Automated One-Pass Digital Printer for Molded Pulp Products with
Integrated Loading & Curing
Our Automated One-Pass Digital Printer revolutionizes post-molding
decoration by applying high-quality prints directly onto molded
pulp products—including plates, bowls, trays, clamshells, and
industrial cushioning—in a single, continuous operation.
Eliminating the need for manual handling or pre-drying, it takes
products directly from the forming press, precisely prints logos,
graphics, or variable data, and delivers them cured and ready for
packaging. The system achieves exceptional registration accuracy of
±0.3 mm (customizable to ±0.1 mm with vision system) and supports
customizable print widths up to 600 mm, with resolution up to 600 ×
600 dpi.

Customization Options
- Printing Size & Configuration: Tailoring the print width (up to 600 mm or more), number of print
heads, and color stations (monochrome to full CMYK with optional
white and varnish)
- Ink System: Selecting the optimal ink chemistry (water-based for food
contact, UV for durability and abrasion resistance) based on your
substrate (wet/dry) and end-use requirements (food safety, outdoor
exposure)
- Material Handling: Customizing the feeder and unloader mechanisms to match your
product's specific shape, size, and fragility—whether plates,
bowls, cups, or complex trays
- Software Integration: Developing customized communication protocols to sync with your
line's master PLC or MES system for full factory automation

ensure sharp, durable prints even on porous, textured molded pulp
surfaces
- Quick Changeover & Flexibility: Digital design files allow for instant job switching—from logo to
logo, one batch to another—without physical plates or screens,
making short runs and customized batches economically viable
- Robust & Reliable Construction: Built for 24/7 industrial environments with easy-access
components for straightforward maintenance
- Sustainable Operation: Utilizes eco-friendly inks (water-based pigment) and
energy-efficient UV-LED curing, fully aligning with the green ethos
of molded pulp packaging

Frequently Asked Questions
Q1: Can this digital printer handle freshly molded (wet/damp) pulp
products, or do they need to be completely dry?
A: Yes, it is specifically engineered to print on both semi-dry
(wet-pressed) and fully cured substrates. Ink formulation and
curing settings are customizable for optimal adhesion and image
quality on either substrate condition. For wet products, UV-LED
curing is especially effective as it fixes the ink instantly
without smearing.
Q2: How quickly can we switch from printing one product design to
another?
A: Designs are changed digitally in seconds. Simply upload a new
graphic file to the printer's onboard computer. No physical plates,
screens, or manual tooling changes are required—saving hours of
changeover time and making short-run customized batches
economically viable.
Q3: What is the typical ink consumption and operational cost?
A: Ink consumption is highly efficient due to non-contact,
drop-on-demand printing—only depositing ink where needed. Exact
consumption depends on coverage area and print density. The system
is designed for economical operation even in customized, short-run
jobs, with significantly lower material waste than conventional
labeling or pad printing.
Q4: How is color consistency maintained across different production
batches or when making repeated orders for the same brand?
A: The system uses closed-loop color calibration and automatic
print head maintenance cycles (capping, purging, wiping) to ensure
consistent, repeatable print quality over time and across multiple
production runs—critical for brand compliance.
Q5: Can this printer apply white underbase or varnish as a topcoat
for special effects?
A: Yes. The system supports customizable color configurations—from
monochrome (black ink) to full CMYK. An optional white ink channel
and/or varnish module can be added for printing on dark-colored
substrates, covering background patterns, or applying protective
overcoat.
