Abstract

The printing industry is a diverse industry printing on a wide range of substrates, such as paper, paperboard, polymers, metals, etc., using a broad range of printing technologies. This report covers the reasons & technique of minimizing waste in the Sheet-Fed Printing Industries covering wide range of paperboard substrates. With the case study of Radhey Krishna Offset Press, Hisar, it was found that average board wastage in any typical quality sheet-fed offset press is almost 5 %.In this paper authors tries to identify the main reasons of wastage in small scale printing industry along with the solution to minimizing wastage of paperboard & cardboard on sheet-fed offset printing industry. As substrate contribute 60-70% of total cost of production saving in 2-4 % of paperboard by minimizing the printing waste will lead to cost saving of production & increase the profit of organization.

Abstract

In this case study I analyse that a small difference in ink viscosity can produce major variations in print quality. Variation in ink viscosity affects the print quality i.e. print density decreases when low viscosity of ink and the print density increases with increase in ink viscosity but after a saturation point it starts to decrease, clogging problem comes here so dot percentage decreases i.e. density decreases. So we can say that ink viscosity and density are closely related to each other.Also the variation in ink viscosity effects on dot sharpness and dot size etc. If the ink have low viscosity then dot gain problem is created, dot sharpness decreases, mottling defect also comes. In case of high viscosity, dot sharpness increases and high viscosity sometimes causes the ink to dry inside the cell, resulting in cell clogging. This reduces the efficiency of cells to carry ink and transfer to substrates. Keeping viscosity unchanged helps to maintain print quality to great extent. Controlling the ink viscosity is very important from both quality and economical point of view.

Abstract

Quality Control in Gravure Publication in HT Burda Ltd. is important for achieving good quality in the final print. Development of Quality Control in Publication Gravure is very important considering for achieving best quality at minimum expense. This was undertaken in HT Burda plant which is the only Publication Gravure plant in India. The work flow chart has been developed for smooth flow of work&maintains the Quality Control System. For the same quality checklist are developed. Different Publications need different quality standards which are identified during this study and will be viewed thoroughly with acceptable limits&tolerance limits. For formulating the workflow first checks points are identified, they are arranged in a manner so that works can't be interrupted during operation.

Abstract

In this modern era of fast growing awareness for the concerned demand by the user it is important to standardize the process so that results could be consistent. For the same standardization of each process is needed. According to the standard laid by the organizations either locally or globally. Finally, we concluded that it is very important to note that G7 is not, on its own, an official ISO standard. However G7 is at the heart of four new ANSI standard color spaces (TR006, TR003, TR005 and TR007) and the key innovations employed by G7 especially the “near neutral” calibration concept, have significantly impacted the way modern printing standards are being written and applied. Hopefully that will be resolved in the near future with the development of internationally-agreed "unified" characterization data sets. The good news is that the latest European and American commercial printing characterization data are very similar, being based on a common origin set, but adapted for slightly different grayscale appearance. At last we concluded that the use of G7 standard are very much important for flexography. There are many independent national or international bodies/federations to compete in the modern scenario which are looking forward for global printing standards to be established and putting their effects to make the thing happens globally. They are their efforts to produce standards for each and every small elements of a process. Aim of this paper is to help the concerned industries for adopting the G7 standards.

Abstract

In this era of ever growing awareness for consistent quality demand by consumers it is important to standardize the process so that outcomes could be consistent. For the same standardization of each process is needed according to the standard laid by the organisation working for the same. Though all countries has their own apex bodies for framing and regulating the processes, ISO (International Organisation Standardisation) is an international body which are framing and producing most acceptable manner for all countries ISO is global agency looking for and provided all types of standards. At the same time ISO has standards related with Graphic Technology by committee Technical Committee 130 vide No. 12647-4 for Gravure Printing. Finally we come to say ISO standards for Gravure Printing are respected and followed by all the countries and by all organisations having desired to produce global standards.

Abstract

In universities there are many documents such as Degree, DMC and Award sheet, which requires higher degree of security features to provide sense of security to end user as well as society and at the same to build a reputation of the institution. Degree and DMC are the most important documents for students for compliance of their academic achievements. It is responsibility of university/ Educational institute to make the document secured enough so that it can't be easily counterfeited. Such type of documents requires high degree of security measures to keep them safe from counterfeiting and forgery. Traditionally universities/ Educational Institutes are printing their Degrees/ DMC on conventional papers with combination of conventional printing processes. Normally in degrees there is more number of security features in comparison with DMC. In this era of digitisation and ever growing reach of technology at lowest level, cases related with counterfeiting and forgery are reported higher in last decade specially in academic and financial world. Increase in forgery cases leads to rethink about existing security features in Degree, DMC and Education Certificate. In this research paper authors tries to evaluate and list down the security feature of Degree/ DMC in present Degree / DMC of prominent universities of Haryana and tried to recommend the their level best to some new security feature for Degree, DMC and Education certificate to make it difficult for counterfeit.
