Line Output Quality Assessment of Digital Printers
This paper mainly focuses on the quality assessment of line output of digital printers.Line patterns with various color,width and of two direction(Horizontal and Vertical) have been carefully designed to constitute a test chart.And then printed with a typical color inkjet printer (Epson 1390)and color laser printer(HP4700) separately.The substrates including common print paper and glossy photo paper.Based on the ISO13660 standard,a measurement software was programmed in Matlab,and was used to test the line characteristics.Through analyzing the test results,some conclusion can be drawn:The outputted lines are generally wider than the designed line width.Raggedness of horizontal lines and vertical lines show significant differences,this has a great deal to do with the imaging mechanism of the printer.The ink and surface of the substrate have great influences on blurriness of the line edge,for example,the coating of a glossy paper usually help the pigrnents spreading on the substrates,but this will aggravate the blurriness of the line edge.
