Frequently Asked Questions

Why are my sublimation prints coming out faded?

Faded prints are almost always caused by pressing temperature too low, pressing time too short, or a press that hasn't fully preheated. Many mug presses run 10–20°F cooler than the dial shows — always verify with a separate infrared thermometer. Allow 5–10 minutes for the press to fully preheat before placing a mug and use manufacturer-recommended sublimation ink. Generic third-party inks produce significantly duller color output.

What causes ghosting on sublimation mugs?

Ghosting is caused by the transfer paper shifting during or immediately after pressing. Use 10mm or 20mm width heat-resistant tape on all four edges of the paper — wider tape holds the curved mug surface more securely than narrow tape. Always peel the paper immediately while the mug is still hot. Letting the paper cool on the mug causes condensation to form between the paper and surface which creates a blurred second image.

Why do I have track marks or roller marks on my sublimation print?

Roller marks — sometimes called pizza wheel marks — are caused by the printer's rubber feed wheels rolling over wet ink before it has dried. This is a paper issue not a printer issue. Switch to sublimation paper with an instant-dry or quick-dry coating which locks ink on the surface immediately after printing. Also try disabling bi-directional printing and enabling quiet mode in your printer settings to slow the print speed slightly.

Why are my sublimation mug colors wrong or mismatched?

Incorrect ICC color profiles are the most common cause. Calibrate your printer with the correct ICC profile for sublimation and convert all colors to CMYK before printing — sublimation cannot accurately reproduce RGB neons or deeply saturated colors. Also check your paper — standard fabric sublimation paper does not perform the same as high-release paper designed for hard substrates like mugs.

Why is my sublimation print cracking?

Cracking is caused by thermal shock — cooling the mug too quickly after pressing. Never run a hot mug under cold water or place it directly on a cold surface. Instead place the mug in front of a fan immediately after peeling the paper — this cools evenly without thermal shock. Glass and frosted glass mugs are especially vulnerable to rapid temperature change.

Do I need a dedicated sublimation printer or can I use a converted Epson?

Both work but produce different results. A Sawgrass SG500 or SG1000 using SubliJet UHD ink produces significantly more vibrant and accurate color than a converted Epson EcoTank — particularly in reds, blues, and skin tones. Roller marks are also more common with converted Epson printers. The per-print ink cost on a Sawgrass is approximately $0.01–$0.02 per print and it comes with a 2-year manufacturer warranty. A converted Epson has a lower entry cost but requires more maintenance and produces less saturated color on hard substrates like mugs.
