Abstract

The waste control in the printing industry is very essential. Observation shows that waste created in printing houses was enormous-a lot of papers, inks, darkroom chemicals, films, and plates. Generally paper (News Print) cost is 67% of the whole cost of newspaper. The practice has become a normal trend for the employees and management of these printing houses, without realizing the effect waste poses on the customers, the company, the environment, as a whole. The quantity of waste created affects the production cost, and its disposal poses a threat to the environment. The disposal of printing waste doesn't cost printing houses financially. With the present case study of Daink Bhaskar press, Hisar, it is found that the standard wastage percentage in any newspaper industry can be reduced considerably upto level of 4.5 %.

Abstract

The selection of print factors and controlling over them determines the colour quality and resulting printed paper colour Lab values. The present paper discusses about the colour value variation and its solution based on the study done for printing on art paper with different sheet-fed offset inks because several factors like dot shape, screen ruling, screening affects the colour value variation to some extent. In this study, a simple experiment is conducted to show how colour value variation can be caused due to various different factors. We have considered same substrate (Imported Art Paper) printed with a family of inks namely Speedset ink & Art-paper ink, having various print factors, assuming that these sheets are printed and measured under same ambient conditions with Adast Dominant 725E and Gretagmacbeth spectroeye respectively. Under such assumptions, colour values measured from art paper is described by Lab, ΔELab, and density graphs. These graphs are used to perform a parametric/comparative study to describe how different factors affect the LAB and Density values and colour quality in respect of both inks. It is demonstrated that different factors can significantly affect the colour values variation with respect to both inks.

Abstract

In this world of ever growing day by day awareness for every consistent demand by consumers it is important to standardize the printing process so that outcomes could be good and effective. For the same the use of standardization of each process is needed according to the standard laid by the organization globally or worldwide. If you want to deliver the product across the market your preference should be follow global standards for your organization and to get the process checked and certified by independent agencies or body for your process as well. There are some independent national or international bodies/federations to compete in the modern scenario which are looking after for global printing standards to be established and producing their effects to make the thing happens worldwide. They are their efforts to produce standards for each and every small elements of a process. Aim this paper is to help the individuals, smalls scales or medium scale industries for using the standards.

Abstract

The main aim of this study is to reduce the print-waste and avoiding the problem of lack of finished product. Different jobs have been tracked to identify the factors responsible for shortage of finished product. During this we observed various types of printing troubles which causes wastage and shortage of finished product. To reduce these problems, it was necessary to understand the working principle of press and wastage reduction methods. This study work provides the reference for identifying various defects which generally occur during production.

Keywords

Finished Product, Wastage, Defects.
