How to Prepare All-Over Print Artwork: Seams, Bleed and Pattern Scale
A convincing mockup is a useful preview. A production file also has to survive cutting, sewing and the shape of the actual product. This guide turns that difference into a practical review.

Where should you start?
Start with the template for the exact product, keep essential details inside its designated safe areas and extend backgrounds through the specified bleed. Review every panel separately, then inspect a physical sample. Do not invent a universal margin or assume a perfectly tiled image will align across a sewn seam.
Confirm the material and production route
Snapwear’s AOP technology page describes fabric printing followed by cutting and sewing. Its cotton route uses roll-to-roll textile printing; its polyester route uses sublimation. AOP describes the coverage and construction concept, not one interchangeable recipe for every fibre.
Before opening a design file, record the product, material, available sizes and template version. If you replace the product, repeat the artwork review. A layout approved on one hoodie is not automatically approved on a sweatshirt with different sleeves, pockets or panel shapes.
Build an artwork record rather than relying on a filename such as “final-final”. A useful record links the product identity, source artwork, template, export, sample order and approval decision. This is an editorial workflow you can adapt; it is not a claim that every integration stores those fields for you.
Read three boundaries before placing a logo
| Boundary | Design action | Question to resolve |
|---|---|---|
| Visible cut or panel boundary | Understand which part becomes the finished panel. | Is the displayed outline a cut line, stitch line or preview boundary? |
| Bleed | Continue the background through the area required by the template. | How far does this product’s template require coverage? |
| Safe area | Keep essential content within the designated area. | Does the current template specify placement restrictions? |
If the template does not define an outline, ask for clarification. Do not import a margin from a different product or a general internet tutorial. Bleed is additional artwork coverage, not a guarantee that every edge or cross-seam detail will land at an exact coordinate.
A background should remain visually complete beyond the intended visible area. Essential text and faces need a different decision: they must remain readable if part of the composition is lost at a boundary. Review the background layer and the critical-detail layer separately.
Correct the composition, not just the export
Example A: a word split across a side seam. Extending the background will not fix the word’s dependence on precise panel alignment. Move the whole word onto one panel, or use separate complete words on each side. Review their positions on the worn sample.
Example B: a repeat with an obvious edge. Test the artwork as a two-by-two or larger tile arrangement in your design software. A hard border inside the tiled image is a repeat problem. A discontinuity where two garment panels meet is a construction question. Fixing one does not establish the other.
Example C: a face near a pocket edge. Treat the pocket and body as separate pieces until the template confirms otherwise. Move the focal element away from that interruption, or change the composition so the pocket does not need to complete the face.
These are design-review examples, not measured production failures. Snapwear’s AOP documentation explicitly warns that exact alignment across separately cut and sewn panels cannot always be guaranteed.
Check physical pattern scale and output resolution
A repeat described only as “20% scale” is difficult to reproduce after changing the document. Record its intended physical size where the template provides a physical reference. Inspect whether the motif looks appropriate on a sleeve, a large front panel and the smallest intended garment.
Calculation example, not an upload requirement: a raster panel 60 cm wide at 150 pixels per inch needs approximately 3,543 pixels across: 60 ÷ 2.54 × 150. At 300 pixels per inch the same width needs about 7,087 pixels. Changing a resolution label alone does not add original detail. Obtain the required output size and resolution from the product specification before exporting.
Keep the original artwork. Export a new production version for the selected template rather than repeatedly resaving an already resized image. Check text, fine features and the orientation of each sleeve or pocket at the intended output scale. Do not infer printable sharpness from a small storefront thumbnail.
Approve panels first, then the assembled product
| Review | Evidence to keep |
|---|---|
| Every printable panel is covered | An export or screenshot identifying each panel, including small pieces. |
| Background reaches the required bleed | The template layer and artwork can be compared. |
| Critical details avoid risky boundaries | A marked review showing text, logos and focal elements. |
| Pattern scale is intentional | The physical reference or scale setting is recorded. |
| The sample supports the intended offer | Full-product and detail photos, with observations and a decision. |
Inspect the sample both flat and in use. Note what was actually checked: readability, orientation, seam transitions and the appearance and feel of printed areas. Keep colour review separate from geometry; use the colour-matching guide for that part.
When a result is unexpected, preserve the submitted file and template before making a correction. Classify the issue: source image, export, placement, panel construction or product expectation. Send the relevant evidence through the supplier’s support process; this article does not define complaint eligibility.
Use the sample to complete the product page
Publish photos of the approved configuration and describe the garment accurately. Do not turn an illustration into a promise of continuous seam alignment. If you change the product, artwork scale, important placement or material, decide which checks and sample evidence must be repeated.
Start with one product from the catalogue, follow the sample approval workflow and keep the approved file linked to the store listing. For the material distinction, continue with the cotton AOP guide.
Frequently asked questions
Is AOP always sublimation?
No. Snapwear documents different cotton and polyester production routes. Confirm the material and process for the product you select.
What bleed size should I use?
Use the requirement of the exact product template. This guide does not establish a universal margin.
Does a seamless repeat guarantee matching garment seams?
No. A repeat can join within an artwork file while separately cut and sewn panels still have positional differences.
Is the pixel example a Snapwear specification?
No. It demonstrates unit conversion. Obtain the actual file dimensions and resolution requirement from the product specification.
