Abstract

Uloga boje vrlo je često ključan faktor pri izboru nekog proizvoda, a vrsta podloge može

utjecati na drugačiji doživljaj iste boje. Cilj ovoga rada je istražiti utjecaj premaza na papiru

na efekt promjene triju termokromnih ofsetnih boja različitih aktivacijskih temperatura

(27°C, 45°C i 63°C). Uzorci će biti zagrijavani/hlađeni pomoću termostatičnog cirkulatora,

a njihove kolorimetrijske karakteristike mjerit će se spektralnim fotometrom u različitim ciklusima ovisno o temperaturi aktivacije. Kako bi se prikazale dinamičke karakteristike promjene boja pratit će se njihove promjene preko histereza kako bi se utvrdilo postoje li razlike

u dinamici promjene boje ovisno o karakteristikama podloge.

Abstract (english)

The role of color is often a key factor when choosing a product, whereas the type of substrate

can have an effect on how we experience color. The aim of this paper is to investigate how

paper coatings effect the change of three thermochromic offset inks with different activation

temperatures (27°C, 45°C and 63°C). The samples will be heated/cooled using a thermostatic

circulator and their colorimetric characteristics will be measured by a spectral photometer in

different cycles depending on the activation temperature. In order to show the dynamic characteristics of color change, the changes will be monitored via hysteresis to determine if there

are any differences in the dynamics of color change depending on the characteristics of the

substrate.
