Printability has been a point of strong interest among customers and printers. Printability is the capability of printing press to print accurately along with the substrate combination as per predetermined standards without hampering the print quality. Many digital printers are suffering from the printability related problems due to the lack of knowledge of substrates characteristics. Objective of this paper is to analyse various substrate characteristics related factors and their combined influence on printability of the dry toner digital printing presses. For the better theoretical background work in this area, a printability model already has been developed to get aware of the prominent substrate surface characteristics which affect the printability of the presses. In the present work a survey of 50 digital printers of the northern region of India was carried out to understand the awareness of digital printers about the printability behaviour of dry toner based digital printing machines in relation to the cellulosic substrate characteristics. A questionnaire was prepared to identify the print quality related problems digital printers are facing in the northern region of India on the Likert Scale of 1-5. The degree of challenge posed by various characteristics of cellulosic substrates on dry toner digital printing presses has been examined by EFA (Exploratory Factor Analysis) tool using SPSS 11.5 version. Kaiser-Meyer-Olkin value is found 0.731 and Bartlett's test of sphericity values are found (0.000) which indicated that survey method used in the research work is highly feasible and significant. Gloss and Surface strength of paper has shown the maximum contribution towards printability problems, on the other hand, dimensional stability and moisture content characteristics have shown the minimum contribution towards the printability related issues. The Exploratory Factor Analysis used in this paper indicated that there are two learning key factors (LFKs) namely; Paper Printability Index-I and Paper Printability Index-II which leads to 67.20% of the total printability results.
