Broadly speaking, DP680 works on the same material types as DP70030, and delivers similar OPV compatibility and performance in end-to-end post applications. It is recommended that customers conduct their own tests to determine the suitability of such products for their particular purposes.
DP680 is typically applied at about 1 wet gsm (the Low or Medium setting when combined with a 74mm standard coating roller). This is similar to DP70030, though depending on the type of substrate being used, a higher coat weight may be recommended.
While DP70030 continually becomes more viscous over time, DP680’s lower and narrower viscosity window eliminates the need for viscosity adjustments.

The procedure for switching incompatible primers is documented in Priming Guidelines for HP Indigo Labels and Packaging Digital Presses How-to Guide. As of this writing, this procedure can be found on page 48 of the February 2022, Revision 01 guide (HP part number TS4OM-00005). Please contact your local HP Indigo Field Service Engineer (FSE) prior to making this switch.
Only change press settings if necessary. Start with your existing substrate settings for DP70030, and refer to the Priming Guidelines for HP Indigo Labels and Packaging Digital Presses How-to Guide, as well as the user manual for your press. Make note of existing settings prior to any change, and only change one setting at a time. This will help identify which changes are most effective for your application, and make it easier to revert to previous settings.
To optimize performance within a given material family (e.g., polyethylene), it is possible that certain press settings may need to be adjusted. These include:
The following additional documentation for DP680 is available upon request:
