all with the same single print head.

This is how we turn a single‑colour machine into a multi‑colour printer – without investing in a 4‑colour carousel.

---

Step 8: UV‑LED Curing – Instant, Energy‑Efficient

Immediately after printing, the cup passes under a 1 kW UV‑LED lamp (395 nm). The UV light instantly polymerises the ink, so cups can be stacked or packed right away – no drying racks, no waiting. You can adjust curing time directly on the touchscreen PLC to match your ink and cup material.

---

Step 9: Auto‑Unloading with Vacuum Suction

A second robotic arm picks the cured cup from the turntable using vacuum suction and places it onto an outfeed conveyor. Important design note: the fixture must not be too tight – otherwise the suction may not release the cup. Our engineers always verify the fit during fixture design to avoid this issue.

---

Step 10: Automated Stacking & Counting

Cups on the conveyor are aligned and pushed into a stacking magazine. A sensor counts the cups; when the stack reaches a pre‑set count (say 50), an air cylinder separates it, and the stack is pushed to the packaging area. No manual counting or stacking – the machine does it all.

---

Step 11: Finished Product – Starbucks‑Style Coffee Cup

The final result: a beautifully printed tapered paper cup, with crisp edges, accurate registration, and a durable finish that survives hot beverages. Whether you are printing for coffee chains, bubble tea shops, or catering suppliers, the JST‑R300 delivers consistent quality – and you can verify it before you buy.

P: ¿Por qué se despega mi logotipo impreso cuando agrego hielo al vaso?
A: This happens because standard inks become brittle and lose adhesion at low temperatures. For cold‑drink applications, we recommend low‑temperature resistant PP screen printing ink, which maintains adhesion in freeze tests down to -38°C. We can recommend specific ink models based on your cup material and usage scenario. → Contact us for the perfect ink solution for your cold cups.

 

Q: Why do my printed cups have ghosting or blurry images?

A: Ghosting usually comes from two causes: unstable fixturing (the cup moves during printing) or uneven squeegee pressure. Our JST‑R300 utiliza un mechanical rack‑and‑pinion drive combined with a three‑point stable fixture to minimise mechanical vibration. We also provide technical support to help you adjust squeegee pressure (recommended 2.5‑3.0kg) for optimal results. → Contact us for technical support on ghosting issues.

 

Q: What maintenance does the machine require after printing?

A: After each printing session, we recommend cleaning the screen mesh with solvente para lavado de pantalla to remove residual ink and prevent clogging. Regular cleaning extends mesh life and ensures consistent print quality. Our English‑speaking engineers can guide you through the complete maintenance procedure on a video call. → Download our maintenance checklist or schedule a walkthrough.

Cómo limpiar la malla de la pantalla después de la impresión (Guía rápida)

Since screen mesh cleaning is essential for maintaining print quality, here are the basic steps:

1. Remove the screen frame from the machine and place it on a flat, clean surface.
2. Apply solvente para lavado de pantalla evenly over the mesh surface using a soft sponge or brush.
3. Gently scrub both sides of the mesh to dissolve residual UV or solvent ink.
4. Rinse thoroughly with water and blow‑dry with low‑pressure air.
5. Inspect the mesh under light for any remaining ink particles – repeat if necessary.
