| Abstract | ||||
| Many government documents can be forged, even documents which are marked with "Eagle Stamp" sometimes unfortunately fake. Who is in his hands this "Eagle Stamp" sees that is enough to prevent counterfeiting and fraud completely. But what happens in reality is quite the opposite. "Eagle Stamp" is usually printed on formalized paper documents by using a relief printing plates. Such as letterpress and flexographic printing, When we need to use flexographic printing technology to print a new design structure of the "Eagle Stamp"-which build from lines and dashes in order to prevent its reproduction and therefore preventing government documents counterfeiting, we have to be careful, so the research investigated into critical parameters such as flexographic plate thickness, flexographic plate shore, line or dash thickness and the spaces between lines or dashes, digital file resolution, relief depth … etc., that help to comprehend the effect of these and other parameters on the final printed "Eagle Stamp" and to determine which of these parameters can produce a perfect ink film module to print high quality and valid "Eagle Stamp" that can be used on formalized paper documents without possibility for reproduction or counterfeiting. So our pre-press work prior to printing is designed to serve the research hypothesis, that choosing the appropriate parameters will make any attempted reproduction of our design very difficult to replicate After experimental work study, the results have shown that using photopolymer flexographic plates with compatible parameters and printing the samples with appropriate printing machine, would result in very successful and clear printed eagle stamps build in prepress stage from lines and dashes in order to achieve the research objective | ||||
