STUDY OF DOT GAIN IN DIFFERENT DOT SHAPES OF HALFTONE ON PRINT QUALITY BASED ON DRY TONER ELECTROPHOTOGRAPHY DIGITAL PRESS

Electrophotography is a non-impact printing process. Printing of an image in continuous tone is not possible by printing machine. Therefore, image has to break in halftone dot to print through any printing process. Digital printing is not exceptional. There are different halftone dot shapes available like square, elliptical, diamond etc. This leads a curiosity in mind to study the effect of different dot shape on print quality. In this paper, we considered the impact of various dot shapes of halftone on print quality (dot gain) in dry toner electro photography printing process in which different halftone shapes are used for printing. The sheets were printed with different halftone dots (diamond, elliptical, square). Dot gain is measured at different locations of different halftone dot shapes. The collected data is represented in a meaningful way so that clear difference can be seen.
