One sticker is a toy; a set is a product. LINE sets are made of many images, and doing them one at a time is slow and inconsistent. Batching — preparing several at once with the same settings — is how you finish a set that looks coherent. The HailouTec cutter fits batch thinking whether you start from a grid sheet or several separate files. For laying out a whole set on one canvas first, see the grid template guide →
Why batch?
- Consistency. Same size, same style, same transparency across the set.
- Speed. One workflow instead of reinventing it per image.
- Fewer errors. A repeatable process catches mistakes early.
- Less rework. Fix the method once, apply to all.
Method A — Split a grid sheet
If your art lives on one grid image:
- Load the sheet into the cutter.
- Let it detect the grid and split into cells.
- Apply the same resize (320×320) and background cleanup to each cell.
- Export all cells as transparent PNGs.
This is the fastest batch path when you already arranged art on a grid.
Method B — Process separate files
If your stickers are individual images:
- Crop each to its subject with the same margin rule.
- Resize all to 320×320.
- Clear backgrounds with the same tolerance.
- Export all as PNG.
Keep the settings identical so the set looks uniform.
Keep a batch checklist
- Every file is 320×320 PNG with transparency.
- Backgrounds cleared (no white box).
- Consistent padding and centering.
- Shared visual style across the set.
- Tab (96×74) and popup (240×240) generated if required.
Common batch mistakes
- Mixed sizes. Some 300, some 320 — looks off. Standardize.
- Inconsistent backgrounds. Some transparent, some not. Check each.
- Style drift. Later stickers look different from early ones. Keep a reference.
- JPEG exports. One slip to JPEG adds a white box. Export all PNG.
FAQ
Can I really do a whole set at once?
If your art is on a grid, yes — split and export in one pass. Separate files are processed per image but with identical settings for consistency.
What size should every sticker be?
320×320 for the main canvas. Tab and popup sizes are in the size guide →
How many stickers make a set?
LINE requires a minimum per set; prepare enough coherent images rather than padding with weak ones.
Does batching affect quality?
Not if settings are consistent. Batching improves uniformity, which is what a good set needs.
