Analysis of the Influence of Room Temperature and Humidity on the Printing Results of Inkjet Printing Machines at PT. Philips Industries Batam

Abstract

The implementation of the Industry 4.0 system has become a major focus for companies in Indonesian, including PT. Philips Industries Batam, which uses Inkjet Printing machines. This machine, although it has great potential in cell biology applications and biomedical research, still faces high reject problems, especially related to missing prints. This study aims to reduce the reject missing print on the Inkjet Printing machine by analyzing the effect of room temperature and humidity on printing quality. The research method involves collecting data from running production results to analyze reject patterns, as well as experiments to test the effect of temperature and humidity on printing quality. The results, temperature and humidity 22 and 23 which have a low reject percentage, namely the combination of temperature 22C and humidity 40% obtained a percentage of 0.39%, the combination of temperature 22C and humidity 50% obtained a percentage of 0.43%, the combination of temperature 23C and humidity 40% obtained a percentage of 0.49% and the combination of temperature 23C and humidity 50% obtained a percentage of 0.30%. After it is found that the combination of temperatures 22C and 23C has a low percentage of reject, then the next combination will be done with Tavg 40,41,42 and 43, Tavg 40 = Average reject result: Around 0.51%, Interpretation: At Tavg 40, the reject rate is relatively low, even the lowest is 0.25%. Temperatures of 22–23°C and humidity of 40–50% have not significantly affected the reject rate.
