Logo file requirements for promotional products: a practical guide that prevents rejections

What are the logo file requirements for promotional products?

Your last order stalled because the logo file you sent can’t be used in production. Here are the logo file requirements for promotional products that keep jobs moving through our Miami HQ art department without a redraw.

Send this, and it won’t get rejected: - A true vector file: .AI, .EPS, vector .PDF, or .SVG. Not a JPG/PNG/screenshot. - All fonts outlined to paths (no live type). If we don’t have your font, it will substitute. - Spot colors named as Pantone (PMS) swatches when color matters; don’t rely on RGB/CMYK names.

Vectors are built from paths, so they scale cleanly for lasers, screens, UV/pad print, and embroidery digitizing. We can take the same art from a 1" pen imprint to a 10" back print without stair-stepping edges. Rasters (JPG/PNG) are pixels. Enlarge them and you get blur or jagged edges, which a laser, screen, or digitizer will literally reproduce. Quick self-check: open your file and zoom way in. If edges stay razor-sharp, it’s vector. If you see squares, it’s raster.

Two more fast rules we enforce: expand strokes and effects before export (so line weights don’t change on another system), and embed/attach any linked elements. Then export your master once and use it for every order nationwide.

AI vs EPS vs SVG vs PDF: which logo file should I send to a promo shop?

Here’s the short, reliable rule we use daily: keep the .AI file as your editable master, and send .EPS or vector .PDF to outside decorators for the widest compatibility. That works because most screen print, laser, pad print, and embroidery shops can open EPS and PDF on any RIP or controller, and some older devices still only accept EPS. PDFs are fine too, but only if you save them with vector paths preserved (not flattened) and with spot colors intact.

Export each one so it survives production. The .AI stays internal: keep layers, name swatches by Pantone number, and leave a notes layer with minimum sizes — don’t send it unless the vendor specifically asks. For EPS, convert all text to outlines, expand strokes and effects, keep Pantone spots as spots, and save as Illustrator EPS (CMYK + Spot); EPS doesn’t support live transparency well, so expand appearances before saving. For PDF, use High Quality Print or Illustrator Default with “Convert Colors to Destination” turned off, spot colors left as spot, and vectors live; checking “Preserve Illustrator Editing Capabilities” keeps AI data embedded while the file still opens everywhere. SVG is useful for DTG/DTF and some digital workflows — outline the text, and because SVG doesn’t carry Pantone spots, put the PMS callouts on the spec sheet or many RIPs will interpret the colors as RGB.

What we actually send to vendors: one EPS and one vector PDF, plus the one-page color/size spec. For embroidery, they’ll digitize to a stitch file, but start with that same EPS/PDF.

How do I convert my logo to a true vector and set Pantone colors for fabric, thread, and metal?

If all you have is a JPG or PNG, we rebuild it clean in Illustrator. We place the raster at the largest available size, lock it, and redraw with the Pen tool. No Image Trace. We either set the exact fonts and outline them, or hand‑trace letterforms if the typeface is unknown so corners, bowls, and stroke terminals are consistent. We unite shapes with Pathfinder, expand strokes to fills, remove stray points, and balance curve handles so small embroidery and tiny pad prints don’t develop chatter on edges. Final check: everything is a fill, no live effects, no linked images.

Then we assign color by substrate, not one-size-fits-all. For ink on paper and most screen printing, we spec a Pantone Formula Guide Solid Coated or Uncoated spot color and make that a named Global swatch. For textiles, we proof on the actual fabric and either keep the PMS spot for ink mixing or specify the closest Pantone textile reference if your organization uses TCX/TPG. For embroidery, there is no true Pantone ink—so we list the nearest thread code by brand (e.g., Madeira classic/polyneon or Robison‑Anton) alongside the target PMS. For hard goods and metal, we set a PMS for pad/UV print; laser engraving is tonal only, so we note “no fill color.” In every export we preserve spot colors so those matches survive the RIP.

For South Florida and Latin America‑facing marks, we build bilingual lockups in one master .AI: separate, clearly labeled layers for EN and ES, same geometry and color, kerning adjusted for longer Spanish text and proper accents. Our Miami HQ art department keeps that master, and we ship vector EPS and PDF with the color/thread chart to any decorator nationwide.

What minimum logo size works for embroidery and laser engraving on small items?

Small embroidery and engraving eat thin strokes and tiny counters. Thread has a physical thickness and wants to bridge gaps; lasers bloom slightly on coated metal. Serifs, hairlines, and small holes in letters like A, e, and o are the first to disappear. Plan for it.

Here’s the floor we work to in the Miami HQ art department. For embroidery, keep the thinnest stroke at ~1 mm (about 0.04 in) and the smallest uppercase sans‑serif letters at 6 mm tall (about 0.24 in); lowercase or serif needs more, and negative spaces narrower than 1 mm will fill. For laser engraving on pens and small metal items, keep the thinnest stroke at ~0.2–0.25 mm and the smallest text at 1.5–1.8 mm tall, higher on powder‑coated surfaces. On a pen barrel, plan on at least 1.25 in of imprint width with those stroke and text limits.

Build a micro version of your logo for these cases: drop taglines and fine textures and run the wordmark or icon only, convert all type to outlines and expand strokes so everything is a solid shape, then open up the spacing between elements so nothing pinches below the limits above. Put those minimums on your one‑page spec sheet so vendors don’t guess.

Why does my logo color look different on shirts, mugs, and pens?

You’re asking different materials to behave like the same ink swatch. They don’t. Pantone actually publishes separate systems: the Formula Guide (ink on paper/plastic, “C” and “U” books) and Pantone Textile (fabric dyes, “TCX/TPG”). The same PMS name is not the same recipe across those books, so PMS 286C on a plastic bottle and the nearest TCX on a cotton tee will not render identically. On garments, ink sits in or on fibers; on hard goods, ink or glaze sits on a sealed surface; each reflects light differently.

Embroidery is another step removed. There’s no custom-mixed Pantone ink; we choose the closest pre-dyed thread from a chart (e.g., Madeira or Isacord). That’s an approximation, and small stitches make colors read darker. If you must prioritize, we’ll bias the match to how the logo is most often seen (caps vs tees).

Metal and powder-coated goods add reflectivity and texture. A matte powder coat will mute a color; gloss will pop it. Laser engraving isn’t printing at all—it reveals the substrate (raw aluminum, brass tone, black oxide), so your “color” is whatever the metal is. Metallics and fluorescents are unreliable everywhere: neons can’t be embroidered convincingly, and metallic inks rarely match a true anodized finish.

How we prevent shifts in our Miami HQ art department: we spec substrate-specific formulas up front (screen print PMS for cotton/poly, nearest thread codes for embroidery, factory coating/ink codes for hard goods), call out finish (matte/gloss), and require an underbase on dark polyester to block dye migration. Approve a physical swatch or a daylight-viewed pre-pro photo at 100% size; don’t judge color from a backlit PDF.

Is a high‑res PNG good enough? How to read and approve your virtual proof

No—a 3000×3000 PNG or crisp JPG is still raster. Engraving heads, screen separations, and embroidery digitizers need vector paths to plot clean edges and consistent line weight; pixels can’t tell a laser where to cut or a press where to hold a hairline. We’ll accept a PNG only for photo-based DTF/DTG; for marks and type, send AI/EPS/PDF with vector paths (fonts outlined).

One PMS number isn’t universal. In your proof, look for substrate-specific calls: ink PMS for screen print/pad print, the exact thread code and brand (e.g., Madeira color #____) for embroidery, and the metal finish or note for laser (tone-on-tone, no ink).

On the virtual proof, zoom to 100% and verify: finished size and placement (e.g., 3.25 in left chest, 1 in down from seam; 0.35 in barrel imprint on a pen), Pantone/thread IDs, fonts outlined so nothing reflows, and the correct English/Spanish lockup (accents, hyphenation, order). If anything’s unclear, ask our Miami HQ art department to annotate the proof before you sign; fixing it now beats re-running product.

FAQ

What files do promo product vendors actually accept?

Send a true vector: AI, EPS, vector PDF, or SVG. Outline all fonts, keep Pantone spot colors as named swatches, expand strokes and effects, and embed any linked elements. Rasters like JPG/PNG get rejected for print, laser, and embroidery. That setup opens on most vendor RIPs without a redraw.

Is a high-res PNG good enough for embroidery or laser engraving?

No. A high-res PNG or JPG is still raster, so engravers, screen printers, and embroidery digitizers cannot plot clean edges. Send vector AI, EPS, or vector PDF with fonts outlined; use PNG only for photo-based DTF/DTG printing. Vectors scale cleanly and survive RIPs without blur or jagged edges.

AI vs EPS vs PDF vs SVG - what should I send?

Keep the AI as your editable master. Send EPS or vector PDF to vendors because they open on nearly all RIPs and older devices. Outline fonts, expand strokes and effects, and preserve Pantone spot colors. If you send SVG, include PMS callouts on the spec sheet since SVG is RGB.

What is the minimum logo size for embroidery and laser engraving?

Embroidery needs about 1 mm minimum stroke (0.04 in) and 6 mm cap-height letters (0.24 in); tighter details fill in. For laser engraving on small metal items, keep strokes around 0.2-0.25 mm and text 1.5-1.8 mm tall, with larger limits on powder-coated surfaces. Build a simplified micro logo.

Why do my Pantone colors look different on shirts, mugs, and pens?

Different materials and Pantone systems render color differently. Paper and plastics use the Formula Guide (C/U), textiles use TCX/TPG, and embroidery matches pre-dyed thread, not ink. Lasers reveal substrate only. Prevent shifts by specifying substrate-specific formulas and approving a physical swatch or true-to-size daylight photo.

What should I check on a virtual proof before I approve it?

Confirm size and placement at 100% view, Pantone ink or exact thread codes by brand, and that all fonts are outlined so nothing reflows. Check the correct English or Spanish lockup with accents. Ask for annotations if anything is unclear; fixing proofs beats re-running finished product.
