Gelatin has been known since antiquity and was first used as an adhesive in the year 6000 BC. Gelatin is widely used for coating food and photography. The most abundant sources of gelatin are pigskin, cowhide, pork, and beef bones. The food industry has increased the number of applications of gelatin to replace synthetic materials. Gelatin is derived from collagen that is processed by means of hydrolysis, when almost the entire protein fraction consists of amino acids. Gelatin is generally used for pharmaceutical and medical applications, as well as biodegradability and biocompatibility gelatin on the body. Gelatin is also clinically proven to be used a matrix. Gelatin is dissolved in water can be used as a substitute for inkjet printer ink DOD. Ink Jet Drop on Demand (DOD) is a printing tool. Ink Drop On Demand ink jet form a combination of serval materials include polymers, solvents and pigment. Fluid viscosity plays an important role in the rate gelatin solution flow rate on the printer head. The results of the study will be expected to replace the conventional ink with biocompatible. The material used in this study was gelatin (E-Merk, Germany) with distilled solvents. Gelatin was dissolved in distilled water and stirred using a magnetic stirrer. Stirring was carried out for 3 house, 500 rpm, 40%. Gelatin solution viscosity was measured using Ou=stwald Viscometer. The cartridge is inserted into the gelatin solution by injection. The results showed that the concentration of 1% and the optimal concentration can pass through the cartridge with out over flow and blockage. Printing on paper also shows that a 1% gelatin solution has precision and sharpness better. It can be concluded that the gelatin solution can be used as a substitute for conventional ink ink with good characteristics. A concentration of 1% gelatin viscosity showed that the optimal concentration as printer ink.
