06/15 Rev. 6.01-01 USER MANUAL Einrichten64-xx – 64-xx dispenser4Selecting ribbon/materialLabel materialWhen selecting the material, you must take 3 factors into account:– the abrasive behavior of the surface structure of the material;– the properties with regard to the chemical reaction when printing ink istransferred;– the temperature required to transfer the ink.AbrasivebehaviorIf the material is very abrasive, the print head becomes “worn down” quickerthan would normally be the case. This criterion is of particular importance inthermoprinting. It is not so critical in the case of thermotransfer printing, asthe ribbon can be chosen to be somewhat wider than the material, ensuringthat the print head is protected across the entire width of the material.HeadtemperatureThe same applies if the temperature of the print head is high. Material andribbon need longer to cool down, the print quality is more critical and the printhead will wear down sooner.For papers with grammages greater than 240 g, it may be necessary to makeadjustments with regard to the contact pressure and the position of the printhead.Thermotransfer ribbonFor ribbon, we recommend the following:– the reverse side of the ribbon must have an antistatic, friction-reducingcoating (backcoating);– ribbons must be specified for “near edge type print heads”;– ribbons should be suitable for print speeds of up to 12 inch/sec.(300 mm/s). Ribbon without these properties can reduce the performance of theprinter and/or the print quality as well as damage the print head!
