4. 3. Ink Film Splitting Acoustics in Offset Printing

   Författare :Joakim Voltaire; Per Claesson; Douglas Bousfield; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : This thesis claims a relationship between the film splitting sound emission from the printing press nip and the dynamic interaction occurring there between ink, fountain solution and substrate in offset lithography. The film splitting sound derives from the cavitation formed by the pressure drop in the second half of the print nip flow passage. LÄS MER
