AI image generation has cut hang tag design from days to minutes, and many small brands now feel that design no longer requires outside help. The rules at the printing end have not changed: the file decides the product. A beautiful image on screen may contain nothing that can go straight onto a press — it is made of pixels rather than vectors, its text is drawn rather than typeset, and its colours are emissive RGB rather than ink-based CMYK or spot colour. This article explains how those three facts affect real production of hang tags, woven labels and packaging bags, and what to do before handing an AI file to a factory.
1. Three Structural Limits of an AI File
The first is pixels versus vectors. AI output is a bitmap: scaled up to final size its edges soften, and the more you enlarge it the worse it looks, whereas the logo, rules and type on a hang tag must be vector to stay crisp through die-cutting and foil stamping. The second is text. Generative models draw letterforms that look like characters; strokes connect the wrong way, Chinese characters gain or lose strokes, and the pairs 6 and 8, or 1 and 7, are the easiest to confuse. The third is colour. A screen mixes light and can show very bright greens and oranges; ink mixes pigment and cannot reproduce them, so the colour must be mapped to the nearest achievable build — skip that step and the proof reveals something that feels entirely different.
2. Resolution: Calculated at Final Size
The familiar 300 dpi figure only holds under one condition: it means 300 dpi at final size. The same 1024-pixel square is adequate for a 35 by 55 millimetre hang tag, but at 60 by 120 millimetres the long edge drops to roughly 217 dpi and the softening becomes visible. So judge an AI image by measuring the finished size first, then working back to pixels.
| Finished hang tag size | Minimum pixels at 300 dpi | 600 dpi for fine rules, small type, foil art |
|---|---|---|
| 35 × 55 mm | 413 × 650 | 827 × 1299 |
| 40 × 70 mm | 472 × 827 | 945 × 1654 |
| 50 × 90 mm | 591 × 1063 | 1181 × 2126 |
| 60 × 120 mm | 709 × 1417 | 1417 × 2835 |
3. Type Must Be Reset, Not Reused
This is the step most often skipped and most often fatal. Text inside an AI image is a picture, not text: no one can edit it in prepress software, adjust its tracking or confirm whether a character is wrong. A misspelt brand name, S/M/L mixed up with XL, a missing line in the wash instructions — problems of this kind hide at proofing and surface after mass production, when the whole lot is scrap. Treat the AI image as a background or graphic element and reset every word in layout software with a licensed font, checked character by character against a list.
- Remove the type from the image: generate with the text area empty, or paint it out later, so nothing that merely looks like writing stays on the printed surface
- Reset with a licensed font: confirm commercial use is allowed — free for personal use is not free for business — and put the font name in the spec so the next run can be reproduced
- Outline on delivery: converting type to curves prevents a missing-font problem, but keep an editable source as well, so prices and sizes can be changed later
4. Colour: The Screen Promises What Ink Cannot
The RGB gamut is wider than CMYK, especially in saturated greens, oranges, purples and fluorescents: vivid on screen, flatter and duller in four-colour print. That is physics, not a defect. Three ways to control the result: specify brand colours as Pantone references rather than screenshots; build large areas of deep black from all four colours or a spot black, so single black does not read grey; and give reversed-out small type enough stroke weight, since heavy ink coverage eats it first. Hang tags often use kraft or cotton paper, which is itself coloured, so any ink printed on it shifts — for those jobs, proof on white stock first, then on the target paper.
5. Matching the Process: Foil, Emboss, UV, Woven
The metallic sheen, relief and gloss in an AI image are drawn effects, not process artwork. Real foil stamping or embossing needs a separate solid vector version in one colour. The usual misunderstanding is thinking a screenshot of the metallic area is enough: the factory receives a gradient bitmap and can only burn a dot pattern into the die, which stamps out mottled.
| Process | What the file must contain |
|---|---|
| Foil stamping | One-colour solid vector; rules no thinner than 0.25 mm, type no smaller than 3 mm high, kept clear of heavy ink areas |
| Emboss / deboss | As above, plus the paper grammage: thin stock cracks when pressed deep, so keep it shallow under 300 gsm |
| Spot UV / varnish | A separate black plate marking the varnished areas, with 0.5 mm registration allowance at the edges |
| Die-cutting and hole punching | Die line on its own layer marked non-printing, with 2 to 3 mm bleed |
| Woven label | Colour count is limited by loom and yarn; fine rules and small type must be enlarged to weaving resolution, with the real minimum settled at sampling |
6. Delivery Checklist: Turning an AI Image into Print Artwork
- Image: at least 300 dpi at final size, converted to CMYK; solid backgrounds as colour values, not screenshots
- Type: all reset and outlined, plus an editable source file and a note on font licensing
- Colour: spot colours named by Pantone number, four-colour areas given as values, not just an image
- Process plates: a separate black plate for foil, emboss and UV each, clearly named
- Structure: die line on its own layer, 2 to 3 mm bleed, hole position and diameter dimensioned
- Version: file name with version and date, one change at a time, so three factories do not hold three versions
7. Copyright and Brand Risk
Copyright in AI-generated output is still being settled in most jurisdictions, so registering a purely AI-made image as a trademark, or claiming exclusive use on a hang tag, carries real risk. The safer pattern is to treat AI as a concept tool — use it for direction and composition — and have a designer redraw the final brand mark as vector, keeping a record of the process. Two traps to avoid: generated graphics that closely resemble a well-known brand mark, and commercial marks that imitate a living designer's or artist's established style. Either can be stopped at marketplace review or customs inspection, at a cost far above redrawing one image.
