Maybe the standard PSI causes more inventory hassle than you want to deal with since each size offers 3 colors of pre-inked cartridges. Maybe the cost is still a little too high for you to adopt the original PSI Self-Inking Stamp. Introducing....."Z" Style foam and cartridge for the PSI Self-Inking Stamps. Reduces your ink cartridge inventory by 80% and your cost by 10%. The "Z" style uses a two-layer foam where a thin cartridge is adhered to a thin foam. This helps reduce our cost with out sacrificing print quality. The migration time is 30 minutes........Yes! Your stamps are ready in 30 minutes with our standard oil based ink.

Ink load for PSI “Z” Style is the same as our standard PSI’s that utilize a pre-inked cartridge. PSI’s attain 3-5 times more impressions than traditional self-inkers.
