“We were printing sheet labels on three office devices and hoping for the best,” says Liza Mercado, Operations Director at PakSend Asia, an e-commerce fulfillment specialist based in Manila. “We needed a path that supported growth and our sustainability targets without overwhelming the team.”
PakSend’s label work touches thousands of outbound parcels daily and a small but exacting cosmetics private label. Early on, they leaned on desktop tools, including a basic 30-up layout in Word, and outsourced higher-end jobs when color had to match packaging consistently. The result? A mix of workable and frustrating.
From our sustainability lens, the brief was clear: streamline production with Digital Printing, cut waste in a practical range, and align material choices to FSC and food-contact expectations where relevant. Here’s where it gets interesting—their story is less about buying a machine and more about building a reliable process that the team can actually run.
Company Overview and History
PakSend Asia started as a logistics aggregator, then moved into in-house labeling when e-commerce volumes spiked across Southeast Asia. Most jobs are Labelstock on A4 or SRA3—classic sheet labels—with variable data for SKUs and ship-to information. They also handle a modest cosmetics line where brand color matters. As growth picked up, the team realized ad hoc solutions wouldn’t scale or meet evolving sustainability goals.
Historically, they used a simple 30 labels per sheet template word layout for short-run shipping batches. It worked, but templates didn’t solve color drift or curl on Glassine liners. Leadership set a target to align with FSC for paper-based Labelstock and reduce reprints. The decision to evaluate Digital Printing came after comparing ΔE results and waste rates from outsourcing versus in-house jobs on office devices.
Quality and Consistency Issues
Color was the first friction point. The cosmetics team flagged brand red drifting beyond ΔE 4–5 on some runs, especially during humid afternoons. On Glassine liners, adhesive behavior changed with ambient conditions—a common issue in Asia—leading to edge lift and occasional misregistration. For their high-end cosmetics SKU—marketed internally as top high-end labels—they needed tighter control, closer to ΔE 2–3 and stable registration across batches.
Waste rates were also uneven. On busy days, scrap hovered around 1,800–2,200 ppm defects, mostly from color mismatch and curl post-print. Changeovers were slow, and operators relied on manual checks. It wasn’t catastrophic, but it chipped away at confidence. “We didn’t need perfection,” Liza notes. “We needed repeatability we could trust.” And trust, in label production, is built on process, not promises.
Q: Team members kept asking about how to edit labels in gmail. A: Gmail labels organize emails—helpful for workflow—but they don’t modify packaging artwork. For layout and data merge, the team standardized on Word/CSV for utility work and the RIP’s variable data module for production-grade runs. That small clarification cut a surprising amount of miscommunication.
Solution Design and Configuration
The team selected Digital Printing for Label production—primarily aqueous (Water-based Ink) for most jobs and UV Ink on a second line where scuff resistance mattered. Substrates were FSC-certified Labelstock with a mix of Glassine and film liners. An inline Varnishing unit and Die-Cutting improved flow. G7-based calibration brought ΔE down into a 1.5–3.0 range on controlled days. For micro-barcodes on multi-SKU batches, they adopted an 80 labels per sheet template approach, while fulfillment kept the familiar 30 labels per sheet template word for quick utility runs like free shipping labels.
Here’s the catch: Water-based Ink needs careful drying. They added airflow management and tuned temperature settings to balance energy and throughput. LED-UV was reserved for scuff-prone SKUs to avoid over-coating. Changeovers moved from roughly 25–35 minutes to 12–18 minutes, aided by preset recipes and substrate profiles. Not magic—discipline. Operators followed a checklist that included humidity checks and adhesive verification before the first sheet.
On sustainability, the move trimmed CO₂/pack by about 8–12% compared to their old mix of outsourced and office-device work, based on their internal model. LED-UV slots showed slightly higher kWh/pack versus aqueous, but fewer reprints offset that. The goal wasn’t chasing a single number; it was creating a system that balanced color, waste, energy, and operator workload. Training included both the why and the how.
Quantitative Results and Metrics
Six months in, acceptance rate (a proxy for FPY%) rose into the 90–94% band on typical runs. Waste fell into a more comfortable 800–1,100 ppm defect range. ΔE stayed under 2.5 for brand-critical colors when humidity held around 45–55%. Throughput rose 15–20% on days with steady SKU mixes, while mixed, last-minute batches sat closer to 8–12%. Payback Period penciled out at about 10–14 months, depending on how you account for rework avoided.
Lessons learned: Humidity is not a suggestion; control it. Glassine works, but needs discipline on storage and handling. Some durability-heavy SKUs still fit better on Thermal Transfer with industrial ribbons, and that’s okay. The broader takeaway? When you build a practical system around sheet labels, the team stops firefighting and starts producing with confidence—and sustainability stops being a separate project and becomes part of daily decisions.
