The WT-90SK is a manual hot stamping machine tested for foil transfer on glossy cardstock. In the documented comparison, 110°C produced the most complete transfer and the clearest edges among the tested settings of 90°C, 100°C, 110°C, and 130°C. Use that result as a starting reference for the tested material and process, then confirm the setting with your own cardstock, foil, and die before production.
Gloss-coated cardstock can show crisp foil detail, but the surface coating makes a stable transfer dependent on the combination of heat, pressure, dwell time, foil, and die. The WT-90SK is a manual hot stamping press tested on glossy cardstock, with a documented temperature comparison that gives paper converters, packaging studios, and stationery workshops a practical starting point.
In the supplied test, the WT-90SK was evaluated at 90°C, 100°C, 110°C, and 130°C while pressure, stamping time, foil, die, and other test conditions were held constant. 110°C gave the best overall result in that test: the lettering transferred completely, edges remained clear, and adhesion was even. This is a reference result for the tested combination, not a universal setting for every coated stock or foil.
The temperature comparison showed how the transfer changed across the four settings:
| Test temperature | Observed result | Test assessment |
|---|---|---|
| 90°C | Extensive incomplete transfer and unstable adhesion | Not recommended for the tested setup |
| 100°C | Improved, but visible missing foil and broken strokes remained | Not recommended for the tested setup |
| 110°C | Complete lettering, continuous strokes, clear edges, even adhesion | Best result in this test |
| 130°C | Thickened strokes, edge spread, and localized foil bleed or sticking | Too high for the tested setup |
The report also notes that the cardstock showed no obvious yellowing, deformation, or excessive impression at 110°C under the test conditions. Before a production run, make a sample using the exact stock, coating, foil, artwork, die, and backing that will be used in the job.
The documented application is hot foil stamping on glossy cardstock. This makes the WT-90SK relevant to work such as premium cards, invitations, paper labels, and packaging panels when the stock and tooling are compatible. These are prospective use cases, not separate material tests; validate each one with a sample before quoting a production setting.

The best overall result in the supplied comparison was at 110°C. It is a reference for that test’s cardstock, foil, die, pressure, and dwell time, not a guaranteed setting for other materials.
At 130°C, the report describes thicker strokes, edge spread, and localized foil bleed or sticking. This setting was too high for the tested cardstock, foil, and die combination.
Other coated or uncoated papers may respond differently. Confirm foil compatibility and run a sample with the intended stock, die, pressure, and dwell time before production.
The machine was evaluated in a controlled test, but the supplied report does not provide a production rate or a validated run-length specification. Send the stock, artwork size, expected quantity, and sample requirements for a machine and process recommendation.
