Method for moistening print carrier surface in offset printing machine, involves distributing vapor stream along preset direction such that vapor is fed uniformly to print carrier surface through openings in vapor deposition unit

摘要

#CMT# #/CMT# The method involves printing color ink at a print substrate (2) onto a carrier material portion (5). A moisture film (4) is formed on a print carrier surface (3) through a vapor deposition unit (6). The vapor stream (7) is distributed within the vapor deposition unit along the print carrier width direction such that the vapor is fed uniformly to the print carrier surface through the openings in the vapor deposition unit. #CMT# : #/CMT# An independent claim is included for device for moistening print carrier surface with moisture film. #CMT#USE : #/CMT# Method for moistening print carrier surface in offset printing machine. #CMT#ADVANTAGE : #/CMT# The moistening process of the print carrier surface in the offset printing machine can be performed efficiently. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic views illustrating the process for moistening print carrier surface. 2 : Print substrate 3 : Print carrier surface 4 : Moisture film 5 : Carrier material portion 6 : Vapor deposition unit 7 : Vapor stream.
