Why is the printng dot expanding?

Dot expansion, mainly in the version of the dot, can not be faithfully reproduced, the result of the dot deformation or connected, insufficient contrast, affecting the quality of printed products.


This phenomenon is mostly due to improper ink blending, ink too thin too soft, insufficient concentration, ink blending should be added appropriate amount of debonding, not less ink blending, or use a higher concentration of ink, reduce the amount of ink, this phenomenon can be overcome, followed by printing machine ink roll hardness is not suitable, roller pressure, blanket loose, roller arrangement is also an important cause of this problem, also due to inspection adjustment.
