DTF Ink vs Sublimation Ink vs DTG and UV Ink: Key Differences
Ink is not simply a colored liquid added to a printer.
Every printing process requires an ink formulation designed for a specific printhead, printing surface, curing method and production workflow. DTF ink, sublimation ink, DTG ink and UV ink may all produce full-color images, but they cannot be used interchangeably.
Using the wrong ink can cause:
Poor color output
Weak adhesion
Printhead clogging
Ink separation
Failed curing
Damaged ink lines
Short product life
Permanent printer damage
For a custom printing business, choosing the correct ink is therefore just as important as choosing the printer itself.
This guide explains how the main types of digital printing ink work, which materials they support, why white ink requires special maintenance and why printer ink, media, RIP software and color profiles must be treated as one complete system.
Printer Ink Types at a Glance
| インクの種類 | Main printing process | Typical colorant or curing method | 最高のアプリケーション |
|---|---|---|---|
| DTFインク | Direct-to-film transfer | Heat-transfer pigment ink | Cotton, polyester, blends and dark apparel |
| 昇華インク | Dye-sublimation transfer | Disperse dye | Polyester and polymer-coated products |
| DTG ink | Direct-to-garment printing | Water-based pigment ink | Cotton garments and selected treated fabrics |
| UVインク | UV flatbed and UV DTF printing | UV硬化型インク | Acrylic, glass, metal, plastic, wood and coated surfaces |
| Standard dye ink | Documents and photographs | Water-soluble dye | Paper and photo media |
| Standard pigment ink | Documents and fine-art printing | Pigment particles | Paper, labels and archival prints |
| Solvent ink | Sign and graphics printing | Solvent-carried colorant | Vinyl, banners and outdoor signage |
The four most relevant types for a personalized printing business are DTF, sublimation, DTG and UV ink.
What Is Printer Ink Made Of?
Although formulations differ, inkjet ink usually contains several functional components.
Colorant
The colorant creates the visible color.
It may be:
Pigment particles
Dissolved dyes
Disperse dyes
UV-curable color components
Pigments remain as very small solid particles in the formulation. Dyes are dissolved or dispersed and interact differently with the final material.
Carrier Liquid
The carrier helps move the ink through the ink system and printhead.
Depending on the ink technology, the carrier may be primarily:
Water
Solvents
Glycols
UV-curable liquid components
Binder or Resin
Binders help the colorant attach to the printing surface.
They influence:
接着力
柔軟性
Gloss
Scratch resistance
耐洗濯性
表面感
Additives
Additives control properties such as:
Surface tension
Viscosity
Drying behavior
Foam control
Ink flow
Storage stability
Nozzle performance
Small formulation differences can significantly affect how an ink behaves inside a printhead. This is one reason inks from different systems should not be mixed casually.
What Is DTF Ink?
DTF ink is designed for direct-to-film transfer printing.
The ink is printed onto a specially coated PET film rather than directly onto the garment. After printing, hot-melt adhesive powder is applied and cured. The completed design is then transferred to the fabric using a heat press.
Professional DTF systems commonly use five ink channels:
シアン
マゼンタ
黄色
黒
白
How DTF Ink Works
一般的な DTF ワークフローには次のものが含まれます。
Printing the color layer onto coated PET film
Printing a white ink layer
ホットメルト接着剤パウダーの塗布
Curing the powder
Positioning the transfer on the garment
Heat pressing the transfer
キャリアフィルムを剥がす
Completing a finishing press when required
The ink, film, adhesive powder and pressing conditions must work together.
You can learn more about the complete material system in EraSmart’s DTF 消耗品ガイド。
What Materials Can DTF Ink Print?
DTF transfers can commonly be used on:
コットン
ポリエステル
綿とポリエステルの混紡
キャンバス
フリース
デニム
軽装
暗い色の衣服
The white ink underbase allows the color layer to remain visible on black, navy, red and other dark fabrics.
Advantages of DTF Ink
DTF ink supports:
Full-color graphics
White printing
Dark garment decoration
細かい部分
Small-batch production
Multiple fabric types
Custom gang sheets
Flexible apparel workflows
Limitations of DTF Ink
DTF ink also introduces several challenges:
White ink requires circulation and maintenance.
Ink must match the PET film and powder.
Incorrect curing can weaken adhesion.
Poor-quality ink may increase nozzle problems.
Large solid designs may produce a more noticeable surface feel.
The printer should not remain idle without proper maintenance.
What Is Sublimation Ink?
Sublimation ink is a dye-based ink formulated for heat transfer onto polyester or polymer-coated products.
The design is first printed onto sublimation paper. During heat pressing, the disperse dye becomes mobile and enters the polyester fiber or compatible coating. After cooling, the color becomes part of the material.
How Sublimation Ink Works
The basic process includes:
Printing a mirrored design onto sublimation paper
Positioning the paper on the product
Fixing it with heat-resistant tape
Applying the required heat, time and pressure
Removing the transfer paper
Allowing the product to cool
The exact pressing conditions depend on the ink, paper, blank, coating and heat press. There is no single universal setting for every sublimation product.
What Materials Can Sublimation Ink Print?
昇華は次の場合に最適に機能します。
白いポリエステルシャツ
Light-colored polyester garments
Coated ceramic mugs
コーティングタンブラー
マウスパッド
Phone case inserts
ポリエステル枕カバー
Coated aluminum panels
キーホルダー
コースター
Photo gifts
Why Sublimation Does Not Work Well on Cotton
Sublimation dye needs polyester or a compatible polymer coating.
Ordinary cotton does not provide the same dye-binding structure. A sublimated design on untreated cotton may appear weak and may not provide acceptable wash durability.
Why Sublimation Is Limited on Dark Products
Sublimation ink is transparent and normally does not include white ink.
The color of the product remains visible underneath the design. This is why sublimation performs best on white or light surfaces.
Advantages of Sublimation Ink
Sublimation can provide:
滑らかな勾配
Photo-quality output
No raised transfer layer
Strong durability on compatible materials
Full-color gift products
Low material consumption
Easy personalization
Limitations of Sublimation Ink
Its limitations include:
Restricted material compatibility
Poor visibility on dark products
No white ink
Dependence on coating quality
Potential ghosting if paper moves
Color variation caused by incorrect ICC profiles or pressing conditions

DTF Ink vs Sublimation Ink
DTF and sublimation are both heat-transfer processes, but the inks behave differently.
| 比較 | DTFインク | 昇華インク |
|---|---|---|
| Ink category | Heat-transfer pigment ink | Disperse dye ink |
| Printing medium | Coated PET film | 昇華紙 |
| 白インク | はい | いいえ |
| 接着剤粉末 | 必須 | 必要ありません |
| Best fabrics | 綿、ポリエステル、混紡 | ポリエステル |
| 暗い色の衣服 | Suitable | Generally unsuitable |
| Coated hard products | 限定 | Highly suitable |
| 表面感 | 転写層が残る | Dye becomes part of the material |
| Printer maintenance | Higher because of white ink | Generally lower |
| Main products | 衣服 | Apparel and personalized gifts |
The correct choice depends more on the product than on which ink is “better.”
Choose DTF for dark cotton apparel, hoodies, uniforms and tote bags. Choose sublimation for polyester garments, mugs, mousepads and coated photo gifts.
What Is DTG Ink?
DTG stands for direct-to-garment printing.
Unlike DTF, DTG ink is printed directly onto the garment. The printed fabric is then heat-cured to fix the ink.
DTG systems commonly use water-based pigment inks in:
シアン
マゼンタ
黄色
黒
白
How DTG Ink Works
A typical DTG workflow includes:
Preparing the garment
Applying pretreatment when required
Drying or pressing the pretreatment
Loading the garment onto the platen
Printing directly onto the fabric
Heat curing the printed garment
Best Applications for DTG Ink
DTG is commonly used for:
Premium cotton T-shirts
Detailed artwork
Photographic shirt printing
One-off custom garments
Small-batch fashion products
Designs requiring a softer feel on cotton
DTF Ink vs DTG Ink
| 比較 | DTFインク | DTG ink |
|---|---|---|
| Printed onto | ペット映画 | 衣服 |
| 接着剤粉末 | 必須 | 必要ありません |
| Pretreatment | Usually not applied to the garment | Often required |
| Fabric range | Broad | Strongest on suitable cotton |
| ワークフロー | Transfer production and pressing | Direct printing and curing |
| Storage of prints | Transfers can be produced in advance | Garment is printed directly |
| Fine cotton feel | 良い | Often softer on suitable garments |
You can explore the differences further in EraSmart’s DTG printer vs DTF printer guide。
What Is UV Ink?
UV ink is designed to cure under ultraviolet light.
Instead of drying primarily through evaporation or being heat-transferred into a fabric, UV-curable ink changes into a solid printed layer when exposed to the printer’s UV LED lamps.
Mimaki explains that UV ink cures and adheres directly to the substrate under UV radiation. UV systems can print on non-absorbent materials such as plastic, glass and metal, and different hard or flexible formulations are available for different applications.
Common UV Ink Channels
A UV printer may use:
シアン
マゼンタ
黄色
黒
白
Varnish or clear ink
Primer in supported systems
Light cyan and light magenta in some configurations
What Can UV Ink Print?
Depending on the printer and fixture, UV ink may be used on:
アクリル
ガラス
金属
木材
プラスチック
レザー
セラミック
電話ケース
販促品
Signs
パッケージング
フラットパネル
White UV Ink
White UV ink can be used as:
An underbase beneath color
A backing layer on transparent material
A standalone white design
Part of multilayer printing
Varnish Ink
Clear or varnish ink can create:
Gloss effects
Spot highlights
Textured surfaces
Raised details
Protective visual effects
Read EraSmart’s UV ink guide for CMYK, white and varnish for a more detailed explanation.
UV Ink vs DTF Ink
DTF and UV printing are designed for different product categories.
| 比較 | DTFインク | UVインク |
|---|---|---|
| Primary products | Fabric and apparel | Hard and semi-rigid products |
| 硬化方法 | Powder curing and heat pressing | UV LED curing |
| Transfer medium | ペット映画 | Usually direct printing |
| 白インク | はい | Commonly available |
| ワニス | Normally no | Available on supported systems |
| Cotton garments | Suitable through transfer | Generally not the main application |
| Acrylic and metal | Not the main use | Suitable |
| 表面感 | Flexible transfer layer | Cured ink film |
UV DTF is a separate process that uses UV ink to print onto an adhesive film system before transferring the graphic to a hard product.
To avoid confusing these technologies, see UV DTF vs textile DTF vs UV flatbed printing。
Why White Ink Requires More Maintenance
White ink behaves differently from standard CMYK ink.
White formulations contain dense pigment to create opacity. These particles are more likely to settle when the printer remains idle or when the ink is not circulated correctly.
Potential problems include:
Reduced white density
Nozzle loss
Ink separation
Uneven underbase
White ink mist
Deflected droplets
Clogged ink paths
Printer manufacturers therefore use features such as:
白インクの循環
Automatic stirring
Scheduled head refresh
Cartridge or ink-pack agitation
Guided cleaning cycles
The correct procedure depends on the printer model. Follow the machine manual rather than applying a generic maintenance schedule.
For practical prevention steps, read how to prevent white ink clogging。
Why Different Printer Inks Cannot Be Mixed
Two ink bottles may appear to contain the same CMYK colors, but their formulations may differ in:
Viscosity
Surface tension
Pigment size
Dye concentration
Resin chemistry
Drying behavior
Curing requirements
pH
Printhead compatibility
Mixing incompatible inks may cause:
Chemical reactions
Sediment
Gel formation
Ink separation
Color shifts
Blocked dampers
Damaged printheads
Unstable white ink
Never combine:
DTF ink and sublimation ink
UV ink and water-based ink
DTG ink and UV ink
Cleaning solution and ink without an approved procedure
Different brands merely because the colors appear similar
Even two products labeled “DTF ink” may not be suitable for mixing.
Before changing ink, confirm whether the printer requires:
Complete draining
Flushing solution
New dampers
New ink lines
New ICC profiles
Printer recalibration
EraSmartの DTF インク互換性ガイド explains the checks that should be completed before switching ink.
How Ink Affects the ICC Profile
An ICC profile or RIP ink curve controls how color data is converted into printer output.
The final result depends on the combination of:
プリンター
プリントヘッド
インク
メディア
解決
Pass mode
白インクの濃度
RIP設定
Curing or pressing conditions
Changing the ink can change:
色の濃さ
Gray balance
Total ink limit
Black generation
Saturation
Drying behavior
White underbase requirements
A profile created for one ink, film and printer combination may not reproduce the same colors after any component is changed.
This is why apparently identical CMYK values can produce different printed results.

Should You Always Use Manufacturer-Matched Ink?
A matched ink system usually provides the lowest operational risk because the printer, ink delivery system, RIP profile and maintenance procedure have been tested together.
This can help improve:
色の一貫性
Nozzle stability
White ink performance
接着力
テクニカルサポート
トラブルシューティング
Warranty clarity
The lowest-priced ink is not necessarily the lowest-cost ink to operate.
A cheaper bottle can become expensive if it causes:
Failed prints
Wasted film
Damaged garments
Excessive cleaning
Shortened printhead life
Production downtime
Evaluate ink by total production cost rather than bottle price alone.
最終的な考え
DTF, sublimation, DTG and UV ink are different chemical and production systems.
DTF ink is a heat-transfer pigment system designed for PET film, adhesive powder and fabric pressing.
Sublimation ink uses disperse dye to color polyester fibers and polymer-coated products.
DTG ink is printed directly onto prepared garments and then heat-cured.
UV ink cures under UV LED light and creates a durable printed layer on many rigid or non-absorbent materials.
None of these inks should be substituted based only on color or appearance.
Before purchasing ink, confirm:
Printer technology
Printer model
プリントヘッド
Ink channel configuration
メディア
硬化方法
RIPプロファイル
応用
Supplier support
The best ink is not simply the one that produces the brightest test print. It is the ink that provides stable jetting, predictable color, reliable adhesion and repeatable production throughout the life of the printer.

よくある質問
Is DTF ink the same as sublimation ink?
No. DTF ink is a heat-transfer pigment ink used with coated PET film and adhesive powder. Sublimation ink uses disperse dye and is transferred from paper into polyester or a polymer coating.
Can sublimation ink be used in a DTF printer?
No. Sublimation ink does not provide the white underbase, film behavior or adhesive workflow required for textile DTF production.
Can DTF ink be used for sublimation?
No. DTF pigment ink is not designed to diffuse into polyester in the same way as sublimation dye.
Is DTF ink water-based?
Commercial DTF inks are commonly formulated as aqueous heat-transfer pigment inks, but users should confirm the specification and safety data sheet of the exact product.
Why does DTF use white ink?
White ink creates an opaque underbase beneath CMYK colors, allowing designs to remain vivid on dark and colored garments.
Why does sublimation not use white ink?
Sublimation relies on transparent dyes entering polyester or a polymer coating. White areas normally come from the white product surface itself.
Why does white ink clog more easily?
White ink contains dense pigment for opacity. The pigment can settle when the ink is not circulated or agitated according to the printer’s maintenance requirements.
Can different brands of DTF ink be mixed?
Mixing is not recommended unless compatibility has been explicitly confirmed. Differences in chemistry, viscosity and pigment behavior can cause instability or printhead damage.
Does changing ink require a new ICC profile?
It often does. Different ink formulations can alter color density, gray balance, saturation and total ink limits.
Which ink is best for a small custom printing business?
Choose according to your products:
DTF for cotton and dark apparel
Sublimation for polyester and coated gifts
DTG for direct premium garment printing
UV for hard and promotional products
