Từng bước: Cách chúng tôi in cốc cà phê kiểu Starbucks
All images below show real production on the JST‑R300 at our Shenzhen factory.
Step 1: Auto‑Loading Magazine & Conveyor
Automatic cup screen printing machine loading magazine with sensor
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
Robotic arm loading cup into 8-station turntable on automatic screen printer
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.
Corona treatment unit on cup screen printing machine for PP PET cups
Vì 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
Empty fixture detection sensor on automatic cup screen printer
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)
Seam line sensor for paper cup screen printing machine
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
Printing station of automatic cup screen printing machine with dual servo motors
This is the heart of the machine.
MỘT electromagnetic chuck behind the fixture engages and holds the cup firmly.
MỘT 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
Leuze contrast sensor for high-precision overprint on cup screen printer
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
UV LED curing station on cup screen printing machine 1kW 395nm
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
Automatic unloading arm with vacuum suction for printed cups
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
Automatic stacking and counting system for screen printed paper cups
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.
Câu hỏi thường gặp (FAQ)

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 sử dụng một 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 dung môi rửa màn hình 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.
