Production of Varnish with Coconut Oil-Based for Environment

Abstract

This research aimed (1) to produce varnish, offset base oil, (2) to test the properties of the varnish, offset base oil, (3) to analyze the print quality of varnish, offset base. Coconut oil operations conducted three steps, which are (i) the manufacture and formulation of ink offset printing base oil, (ii) testing of inks, and (iii) quality prints from the ink off set base oil. The process of mixing varnish by using coconut oil was one of ingredients to produce varnish with Coconut Oil-Based which were the subject of testing issues such as tack, viscosity, ink flow and ink spread in order to compare with commercial offset printing inks. The research results can be obtained with the appropriate formulation of using a coating containing coconut oil base solvent. For the production, the best blend was 50% coconut oil, 35% phenolic resin and 15% solvent oil. Tack values were found to be less than commercial coatings. And tested the properties of the coating with coconut oil base solvent. Viscosity, Ink Flow, Ink Spread of Coatings with Coconut Oil Base Solvents were found to be less than those of commercial coatings. Coconut Oil Quality Test Results On 2-sided 230-page art paper, the average gloss is 82.30 gloss unit (GU). On 230-page art paper, the average gloss was 97.20 gloss unit (GU) and the print quality of coconut oil On 260 sheets of art paper, 260 grams of gloss is 82.50 gloss unit (GU). On 260-page art-card 260 gsm, the average gloss is 97.60 gloss unit (GU). The satisfaction of operators in the use of coconut oil The overall quality of printed matter was 4.48. Satisfaction was at a high level. Consumers' satisfaction in using Coconut Oil Coating Agent Post-print quality satisfaction Overall, the mean was 4.31. Satisfaction was high.
