Most sign industry professionals are already familiar with screen printing and digital printing to some extent, but may not be fully up to speed on the ins and outs of the dye-sublimation printing process.


Dye-sublimation printing is unique not only because of the nature of the printing process—binding the image to the surface—but also due to the wide variety of substrates that can be used including fabrics, ceramics, metals and more. Another important point about sublimation is that this kind of printing can be used across other industries such as apparel or promotional markets.


The difference with dye sublimation in the sign industry is that, “The apparel business requires more steps and more labor input to reach the final product and the promotional items are typically small items that fit in one hand. These two applications need a printer that is typically 50-inch max width,” explains Joe Garcia, managing director for the Americas, at StratoJet USA. “The sign business requires a width wide enough to fit the final sign, typically 60 inches or more. Also, in the sign business, the bottleneck is typically the printing speed; hence fast printers are paramount to the sign industry.”

StratoJet USA美洲地区的总经理Joe Garcia解释道: “与标识行业的染印升华不同之处在于,服装业务需要更多的步骤和更多的劳动力投入,才能完成最终产品,促销品通常是一方面的小件物品,一般需要宽度为50英寸的打印机。标识业务需要足够宽的宽度以适应最终标识的形成,通常需要尺寸为60英寸或更多尺寸的打印机。另外,在标识业务中,打印过程出现的瓶颈通常以速度这个因素为主,因此,快速打印对标识行业的业务至关重要。”

So, much like printing with other machines and techniques, speed is a must. But other factors come into play too such as types of ink, substrates, software and more. Maximizing all of these elements contributes to how a dye-sublimation print can succeed in the sign industry.


For sign makers who are unfamiliar with or have just started in dye-sublimation printing, there are steps to take in order to build your business. One of the most obvious is to choose the right printer.


The Printer


“First and foremost, print service providers should consider the printer they’ll be using for dye-sublimation applications,” explains Lily Hunter, product manager, textiles and consumables, Roland DGA. “It’s important to purchase a reliable, well-built sublimation printer, like a Roland Texart RT-640 or Texart XT-640.”

Roland DGA的产品经理Lily Hunter解释说:“首先,打印服务提供商应该考虑什么类型的设备适用于他们的应用,购买可靠、制造精良的升华打印机非常重要,例如像Roland Texart RT-640或Texart XT-640这样的设备。”

She says shop owners should investigate what is included in a printer purchase, and educate themselves about guarantees and printer support. “Be aware of any hidden costs, the manufacturer’s warranty and terms, the level of support you will receive, consumable costs, and other variables,” says Hunter.


Next, shop owners should anticipate what types of jobs they plan to tackle with their printers. This could have an impact on the size and cost of the printer selected.


“Sign makers need to assess what kinds of signs they want to offer,” notes Robin Kavanagh, public relations manager, Sawgrass Technology. “This will determine the size of printer and heat press they will need. For example, if they want to concentrate on nameplates, P.O.P. signs and other small signs, a desktop system will likely be enough. The investment would be between $600 and $2,500, depending on whether you need a heat press. I always recommend a 16" x 20" press for these systems, which provide prints up to 13" x 19". If you’re looking to make a high volume of signs, or larger signs, then you’ll need a larger roll-feed printer.”

Sawgrass Technology公关经理Robin Kavanagh指出:“标识制造商需要评估他们想要提供什么样的标识,这将决定他们将需要的打印机的尺寸。例如,如果他们想专注于铭牌、P.O.P. 标识和其他类型的小标识,桌面系统可能就足够了,投资将在600美元至2500美元之间,具体取决于是否需要热压机。我推荐这些系统使用16“x 20”尺寸的打印机,这种打印机可以提供高达13“x 19”尺寸的打印品。如果你想要制作更大规模的标牌,那么你需要一台更大的卷筒式打印机。”

The Substrate


Along with assessing the type of job is choosing the appropriate substrate for the job. For some projects, it is fairly simple to determine which substrate to use; others may present a variety of options.


“It seems that the applications for sublimation are ever expanding beyond the traditional flag application of years past,” says Greg Lamb, CEO, Global Imaging. “The exhibit industry is dominated by fabric as there is no limit to the size and shapes that can be created. Another driver in the exhibit industry is that the lightweight nature of fabric really offers costs savings when it comes to drayage.”

全球影像公司首席执行官Greg Lamb说:“染印升华的应用程序已经超越了过去几年传统的标识应用程序。例如,展览业主要以织物为主,它们可以创造出任何尺寸和形状的标识,并且织物的轻质性确实可以节省成本。”

Hunter agrees that exhibit displays are common choices for dye sublimation printing. She also notes that “Flags, backlit signs, backdrops, table covers, tents—all of these are popular dye-sublimation applications within the sign industry. However, rigid signs, menu boards, flooring, and tables are some great examples of additional products that can also be sublimated.”

Hunter 指出:“标识、背光标志、背景桌面、帐篷,所有这些都是广受欢迎的染料升华应用范围。此外,刚性标牌、菜单板、地板图案这些也在这种应用的范围。”

It’s in the rigid substrate category where recent growth has occurred. Kavanagh points out that “Hard signage applications are often overlooked. Metal panels are now designed to withstand outdoor conditions and UV exposure, which makes hard signage applications more versatile than ever. Metal photo panels easily turn into static menus. Table tops, ceiling tiles and large floor mats can be sublimated into promotional signs. POP signage applications are endless, as are the opportunities to create every sign a customer needs. Directional signs, identification signs, decorative artwork, promotional signs, even name badges—the list goes on and on.”


Ink and Software


Many sign makers are already familiar with RIP software and the processes involved with bringing the design to the substrate. With sublimation, and an emphasis on heat and transfer, the operation is a little different than with traditional digital printing.






“You will always want a heat press that is larger than the maximum dimensions of prints your printer can offer,” says Kavanagh. “One of the advantages of these systems is that they usually have eight-color capabilities. This enables you to use application-specific inks (photographic, fluorescent, etc.) and hit more colors than is possible through CMYK alone.”


Expanding on the ink selection, Hunter explains that ,“While you’ll be using water-based dye-sublimation inks, know that not all inks are alike. Some inks cost less, but may not have high dye-content. If this is the case, you’ll need to use more ink to get the desired color vibrancy.  Roland’s specially formulated Texart SBL3 inks not only have high-dye content, they can be set up in a variety of ink configurations—2X CMYK, CMYKLcLmOrVi, CMYKOrViFyFp—to suit the user’s specific needs. Our dense black dye-sublimation ink has high opacity and provides rich colors and neutral grays.”

Hunter解释道:“虽然你使用的是水性染料升华油墨,但并不是所有的油墨都是相同的。 一些油墨成本较低,可能不具有高染料含量,在这种情况下,需要使用更多墨水才能获得所需的颜色鲜艳度。像Roland公司特殊配方的Texart SBL3油墨不仅具有高染料含量,而且可以设置为多种油墨配置(2X CMYK,CMYKLcLmOrVi,CMYKOrViFyFp),以满足用户的特定需求。而我们致密的黑色染料升华墨水具有高度不透明性,也能提供丰富的色彩和中性灰色。”

Then comes the decision in selecting the software. Kavanagh suggests “A high-quality ink manufacturer will provide all of the software you need to print your designs and get the right colors and quality when sublimated, though RIP software is recommended for mid-format printers, which can add some expense. There are many resellers out there who offer substrates and papers for various applications.”


Hunter points to a couple of software solutions with dye-sublimation jobs. “Two types of software will be needed for dye-sublimation applications—a design software and a RIP software,” she says. “Popular graphics design software includes offerings from Adobe and Corel. Once you have your graphics design, a good RIP software will translate the information accurately to the printer to ensure a high-quality imaging. Roland’s Texart dye-sub printers come bundled with the latest version of ErgoSoft Roland Edition software.”

Hunter指出了一些用于染印升华工作软件的解决方案。染印升华应用需要两种类型的软件 ,包括一种设计软件和一种RIP软件。现在流行的图形设计软件包括来自Adobe和Corel的产品。例如,Roland的Texart染印打印机与最新版本的ErgoSoft Roland Edition软件捆绑在一起,一旦你有了图形设计,RIP软件就能将把信息准确地转换到打印机上,以确保高质量的成像。”

The Finishing


When working with fabrics or soft materials, there is a finishing process that should not be overlooked. “Automation in cutting is an important consideration,” says Lamb. “The fabric printers that we currently represent, produce fabric at speeds of 1,000 to 1,600 square feet per hour. Hand cutting or heat knifing while trying to keep up with those speeds is impossible without dedicating a significant labor pool to that single job. In general, knit fabrics are cut beautifully with a driven rotary tool while woven are typically heat sealed with a laser. As a Zünd partner, our platform offers both solutions while adding the benefits of stress-free fabric feeding to the cutting area which eliminates mistakes in cutting due to potential stretch and mis-registration.”

使用织物或软材料时,有一个不应忽视的整理过程,切割中的自动化步骤是一个重要的考虑因素。 Lamb说:“目前,我们的织物印花机生产织物的速度为每小时1,000至1,600平方英尺,如果没有为这项单一工作投入大量的劳动力,手工切割或热切割就不可能跟上这些速度。 一般来说,针织面料是用一个从动旋转工具精美剪裁的,而织物通常是用激光热封的。作为Zünd的合作伙伴,我们的平台提供了两种解决方案,同时在切割区域增加了无压力织物喂入的好处,消除了潜在拉伸和错位导致的切割错误。”

Hunter agrees that shop owners should probably consider the purchase of a cutter to add to their dye-sublimation operation.


“Some companies start off small, using rotary blades or heat blades to manually cut their fabrics,” she explains. “Heat blades are used primarily with woven fabrics for sealing the edges to prevent frays. Knit fabrics do not fray, so rotary blades work well on those types of materials.  Other materials used for dye-sublimation applications include polyester fabrics, polyester-coated fabrics and polyester-coated rigid substrates. As the business grows, the print service provider should consider investing in a quality flatbed cutter.”


Once the cutting is completed, the job is finished by sewing the edges.


“Almost all of our customers have invested in a synchronized sewing machine from Impulsa,” says Lamb. “It uses a conveyor to transport the fabric to the sewing head at the same speed as the needle is stitching. In addition to this feature, is synchronized feeding of the silicon edging, webbing or Velcro, allowing for better seam quality and faster production.”


Direct vs. Transfer


Even within the niche dye-sublimation printing process there are options to attain the final outcome. The finished dye-sublimation product you see at a tradeshow, on a point-of-purchase display, or elsewhere has either been printed directly or transferred using the appropriate media.


“The dye-sublimation printing process is really no different within the sign industry than any other industry,” says Hunter. “Typically, the transfer sublimation process involves first reverse-printing onto transfer paper with a wide-format dye-sublimation inkjet printer. A heat press is then used to transfer the image from the paper to the substrate. The type of heat press you use—a calender heat press or a flatbed heat press—will depend upon the product you’ll be making (i.e. rigid signage or soft signage).”


The advantages to transferring, according to Garcia, is “typically lower cost equipment; however, you need to buy extra consumables such as transfer paper.”


Direct printing is a completely different process and occurs when “fabric is fed through the printer and the sublimation inks are printed directly onto the fabric,” explains Hunter. “Sign makers should be aware that, regardless of whether transfer or direct dye-sublimation is being used, they will still need to ‘fix’ the inks onto the substrate at the heat press. Traditionally, soft signage that requires heavy saturation, such as flags, are produced using the direct printing method.”


There are certainly benefits and drawbacks to direct print
ing as well. Garcia says there is “Less human handling, hence faster outcome and fewer chances to making mistakes.”


On the other hand, Kavanagh points to the newness of this technology to highlight its limitations.


“Currently, the direct-printing process can only be used with fabrics and fixation takes place in a wide format calendar press,” she says. “The dyes are applied directly to the fabric and penetrate further, which can result in some blurring and lighter coloration.”


Sign makers will likely have their own perceptions and comfort level with these processes. And again, the nature of the job may dictate which method is best suited. For instance, fabric projects are a natural fit for direct printing.


“We believe the most productive method of printing is direct to fabric with an inline calendar," says Lamb. "It offers fast finished productivity and a lower cost of production due to decreased labor and the elimination of transfer paper. As an example, if you consider the methods of transfer versus direct at a speed of 1,000 square feet per hour, the inline system offers finished goods at that print speed.”


“Transfer sublimation,” Kavanagh counters, “offers much more flexibility for sign makers, as they can use small systems and create transfers for many other types of substrates in addition to polyester fabric.”


Today and Tomorrow


Looking ahead, there undoubtedly remains a fit for dye-sublimation in the signage world. Many argue that some of the current applications can still be expanded to include sublimation printing. Point of purchase is one of those areas.


“The retail point of purchase space is seeing wide adoption with the advent of SEG (silicon edge graphics) framing for both backlit and front lit applications,” explains Lamb. “Fabric eliminates many of the issues associated with traditional vinyl applications such as installation, glare and higher freight costs. Consider Apple and H&M stores which are full of fabric. Most airports also now take advantage of fabric in SEG frames for their advertising needs.”


“I think a lot of people do not think of creating murals with sublimation, but this is a great application for the sign maker,” says Kavanagh. “Our trade show booths often consist of large ChromaLuxe panel murals, and many sign makers have found applications for murals with their clients. Another great application is turning tabletops into signs. Unisub offers a few different table top shapes that you can sublimate onto, making them a blank canvas for adding signage to a business or public areas.”


Overall, “The popularity of dye-sublimation for producing signage/displays has grown tremendously over the last few years,” says Hunter, “and we expect to see continued growth in the near future. Sales of Roland’s Texart dye-sublimation printers and SBL3 sublimation inks have also increased with this growing consumer demand. The applications for dye-sub are virtually endless, and they go way beyond textiles.”


Kavanagh agrees, and adds that “The market demand for sublimated signage is growing, as our society becomes more and more oriented to visual messaging. Dye sublimation is a natural fit in the signage market because of its ability to deliver high-resolution ../images, custom graphics and photos.”


Garcia forecasts that “Due to the versatility of sign applications and the luxury feel and look of soft signage signs, there will be continual growth of dye sublimation signage during 2018  and beyond.”
