Sublimation not transferring is one of the most frustrating problems you’ll run into as a crafter. You peel back your transfer paper expecting a vibrant design and instead you see… nothing. Or worse, a faded ghost of what should have been a beautiful print. The good news? There’s almost always a fix!

So many crafters describe the exact same frustration – doing everything “right” but the design just won’t transfer. Whether your sublimation transfer is not working at all, or the image is not showing up the way it should, there’s almost always a clear reason. This guide is meant to save you from guessing, wasting blanks, and changing five settings at once.

Below you’ll find the 9 most common reasons your sublimation is not transferring, plus substrate-specific fixes for mugs, shirts, and tumblers, and a settings cheat sheet you can bookmark.

Quick Diagnostic: What Does Your Failed Transfer Look Like?

Before diving into the 9 causes, match what you see on your blank with the row below. The symptom tells you which cause is most likely.

Symptom	Most Likely Cause	Quick Fix
Faded but visible	Under-temperature, under-time, or moisture	Add 10°F or 15 seconds, pre-press blank
Completely blank (no transfer)	Wrong ink, wrong paper side, or wrong substrate	Verify sublimation ink, check coated side, confirm polymer-coated blank
Ghost / double image	Transfer paper shifted during press	Tape more securely, lift press straight up
White spots in design	Moisture or pressure imbalance	Pre-press to remove moisture, redistribute pressure
Yellow/dull stain only	Not sublimation ink (regular inkjet)	Switch to verified sublimation ink
Bleeding / blurry edges	Over-temperature or over-time	Reduce by 10°F or 15 seconds
Paper stuck to blank	Paper or pressure issue	See paper stuck to tumbler fix
Colors wrong (greens look blue)	ICC profile mismatch	See ICC profile setup guide
Print looks good on paper but does not transfer	Wrong substrate, wrong ink, or protective film still on blank	Confirm sublimation coating, ink type, and film removal

Quick Wins: 5 Fixes to Try First (Under 5 Minutes)

Before deep troubleshooting, run through this fast list. These are the fastest checks to run before you change your whole setup.

• Pre-press the blank for 5-10 seconds to remove moisture
• Check paper orientation – print side faces the blank, never the heat plate
• Verify your ink is sublimation ink with a test smear on polyester scrap
• Tape the transfer paper with heat-resistant tape so it cannot shift
• Add 10°F or 15 seconds to your current settings and re-press a fresh test blank

Why Is My Sublimation Not Transferring? 9 Common Causes

When sublimation is not transferring, it’s usually one of these nine issues. Start with the first few checks before changing your entire setup.

1. Wrong Temperature or Uneven Heat

This is one of the most common reasons for sublimation transfer problems. Sublimation ink needs heat to turn into gas and bond with the polyester fibers – and it needs the right amount of heat.

Your heat press may not be reaching the right temperature, or the display may be inaccurate. Many blanks fall in the 375-400°F range, but exact settings vary by substrate and supplier – always follow the blank manufacturer’s recommendations first. Use an infrared thermometer to verify the actual temperature, since displays can be off by 10-20 degrees. Also make sure your press is fully preheated before you start, which takes a good 10-15 minutes. Even if the displayed temperature is correct, your press may have cold spots or uneven heat across the platen.

My tip: Always verify your press temperature with an infrared gun. Your press might display 400°F but actually run at 385°F – and that 15-degree difference matters!

2. Wrong Substrate (Not Enough Polyester)

Sublimation ink only bonds with polyester. If your blank doesn’t have enough polyester content, the ink has nothing to grab onto.

Sublimation works best on high-polyester fabrics, with 100% polyester giving the most vibrant results. For hard goods like mugs and tumblers, they need a special polyester coating to accept the ink. If your sublimation is not sticking to a blank that looks right, check the product listing – some “sublimation ready” blanks have poor coatings. Always check the tag or product description before buying, and don’t try to sublimate on regular cotton. You’d need a special poly-spray coating for cotton, but honestly the results are never as good. For the most reliable results, stick with high-polyester blanks.

3. Not Enough Time

Even with the right temperature, the ink needs time to fully convert to gas and penetrate the substrate. If you’re pressing too briefly, the transfer will be incomplete or faded.

Many flat sublimation blanks fall around 45-60 seconds, while mugs are often pressed around 180 seconds (3 minutes), though mug coatings and presses vary. Adjust in small increments and test one blank first, since both under-pressing and over-pressing can cause problems. If your transfer looks faded or washed out, try increasing time in 15-second increments until you get vibrant colors.

4. Not Enough Pressure

Pressure keeps the transfer paper in tight contact with the substrate. Without enough pressure, the ink can’t transfer evenly and you’ll get patchy or incomplete results.

For flat items, use medium to firm pressure – you should need some effort to close the press. For mugs and tumblers, make sure the wrap is tight with absolutely no gaps between the paper and the surface. A pressing pillow under shirts can help even out pressure, especially around seams and zippers to ensure even pressure across the entire design, especially around seams and zippers.

5. Moisture in Your Substrate

This one catches a lot of people off guard. Moisture trapped in your blank interferes with the sublimation process and causes faded prints, blurry images, or random spotty areas where the ink didn’t transfer.

The fix is simple: pre-press your blanks for 5-10 seconds before sublimating. This drives out any trapped moisture. Also store your blanks in a dry place away from humidity, and use butcher paper when pre-pressing to absorb the moisture.

My tip: Pre-press most blanks for a few seconds, even items straight out of the package. It helps remove moisture and prevents a lot of common transfer problems.

6. Printing on the Wrong Side of the Paper

Sublimation paper has a coated side that accepts the ink. Print on the wrong side and your sublimation won’t transfer no matter what settings you use.

The coated side is usually brighter white and slightly tacky to the touch, while the uncoated side looks more yellow or grey and feels matte. Most printers load with the coated side facing down. My tip: mark one side of your paper stack with a small dot so you always load it correctly – it’ll save you from this annoying mistake.

7. Clogged Print Heads

If your printer’s nozzles are clogged, the ink won’t lay down properly on the paper – and if it’s not on the paper right, it can’t transfer to your blank.

Run a nozzle check pattern from your printer settings. If you see gaps or missing lines, run 1-2 head cleaning cycles. The best prevention is printing something at least once a week to keep the ink flowing – printers that sit idle for days or weeks are the ones that develop clogs. Print a small test pattern every few days, even if you don’t need to print anything real. It uses a tiny bit of ink but saves you from clog headaches!

8. Transfer Paper Shifted (Sublimation Ghosting)

Sublimation ghosting is when your paper moves even slightly during pressing and you get a blurry double image – a shadow of your design offset from the main print. This is so frustrating because the design was perfect, you just moved the paper a tiny bit.

Use heat-resistant tape to secure paper to all hard substrates, and on fabric, some crafters use a very light, heat-safe adhesive spray to reduce shifting, but test carefully to avoid residue. When you open your press, lift it straight up – never slide or drag. Follow the paper and blank recommendations for peel timing – some projects work better peeled warm, while others are best left to cool briefly. Always tape everything, even items you think won’t shift. Heat tape costs pennies per use and saves entire projects.

9. You Forgot to Mirror Your Image

This one sounds too simple, but it catches even experienced crafters off guard. If your design has text or a specific orientation and you didn’t flip it before printing, the transfer will come out reversed on your blank. Your sublimation might technically “transfer” just fine – but the result is unusable.

Always enable Mirror or Flip Horizontal in your print settings before every single print. Some printer drivers have this setting buried in “Advanced” options. My tip: make it part of your pre-print routine – check mirror, check paper side, check quality setting. Every time, no exceptions.

Sublimation Not Transferring to Specific Substrates

Sometimes the issue is specific to what you’re sublimating onto. If your sublimation is not sticking to one particular type of blank but works fine on others, the problem is almost certainly substrate-related. Here are the most common substrate-specific problems.

Sublimation Not Transferring to Mugs

Sublimation not transferring to mugs is usually one of three things. First, make sure your mug is actually sublimation-coated – regular ceramic mugs from the dollar store won’t work no matter what you do. Sublimation mugs have a special polymer coating that accepts the ink. Second, many ceramic mugs are pressed around 355-400°F for about 180 seconds, but exact settings vary by mug coating and press – always check the supplier’s recommendation first. Third, check your wrap tightness – if there’s any gap between the paper and the mug surface, that area won’t transfer. Use heat tape at the top and bottom edges, plus one strip along the seam to keep everything tight.

Sublimation Not Transferring to Shirts

When your sublimation isn’t transferring to shirts, the polyester content is almost always the issue. Sublimation works best on high-polyester fabrics, with 100% polyester giving the most vibrant results. Lower blends may transfer, but colors will look noticeably more faded. Also make sure you’re using a pressing pillow inside the shirt to even out the pressure, especially around seams, buttons, and zippers. And always pre-press the shirt for 5 seconds first to remove moisture and wrinkles – this alone fixes most fabric transfer problems.

Sublimation Not Transferring to Tumblers

Tumblers can be tricky because the curved surface makes even contact harder to achieve. If your sublimation isn’t transferring to tumblers, check that your shrink wrap is tight enough (or your tumbler press is properly adjusted). Any air gap between the paper and the surface will show up as an untransferred area. For the shrink wrap + convection oven method, make sure your oven is actually reaching 385°F – use an oven thermometer to verify, since home ovens can be wildly inaccurate. Depending on your oven setup, rotating halfway through can help improve evenness.

Sublimation Not Transferring to Hats or Caps

The most common cap problem is not enough polyester in the front patch combined with uneven pressure on the curved surface. Use sublimation-ready foam-front caps, a dedicated hat press if possible, and confirm even pressure across the print area before pressing.

• Use sublimation-ready foam-front caps (polyester or polyester-coated patch)
• A hat press gives more even pressure than a flat press
• Medium pressure works better than firm on most cap fronts
• Secure the transfer with heat tape so it cannot shift on the curve

Sublimation Not Transferring to Glass

Glass blanks need the right coating and gentler pressure than other hard blanks. The most common failure modes are wrong coating, too much pressure, or pulling the transfer before the glass has cooled enough.

• Confirm the glass is sublimation-coated, not regular glass
• Follow the glass blank supplier settings rather than a generic recipe
• Use light pressure and test one blank first to avoid cracking
• Allow the glass to cool partially before peeling, per blank instructions

Sublimation Not Transferring to Coasters

Coasters fail for the same reasons as other hard blanks: wrong coating, protective film left on, uneven pressure, or too little heat and time. Ceramic coasters usually need light-medium pressure, while MDF or hardboard coasters may need the protective film removed first. Always confirm which side is sublimation-coated before pressing.

• Check that the coaster is sublimation-coated, not a generic coaster
• Remove any protective film from MDF or hardboard coasters before pressing
• Use light-medium pressure for ceramic, slightly firmer for MDF
• Place coaster on a heat-safe surface and avoid stacking pressed coasters while hot

Sublimation Not Transferring to Hard Blanks (Metal, MDF, Acrylic)

Hard blanks behave differently from fabric or ceramic. They need higher pressure (firm-medium) and longer time, but the temperature is similar to other substrates. The most common failure here is forgetting to peel the protective film off the blank before pressing – the film looks like the substrate but blocks the dye completely.

• Remove the protective film from metal and MDF before pressing. For acrylic, follow the blank supplier instructions carefully – some sublimation acrylic blanks have protective layers that must be removed in a specific order
• Use firm pressure on flat hard blanks (more than fabric, less than mugs)
• Press time 60-90 seconds for most hard blanks at 400°F
• Cover with butcher paper or Teflon sheet to protect from ink bleed

Sublimation Settings Cheat Sheet

Here are the recommended settings for the most common sublimation blanks. These are common starting points – always follow your blank supplier’s settings first, and adjust based on your specific press and blanks.

Substrate	Temperature	Time	Pressure
Polyester Shirts	385°F	45-60 sec	Medium
Ceramic Mugs	355-400°F	180 sec (3 min)	Firm wrap
Tumblers (press)	360-385°F	40-90 sec per zone	Firm wrap
Tumblers (oven)	385°F	6–7 min	Shrink wrap
Mouse Pads	400°F	50-60 sec	Medium
Coasters (Ceramic)	400°F	60 sec	Light-Medium
Metal Signs	400°F	60-75 sec	Medium
Puzzles	385°F	45-60 sec	Light
Glass	365-400°F	120-180 sec	Light – supplier settings first
Ornaments	400°F	60-90 sec	Light-Medium
Phone Cases	385-400°F	45-90 sec	Light (depending on insert)

Remember: These are guidelines. Always do a test press with new blanks before committing to a full project!

Pre-Press Checklist for Better Sublimation Transfers

Before you press, run through this quick checklist. Print this out and keep it next to your press – it catches problems before they ruin a blank!

Before Printing:

• Print a nozzle check – are all colors showing?
• Confirm paper is loaded coated side down
• Verify your image is mirrored or flipped
• Set print quality to “High” or “Best”

Before Pressing:

• Verify your heat press is fully preheated (not just “ready” on the dial)
• Check actual press temperature with an infrared gun
• Pre-press the blank for 5-10 seconds to remove moisture
• Lint-roll fabric or wipe down hard blanks before placing the transfer
• Secure the transfer paper with heat-resistant tape so it cannot shift
• Set your timer for the correct duration for your specific substrate

After Pressing:

• Lift the press straight up without sliding
• Peel the paper according to your paper or blank recommendations
• Check for missing areas, faded spots, ghosting, and paper residue before repeating the same settings

Sawgrass vs Epson: Printer-Specific Troubleshooting

The two most common sublimation printer ecosystems have different failure modes. If you know which one you own, start with the brand-specific checks below.

If you own a Sawgrass (SG500, SG1000, Virtuoso):

• Check that the printer is printing through Sawgrass Print Utility and that your job/settings are coming from MySawgrass or your design software, not a generic system driver
• Run a print head clean from the printer panel, then power cycle the printer
• Check the cartridge use-by/expiration date printed on the cartridge. Old or expired cartridges can contribute to weak color, clogs, or inconsistent transfer
• Make sure the printer ran a maintenance cycle in the last 7 days – idle printers clog faster

If you own an Epson EcoTank (ET-2800, ET-2803, ET-2850, ET-4800, etc.):

• Confirm you converted the printer correctly and used 100% third-party sublimation ink
• Print an ICC profile test page – converted Epsons often need a custom ICC profile
• Run multiple nozzle checks – converted printers can clog more easily during idle periods
• If the printer was idle for over a week, start with a nozzle check and 1-2 standard head cleanings if needed. Use power cleaning only as a last resort because it uses a lot of ink

For deeper printer maintenance, see the 5-tier unclog system.

Advanced Checks If Sublimation Still Is Not Transferring

If you’ve checked everything above and your sublimation is still not transferring properly, here are a few more things to investigate.

Sublimation not bright or looking washed out? Try increasing temperature by 5-10°F and adding 15 more seconds of press time. Also double-check that you’re using actual sublimation ink and not regular inkjet ink – this is more common than you’d think, especially with budget printer setups. If your sublimation is faded consistently, moisture is likely the culprit – pre-press every blank!

Getting a yellow tint or no transfer at all? Your ink might not be sublimation ink. Here’s a quick test: smear a little ink on sublimation paper and press it onto a polyester scrap. If nothing transfers or you just get a yellow stain, it’s not sublimation ink.

Colors look wrong (greens are blue, etc.)? You may need an ICC color profile for your specific ink brand. Check out my guide on fixing green printing blue for a detailed walkthrough.

Only some colors transfer? One or more print head nozzles may be clogged. Run multiple cleaning cycles and check your ink levels – you might simply be out of one color.

Wrapping Up

When your sublimation is not transferring, it’s almost always one of these nine issues: wrong temperature, wrong substrate, not enough time, not enough pressure, moisture, wrong paper side, clogged heads, paper shift, or a forgotten mirror setting.

The good news? Every single one of these problems has a fix. Start by checking temperature accuracy and heat consistency first, since those are among the most common causes of poor transfers. Then work through the rest of the checklist.

Don’t get discouraged if your first few attempts don’t work out. Sublimation has a learning curve, but once you dial in your settings for your specific equipment, you’ll get much more consistent results.
