Abstract:
The most common printing technique today is lithography. The difference between printing and nonprinting areas on a printing plate is accomplished by opposite physical and chemical properties of those areas. The printing areas are made of photoactive layer that attracts oil and chemical substances with oil solvent – printing inks. The nonprinting areas are made of aluminium oxide which attracts water based substances – the fountain solution. The aim of this paper was to determine how some parameters in plate making process influence on surface properties of nonprinting areas. The investigated parameters were developing time and exposure time. Contact angle between sample of fountain solution and nonprinting areas on a printing plate was measured to observe surface properties of the nonprinting areas. One can see that both parameters have significant influence on surface characteristics of the nonprinting areas.
