An inkjet printer is a digital printing device that creates images by ejecting tiny droplets of ink onto a surface. Instead of using plates, screens, or physical stencils, an inkjet printer receives digital image data and places controlled ink droplets in precise positions to form text, graphics, photos, labels, transfers, or product decoration.
Most people first know inkjet printers from office or home photo printing. But inkjet technology is much broader than desktop paper printing. Today, inkjet systems are used in DTF printing, UV flatbed printing, UV DTF transfers, packaging samples, product labels, signage, promotional products, textile decoration, industrial marking, and custom product manufacturing.
For EraSmart customers, this topic matters because many modern custom printing machines are built on inkjet principles. A DTF принтер uses inkjet technology to print garment designs onto transfer film. A УФ-принтер uses inkjet technology to print UV-curable ink directly onto rigid materials. A УФ-принтер DTF uses inkjet printing to create hard-surface decals and transfers on A/B film.
In simple terms, inkjet printing is the foundation. DTF, UV, and UV DTF are specialized business workflows built around that foundation.
An inkjet printer is a printer that sprays or ejects tiny droplets of liquid ink through microscopic nozzles to create a printed image.
A basic inkjet printing system includes:
The printhead is the key component. It controls where ink droplets land, how much ink is ejected, and how accurately the image is formed.

Inkjet printing may look simple from the outside, but inside the printer there is a precise digital control process.
A simplified workflow looks like this:
In an office inkjet printer, ink is usually printed onto paper and dries or absorbs into the paper surface. In an industrial or custom printing system, the process may be more specialized. For example, UV ink is cured by UV light, while DTF ink is printed onto PET film and later heat transferred onto fabric.

The printhead is the most important part of an inkjet printer. It contains many tiny nozzles that eject ink droplets. The printhead determines much of the printer’s resolution, droplet control, speed, and print quality.
In custom printing, printhead condition directly affects:
This is why printer maintenance is so important in DTF and UV printing. If the printhead nozzles are clogged or unstable, the final print may show banding, missing lines, weak colors, or poor detail.
For apparel printing users, EraSmart’s Руководство по обслуживанию принтера DTF is a useful resource for understanding why nozzle checks, cleaning, white ink circulation, and daily care matter.
The ink system stores and delivers ink to the printhead. Different inkjet printers use different types of ink depending on the application.
Common ink types include:
For EraSmart customers, the most relevant ink systems are DTF ink, UV ink, white ink, and varnish.
А DTF принтер commonly uses CMYK ink plus white ink. The white ink helps designs appear clearly on dark garments. A УФ-принтер may use CMYK, white ink, and varnish to print on hard surfaces such as acrylic, glass, metal, wood, plastic, leather, and packaging materials.
If you want to understand how CMYK, white ink, and varnish work together in product customization, see EraSmart’s UV Ink Guide: CMYK, White Ink, and VarnishПолем
Nozzles are microscopic openings in the printhead. They eject ink droplets in controlled patterns.
Nozzle performance affects:
Nozzles can become clogged if ink dries, settles, or becomes contaminated. This is especially important for white ink systems because white ink contains heavier pigment particles and needs proper circulation and maintenance.
Inkjet printers need accurate motion control. Either the printhead moves across the material, the material moves under the printhead, or both are coordinated.
The motion system affects:
In UV flatbed printing, the platform and printhead movement must be stable so the image lands accurately on rigid objects. In DTF printing, film feeding must be smooth so the transfer image remains consistent.
RIP software converts artwork into printer-ready instructions. It controls color output, resolution, ink layering, white ink channels, varnish layers, print passes, and other production settings.
For custom printing businesses, RIP setup is important because it affects:
A good printer is only part of the system. Correct artwork preparation and RIP settings are also necessary for professional results.

Inkjet printing is not finished when ink leaves the nozzle. The ink must also become stable on the final product.
Different workflows use different finishing methods:
| Inkjet Workflow | What Happens After Printing |
|---|---|
| Office inkjet | Ink dries or absorbs into paper |
| DTF печать | Powder is applied, cured, then heat pressed onto fabric |
| Ультрафиолетовая печать | UV light cures the ink almost instantly |
| УФ DTF печать | UV ink is printed on film, laminated, then applied as a transfer |
| Сублимация | Printed transfer is heat pressed into polyester or coated blanks |
This is why inkjet technology can support many industries. The core droplet technology is similar, but the finishing process changes based on the product.

There are two major inkjet technologies: thermal inkjet and piezo inkjet.
Thermal inkjet uses heat to create a vapor bubble inside the ink chamber. The pressure from this bubble pushes a droplet of ink out of the nozzle.
Thermal inkjet is common in many desktop and office printers. It can produce high-quality prints on paper, but the ink must be compatible with heat-based ejection.
Piezo inkjet uses a piezoelectric element that changes shape when voltage is applied. This mechanical movement creates pressure and ejects ink droplets through the nozzle.
Piezo inkjet is widely used in many professional and industrial printing systems because it can work with a broader range of inks. Since the ink is not heated for ejection, piezo technology is suitable for inks that may not perform well in thermal systems, including many specialty inks used in industrial and custom printing.
For DTF, UV, and UV DTF applications, piezo-style inkjet technology is especially important because these workflows require precise ink control and compatibility with specialized ink types.
Inkjet printing can also be divided by how ink is delivered.
Drop-on-demand means ink droplets are ejected only when needed. This is common in many graphic and custom printing applications because it offers precise control and efficient ink use.
DTF, UV, and UV DTF printers generally operate around controlled digital droplet placement, which is why they can reproduce detailed designs and full-color artwork.
Continuous inkjet ejects a continuous stream of ink droplets. Some droplets are directed to the surface, while others may be recycled. This method is often used in industrial coding and marking, such as printing dates, batch codes, and product identification on packaging lines.
For EraSmart customers, drop-on-demand inkjet is the more relevant concept because custom apparel and product printing require accurate image reproduction rather than simple coding.
A DTF printer is a specialized inkjet printer for garment transfer production. Instead of printing directly onto a shirt, it prints the design onto PET transfer film.
The typical DTF process includes:
This process is useful for custom apparel because it supports:
If you are interested in building an apparel business, EraSmart’s DTF принтер category includes different models for startups, small studios, growing shops, and higher-volume production. You can also read the Рабочий процесс производства DTF to understand the full process from artwork to finished garment.
A UV printer is another specialized inkjet system. Instead of using standard paper ink, it uses UV-curable ink. The printer ejects ink onto the material surface, and UV light cures the ink almost immediately.
UV printing is suitable for many hard and semi-rigid materials, such as:
The advantage of UV printing is direct-to-object customization. You can print full-color designs, white ink layers, and varnish effects on many product surfaces.
EraSmart’s УФ-принтер category is designed for businesses that want to create custom gifts, signs, phone cases, packaging samples, acrylic products, and hard-surface promotional items. For material selection, see the Руководство по материалам для УФ-принтеровПолем
UV DTF printing combines UV inkjet printing with a transfer workflow. The printer prints UV ink onto A film, laminates it with B film, and creates a transfer decal that can be applied to hard surfaces.
UV DTF is useful for:
Unlike textile DTF, UV DTF is mainly for hard-surface transfers, not garments. It is a good choice for businesses that want to sell premium stickers, decals, labels, and cup wraps.
EraSmart’s УФ-принтер DTF is suitable for hard-surface transfer applications, while the A/B Film for UV DTF Printing guide explains how the film system works in the transfer process.
Inkjet printing is important because it allows digital, flexible, short-run production. Unlike traditional methods that require screens, plates, or molds, inkjet printing can print directly from a digital file.
This creates major advantages for custom businesses:
For example, a DTF apparel business can print different names, numbers, and graphics without preparing new screens. A UV printing business can print different logos on phone cases, acrylic signs, glass gifts, or packaging samples. A UV DTF business can produce custom decals and labels for many small brands.
This is why inkjet technology is no longer only about office printing. It is now a core technology for modern customization businesses.
Inkjet printing works directly from digital files. This makes it easy to change designs, personalize products, and produce short runs.
Inkjet printers can reproduce complex color images, gradients, photos, and illustrations. This is useful for apparel graphics, product decoration, stickers, and packaging samples.
Inkjet does not require plates or screens, so it is suitable for low-MOQ custom orders and on-demand production.
Each print can be different. This is useful for names, numbers, QR codes, serialized labels, personalized gifts, and custom designs.
Inkjet technology can be adapted to many surfaces and workflows, including paper, textiles, film, rigid materials, packaging, labels, and transfers.
A business can start with small orders and upgrade equipment as demand grows. This is why inkjet-based DTF, UV, and UV DTF systems are attractive to startups and growing shops.
Inkjet printers need regular maintenance. If nozzles clog, print quality declines. This is especially important for white ink, UV ink, and other specialty ink systems.
Not every ink works with every printhead or material. Ink viscosity, pigment size, curing method, and surface compatibility all matter.
Some surfaces need cleaning, primer, coating, or testing before printing. This is especially common in UV printing on glass, metal, plastic, and other hard materials.
Screen colors and printed colors are not always identical. Professional results require color profiles, test prints, correct RIP settings, and stable consumables.
Higher resolution, more passes, white ink layers, and varnish effects may improve quality but increase printing time.
In DTF printing, powdering, curing, and heat pressing affect durability. In UV DTF, lamination and application affect transfer quality. In UV printing, curing and adhesion affect final product quality.
This is one of the most common inkjet problems. It can be caused by dried ink, settled pigment, poor maintenance, incompatible ink, or long idle time.
Banding appears as unwanted horizontal or vertical lines. It can be caused by clogged nozzles, incorrect feed settings, poor calibration, or unstable ink flow.
Colors may look different from the screen because of material surface, ink type, printer profile, white ink layer, or lighting conditions.
In UV printing, poor adhesion can happen if the surface is oily, dusty, incompatible, or not treated correctly.
In DTF and UV printing, white ink must be managed carefully. Weak white ink can reduce color brightness, opacity, and dark-surface performance.
If ink is not dried, cured, or transferred correctly, the final product may smear, peel, crack, or lose durability.

The right inkjet printer depends on what you want to sell.
