Ordinary dye sublimation is not a direct print onto cotton. Epson describes the transfer as sublimation ink printed on special paper, then moved by heat and pressure into polyester fabric or a polymer-coated surface. The cotton examples in the reviewed sources add a separate material layer or transfer film, which changes the equipment, supplies, and instructions.
The useful choice is not “which sublimation setting works on cotton?” It is “which documented transfer path fits this exact shirt and the equipment I can support?”

| How cotton is addressed | The Epson process overview names polyester fabrics or polymer-coated surfaces; it does not describe direct sublimation on untreated cotton. | Epson's DTF Film Printing Guide includes a cotton T-shirt post-processing path for a DTF-capable printer. | Siser describes printing sublimation ink on EasySubli HTV, then cutting, weeding, and applying it to a listed compatible fabric. |
| Printer and print surface | Sublimation printer, sublimation ink, and special transfer paper; the destination material must fit the documented dye-sub scope. | A printer model that supports film printing, DTF film, and white ink mode in Epson's documented workflow. | Siser says EasySubli inks are available for the Sawgrass SG500 and SG1000; it does not establish other printer-and-ink combinations. |
| Work after printing | Place the printed transfer against the exact compatible blank and follow its source-matched press instructions. | Apply and heat adhesive powder, transfer the film with a press, peel it, then heat-fix the transferred ink. | Cut and weed the printed HTV, cover it, and press using the current product instructions. |
| Settings scope | The process overview does not give a cotton recipe because its stated fabric scope is polyester. | Epson says DTF conditions vary with film, powder, fixing equipment, fabric, and ink amount; use those material instructions. | Siser says to preheat the garment for 2–3 seconds, then press at 310°F/155°C for 15 seconds with medium pressure. EasyPress users add about 30 degrees; the page does not specify the scale in that clause. |
Keep direct sublimation in its documented material scope
For direct sublimation, the transfer carries dye into polyester fabric or a polymer-coated surface. It does not turn ordinary cotton into a sublimation blank. The printer guide and ink guide explain the exact printer systems in this catalog; the blank compatibility guide shows how to verify one garment's fiber and process listing.
As a contrasting listing example, JPPlus describes its selected Vapor Apparel Ash Heather 4X tee as 100% spun polyester and suitable for sublimation. The listing gives garment measurements, not a print rectangle. That evidence applies to that exact variant and does not establish a cotton process or a universal shirt-size rule.
Choose a documented transfer route for cotton
DTF film
Epson's DTF guide describes printing film on a model that supports DTF, applying and heating adhesive powder, transferring the image to media with a press, peeling the film, then heat-fixing the ink. For its cotton T-shirt example, the guide lists 170°C (338°F) for 25 seconds at 4.2 N/cm² for the transfer, followed by a separate 5-second ink-fixing press at the same listed temperature and pressure. These are Epson guide values for its DTF workflow; its notes say conditions vary by film, powder, press, fabric, and ink, and instruct users to test pressure. The PDF is not a cotton recipe for an Epson sublimation printer such as the F170 or F570. It lists extra equipment and protective items for powder handling.
Do not copy a DTF time or temperature into a direct sublimation project. The ink mode, printer, film, powder, press, shirt, and finishing steps form one path. See the DTF comparison guide for the full process contrast.
EasySubli printed HTV
Siser describes EasySubli as matte heat-transfer vinyl that accepts sublimation ink. Its current page lists 100% cotton, 100% polyester, and cotton/polyester fabrics as compatible; its colored-polyester claim excludes garments that have already been sublimated. EasySubli is a carrier-based workflow, not ordinary sublimation paper pressed directly onto untreated cotton.
Siser says EasySubli inks are available for the Sawgrass SG500 and SG1000 and can also be used for standard dye-sublimation projects. This supports that named ink/model pairing, not every printer or ink combination. The application instructions call for cutting and weeding the printed HTV, covering it with a heat-transfer cover sheet or multipurpose paper, preheating the garment for 2–3 seconds, and pressing at 310°F/155°C for 15 seconds with medium pressure. Siser says EasyPress users should add about 30 degrees, without specifying the scale in that adjustment clause, and that the EasySubli mask is peeled hot. Check the current instructions for the exact EasyPress setting. These are general product instructions, not a setting for every blank or a Cricut-specific recipe.
Siser recommends waiting 24 hours before the first wash, machine-washing cold with mild detergent, drying on a normal dryer setting, avoiding dry cleaning, and avoiding liquid fabric softener. Follow the current package and garment care instructions for the exact materials you use.
Treat VersiFlex as a separate product system
Sawgrass describes VersiFlex as a print-and-press workflow for natural fibers, distinct from SubliJet UHD conventional sublimation. It warns against mixing the two ink systems. The name “sublimation” on a printer or on a supply page is not enough to make its paper and ink interchangeable with direct polyester sublimation or DTF film.
Before buying, match the exact printer model and region, ink, transfer medium, cutter or powder supplies, blank, and press instructions. If a source describes only a discontinued printer or does not name a current exact model, record current compatibility as unknown rather than assuming the successor works the same way.
Compare the full job cost
Price a complete list for the exact route: printer and ink, transfer paper or film, powder or special HTV and mask, cutter where required, press, shirt, protective supplies, test material, and expected waste. The sources reviewed do not give current like-for-like per-shirt prices or a quality ranking across these processes. Use the project cost worksheet with current quotes and quantities you choose.
For sizing, use the dimensions of the print surface and transfer media as separate constraints. The T-shirt design-size guide explains how to measure a chosen decoration area; the printable-area guide keeps sheet size, printer bounds, and blank area distinct. The design-size helper calculates from the dimensions you enter but does not determine a shirt's print area.
