摘要： To permit elimination of dampening rollers or an entire dampener in a lithographic, preferably offset printing machine, the printing form is formed as a cylindrical sleeve or jacket (3) fitted over a core (2), in which the cylindrical sleeve or jacket is formed with a plurality of interconnected pores (5), essentially uniformly distributed over the surface (4) and forming, within the sleeve or jacket, a connected pore fluid transfer network. Dampening fluid is then applied to the interior of the sleeve or jacket, for example from a chamber (6) between the cylindrical core (2) and the inner surface of the sleeve or jacket. The outer surface (4) can be imaged with oleophilic substances, for example by a thermal transfer process. To remove the images, for re-use of the printing form without removal from a printing machine, hot gases for example steam can be applied to the interior of the sleeve or jacket, so that the oleophilic substances at the outside will loosen for easy removal, or spall off.

摘要： An additive for lithographic printing fountain solutions to replace isopropyl or ethyl alcohols is defined that comprises a volatile material that lowers the surface tension of the fountain solution. The volatility of the material with respect to water causes an aggressive spreading that is associated with performance similar to the alcohols currently in use.

摘要： A dampening water composition for lithographic printing which comprises 0.1 to 5% by weight of at least one member selected from the group consisting of monoalcohols or diols of alkanes or alkenes having 5 to 11 carbon atoms, to which 1 to 10 moles of ethylene oxide and/or propylene oxide are added. The dampening water composition is not toxic, has not a possiblity of causing a fire and pollution of working atmosphere and, therefore, the use of a local exhaust installation is not necessary. Moreover, it is excellent in characteristics as dampening water such that it does not cause contamination of metering roll, has good bleeding properties, emulsifying properties and stability in continuous processing as well as low foaming properties. Thus, the composition makes printing operation quite stable.
