A-SUB is a digital-printing and heat-transfer materials brand best known for its dye-sublimation transfer paper. The brand serves the personalized apparel, promotional-products, craft, signage, and digital-printing markets, offering consumables and equipment used to transfer printed designs onto textiles and hard substrates. According to the company, A-SUB has been operating in the industry since 2005 and has more than 20 years of experience. 1

A-SUB identifies ASUB PTE. LTD. as an enterprise engaged in the R&D, production and sales of personalized digital-printing and transferring products. The company says its flagship brand is A-SUB and that it currently operates four factories in mainland China, with offices in the United States and United Kingdom.

A-SUB states that its business dates back to 2005, giving it more than two decades of experience in sublimation and digital-transfer products. The company’s own materials describe it as a manufacturer and supplier serving the personalized-printing industry worldwide.

Its development has largely followed the growth of the custom-printing and sublimation industry. Rather than focusing exclusively on finished consumer products, A-SUB’s core business is supplying the materials required to create personalized products.

The company’s portfolio has subsequently expanded beyond sublimation paper into areas including DTF (Direct-to-Film) film, heat-transfer paper, sublimation ink, heat-transfer vinyl, stickers, photo paper, printable materials and sublimation blanks.

A-SUB’s current corporate materials report approximately 35,000 ft² of workshops, 25 years of experience, more than 1,500 products and 50+ local agents. These figures are company-reported rather than independently audited figures.

A-SUB’s central business is transfer media for digital printing.

The most important product category is sublimation transfer paper. In a typical sublimation workflow:

1. A design is printed onto specially coated sublimation paper using sublimation ink.
2. The printed paper is positioned against a suitable substrate.
3. A heat press applies heat and pressure.
4. The sublimation dye turns into a gas and transfers into the receiving material.
5. The finished substrate retains the transferred image.

This process is particularly common for customized polyester garments, mugs, tumblers, aluminum panels, plaques, puzzles, mouse pads and other specially coated products.

A-SUB itself recommends sublimation paper primarily for light-colored polyester textiles and compatible hard substrates.

1. Sublimation Paper

This is the product category most strongly associated with A-SUB.

The company sells several grades designed for different printing requirements. Examples include:

• 105G Universal Sublimation Paper
• 120G High-Flatness Sublimation Paper
• 125G Vivid Sublimation Paper
• 113G High-Ink-Coverage Mug Paper

A-SUB positions its 125G paper around characteristics such as vivid colors, strong ink absorption, line sharpness and high transfer performance.

Different paper weights are intended to address different use cases. For example, lighter papers can be easier to wrap around certain products, while heavier papers can provide additional stiffness and handling characteristics.

2. Sublimation Ink

A-SUB also sells sublimation ink, designed to work with sublimation-printing workflows.

Sublimation ink is fundamentally different from ordinary inkjet ink. It contains dyes formulated to transfer into suitable polyester or polymer-coated substrates when heated.

The company promotes an integrated ecosystem consisting of sublimation paper + sublimation ink + sublimation blanks + heat-transfer equipment.

3. DTF Film

A-SUB has expanded into DTF (Direct-to-Film) printing.

DTF printing involves printing an image onto a special film, applying adhesive powder and then transferring the design onto fabric with heat.

The company also promotes an A-SUB product called DTF HACK, which is designed around the use of sublimation/pigment/dye printing workflows with its DTF film.

4. Heat-Transfer Paper

A-SUB produces transfer papers for applying printed graphics to garments.

Its product range includes papers intended for:

• Light-colored shirts
• Dark-colored shirts
• Cotton garments
• Other heat-transfer applications

Unlike conventional sublimation, which works particularly well with polyester, heat-transfer paper can be used for applications where conventional sublimation isn’t appropriate. 3

5. Printable Vinyl and HTV

A-SUB’s newer product ecosystem includes heated/heat-transfer vinyl and printable vinyl materials.

These products are intended for custom apparel and craft applications, particularly when users want to cut or transfer designs rather than relying solely on sublimation.

Its resource center lists A-SUB Sublimation HTV, printable vinyl and related materials.

6. Stickers and Decal Materials

The company also sells various printable materials for stickers, decals and labels.

Examples include:

• Printable sticker paper
• Sublimation stickers
• Waterslide decal paper
• Vinyl sticker materials
• Cup-wrap materials

This represents an expansion from A-SUB’s original sublimation-paper identity toward a broader DIY personalization ecosystem.

7. Photo and Digital-Printing Paper

A-SUB also manufactures/sells various digital-printing papers, including:

• Photo paper
• Tear-proof photo paper
• Tracing paper
• OHP film
• Cold laminating film
• Acid-free photo paper
• RC photo paper
• Cardstock
• Plotter paper

These products broaden the company beyond apparel decoration into general digital-printing applications.

8. Sublimation Blanks

A-SUB has increasingly moved toward supplying the substrates onto which customers transfer their designs.

Its catalog includes items such as:

• Tumblers
• Mugs
• Puzzles
• Slates
• Photo panels
• Cup blanks
• Other sublimation-ready products

This gives A-SUB a more complete position in the personalized-goods supply chain.

A-SUB places considerable emphasis on its paper-manufacturing and coating technology.

According to its company profile, the brand uses specially selected base paper and a microporous coating technology. The coating is designed to absorb sublimation ink quickly and evenly while supporting rapid drying and efficient dye transfer. 2

The company describes its coating technology as having been continuously developed and upgraded through an R&D team involving more than 10 key personnel and more than 40 technicians.

Its manufacturing information also describes:

• Multiple coating production lines
• Rewinding machines
• Cutting machines
• Fine-cutting equipment
• Raw-material inspection
• Coating inspection
• Dimensional-tolerance inspection

A-SUB says its QC process checks the material from the raw-paper stage through coating, cutting and final production.

A-SUB’s Sublimation Paper Technology

One of the main technical selling points of A-SUB is its microporous coating.

The basic idea is that sublimation paper needs to perform several competing functions:

Ink absorption → rapid drying → controlled ink retention → efficient dye release during heat transfer

If the coating absorbs ink too slowly, the print can remain wet and potentially smear. If it absorbs too aggressively or unevenly, color density and transfer efficiency can suffer.

A-SUB says its microporous coating uses capillary forces to draw ink into the coating, allowing relatively high ink coverage while maintaining fast drying and reducing problems such as excessive bleeding.

This technology is one of the reasons A-SUB has become particularly associated with high-volume sublimation printing.

Quality control is a major part of A-SUB’s positioning.

The company’s published manufacturing information describes inspection of the base paper before it enters the coating process. It also specifies tolerances for coating quantity, paper dimensions and cutting quality.

A-SUB says its sublimation products have obtained certifications including CE, FSC and SGS-related certification/testing, although the exact certification should be evaluated on a product-by-product basis rather than assuming every A-SUB product carries all three.

A-SUB positions itself as an international rather than purely domestic Chinese supplier.

The company states that its corporate entity is based in Singapore, while manufacturing is conducted through facilities in mainland China. It also identifies offices in the United States and United Kingdom.

The brand sells through multiple channels, including direct sales, distributors and online retail.

Its company site specifically promotes an authorized distributor network and wholesale/distributor programs.

A-SUB’s customers can broadly be divided into several groups:

• Sublimation printing businesses
• Custom T-shirt businesses
• Print shops
• Promotional-product manufacturers
• Craft businesses
• E-commerce sellers
• Personalized-gift businesses
• Graphic designers
• DIY hobbyists
• Wholesale distributors

The brand is particularly relevant to the small-business and home-production market, where users may purchase packs of sublimation paper and use relatively compact desktop sublimation printers and heat presses.

A-SUB’s strongest market identity is sublimation paper, rather than printers themselves.

This is important because the sublimation ecosystem consists of several separate components:

Printer → sublimation ink → sublimation paper → heat press → blank substrate

A-SUB primarily occupies the consumables/materials portion of this chain.

Its strategy has increasingly expanded toward becoming a one-stop personalization supplier, supplying not just paper but also inks, films, transfer materials, blanks and equipment.

A-SUB has developed a significant following among sublimation users, especially in the DIY and small-business community.

Its own website publishes customer testimonials highlighting:

• Color accuracy
• Sharpness
• Ink handling
• Reduced printing problems
• Transfer quality
• Product durability

These are company-published testimonials and should therefore be treated as marketing material rather than independent statistical evidence. 4

Independent reviews have also generally treated A-SUB as an established sublimation-paper brand. For example, The Gadgeteer reported using A-SUB paper for sublimation and reviewed several of its paper products. 5

A-SUB products can be used to create a wide variety of personalized products.

Apparel

• T-shirts
• Sportswear
• Jerseys
• Polyester clothing
• Bags
• Other polyester textiles

Drinkware

• Mugs
• Tumblers
• Cups
• Water bottles

Hard goods

• Aluminum panels
• Photo plaques
• Puzzles
• Slate products
• Keychains
• Signs

Crafts

• Stickers
• Decals
• Cup wraps
• Labels
• DIY decorations
• Personalized gifts

The exact material compatibility depends heavily on the particular A-SUB product. For example, standard sublimation paper is not a universal solution for every fabric; A-SUB itself distinguishes between sublimation paper, shirt transfer paper, DTF film and HTV depending on the fabric and application.

A-SUB essentially operates as a B2B + B2C digital-printing materials company.

B2B

The company supplies:

• Wholesale customers
• Distributors
• Printing businesses
• Resellers
• Commercial personalization companies

A-SUB publishes wholesale and distributor information and states that its usual wholesale MOQ is around 50 boxes, although this varies depending on the products ordered.

B2C

A-SUB also sells individual consumer-oriented packs through its online storefronts, targeting hobbyists and small businesses.

This dual model allows the brand to serve both a person printing a few T-shirts at home and a larger commercial reseller purchasing transfer materials in bulk.

A useful way to describe A-SUB’s positioning is:

A specialist digital-printing materials brand focused on making professional-quality sublimation and personalization accessible to small businesses, creators and industrial users.

Its competitive proposition is built around four major themes:

• Print quality
• Transfer efficiency
• Product variety
• Value for money

Rather than competing primarily on the ownership of printing hardware, A-SUB competes on the quality and breadth of the materials used inside the printing workflow.

An interesting point for anyone researching the company is that A-SUB and Koala appear in the same broader printing-materials ecosystem.

Independent coverage has described the same company as producing A-SUB sublimation paper and Koala printable sticker materials. 5

However, it is better not to automatically treat the two consumer brands as identical. A-SUB’s official corporate information specifically identifies A-SUB as the flagship brand of ASUB PTE. LTD.

Based on the company’s product portfolio and available independent coverage, A-SUB’s main strengths include:

• Strong specialization in sublimation
• Large sublimation-paper range
• Multiple paper weights and formats
• Expansion into DTF and other transfer technologies
• International distribution
• Products aimed at both hobbyists and commercial users
• Broad personalization ecosystem
• Long operating history according to the company
• Strong brand recognition among sublimation users

The breadth of products is particularly notable: A-SUB is no longer simply a “sublimation paper company”; it increasingly presents itself as a broader custom-printing solutions provider. 5

As of 2026, A-SUB’s official product ecosystem spans much more than its original core identity of sublimation paper.

Its current portfolio includes:

Sublimation paper → sublimation ink → sublimation blanks → DTF film → transfer paper → HTV → printable vinyl → stickers → photo paper → digital-printing media → heat-press equipment.

The company is also investing heavily in online education and support. Its website provides user manuals, ICC profiles, templates, tutorials, SVG files, product guides and instructional content, indicating that the brand increasingly positions itself as an ecosystem rather than merely a consumables manufacturer.

A-SUB is a Singapore-based digital-printing materials brand operated by ASUB PTE. LTD., established in 2005 according to the company, best known internationally for sublimation transfer paper and now offering a broader range of sublimation, DTF, heat-transfer, sticker, photo-printing and personalization products for professional printers, small businesses and DIY creators.
