When speaking to users of dye sublimation technology, you find it can mean drastically different advantages to different businesses. To some, it means the ability to produce high-value, photo gift products. To others, it means styling custom performance apparel where the entire garment – from neck to hem – can be a zone for sublimation decoration. Hundreds of other businesses use dye sublimation in unique ways. Arguably the most versatile technology available to the product decorator today, sublimation allows for the creation of thousands of full-color, true photo quality products in numerous markets such as apparel, gifts, awards and recognition, promotional products, signage, recognition pieces, tile murals and much, much more. Whatever your business' primary focus, dye sublimation allows for a wide interpretation of product solutions across many market segments.
When investigating the products and equipment for the first time, businesses seem to have the usual questions: How does the dye sublimation process work? What types of products can be decorated? What equipment makes up a sublimation system?
Before we explore these answers, we need to know exactly what is meant by the term dye sublimation? Other decorative technologies such as rotary engraving, screen printing and embroidery are part of the general lexicon. Most everyone you speak with has some idea of what each of these technologies entails if only on a basic level. Even vinyl cutting and laser engraving are somewhat intuitive. Unfortunately, the term sublimation not only describes a decorating technology, it also describes a scientific process.
Looking at the literal meaning – as it is defined in the science world – sublimation is the phase transition of a substance from a solid directly to a gas without going through a liquid phase occurring under specific temperature and pressure conditions.
OK. But how does this fit in to decorating thousands of products with a photo quality image? It helps if you approach this technology by looking first at the word dye. This technology involves a dye process. Hundreds of thousands of everyday products are decorated using colored dyes. Manufacturers of apparel, consumer packaging, consumer goods, electronics, etc., et al add dyes to color their products whether they're made of plastics, fabrics or woods. The dye process is often done at early stages before the individually decorated product components are assembled or sewn together.
As we are describing dye sublimation, the "solid" part of the equation denotes the microscopic particles of solid ink dyes which rest on the surface of your printed, ready-to-transfer sublimation page which you printed directly from CorelDRAW, Adobe PhotoShop or a rip program like Wasatch to a supported Epson, Ricoh, Mutoh or Mimaki sublimation printer. When introduced to heat, these solid ink particles turn directly to a gas which then permanently dye the decorated surface and sub-surface of your product, depending on whether it’s a textile or hard substrate.
The first steps of sublimation decoration often involve the same tools used with other technologies like engraving, screen printing and embroidery. It is only after the final image is printed to paper when sublimation sets itself apart from all other technologies.
Here's the step-by-step process required to produce a sublimated product:
In order to determine whether you can imprint a product with a wash-fast, scratch-resistant, full-color sublimation image, you'll need to check three items: First, is the decoration area polyester-based? Sublimation is reliant on polyester's unique molecular structure (e.g. its ability to bond with the gassed ink dyes). You can not sublimate to cotton, nylon, vinyl, wool, leather, etc. Second, will the product hold up to the optimal temperatures (up to 400° F) and pressure required for the dye sublimation process? Lastly, is the color of the product light enough to take an image? Because this is a dye technology, the color of a sublimation product's decoration surface can affect the final colors of your graphic. True white works best, but you can still decorate lighter colored products such as t-shirts or sand-colored stone tiles while achieving 70-80% of the printer's available color gamut.
There are hundreds of ready-to-sublimate products specifically made for the sublimation industry with more and more being introduced continually. There are products for practically every business market. On the awards and recognition side, sublimation allows for full-color, photo quality plaques, signs, name badges and other identification products. The apparel side offers variety and option for the decorator from trendy hooded sweatshirts to engineered, microfibers. Not only will a sublimated image never wash away, but sublimation is the only imprinting technology which doesn't impede the wicking process in performance apparel, allowing you the ability to market customization to the "Under Armour" crowd. On the gift side, what better way to personalize a product than with a photograph realistically recreated on a quality wooden box, coffee mug or other personal item? The promotional industry loves sublimation for the "higher quality" promo products that make a bigger advertising splash due to the full color graphics. The list goes on.
In addition to the ready-made products, you can purchase polyester-coated sheets of masonite, fiberglass-reinforced plastic and metal which can be cut down to create unique shapes and sizes. By sublimating to raw, polyester fabric in dozens of styles, end users develop their own unique cut-and-sew products from custom soft signs to sports jerseys to high-end fashion.
A sublimation system comes in a variety of configurations depending on the decorator’s product offerings and production volume. There are five main components to a typical sublimation system.
Savvy business owners have long exploited the versatility of dye sublimation. It’s not unusual for sublimation users to make a variety of special products to satisfy an individual customer’s diverse needs. Whether it’s providing interior signage, full color plaques or promotional goods, a single vector logo delivered to a digital decorator can yield hundreds of individually customized, sublimation products. Furthermore, digital decorators from other industries like engraving and embroidery are finding that they can target entire new market segments merely by adding a sublimation system.
