Why are there bubbles when using uv ink?With the rise of uv ink, many factories have
also decided to start developing ink production technology to keep up with the trend of
the times. However, many people do not know that uv ink will produce a large number of
foam due to various reasons in the production process. The existence of these foam will
not only affect production efficiency, but also make the quality of processed ink fail to
meet the sales standards. The reasons for blistering in uv ink processing are as follows:
Why are there bubbles when using uv ink?The poor pretreatment of the substrate did not
clean the substrate before printing, which made its surface full of dirt or oil stains, resulting
in foam; uv ink contains bubbles. If the ink is improperly mixed, a little bubbles will be mixed
in the ink when adding additives and stirring solvents. If these bubbles cannot burst by themselves,
more foam will appear. If the ink viscosity is low, the possibility of natural defoaming is relatively
large, while the ink with high viscosity cannot naturally defoaming.
Why are there bubbles when using uv ink?For some transparent uv inks that are easy to bubble,
such as common transparent red, blue, and green inks, the amount of organic pigment in
the particles is reduced, so the connecting materials of these inks are easy to bubble. Printing speed
causes blistering printing speed to be too fast or uneven, which is also a major cause of blistering.
