Hong-Jet® Soft Packaging Film Proofing & Printing Solution | Redefining Efficiency and Cost for Small-Batch Flexible Packaging Production

Summary

In recent years, the rapid growth of e-commerce and the booming fast-moving consumer goods market have made brand customization, channel-specific packaging, rapid new product testing, and category differentiation the new norm. This has triggered explosive demand for small-batch, multi-specification, and short-lead-time flexible packaging.  

Traditional gravure and flexographic printing, however, require high minimum order quantities, expensive plate-making, and long lead times. The high cost of proofing, trial-and-error, and excess inventory makes it difficult for brands to keep up with fast product launches and small-test orders, seriously slowing down packaging iteration and market response.

Against this backdrop, Hong-Jet company has launched its game-changing Hong-Jet® Digital Soft Packaging Film Proofing & Printing Solution. It delivers a true plate-free, short-lead-time, low-cost, fully eco-friendly, and high-fidelity solution for small-batch production in the food, daily chemical, and pharmaceutical industries. Backed by globally leading technology, it has become the benchmark in short-run printing and directly solves the industry’s biggest pain points in small-order production.

I. Background of the Hong-Jet® Soft Packaging Film Printing Solution

The Hong-Jet® Soft Packaging Film Printing solution is purpose-built for short-run printing needs. Centered on JETALL® water-based eco-friendly latex inks and Hong-Jet® dedicated digital printers, it enables rapid validation of design, color, materials, and process compatibility. It dramatically shortens proofing cycles, reduces costs, minimizes mass-production risks, and meets food-contact safety standards as well as green printing regulations.

1. A Groundbreaking Technology Leap

Originally developed for specialty papers and leather, the Hong-Jet® latex printing system surprised our R&D team when they discovered that JETALL® water-based latex inks deliver exceptional adhesion and physical durability on non-absorbent films such as PET and OPP (including scratch resistance, boil resistance, and oil resistance). This breakthrough proved the industrial viability of “water-based ink direct-to-film” printing — a major milestone in flexible packaging since the advent of gravure and flexo.

2. Limitations of Traditional Processes  

The flexible packaging industry has long relied on gravure and flexo — technologies optimized for large runs. They struggle with today’s market demands for small batches, multiple variants, and fast feedback. Core advantages: no need plates making, one-piece minimum order, and instant dry, provide a low-cost, highly flexible short-run solution that eliminates the bottlenecks of new product proofing and small-batch production.

3. Driven by Environmental Regulations  

With increasingly strict global VOC emission controls, flexible packaging companies face heavy environmental compliance pressure. In 2023, JETALL® latex ink was selected into the 16th Catalog of Recommended Advanced Energy-Saving and Emission-Reduction Technologies in China’s Printing and Dyeing Industry, providing strong authoritative support for the Hong-Jet® latex ink printing solution.

II. Core Components of the Hong-Jet® Soft Packaging Film Printing Solution

1. Hong-Jet® 804/1604 Latex Printers  

- 10-color system (CMYK + Lc + Lm + Lk + LLk + White + Spot colors)  

- 1440 dpi high-definition output, optimized for mainstream soft packaging films such as PET composites  

- No-heat platform design: printhead and platform require no heating, preventing film deformation and ensuring accurate dimensions and flat output.

2. JETALL® Water-Based Eco-friendly Latex Ink  

- Eco-friendly & Safe: Water-based formula with zero VOC, no heavy metals, and no irritating odor. Passed SGS and OEKO-TEX® skin-friendly certification; suitable for food-contact packaging.  

- Direct-to-Film Printing: Overcomes the longstanding “poor adhesion on non-absorbent films” issue — no primer coating required.  

- Excellent Post-Processing Compatibility:  

  - Strong adhesion: resists rubbing, scratching, boiling, and oil; survives heat-sealing and sterilization without peeling or fading.  

  - Weather resistance: 5-year outdoor lightfastness; no cracking at -20°C.

III. Proofing & Printing Process

1. Requirement Confirmation & File Preparation

   Confirm material (e.g. PET film), size, color (CMYK/spot), and post-processing needs (lamination, heat-sealing, bag-making).  

   File requirements: CMYK mode, ≥3 mm bleed, ≥300 dpi resolution, spot colors on separate layers with clear notes.

2. Digital Direct Printing (Plate-Free)  

   Using the 804L/1604L latex printer. No plates, no plate costs. Supports small batches from 1 to 500 pieces with fast turnaround.  

   8-color wide gamut delivers accurate spot color and gradient reproduction with minimal color deviation — comparable to gravure.

3. Post-Processing & Finished Sample Production

   Lamination using standard dry lamination processes to verify ink-glue compatibility.  

   Bag-making (3-side seal, stand-up pouch, zipper bag) with simulated production heat-sealing parameters and strength testing.

4. Quality Inspection & Delivery

   Tests include color matching, adhesion (cross-hatch & boil), rub resistance, heat-seal strength, and dimensional accuracy.  

   Delivery: Physical samples + test report within 72 hours. Free revisions and re-prints available within 24 hours of file changes.

IV. Key Advantages

1. Speed: From Two Weeks Down to 3 Days

Traditional gravure clients typically wait 1–2 weeks. With plate-making, press setup, lamination, and curing, even a smooth process takes a week — longer if color matching or scheduling issues arise.  

Hong-Jet®: Plate-free direct printing + fast lamination delivers samples in as little as 24 hours and finished products in 72 hours.

2. Cost: Up to 90% Savings on Proofing

Traditional 4-color plate-making costs around RMB 4,000, plus 15–30% material waste during press setup and color adjustment. With this printing solution, there are no plate fees or setup waste. A standard run of 100 proofing pieces costs just a few hundred RMB. Even after ten file revisions, you only pay for the film used.

3. Materials  

Compatible with mainstream films such as PET composites. Ideal for food pouches, daily chemical labels, pharmaceutical packaging, pet food bags, and gift soft packaging.

4. Food-Grade Safety & Environmental Compliance  

Zero VOC, solvent-free. Fully compliant with GB 4806.10-2016 food contact material standards. Odor-free production improves workshop environment and meets green printing requirements.

5. Superior Print Quality

High opacity, wide color gamut, and precise brand color reproduction. After rigorous evaluation by packaging professionals with 20 years of industry experience, the printed samples earned top marks for detail sharpness, color accuracy, visual layering, and all critical physical performance metrics required for food packaging.

6. Excellent Physical Performance

Finished products demonstrate strong rub resistance, scratch resistance, oil resistance, and boil resistance, easily passing stringent industry tests.
