In terms of ink and varnish curing, most manufacturers use mercury lamps for curing due to procurement costs. Although mercury lamps have the advantages of low purchase cost and broad spectrum, after a period of use, a large number of white attachments are easy to accumulate on the surface of the lamp tube and cannot be removed, which will reduce the light emitting efficiency of the lamp tube and affect the ink curing effect.

So, if you use a UVLED curing machine for ink curing, what is the effect? The composition of uv ink is different from that of traditional ink. Traditional solvent-based inks require heat to participate in the curing process to volatilize the solvent components in the ink to accelerate curing. However, if the uv ink is cured with a high-power mercury lamp, the problems mentioned above will occur. At this time, we need to choose a low-heat UV light source to avoid ink volatilization at high temperatures.
