Understanding Print File Generation

When customers place orders with customized products, Chamevo automatically generates print-ready files for production.

How It Works

1. Customer completes checkout with customized product(s)
2. Chamevo generates a print file for each product
3. Files are saved and attached to the order
4. Order confirmation email is sent

Server Requirements

Minimum Requirements (see Requirements):

PHP Version: 7.0+
PHP Memory Limit: 256 MB minimum
PHP Post Max Size: 64 MB minimum
Required PHP Extensions: Imagick, ZipArchive
Web Server: Nginx or Apache

Additional Settings for Print File Generation:

For handling multiple products or complex designs, you may need to increase:

max_execution_time = 300  (increases from default 30 seconds)
memory_limit = 512M  (increases from minimum 256MB)

Common Issue: Timeout Errors

The Problem:

When a customer places an order with multiple products, the system needs to create a separate print file for each one. If the products are complex (lots of colors, layers, or custom elements), generating these files can take a while.

Your WordPress server has to wait until all print files are ready before completing the order. Most servers have a time limit — usually around 30 seconds. If the print files take longer than that, the server runs into a timeout error and the order is not processed.

Signs of Timeout:

• Orders stuck in "pending" status
• No confirmation email sent
• "504 Gateway Timeout" or "500 Internal Server Error"
• PHP errors: "maximum execution time exceeded"

Solutions

Increase Server Limits:

Contact your hosting provider to increase timeout and memory limits:

max_execution_time = 300
memory_limit = 512M

Optimize Products:

• Simplify design templates (fewer layers)
• Compress images before uploading
• Set canvas size limits

Optimize Export Settings:

• Use 300 DPI (sufficient for most printing)
• Avoid unnecessary export formats

Upgrade Hosting:

• If issues persist, consider VPS or dedicated hosting
• Ensure your server meets the minimum requirements

Troubleshooting

Check Error Logs: Look in /wp-content/debug.log for execution time or memory errors.

Test Systematically:

• Single simple product
• Single complex product
• Multiple products

Contact Support:

• Hosting Provider: For server timeout/memory limits
• Chamevo Support: For print file generation errors
