In the age of science and technology, the latest scientific inventions have given rise to various technologies in each and every aspect. Day by day, newer and newer technologies are entering in the field of printing technology. Digital printing is one among those inventions and latest technology which revolutionized the entire world of printing. AlsoSheet-fed offset printing is one of the most dominating printing techniques since ancient time. It also facilitates working on large variety of surfaces including coated and uncoated paper, besides these factors sheet-fed offset printing have grown widely and made a special impact in print market. This analysis establishes relationship between the print qualities of both types of printing substrates by sheet-fed offset printing. Finally the presented analysis system is used for an objective comparison of dot gaini.e. Tonal Value Increase in Sheet-fed offset and Digital Printing on coated and uncoated paper.
