Abstract

One of the main components of the fountain solution used for the offset printing technique is isoprophil alcohol (IPA), which is related to its function as a surface tension reducing agent, cooling agent for printing plates and at the same time having anti-bioorganic function. However, complaints have also been made about the weaknesses in the use of IPA related to odor, toxicity and too high evaporation rate during its use. Therefore, in this article, IPA is compared to the "alcohol-free" type when used in the field as a wetting solution mixture using a KBK offset printing machine to produce magazines using of AP 115 paper. The difference in the use of the two surfaces the tension reducing agents are identified by the waste parameters that are used, generated during consistent printing under controlled process conditions. The results obtained indicate that the use of IPA is always higher, but the use of `` non alcoholic '' tends to be more stable in controling the process.Keywords—Isoprophil Alcohol (IPA), alcohol-free fontain solution, offset printing

Abstract

Ink quality study have been observed on ink products in the market as a right confirmation of ink users for printint production. The study is also conducted to ensure the suitability of the ink with the printing materials and machines used by consumers. The observation was conducted on two brands of ink from the same manufacturer. The quality data studied were viscosity, spreadability, drying time, density and L*a*b. The results show that, although both inks are produced by the same manufacturer and are intended for the same market, there are differences in quality, namely one has a higher viscosity and a faster drying time than the other.Keywords—quality of printing ink, viscosity, spreadability, drying time, density and L*a*b

Abstract

In-depth observations have been made on the web printing process for newspaper production. Observations were made to identify problems related to the tension of the roll paper used in the production of newspapers. The problem of roll-paper tension is observed from the main material, the upstream process (Reelstand Unit), the printing process and its supporting units such as the wetting unit, inking unit and in the folder unit which is a contineous process. From observing the problems in the printing process, the causes and solutions to the problems were identified which were then used as an operating standard reference for the newspaper production using a web offset printing machine.Keywords—web offset printing machine, newspaper, paper tension

Abstract

Duplex cartons will be one type of carton that is widely used as a primary or second packaging. Duplex cartons have hygroscopic properties that can be salted on the physical and quality of the carton duplex. The value of this Final Task paper is the way of quality of cardboard in the field and the efforts of the process and who is in the field champion of The Indonesian National Standard (SNI 0123:2008). While the purpose of this writing is For those who know the process of creation of duplex carton quality 350 gr / m2, To understand the results of the creation of the quality of both duplex cartons from different companies, and For to dye the quality of cartons 350 gr / m2 in the market of different companies. Which method in writing this Final Task paper is the Task Related to Indonesian National Standards (SNI 0123:2008). Located from the creation and duparan quality of its own results, the two duplex cartons there are different qualities, for the production of PT X. Cobb value which is passionate and quality questions according to SNI 0123:2008 while for the production of PT Y. brightness value who can not be questioned sni 0123:2008. SNI 0123:2008 was prepared with the purpose of standardization, but the standard provisions were not met and not supervised in companies that do not apply sni standard 0123:2008, but in companies that apply sni standard 0123:2008 found also incompatible, therefore it is recommended to be carried out monitoring periodically.Keywords— Quality duplex carton, Duplex Carton, SNI 0123:2008

Abstract

350-gram duplex cartons is a popular packaging material used by entrepreneurs because it is affordable, recyclable, and harmless to humans. The two main manufacturers that provide these packaged products are found in the market. In order to assist the government in providing quality assurance for consumers, the packaging materials are physically tested in accordance with SNI 10123: 2008. The quality testings include the grammature of cardboard, thickness, brightness, water absorption, oil absorption, pulling power of paper/cardboard, water content, paperboard folds, and mass density of paper/cardboard, by means of tests that have been provided by the National Standar Nasional. Indonesia (SNI). The results showed that one of the manufacturers did not meet the requirements for the brightness, while the other manufacturer did not meet the standards for the water absorption.Keywords—Resistance, Paper, Mattpaper
