Schulze PRETREATmaker IV – Pretreatment Application Machine for DTG (Used)

Schulze PRETREATmaker IV – device for applying pretreat liquid for DTG (used)

The Schulze PRETREATmaker IV is an automatic device for applying pretreatment emulsion for DTG, intended for print shops that want a repeatable and precisely adjustable application of liquid before printing (especially for white underbase on dark materials). The device is used, in excellent condition, and works flawlessly.

Key production advantages

Adjustable application and consumption optimization

The system uses 4 precision nozzles that can be controlled individually. The application area can be adjusted in width and length (in steps), which also enables work on smaller designs and reduces unnecessary liquid consumption.

Carriage motion control and spray mode

The carriage is driven by a stepper motor; one-way and two-way spraying is enabled, as well as adjusting spray intensity by setting the carriage speed.

Touchscreen and operator information

On the touchscreen, the operator monitors key parameters such as liquid consumption, nozzle status, and fluid levels, which helps standardize the process and ensure repeatability between batches.

Filtration, automatic cleaning, and liquid switching

An additional filter reduces the possibility of impurities building up in the system. The device features automatic nozzle cleaning and automatic pump cleaning; in addition, a switching valve enables an easy changeover between two different liquids (e.g., pretreat + water).

Integration into the workflow

Connectivity via an interface is supported (barcode use possible), which is useful for a faster workflow in organized production.
