Produce custom printed shipping boxes and labels with ±0.1mm registration accuracy. Our press supports 8-color process printing for exact Pantone matching on large runs, ensuring your brand colors are reproduced flawlessly.
Perfect for custom printing label prototypes and short runs. With HP Indigo digital presses, you get variable data printing capabilities, no plate charges, and no minimums—ideal for rapid market testing and personalized campaigns.
Every custom printed label and box order is backed by our spectrophotometer-verified system, which ensures Delta E < 2.0 color consistency. We provide physical proofs for your approval before any production begins.
Our intelligent scheduling groups compatible orders onto larger sheets. This method efficiently lowers the custom printed shipping boxes cost by up to 30% without compromising on quality or extending your turnaround time.
We expertly print custom printed mailer boxes on a wide range of materials, from corrugated board to synthetic films. Each substrate has a calibrated color profile to ensure vibrant, accurate results every time.


A national retail chain needed to launch new packaging across 400+ store locations within a 6-week window, requiring exact Pantone color matching across multiple substrate types.
We utilized gang-run scheduling on our Heidelberg 6-color press with spectrophotometer-verified color management. Digital prototyping was used for initial approval, then seamless transition to offset for full-scale production.
All 2 million units were delivered on schedule with Delta E < 1.5 color consistency. The client reduced per-unit print costs by 22% compared to their previous supplier through our gang-run optimization.

Our minimum order for offset printing is 500 units. For smaller runs or prototyping, we offer digital production with no minimum order requirement. We can help determine the most cost-effective method based on your quantity and specifications.
We use spectrophotometer-verified color management with Delta E < 2.0 tolerance. Every production run begins with a physical proof approval, and in-line color monitoring checks consistency throughout the run at regular intervals.
Absolutely. Many enterprise clients use offset for high-volume core SKUs and digital for short-run seasonal variants or regional versions. We manage both production streams under a single program with consistent color calibration across methods.
We accept press-ready PDF/X-1a and PDF/X-4 files as standard. We also work with Adobe Illustrator (.ai), InDesign packaged files, and high-resolution TIFF/PSD files. Our prepress team provides free file checks before production.
Yes. We produce custom printed mailer boxes in single-wall or double-wall corrugated, with full-colour exterior printing, interior printing, and premium finishes. Available from 500 units with 7–10 business day turnaround. We can match your brand's Pantone colours and print 4-colour process across all panels.
Offset printing delivers superior colour accuracy (Delta E < 2.0) and lower per-unit cost at volumes above 5,000 units. Digital printing has zero plate setup charges, supports variable data (serial numbers, QR codes, names), and is ideal for short runs of 100–4,999 units or test batches before a full production order.
Cost depends on quantity, size, material, and print complexity. Our gang-run scheduling can reduce per-unit costs by up to 30%. For an accurate quote, provide your specifications for custom printed mailer boxes or shipping boxes, including quantity (minimum 500 for offset).
Lead time varies by production method. Digital runs for custom printing label prototypes can ship in 3-5 business days. Large offset runs for custom printed mailer boxes typically require 10-15 business days, including proof approval. We provide firm timelines upon order review.
We require print-ready PDF files with CMYK color mode, 3mm bleed, and all fonts outlined. For custom printed labels and boxes, include cut lines and provide Pantone references for spot colors. Our maximum sheet size is 720 × 1,020 mm. Our prepress team will review your files before proofing.
Cost depends on quantity, size, material, and print complexity. For standard runs, our gang-run scheduling can reduce costs by up to 30%. We provide transparent quotes based on your specs—contact us with your project details for a precise estimate that leverages our wholesale efficiency.
Turnaround varies by technology. Digital printing for custom printing label prototypes or short runs can ship in 3-5 business days.
