A coating device for coating a peripheral surface of a sleeve body with a coating formulation includes a vertical support column for supporting a sleeve body in a vertical position coaxial with a coating axis, a carriage slideable along the vertical support column, and an annular coating stage attached to the carriage and moveable therewith for containing the coating formulation and for coating a layer of the coating formulation onto the peripheral surface of the sleeve body during a sliding movement of the carriage along the vertical support column. The coating device includes an irradiation stage that is arranged to be moveable with the annular coating stage and to provide radiation to at least partially cure the layer of coating formulation onto the peripheral surface so as to prevent flow off of the coating formulation.
摘要:
One or more pixel images are stored in a programmable computer. A lenticular sheet having a plurality of lenticules is placed in an inkjet printer having a printhead and a light sensor. The light sensor scans across the lenticular sheet and generates a scan data. A lenticular data is calculated based on the scan data, the lenticular data representing the lenticule spacing or frequency. At least a portion of the pixel images are formatted with a pixel spacing based on the lenticular data and printed. The formatting aligns the pixels with the lenticules.
摘要:
A lithographic printing plate that works according to the silver salt diffusion transfer reversal process is disclosed. The lithographic properties of said plate can be improved by incorporating a hydrophilic amphoteric block copolymer, comprising a non-ionic block of acrylic units with pendant nitrile groups and an acrylamid(in)e block which comprises units with pendant basic and acidic groups. The hydrophilic amphoteric block copolymer is preferentially present in the image receiving layer of the lithographic printing plate. In an alternative embodiment, said block copolymer may be present in a treating solution used for processing said plate or applied onto said plate while printing. The hydrophilicity of the printing plate's surface is improved without deteriorating the ink-acceptance in the printing areas.
