In cases where good and fast penetration of the printing paste is essential (screen printing machines, wet on wet printing), a pure Solvitose C5 thickening will give a very high colour yield but usually rather poor penetration. In such cases it is recommended to replace part of the Solvitose C5 by a thickener having a higher penetration power, e.g., an alkali resistant alginate, a galactomannan derivative (e.g., "Solvitose" Gum OFC). Such a combination will give a somewhat lower colour yield but better penetration of the printing paste. |
