The Future of Photoshop Automation: Why I Built Auto Bulk Mockup

The Problem with Manual Mockups

Every print-on-demand seller knows the struggle. You have 50 new designs, and you need to place each one onto 5
different t-shirt color mockups. That's 250 files to generate.

If you do this manually:

1. Open Photoshop
2. Double click Smart Object
3. Place Design
4. Scale & Position
5. Save Smart Object
6. Export as JPG
7. Rename File
8. Repeat x249

It's soul-crushing work. I realized there had to be a better way.

Enter Adobe UXP

Adobe's new Unified Extensibility Platform (UXP) allows developers to build plugins using modern JavaScript and React.
This was a game-changer compared to the old CEP/ExtendScript workflow.

I spent 3 months reverse-engineering how Photoshop handles batch processing to build a solution that doesn't just
"script" actions, but intelligently understands them.

Key Challenges Solved

1. Smart Object Detection

The hardest part was making the plugin "see" where the design should go without user input. I implemented a recursive
layer walker that identifies specific layer naming conventions.

2. Memory Management

Photoshop is a RAM hog. Opening and closing 100s of documents crashes standard scripts. I built a queue system that
aggressively manages garbage collection to keep the process stable even on 8GB RAM machines.

The Result

Auto Bulk Mockup Pro now powers over 10,000 Etsy shops and POD businesses. What used to take a human 5 hours now takes a
computer 60 seconds.

Automation isn't about replacing creativity; it's about removing the boring parts so you can be more creative.
