Step-by-Step: Printing a Multi-Color Cosmetic Bottles & Plastic Cups

Step 1: Precision Screen Stencil

 

The foundation of any quality print is the screen stencil. Our high-tension mesh screens are mounted on CNC-machined frames that ensure uniform tension across the entire printing area. Uneven tension means distorted patterns — we eliminate that variable from the start. Maximum frame size is 600×400mm, with a maximum printing length of 400mm.

Step 2: Custom CNC-Machined Fixture

Every product needs a fixture that holds it perfectly in place. We machine fixtures in-house using our 10 CNC machining centers (±0.01mm accuracy) — meaning we control the quality from raw material to finished product. For cylindrical products, we include one standard universal fixture with every machine. For tapered or conical products (up to 20° taper), we design and machine custom fixtures to ensure perfect registration.

Step 3: UV Ink Preparation — Why Instant Curing Matters

 

Here’s the challenge: when printing multiple colors on a cylindrical surface, each color layer must be completely dry before the next is applied. If you use solvent ink and wait for air-drying, then each color takes 2 hours to surface-dry — making a 4-color job take 8 hours of waiting, not printing. And if you apply the second color over uncured wet ink, then the wet film smears and the pattern is ruined — you waste product, ink, and time.

This is why we use UV inks in this demo: they cure instantly under UV light, so each color layer is dry in milliseconds, which means you can print all colors in a single continuous run without smudging or production delays. The LEUZE contrast sensor then reads each color’s edge and adjusts the next layer’s position — because the ink is already dry, the sensor gets a clean read every time.

The trade-off: UV curing equipment is a separate purchase. If you prefer solvent inks, we can recommend an IR oven add-on that cuts drying time to 1-5 seconds per color — and we’ll show you both options on your live video call.

Step 4: The Blank Product — Surface Preparation Matters

 

Before printing, here’s what most suppliers don’t tell you: PP and PE plastics have low surface energy — if you print directly on them without treatment, then the ink beads up and peels off within days. This is why we recommend flame treatment for PP/PE to increase surface energy and ensure mechanical adhesion. Glass and metal may require a primer. We can advise on the right pre-treatment for your specific material during your free video consultation with our engineers — because the wrong pre-treatment ruins the print, no matter how good the machine is.

Step 5: Finished Product — Sharp, Clean, Perfectly Registered

 

The final result: a clean, opaque print with sharp edges and perfect registration. The LEUZE contrast sensor ensures that every color layer aligns precisely with the previous one — no ghosting, no misregistration. Every machine undergoes a 48-hour burn-in test before shipping, so you can be confident that the quality you see here is the quality you’ll get, batch after batch.

This is the same process our English-speaking engineers will walk you through on a private video call — with your product, your artwork, and your questions.

Q: We print PP cups for bubble tea shops. Why does the ink fall off when customers add ice?
A: This is a material mismatch, not a machine issue. Regular screen ink is formulated for room-temperature adhesion. When the cup surface drops to near-freezing, the ink film loses flexibility and cracks off. We’ll help you select low-temperature PP ink that passes our -38°C freeze test — and we’ll show you the ice test on your own printed cup, live on video. For hot beverages, we offer heat-resistant alternatives too. → Send us your cup — we’ll print a test sample and run the ice test live on video with you.
