-
Infrared Flash Dryers: These dryers emit infrared emission heat, which is absorbed directly by the ink, causing it to cure quicker. Infrared dryers are often the most vitality-efficient and can be great for most types of inks.
-
Quartz Flash Dryers: These use crystal bulbs to emit heat, drying the ink speedily by straight divergent heat onto the surface. Quartz dryers are often faster but may not be as energy-efficient as infrared radiation dryers.
-
Convection Flash Dryers: These dryers circulate hot air around the print to cure the ink. They tend to be slower but are useful for more ticklish materials that may be prone to from aim heat.

-
Consistent Heat: Ensure the show off drier is distributing heat to avoid hot floater. Some dryers come with a fan or rotating mechanics to ensure unvarying reporting.
2. Flash Cure Between Layers
