Fine Corrugated Board directly Offset printing First, consider the fine uneven surface of corrugated board problem. Different from ordinary cardboard printing, fine printing of corrugated board must be in by the corrugated peaks and troughs caused by the uneven surface on. Offset on uneven substrates are difficult to print, print quality can not be guaranteed. Non-flat substrate is a micro-corrugated board printing challenge. Press to deal with the groove and spine board composed of three-dimensional structure and the corresponding structures. Another difficulty is that in fact Ink From Blanket Transferred to a corrugated necessary contact pressure, in order to have some grooves can have a clear image. This pressure is higher than the smooth surface in the ridge of the printing paper effective pressure, and it will not undermine the fine structure and stability of corrugated cardboard. This condition is a direct offset printing corrugated fine starting point. Many corrugated suppliers have to provide the necessary quality of materials to meet the uninterrupted printing. Micro corrugated board needs a direct offset blanket should have very good flexibility. It makes the printing process to increase the pressure in the spine without causing too much use of the premise of the highest printing pressure. This prevents excessive compression groove. In order to maintain the trapping and micro-corrugated cardboard-box-type stability. As the blanket makes the ink to optimize the transfer well to fine print of the highest quality corrugated board. Another question: printing through a certain pressure to transfer ink to the substrate. To make corrugated surface of the part for the corrugated troughs can also print images to complete its printing pressure to be higher than the surface roughness of the material required for the printing pressure, and this inevitably in the fine crest of the corrugated cardboard have a greater pressure , resulting in fine decrease the strength of corrugated board. To address these problems, developed a special blanket, this blanket of the elastic curve is very flat. Therefore, even when printed large imposed pressure not to make the peaks in the cardboard larger increase in pressure, which avoided the intensity of micro corrugated board damage, and to ensure accurate and fine corrugated cardboard overlay stacked formation. This blanket has significantly promoted micro corrugated board directly to the development of offset printing. Micro-corrugated cardboard direct offset, one of the most important conditions for optimal ink so that washboard effect to a minimum. Blanket development mainly to micro-corrugated board printing, through its high compressibility compensation spine and micro-corrugated cardboard printing pressure between the groove changes. However, the remaining pressure difference can still result in different levels of the Department of ridges and concave ink dot gain and trapping. This is fine when the corrugated board printing ink needs to be compensated. Print Test Show that the optimum ink significantly reduced the washboard effect. It is the completion of the wider gamut printing, proved most suitable for corrugated board printing fine. Corrugated board directly in the fine print, because printing pressure, Carton Intensity will certainly decrease, which is micro-corrugated board one of the major shortcomings of direct printing. Fine print on corrugated board strength mainly in the area of printing and printing positions. In general, with the increase in the printing area, cardboard strength decreased in proportion. Decreased about 40% of all printing; horizontal strip printed down the center approximately 35% of width 50mm; coming down along the width of 50mm is about 30%; in the upper and lower side of each stamp 50mm wide and about 37% decrease; in carton side Face the center are vertical drop of about 5% of the printing 50mm. With Printing Technology And the continuous development of technology, micro corrugated board printing will be further developed. Several micro-printing corrugated board will have more competition between, this competition also promote the development of micro corrugated board printing. Several micro corrugated board printing, will occupy its own characteristics with a certain market. Offset printed micro corrugated board direct the successful application of technology to make corrugated boxes Packaging Printing Entered a new stage of development. As a direct offset fine high quality corrugated board, low cost, printing and packaging industry can no longer ignore this technology.
