The digital printing machine (referred to as digital machine) is a new generation of plate-free digital printing equipment that subverts the traditional offset and flexo plate making processes, eliminating the need for film output, plate making, plate exposure and development. Relying on high-precision inkjet/electrostatic imaging digital imaging technology, computer files can be directly transmitted to the machine for printing.

The equipment supports printing on various materials including sheet-fed and roll materials, and is compatible with ordinary coated paper, cardboard, special paper, adhesive labels, synthetic paper, laminated substrates, etc. It supports four-color printing, white ink priming, spot color printing, variable data printing, and one-to-one variable QR code/barcode printing. Widely used in graphic quick printing, label packaging, color box proofing, small-batch orders, tender document and album production, and bill tag production; it focuses on small-batch, multi-batch, quick order change and on-demand printing, solving the industry pain points of traditional printing such as high minimum order quantity, time-consuming typesetting and plate making, and high proofing cost. It is a standard digital printing equipment for printing factories, graphic stores and packaging factories.

How to choose:

1. Selection According to Own Production Orders (Primary Standard)
• Graphic Stores (Albums, Tender Documents, Leaflets): Choose small and medium-sized sheet-fed color digital machines with low speed and high cost performance to meet daily scattered orders.
• Label/Packaging Factories (Adhesive Stickers, Color Box Proofing): Choose roll industrial digital machines with white ink configuration to adapt to post-press lamination and die-cutting.
• Factories with Large-Batch Short Orders: Choose high-speed industrial-grade digital machines that support 24-hour continuous mass production.
• Traceability and Anti-Counterfeiting Orders: Must choose special models that support variable data.

2. Selection According to Printing Material and Grammage:

For ordinary printing on thin paper, standard commercial models are sufficient; for thick cardboard, special hard paper and substrates that are easy to curl, choose custom sheet-feeding models for thick paper to prevent paper jamming and smudging.

3. Core Hardware Configuration Screening:

Prioritize nozzle life, imaging system, sheet-feeding transmission system and drying and curing system; for high-frequency production, prefer imported nozzles and high-power drying modules to avoid ink splashing and color smudging during long-term printing.

4. Ink System Selection:

For indoor ordinary printing, use water-based pigment ink; for outdoor packaging products, use UV curing ink; for processes requiring white ink priming, choose special models with built-in white ink channels.

5. Selection of New vs. Used Machines:

For long-term stable mass production, prefer brand-new complete machines; for low budget and transitional production, choose high-quality used digital machines with new appearance and no major repairs; avoid equipment with major repairs, burned nozzles and modified circuits.

6. After-Sales and Supporting Services:

Prioritize merchants that provide on-site installation and commissioning, on-site training, nozzle warranty and remote after-sales service; nozzles of digital machines are core vulnerable parts, so brands with local after-sales outlets are preferred.

How to use:

1. Pre-Startup Preparation
• Check the equipment power supply, network cable, ink level and waste ink tank capacity.
• Clean paper scraps and impurities in the paper infeed and outfeed channels.
• Start self-inspection, the equipment automatically calibrates the nozzles and drying system, and preheats for 5-10 minutes.

2. Standard On-Machine Operation Process
• File Import: Connect the computer to the equipment, upload PDF/print original images, and set parameters such as size, color sequence, double-sided/single-sided and variable data.
• Material Feeding: Place paper/printing substrates flatly and calibrate the paper infeed and outfeed stop gauges.
• Test Proofing: Print 1-2 sample sheets at low speed, check color, size and clarity, and fine-tune color parameters.
• Mass Production: After confirming the sample is correct, start fully automatic mass printing.
• Discharging and Collecting: The equipment automatically dries and discharges the products, collect the finished products in stacks, and directly enter post-press lamination and die-cutting processes.

3. Daily Maintenance (Key to Extend Machine Life)
• Daily: Clean the nozzle surface, paper infeed and outfeed rollers, and waste ink tank; check for residual impurities from paper jams.
• Weekly: Clean ink path pipes, calibrate colors, check drying fans and sheet-feeding sensors.
• Monthly: Dedust the whole machine, fasten transmission parts, upgrade the control system, and check circuits.
• Long-Term Shutdown: Seal the nozzles, empty excess ink paths, and store in a moisture-proof and dust-proof environment.

4. Usage Taboos
• Prohibit the use of inferior compatible ink.
• Prohibit overweight and over-specification plates from being put on the machine.
• Prohibit forced power off and cover opening during production.
• Prohibit long-term operation in high-temperature and humid environments.

Q1: Broken ink, ink splashing, striped color loss in printed patterns

Slight nozzle clogging, air intake in the ink path, insufficient ink level. Solution: Perform automatic nozzle cleaning on the equipment, replenish original ink, empty air bubbles in the ink path, and let the ink stack reset after standing.

Q2: Smudged printed products, undried ink, paper sticking on the back

Too low drying/curing power, too fast printing speed, mismatched ink and material. Solution: Increase the drying temperature, reduce the printing speed, and replace with special ink suitable for the substrate.

Q3: Frequent paper jams, skewed paper feeding, slipping during paper infeed

Dirty and dusty paper-feeding rollers, damp and curled paper, improperly adjusted stop gauge spacing. Solution: Clean the transmission rubber rollers, flatten and dry the paper, and fine-tune the spacing of the paper infeed and outfeed baffles.

Q4: Large color deviation, serious color difference, inconsistent with the sample

Uncalibrated color parameters, ambient light interference, ink precipitation. Solution: Perform ICC color calibration on the equipment, stir the ink, turn off ambient strong light interference, and fine-tune the four-color concentration.

Q5: Garbled variable data printing, unreadable QR codes

Abnormal data system connection, insufficient nozzle printing precision, wrong file format. Solution: Restart the data background, calibrate the printing resolution, and correct the format of the printing source file.

Q6: The machine starts normally but cannot receive printing files from the computer

Network cable/local area network failure, invalid driver program, stuck industrial control system. Solution: Check the circuit and network, reinstall the equipment driver, and restart the industrial control host.

Q7: Nozzles are easily damaged, high maintenance cost

Use of inferior off-brand ink, long-term failure to clean the ink path, excessive dust in the workshop. Solution: Use original consumables throughout, maintain nozzles regularly, and carry out dust-proof operation in the workshop.

Q8: How to choose between new and used machines for better cost performance?

Choose brand-new digital machines for long-term stable large-batch production; choose high-quality used machines without major repairs for graphic stores, short-term transition and small-batch proofing, with low investment and quick return.
