Why It Matters
Specs are not a gate — they cut rework
Printing is "produce to artwork" — the clarity and printability of the file decide whether the first piece passes and whether color is accurate. Ten minutes against this list saves most back-and-forth. No file is fine too — we can help redraw or vectorize.
General requirements
| Item | Requirement | Notes |
|---|---|---|
| Resolution | ≥ 300 dpi | Bitmaps below this blur and jag when enlarged; vector files have no such limit. |
| Color mode | CMYK / spot | Screen work is more accurate with PANTONE spot or CMYK; digital (DTG / DTF) accepts RGB or CMYK, using on-screen color as reference. |
| File format | AI / CDR / PDF | Prefer vector (text outlined or fonts embedded); a hi-res PNG (transparent) beats JPG for bitmaps. |
| Bleed & placement | 3mm bleed for full print | Full-bleed patterns need bleed; for placed art, mark print position and size to avoid trimming disputes. |
| Text handling | Outline / embed | Outline or embed fonts to avoid substitution; very small screen text (< 2mm) is hard to keep crisp — enlarge it. |
| Printable area | ≥ 1.5cm from seams | Avoid zips, cuffs, seams and pronounced curves; for irregular parts confirm the printable / heat-pressable face first. |
| Risky / sample | Ultra-fine gradients, curves | Metal, glass and curved parts: sample to verify adhesion first; avoid steep curves (> 30°). |
Per-process notes
Screen printing
Fewer colors cost less — ≤ 6 advised; gradients need halftone, solid blocks are best.
DTG
Best on light cotton; dark needs a white underbase; not suited to large thick-white or high-stretch fabrics.
DTF
Any base color and fabric; full print, gradients and photo-real all OK; leaves a slight film hand-feel.
UV / crystal label
Best on flat hard parts (acrylic, metal, glass); avoid big curves, run an adhesion test first.
No Artwork
A reference image is enough
Not having an editable vector file is common. Send a reference image, a photo of the physical item or a hand sketch — we help redraw, vectorize or sample to confirm, then go to bulk. Design support carries no extra charge; it is included in the quote.
Send via WeChat (recommended)
Same number as phone 15153909200 — send originals and placement refs for the fastest response.

In the RFQ choose "artwork status"; a clear description can also get a first estimate.
