Abstract

Non-image area piling on blanket is considered as a process property of offset printing, which influence on print quality and press runnability. There is not a single reason for piling - it is always a combination of press settings and all the materials used in printing. In this study the role of the printing plates and fountain solution purity on piling build-up was clarified. It was found that piling formation is sensitive to plate characteristics; different plates produced different kind and amount of piling on blanket surface. Ink spread to the non-image area of the plate as spots or tails and ended up on the non-image area of the blanket. The main reason for the non-image area piling was found to be the poor emulsion stability on the plate. The fountain solution itself did not cause non-image area piling on the blanket but it affected the mechanism of piling by interacting with the ink. With fresh fountain solution, the ink spread mainly as tails from the back edges of the dots, while with used fountain solution mostly ink spots were noted on the plate non-image area.
