The list of recommendations is based on experiences of ink manufacturers and end users and no suitability guarantees are given. The printing result may vary significantly depending on the local printing conditions (like ink layer, ink curing) and the process itself. Especially UV offset multicolour printing on thermal paper is a very challenging process. Thus, it is recommended to always have printing trials when selecting a new ink or printing a new paper grade. Furthermore trials on thermal printers are recommended. For further assistance on technical issues related to the printing of the thermal grades, please contact the appropriate ink manufacturer or the technical customer service of Jujo Thermal: jujosales(at)jujothermal.com.
