Abstract

Reverzibilna termokromna (TK) tiskarska boja otisnuta je ofsetnom tehnikom tiska na četiri različite tiskovne podloge. Prilikom određivanja kolorimetrijskih svojstava, svaki uzorak je zagrijavan od 35 oC do 75oC i tada ponovno hlađen do 20oC. Kako boja TK otiska ovisi o temperaturi, što ima za posljedicu histerezu boje, uočeno je da na histerezu boje utječe i tiskovna podloga. Kako bi se objasnio utjecaj podloge na kolorimetrijska svojstva, određeni su adhezijski parametri boje na papirima. Međupovršinska napetost, termodinamički rad adhezije te močenje mogu dati bolji uvid u ponašanje termokromne boje ovisno o papiru na kojemu su aplicirane.

Abstract (english)

Reversible Thermochrome (TC) printing ink is printed by offset printing on four different printing substrates. When determining the colorimetric properties, each sample was heated from 35 oC to 75 oC and then cooled again to 20 oC. As the color of the TC prints depends on the temperature, which results in color hysteresis, it is noted that the color hysteresis is affected by the printing substrate. In order to explain the influence of the substrate on the colorimetric properties, paper adhesion parameters were determined. Intermediate tension, thermodynamic adhesion and wetting can give a better insight into the behavior of the thermocrome paint depending on the paper on which they are applied.
