Essential Supplies Checklist for Glass Can Sublimation
Before you start printing and pressing, make sure your workspace is prepped with the right tools. Having dedicated sublimation equipment is key to getting vibrant, long-lasting results.
- 16oz sublimation-ready glass can cups (must have a poly-coating)
- Sublimation printer loaded with dedicated sublimation ink
- High-quality sublimation paper
- Heat-resistant tape and protective heat gloves
- Tumbler heat press or a dedicated convection oven with shrink wrap sleeves
- Digital downloads, such as our trendy coffee PNG files
Comparing Clear vs. Frosted Glass Cans
When shopping for blank cups, you will usually choose between clear and frosted glass. Your choice of glass directly impacts how your final PNG design will look, as sublimation ink is semi-transparent.
| Glass Type | Best PNG Design Style | Typical Press Settings | Visual Result |
|---|---|---|---|
| Clear Glass | Dark, bold colors (black, deep red, navy) | 360°F for 120 seconds (turn halfway) | Transparent, stained-glass effect. White areas in the design will show as clear glass. |
| Frosted Glass | Lighter colors, pastels, detailed graphics | 360°F for 120 seconds (turn halfway) | Vibrant, opaque, matte finish. Colors pop much brighter than on clear glass. |

Step-by-Step: How to Sublimate a Glass Can Cup
Once your supplies are ready, the pressing process is straightforward. Follow these steps to achieve a flawless, seamless transfer on your drinkware.
- Measure and Size Your PNG File:Standard 16oz cans usually require a wrap sized around 9.4" x 4.3", but always measure your specific blanks with a flexible measuring tape. Size your sunshine iced coffee design in your preferred editing software.
- Print and Trim the Transfer:Print your design mirrored. Once printed, trim the top and bottom edges of the sublimation paper closely to avoid harsh lines or ink bleeding where you don't want it.
- Tape the Design Tightly:Wrap the printed paper tightly around the glass cup. Secure the seam firmly with heat-resistant tape, ensuring there are no air pockets. Tape around the top and bottom rims to prevent ghosting.
- Press the Glass:If using a tumbler press, set it to 360°F. Press the glass for 60 seconds, rotate it 180 degrees, and press for another 60 seconds. (Always verify the exact time and temperature guidelines provided by your blank manufacturer).
- Cool and Reveal:Put on your heat gloves to remove the hot glass from the press. Let it cool on a heat-safe mat for a minute or two before peeling the tape and paper away to reveal your finished cup.
4 Common Mistakes to Avoid
Even experienced crafters run into issues when sublimating glass. Keep these common pitfalls in mind to reduce wasted materials.
- Using non-sublimation glass:Regular glass from a dollar store will not hold sublimation ink. You must use blanks specifically coated for the sublimation process.
- Loose taping:If the paper isn't completely flush against the glass, the ink will escape during heating, resulting in blurry edges known as ghosting.
- Forgetting to mirror the image:Always mirror your sublimation craft designs before printing so any text reads correctly on the final product.
- Using white in your design on clear glass:Sublimation printers do not print white ink. Any white areas in your PNG file will simply show up as the clear glass underneath. If your design relies heavily on white details, opt for frosted glass instead.
