手溫型變色防偽油墨是指在3436℃下，能發生變色效果的油墨。按照變色方式的差異，又可分為單變色可逆、多變色可逆和多變色不可逆熱敏防偽油墨。

熱敏油墨是種能隨溫度變化而使顏料顏色發生變化的特種油墨，即油墨在不同溫度時最示出不同的顏色，又稱溫致變色油墨。

熱敏材料按類別可分為無機類、有機類、液晶類三熱敏油墨受熱發生顏色變化，主要取決於變色顏料，因為這些顏料加熱前後出現的顏色變化截然不同，

並以此達到防偽目的。根據變色所需溫度的不同，可以分為手溫型變色防偽油墨和高溫變色防偽油墨。

手溫型變色防偽油墨是指在3436℃下，能發生變色效果的油墨。按照變色方式的差異，又可分為單變色可逆、多變色可逆和多變色不可逆熱敏防偽油墨。

日前國內已經開發出多種手溫型單變色可逆油墨和高溫單變色可逆防偽油墨。可逆型油墨在熱源撤去後，油墨顏色又可恢復原狀；

不可逆型油墨即在熱源撒離後，油墨顏色不可復原。
