2. Highlights of the Product

The UV colour inkjet printer is an industrial-grade digital inkjet equipment that adopts UV curing technology to achieve high-definition full-color printing and instant drying on various material surfaces. In recent years, the global UV digital inkjet printer market has experienced rapid growth, with a market size of 3.18 billion US dollars by 2027 and is expected to reach 7.48 billion US dollars by 2032, with a compound annual growth rate of 12.98%. As an important base of global printing equipment manufacturing, Shenzhen, China has gathered advanced technology research and production capabilities to provide high-performance colour UV inkjet printers for global users. Next, we will systematically introduce the core functions of the device from ten dimensions below.

1.Fast printing.

The colour UV inkjet printer uses industrial grade piezoelectric nozzles and a one-pass printing architecture, which allows the materials to print continuously through a fixed nozzle array, replacing the reciprocating motion of traditional scanning print heads, and greatly improving the production efficiency. The device provides printing speeds of 30 to 50 meters per minute and can still provide stable output even at high resolution of 600 × 1200 dpi. The speed of side printing is also up to 20 meters per minute in the assembly line operation mode. This speed advantage can enable bulk products such as tea packaging bags and mobile phone protective films to achieve a daily output of tens of thousands of pieces, greatly improving the operating efficiency of large-scale production lines.

2. High-precision printing

The device has a multi-level adjustable horizontal precision of 200 dpi – 1200 dpi, with a maximum resolution of 1440 × 1440 dpi. Single nozzle contains 1280 to 25600 nozzles, using Variable Droplet Technology (VSDT) with a minimum ink drop of 3.2 microlitres to achieve photo-level delicate output effects. High-precision printing supports character output of at least 1 mm, which can clearly display small graphic elements such as QR codes, one-dimensional codes, anti-counterfeiting codes, etc., and has a one-time recognition success rate of various variable code systems. The high-precision capabilities guarantee sharp edges of patterns and clear and recognisable text for mobile phone protective films, fine patterns on licence plates, and anti-counterfeiting labels.

3. Colour saturation. Vibrant choices.

The device is equipped with a CMYK four-colour basic ink system and can expand special colour channels such as white, light cyan, light colour and gloss oil to meet the needs of wide colour gamut printing. We use industrial piezoelectric nozzles of Epson, Ricoh and other brands with a negative pressure ink supply system to ensure stable ink flow, controllable ink usage and cost savings. The curing process employs UV-LED cold light source technology that generates very little heat on the surface of the material and prevents the deformation problems of heat-sensitive substrates. Quality performance of colour UV inkjet printers can be comparable to offset printing, easily meeting the high requirements of high saturation and colour richness for products such as mobile phone protective films and plastic lunch boxes.

4.Customisation personalised.

The device supports small batch or even single piece customised production, without the need for plate making or immediate printing and drying. Content for printing can be imported directly from design files, so that changes to orders can be made quickly and drastically reducing the time and cost of plate-making needed for traditional screen printing or offset printing. The colour UV inkjet printers can complete the conversion from brand logo customisation and personalised pattern design to packaging appearance adjustment for different batches in minutes, meeting the global customer’s market trend demand for “one item, one print”. This feature has great flexibility and commercial value for small batch diversified orders such as tea packaging bags, tags, gift packaging, etc.

5. Proven and mature technology.

The equipment employs a modular design and industrial-grade piezoelectric nozzle technology. The nozzle lifetime is up to 100 billion actuations. The integrated board supports USB 3.0 and fibre optic data transmission, which guarantees stable and efficient data communication. The negative pressure ink path control and positive pressure nozzle cleaning functions effectively reduce the probability of blockage, ensuring the reliability of long-term operation of the equipment. The industrial design of the complete machine is well proved in production, also for a 24 hours continuous production environment. Over years of accumulated global market application, the equipment has undergone on-site inspections of its technological maturity by customers in multiple industries such as printing and packaging, label hanging and electronic products.

6. The structure is strong and durable.

The equipment uses a high-rigidity integrated frame and modular chassis design, and the X-axis uses imported double-row guide rails combined with linear motor transmission. The magnetic grid reads data to be assured of printing accuracy and overall stability of the machine. Some models offer detachable chassis to cut down on transportation costs and make installation and deployment easier. Automatic lifting function and anti-collision device are equipped in the nozzle area, effectively protecting the core printing components. After long-term high-speed operation verification, the equipment can satisfy the industrial-grade operation standards in terms of strength and durability, reducing the frequency of downtime maintenance.

7.Good material compatibility.

Colour UV inkjet printers can directly print on dozens of common materials, such as coated paper, white cardboard, art paper, film, synthetic paper, and various substrates, such as PVC, PP, PE, PET, BOPP, aluminium foil composite film, etc. Good adhesion is possible for non-permeable materials like metal, glass, ceramics, acrylic, and permeable materials like paper, cardboard boxes, wood, etc. The equipment can process three-dimensional workpieces with a thickness of more than 10 cm and supports two feeding modes of roll-to-roll and single sheet to meet the printing needs of tea packaging, foam egg boxes, plastic lunch boxes and other materials.

8.Printing of variable data.

Colour UV inkjet printers can print 1D codes, 2D codes, anti-counterfeiting codes, images, custom numbers, text, serial numbers, databases, Hanxin codes, dot matrix codes, lines, boxes and other rich content. Massive amounts of data from files such as EXCEL, GSV, CSV, TXT, etc. can be directly read through independently developed variable data editing software, with a maximum single data import volume of over 10 million entries. Realised “one item, one code” printing speed of millions of times per second. Whether it is the unique traceability QR code for tea packaging bags, the serial number on the tag, the production batch code for mobile phone protective films or the anti-counterfeiting label for plastic lunch boxes, they can be efficiently completed on a production line. The device provides an open third-party interface, which is easy to integrate with existing customer systems such as ERP, anti-counterfeiting management systems, PLC, etc., meeting the needs of enterprises for customised data management.

9. Detection of read/write and intelligent complement.

The colour UV inkjet printer is equipped with a high-precision visual inspection system, which reads the printed code in real time and performs quality verification during the printing process. When non-conforming labels are identified, the system automatically activates the removal function to divert defective products from the production line. For the situations that there is no coding on the label due to the nozzle blockage or other reasons, the equipment can automatically supplement the coding and reprint, to ensure the production line yield. This function is particularly important in mass production of label products such as hang tags and adhesive labels, and can greatly reduce the cost of manual quality inspection. With duplicate code detection function, the software can automatically trigger an alarm when duplicate codes are encountered, ensuring data uniqueness.

10.Plasma surface engineering technology.

The equipment may include an online plasma processing system for activating the material surface prior to printing. The plasma system generates high-energy ion gas flow that greatly enhances UV ink adhesion on difficult-to-adhere materials by eliminating micro-pollutants, increasing surface energy and improving ink wettability. This technology is especially effective on packaging films with low surface energy materials such as PP, PE, PET, BOPP, etc. The plasma-treated substrate improves the printing clarity, wear resistance and scratch resistance of colour UV inkjet printers significantly to avoid the pattern shedding in the following transportation and use. It is especially suitable for applications with strict surface requirements such as flexible packaging bags, plastic lunch boxes and synthetic paper labels.

3.Use Cases

Colour UV inkjet printers have been widely used in packaging, labelling, consumer electronics and daily necessities industries due to their excellent material compatibility, high-speed and stable printing and flexible data management systems. Below is a detailed introduction to each typical application scene.

Tea bag packages. The printing quality required for tea packaging is extremely high, with patterns and colours that are full and durable for storage. Tea bags are usually made from aluminium foil composite films, PE/PET films or coated paper, which have low surface energy and put stringent requirements on ink adhesion. The colour UV inkjet printer with integrated plasma surface treatment function can realise high adhesion printing through surface activation pretreatment. Cures instantly under UVLED, with bright colours and scratch and water resistance. The device supports dynamic variable data printing of one item and one code, and can print the product traceability source code or the product traceability QR code on each packaging bag, which can meet the needs of brand anti-counterfeiting and market management.

Clothing tags, hang tags. Hang tags, washing labels, tags, etc. are often made of copperplate paper, synthetic paper or special materials and need to carry rich and changeable information. Colour UV inkjet printers are clear to print clothing specification codes, washing symbols, brand logos, one-dimensional and two-dimensional codes and other content. The visual inspection system automatically identifies incomplete or deviated content and removes it, completely solving the problem of defective products flowing out due to printing defects. Support database import and serial number printing, easily meet the production requirements of thousands of different encoded hang tags. The clothing and packaging industry has adopted this solution in place of the old carbon ribbon heat transfer printing method, cutting down on consumable waste and labour expenses.

Lunch box, plastic. Lunch boxes for children and adults are generally made of materials like PP and food grade plastic. Colour UV inkjet printers can print directly with safe, low-VOC, environmentally friendly UV ink that is cured instantly by UV light to prevent the ink from migrating to food-contacting areas. The printer can print cartoon patterns, brand logos, nutritional information chart, production dates and QR codes. After plasma surface treatment, the ink adheres firmly to the smooth plastic surface with good friction resistance, which can meet the requirements of multiple cleanings and uses. This device also supports small-batch personalised orders and zero plate making without waiting for manufacturers of gift food boxes and takeaway food packaging boxes, and can receive orders and produce at any time.

Protective film for mobile phone. Mobile phone films are mostly smooth materials such as PET, TPU, glass, etc., and traditional printing has the problem of insufficient adhesion. Colour UV inkjet printers can activate the material surface before printing through the integration of plasma surface treatment technology, so that the adhesion of ink is greatly improved. The product may include brand, batch number or instructions to realise a one-time printing effect on the edge pattern of the phone film or the packaging box. By using high-precision nozzles, the minimum character printing can be as low as 1 millimetre, and the minimum size of QR codes can be controlled within 3 × 3 millimetres. Nowadays colour UV inkjet printing solutions are adopted by a large number of accessory manufacturers to achieve efficient batch and customised compatible production modes.

Manufacture of license plates. Motor vehicle licence plates must be highly resistant to outdoor weather conditions and able to hold clear patterns, sharp edges and bright colours in high sunshine conditions. The ink of the UV inkjet printer contains high concentration pigment particles, which have excellent sun resistance and corrosion resistance. The content of the vehicle licence plate is printed in real-time variable data of one object, one code including number text, QR code and anti-counterfeiting graphics in the same process. The device has a read-write detection function. Once the number plate number printing is complete, the system automatically verifies it. In case of a missing or incorrect number, it can be reprinted immediately, or defective products can be recorded. This type of colour UV inkjet printer has been widely used in multiple licence plate processing and export enterprises in Zhejiang, Guangdong and other places.

Egg carton. The surface of an egg box made of foam or pulp is uneven and often has a profiled surface or a polyhedron structure. Traditional screen printing technology is hard to cover the multiple sides at the same time, and the cost of mould customisation is high. The colour UV inkjet printer can choose the three-sided one-time printing moulding solution, which can simultaneously print texts, images and barcodes on the top and side surfaces. The operation speed of the assembly line can be up to 20 metres per minute. The device enables instant changeover printing, independent of product batch, channel or differences in sales region, with no requirement to change moulds and digital file switching can be completed in a few minutes. Egg box factories can also print information like origin, batch code and QR code on each egg tray to promote the construction of a cold chain traceability system for poultry and egg products.

Soft packaging bags, zipper bags. Different substrates, such as PP, PET, aluminium foil, etc., are used for soft packaging materials, which are characterised by being light, elastic and soft. Traditional gravure printing is confronted with high plate-making costs and long cycles for small batch demand. Colour UV inkjet printers remove the need for plate making and allow for variable data printing and efficient order change. The equipment may be directly linked to the packaging line and spray printed with variable patterns, shelf life or batch numbers before bag making or filling. The printing speed can reach up to 30 meters per minute. The cured ink layer is scratch-resistant and water-resistant, meeting the needs of cold chain transportation and shelf display. In soft packaging niche markets such as colour box packaging, zipper bags and self-supporting bag packaging, UV inkjet technology is gradually replacing traditional gravure printing methods.

Personalising gifts and promotional items. The materials are mainly plastic, metal or wood and include lighters, thermos cups, keychains, pens, USB drives and many other advertising and promotional items. The colour UV inkjet printer can print directly on the surface of workpieces less than 10 centimetres in thickness. It is able to print full-colour patterns, brand logos and variable numbers at the same time. The device has visual recognition and locati0n functions, and can accurately locate irregular products without complex mould fixtures, achieving mass customisation production. This device can help gift customisation companies to develop a short version, zero inventory on-demand production model to offer high-end premium services.

Colour UV inkjet printers provide a complete solution for customised production, massive data management, quality assurance and production line automation in the food packaging, labelling, electronic peripherals and travel and gift industries. The device supports multi-step process integration from single printing to backend RFID, which can effectively help enterprises reduce secondary processing steps and realise cost reduction and efficiency improvement. Thanks to the benefits of inkjet manufacturing in Shenzhen, China, colour UV inkjet printers are supporting a growing number of overseas packaging and printing companies, labelling factories and product manufacturing enterprises around the world with their mature technology platform, robust structural design and extensive industry experience.
