| Description: |
In order to improve the integration of blind people into society, suitable conditions should be provided for them. The expansion of Braille (BR) use could serve the purpose. Depending on the materials used for Braille, it can be formed or printed in different ways: embossing, screen printing, thermoforming, digital printing. Thus the aim of the presented paper is to determine the influence of thermal effects of screen printing inks and inks with thermo-powder on the BR inks mass change. Screen printing inks and inks with thermo-powder were chosen for the research. Carrying out the qualitative analysis of printouts with Braille, the thermal stability was evaluated by analyzing the thermograms obtained with derivatograph Q-1500. This paper presents the findings of the thermogravimetric (TG), differential thermogravimetric (DTG) and differential thermal analysis (DTA) of printouts printed on paperboard Plike and using traditional screen printing inks and screen printing inks with thermo-powder. Based on the testing findings it is determined that thermal stability of printouts printed with thermo-powder ink is higher than printed with screen printing inks. It is determined that the appropriate drying temperature range of screen printing inks with thermo-powder is 98 ºC – 198 ºC because in this case better relief of Braille dots is obtained. |
