This guide provides a comprehensive overview of integrating Brother GTX Pro and Pro Bulk machines for Direct-to-Garment (DTG) printing, detailing the necessary files, workflow configuration, and execution of print jobs.
System Overview
To automate the printing process, the system requires three specific files generated during the workflow:
XML File: Contains print settings (ink combinations, platen size, etc.).
PNG File: The high-resolution asset to be printed.
JSON File: The "instruction manual" that tells the system which machine to use and which XML/PNG files to pair together.
For more detailed information on the XML file settings, refer to the XML guide.
Workflow Configuration
Before printing can occur, you must configure your workflow to generate the necessary assets.
File Naming Convention
While names can be customized, we recommend following this standard convention for consistency:
XML/PNG: GCWB_DTG_[JobID]_[PrintArea].xml (e.g., ..._front.xml)
JSON: GCWB_[JobID].json (This is mandatory for the system to locate the job during scanning).
Setting Up Print Parameters (XML)
The XML file defines how the Brother machine handles the fabric. You will find all the settings to be defined here.
JSON Routing and Machine Mapping
The JSON file acts as the router. It maps a specific Print Area (e.g., "Front") to a machine (e.g., "GTX Pro Bulk") and assigns the corresponding XML and PNG files.
You can support multiple machines for a single print area by defining different machine mappings within the same JSON file.
Production Station Configuration
To send files to the physical printer, you must configure the Work Settings on the local production computer.
Machine Mapping
Go to Work Settings in the application.
Map the Virtual Machine (defined in your JSON/Workflow) to the Physical Printer installed on your Windows machine.
File Access Methods
There are two ways to get files from the cloud to your local printer:
Method | Description | Configuration |
Local/Network Sync | You use a third-party tool to sync SFTP files to a local drive | Provide the Input Folder path where the files are already synced. |
On-Demand SFTP | The system downloads files only when the job is scanned. | Gelato admin user will enable the SFTP Connection for you. |
Output Folder
Provide the path to a folder on the local computer where the system can store the ripped image file.
Executing a Print Job
Open the Production Station interface.
Scan the Job Ticket (the Job ID).
Complete any required precursor steps (e.g., Pre-treating).
The system automatically downloads the files (if using On-Demand SFTP) and processes them.
A combined .ARXP file is generated and sent directly to the Brother printer queue.
FAQ
What files are required for the printing process?
You need an XML file for print settings, a PNG file for the asset, and a JSON file for machine mapping.
How do I configure the production station?
You need to map the virtual machine to the physical printer in the Work Settings of the application.
Can I use multiple machines for one print area?
Yes, you can define different machine mappings within the same JSON file.
