Comparative Analysis of Print Quality in Dry Toner and Liquid Toner Based Digital Printing Techniques on Art Coated Paper

Print Quality has been a point of strong attention among printer among India also it is highly sensitive point of debate among foreign printers. Objective of this research project work is to compare various quality control parameters in Dry Toner and Liquid Toner based digital printing presses available in local market. A master test chart was prepared having various elements such i.e. Colour Control Strip, CMYK- Solid Patches, G.J.U. logo as Graphic, Halftone images, Tint patches of different colours. The test chart was printed on Art Coated paper with the help of Dry Toner and Liquid Toner based digital printing presses available in local market. The test chart was analyzed to check the print quality with Spectrophotometer. The result indicated that Solid Ink Density was more in Black colour in Dry Toner based digital printing technique. Print Contrast was more in Magenta in Liquid Toner based digital printing technique. Dot Gain was maximum in Black colour in Dry Toner based digital printing.
