When you are running a higher volume Direct To Garment printing facility, you are printing a LOT of shirts every day. You need to ensure that you are up and running while controlling all of the variables. You don’t want to waste pretreatment or have downtime on your DTG pretreating department that can shut down your ENTIRE DTG printing facility.

The MAXX is truly a production oriented pretreatment machine with production rates of 90-135 shirts per hour on a single Viper MAXX. In addition, you can utilize the BUILT-IN bar code scanning feature to implement customized pretreatment areas and application amounts for each style of shirt and individual customer order. This enables you to more efficiently apply pretreatment, use less fluid, and increase productivity while maintaining up-time.

If a single point pretreatment application is running your entire DTG printing operation, what happens if (when) there are issues with the pretreatment machine? Your entire production shuts down. Utilizing multiple Viper MAXX pretreatment machines means if you ever do have an issue, you can continue pretreating and printing DTG shirts. Efficiency, versatility, and productivity is what the Viper MAXX is all about. Making DTG pretreating easier – on every shirt.
