What are the common problems about uv ink printing?Uv ink printing is
very different from the traditional ink, if the traditional process is used to
operate, it is easy to lead to a series of problems, such as: insufficient ink
adhesion, serious ink emulsification, ink dripping ink and ink pulling
phenomenon, ink curing is not completely dry and other phenomena.
What are the common problems about uv ink printing?The adhesion of
ink is not enough. When the permeability of the substrate used when the ink
is curing is relatively poor, it is easy to reduce the adsorption force of ink.
After using the curing of uv curing machine, the adhesion of ink is very poor,
and the ink printing quality is low. At this time, in order to improve the
adhesion of the ink, we need to conduct special treatment to the surface of
the substrate, which can effectively and easily improve the adhesion of the ink
and the substrate surface. Ink emulsification is serious in uv printing, sometimes
found that the edge of the printing network some hair, and the text is not clear,
this reason may be caused by uneven ink and water, causing ink emulsification
phenomenon. After ink emulsification, it is easy to accumulate or remain on the
layout, thus causing unclear text. At this time, it is necessary to reconfigure
the plate liquid printing to avoid the emulsification phenomenon of uv ink.

What are the common problems about uv ink printing?Ink drop ink and ink
pull phenomenon uv ink through a long time of printing equipment operation,
easy to reduce the adhesion of ink, strong fluidity, thus leading to uv ink drop ink
and ink pull phenomenon. When the ink emulsification is serious, the water in
the uv ink will affect the passing rate of the ultraviolet light source of the uv curing
machine, reduce the conjunctival strength of the uvink, although the ink has been
cured, but there is a small amount of water in the ink, it is easy to wipe the ink layer,
the occurrence of ink drawing.4. Ink curing is not completely dry In uv ink printing,
in order to improve the brightness of the printing color, it will increase the thickness of
the ink ink layer, which will improve the difficulty of uv ink curing. In order to match
the printing speed and the uv ink drying, it is necessary to adjust the irradiation time of
the uv curing machine, slow the printing speed, prolong the light time of the uv ink can
thoroughly dry, complete the curing requirements; or can improve the power of the uv
curing machine, increase the light intensity of the uv light source, but also can achieve
the effect of fast curing uv ink.
