Du, Prof. Dulce Ramos<br/>The study entitled "Production of Stamp Ink from Malabar Spinach (Basella rubra Linn.) was undertaken to produce stamp ink from Malabar spinach fruits. This study aimed to (a) determine the color, odor and viscosity of stamp ink as solution; (b) determine the clarity, lightfastness, smudging and intensity of the color as printed on paper of the produced ink; (c) test the acceptability of the extracted ink out of Malabar spinach fruits; and (d) determine the cost of production of stamp ink set and its comparison to commercial stamp ink set. The study was conducted in Alulod, Indang, Cavite from July to November 2003.<br/>The treatments used in the study were; Treatment 0 (commercial stamp ink), Treatment 1 (25 mL Malabar spinach extract), Treatment 2 (25 mL Malabar spinach extract + 7.5 mL denatured alcohol + 2.5 mL vinegar + pinch of table salt + .25 mL iodine), Treatment 3 (11.25 mL Malabar spinach extract + 3.75 mL distilled water + 7.5 mL denatured alcohol + 2.5 mL vinegar + pinch of table salt + .25 mL iodine); and Treatment 4 (7.5 mL Malabar spinach extract + 7.5 mL distilled water + 7.5 mL denatured alcohol + 2.5 mL vinegar + pinch of table salt + .25 mL iodine). Each treatment was replicated three times for optimum results. The samples of ink were presented to thirty judges for evaluation. General acceptability, clarity, light fastness, smudging and color of ink as solution and as printed obtained highly significant differences in the results which can be attributed to the different ink concentrations. However, non-significantly different results were obtained from odor and viscosity. It was also proven that Treatment 1 (pure Malabar spinach extract) can also be utilized as stamp ink. In terms of economic feasibility, Treatment 4 obtained the lowest cost of production of only . 37.62
