Abstract

In the modern era, digital printing has been dominating printing process to print on veriety of paper substrates. Electrophotography is one of the commonly used technology or method in digital printing process. The emerging trends in the field of digital printing take over the position of traditional printing processes which requires the scrutiny of the print quality parameters. The total digital controlling of the printing process gives a hypothesis of achieving the consistent print quality in all prints. This article is scrutinizing that hypothesis by conducting the instrumental (Techkon Spectro Dens Premium spectrophotometer) measurement of colorimetric and densitometric tonal values and quality parameters of the print on coated and uncoated paper which is printed on daily basis. The results show that the Delta E (colour variation) is higher in uncoated papers as compared to the coated prints. Solid ink density and print contrast of black colour has better consistency on uncoated paper and print contrast of all colours on coated are also subjected tothe variations. The solid ink density of yellow colour on coated paper shows highest densitometric value consistency.

Keywords

Solid Ink Density, Print Contrast, Delta E.

Abstract

Newspaper is most popular mass media in all over the world. Mostly newspapers printed on daily basis and circulated. A newspaper consist loose sheets and these sheets are combined during production. Web-offset is used to print production of newspapers. Numbers of copies printed depends upon area of circulation and numbers of readers. Print quality is a factor that attracts the readers, so that a good print quality helps to increase the sale of the newspapers. Mostly newspaper presses in India are using Web Offset machines. There is a lot of difference in print quality of the various newspapers. This study can help the newspaper printing press to improve the print quality and promote their sales and also help the readers to choose the better quality newspaper from the available newspapers. The print quality of various newspapers are analysed with some suitable tools and methods.
