Inkjet

Types of Ink Jet Printer

Inkjets are classified as Industrial Inkjets and Commercial Inkjets, amongst others. They also differ on the basis of the kind of inks they use and the resultant outcomes. This categorization is based on factors such as production volume requirements, component size, operating constraints, and additional parameters. Common types include conventional inkjet, UV inkjet, modified inkjet, food inkjet, etc. Conventional inkjet printers use liquid ink, which is often absorbed by the substrate. The droplet size typically ranges between 10 to 80 picoliters. These devices are mainly employed for low to medium production and grant impressive quality. The printers work with different inks, including dye-based, pigment-based, and others.

Conversely, UV inkjet printers use ultraviolet light to solidify, cure, or set the ink. This process provides a robust, long-lasting print that is usually more resistant to fading and scratching than conventional inkjet prints. The ink is mainly printed as a liquid and is subsequently cured. UV printers are primarily found in Industrial Inks because they are robust and effectual in large constructions.

Thermal inkjet printers utilize heating elements to generate the inkjet. This process creates vapor bubbles that propel droplets of ink onto the printing surface. The technology is predominant in consumer inkjet printers for home use and in small offices. The Modified inkjet mirrors the normal inkjet process but offers for larger ink droplet sizes, often in a range between 50 and 2000 picoliters. It is primarily engaged and integrated into industrial printing applications, particularly for variable data printing. In this technology, larger ink droplets ensure embossing or raised prints on surfaces for applications such as packaging.

Lastly, food inkjet printing utilizes food-safe inks to print edible images and designs on baked products, confectionaries, and other food items. The inks are primarily sourced in compliance with food safety standards. This assists in product decoration, packaging, and enhancement of visual appeal through edible printing. The pud ink for cake printing used for food inkjet printing is ink created using talented edible materials such as dyes or pigments legally deemed safe for consumption.

Industrial Applications

Here are the industrial applications of ink types, including ink for food cakes, industrial graphics, electronics imprinting, packaging, labels, etc.

• Packaging and Labeling

  In the packaging industry, including food packaging, there is a volatile and competitive environment. Companies often rush to meet consumer demands. Quick and high-quality printing on flexible materials such as films, papers, and labels is essential.

  Additionally, digital printing technologies such as inkjet make it possible to do short runs economically, especially for products with seasonal labels, limited editions, or varying sizes. Inkjet printing preferentially uses quick-set UV inks that adhere effectively to non-porous packaging substrates.

• Commercial Printing

  High-volume tasks such as catalog production or flyer and brochure printing require systems that can handle large loads of paper daily. Therefore, offset printing has traditionally been the technique of choice for such applications due to its printing process economy on larger jobs.

  As technology has progressed, inkjet presses have gradually taken over the market. This is especially true for segments such as direct mail printing, where the personalization of items at high speed and low cost is beneficial. Those mailers offering customized messages in every envelope favor high-speed inkjet as they provide variable data capabilities insufficiently addressed by offset.

• Industrial Graphics and Signage

  The demand for grand format printing within the commercial signage market and graphic and graphical displays is addressed through wide-format inkjet technologies. They allow fast and compatible printing of surface and non-surface materials of differing dimensions, including vinyls, fabrics, and rigid boards.

  Inkjet has virtually replaced solvent and latex printers as the technology of choice for its low-noise printing, eco-friendly inks, and optimal color accuracy. It is perfect for applications that require outdoor durability and vibrant color displays. For instance, billboards, banners, and vehicle wraps.

• Decorative Printing

  Decorative tasks include surface printing for floors, walls, and home textiles. It has witnessed a constant transformation under the effects of inkjet technologies. Digital printers can reproduce highly intricate patterns on materials such as ceramic tiles, wallpaper, and fabric.

  The adjustable nature of digital printing allows designers to test numerous prints without placing huge print runs. This is problematic for the decorative industry, where styles quickly shift and consumer demand often changes.

• 3D Printing

  3D printing within additive manufacturing has incorporated inkjet techniques mainly in the creation process. Binder jetting, one of the principal processes, uses droplets of liquid binding material to impregnate powder substrates selectively. This allows for the construction of full three-dimensional entities layer by layer.

  Inkjet and this technology have enabled the rapid prototyping and manufacturing of goods in various industries ranging from automotive to healthcare. With this, complex geometries and light structures can be produced, giving rise to the increasing appeal of 3D printing and efforts to meet customer demands and sustainability concerns.

Product Features and Specifications

When selecting inkjet printers for various applications, there are key features that should be considered. These features significantly impact print quality, speed, media compatibility, and the total cost of ownership. Some of these considerations are given below.

• Print Head Technology

  Ink droplets must be accurately controlled in the production of high-value printed goods. This control is achievable through precise print heads.

  Micro piezo print heads emit ink through a piezoelectric mechanism. It applies variable voltage to ink-filled chambers. This enables the chambers to generate pinhole-sized droplets desired for printing high-resolution images.

  Conversely, thermal print heads utilize heat generated on-demand to form ink bubbles. The bubbles cause the ink to expel through tiny orifices. This method is mainly used in consumer inkjet printers and is comparatively inexpensive. However, the print heads are less durable than the micro piezo counterpart.

• Ink Types and Drop Size Variability

  A characteristic feature of modern inkjet printers is the ability to vary the ink droplet size. This attribute has great significance for production.

  Droplets of different volumes ranging from small for printing high-resolution images to larger for laying low-cost colors are a possibility. This enhances color depth while increasing efficiency.

  Subsequently, such printers are able to effectively utilize multiple ink sets consisting of different-colored inks with various droplet sizes. It results in more vibrant colors and smoother gradations.

• Print Production Capabilities

  For various food industries, the performance of inkjets in paginating certain products, such as cake tops and other food decoration activities with high efficiency, becomes critical.

  Commercialized inkjet printers can operate at varying speeds, typically between 10 to 200 meters per minute, depending on the application. This is a major printer's value, especially in industries where time is money. This value is primarily affected by print head type, media used, and attachment features like drying systems.

• Media Compatibility

  Flexible inkjet printing machines have versatility in the media they can handle. These include standard porous substrates such as paper and textiles and non-porous materials like plastic films and metal. They tackle such diversity through tailored inks and print heads appropriate for each medium.

  Ink choice and print head design affect the quality and durability of the products printed. Therefore, new manufacturing standards require compatibility with multiple substrates.

• Industrial Inkjets vs. Modified Inkjets

  Industrial Inkjets are specialized for high production rates in large-scale manufacturing processes. These printers are robust and built for continuous operation, utilizing advanced print head technologies for precise ink deposition.

  On the other hand, modified inkjets are often used for specific applications. Such applications include custom packaging or variable data tasks. These printers offer flexibility but typically do not match the output levels found in industrial settings.

How to Choose
