Sticker Production Automation Tool

This project focused on the production-side file preparation work required before sticker printing and contour cutting. The individual actions were not complicated, but they were repetitive, error-prone, and heavily dependent on operator habits.

The team needed an internal tool that could turn that manual preparation routine into a faster, more standardized workflow that operators could run with less repeated effort.

I led the implementation of an internal desktop tool that converted scattered preparation steps into a more guided workflow.

• Built a PyQt6-based desktop workflow that operators could actually use day to day.
• Aligned the tool around the real production objective: print-ready and contour-cut-ready outputs.
• Turned repeated file-prep work into a more consistent sequence instead of leaving it to manual operator repetition.

Small repeated actions were creating large hidden costs

Each preparation step looked simple in isolation, but the overall routine became expensive when repeated across many orders. The biggest issue was accumulated repetition rather than algorithmic complexity.

Output consistency depended too much on manual habits

Production quality is sensitive to file preparation differences between operators. A manual process increases the chance of avoidable variation and cleanup work downstream.

Internal workflow tools still had to feel usable

Even though the tool was internal, it needed to be practical enough for regular operators to adopt. A script-only solution would not be enough if the goal was daily workflow use.

I packaged the workflow as a desktop tool instead of isolated scripts

Using Python and PyQt6, I built an internal interface that operators could run directly. That made the workflow easier to adopt in real production settings.

I organized the process around the production sequence

The tool accepts source design files, applies the required preparation steps in order, and produces outputs that are ready for printing and contour cutting. This keeps the workflow aligned with the real downstream task.

I used automation to standardize repeated preparation

By moving repeated actions into the tool, the workflow became more repeatable and less dependent on individual operator habits.

The tool follows a simple operator-facing sequence:

1. Operators load the source design files.
2. The tool applies the required preparation steps in a fixed order.
3. Output files are generated for printing and contour cutting.
4. Operators move into the next production step with less manual cleanup or rework.

This project reinforced a practical lesson: some of the highest-leverage engineering work is invisible to customers. If an internal tool saves operator time, reduces mistakes, and shortens the production path, it creates real business value.
