Artwork & file requirements

What ink and thread can and cannot do.

Everything below is what we would tell you before quoting a job. Print and embroidery want different things from a file — DTG and DTF are limited by resolution, thread by what a needle can resolve — so both are covered here. It is written so you can quote your own customer accurately, and so nobody finds out about a limitation at the proof stage.

Artwork for DTG printing

Prepare the artwork and garment together for direct-to-garment printing.

DTG prints directly onto the garment. Send your original vector file or a transparent PNG at 300 dpi at the final print size, with the intended placement and dimensions.

  • Include the garment style, fabric composition and color.
  • Remove unwanted backgrounds; do not enlarge a low-resolution screenshot.
  • Cotton and suitable cotton-rich garments are common choices. We review the exact fabric before confirming production.
  • Tell us your quantity and deadline so we can compare DTG with DTF for your project.

File formats we can work from

Vector first, raster at size, or a finished machine file — for print and for thread.

Three kinds of file arrive here, and they get treated differently. Vector artwork is redrawn as stitches for embroidery, or prepared for DTG or DTF printing. Raster artwork is traced first for thread, which introduces a judgement call, but prints directly if the resolution is there. A machine file is already stitches and goes straight to a sew-out.

FormatWhat it isSend it when
.ai / .epsAdobe Illustrator vector artworkAlways, if you have it. This is the ideal.
.pdfUsually vector, sometimes a wrapped imageFine — tell us whether the contents are vector.
.svgWeb vectorGood, provided paths are outlined.
.pngRaster with transparency300 dpi at final sewn size or better.
.jpgRaster, compressedAcceptable at 300 dpi; expect softer edges to be interpreted.
.dstTajima machine file — the trade standardYou already own a digitized design.
.embWilcom native design fileYou have the editable original and want it kept that way.

Why vector matters

A digitizer is deciding where every stitch begins and ends. With vector artwork those decisions follow paths you already drew. With a raster image the digitizer has to decide where an edge really is, and on a soft or compressed image that becomes an interpretation — a defensible one, but not yours.

  • Outline your type before sending. A font we do not have will substitute, and you will not see it happen.
  • Expand strokes rather than leaving them as live outlines.
  • Remove hidden layers, stray points and unused swatches — they slow the read and occasionally cause surprises.
  • A logo drawn at business-card scale still needs to be judged at the sewn size. Send it, then tell us the sewn size.

If all you have is a raster

Send the largest, cleanest version that exists — the original from your designer, not the one pulled off a website. 300 dpi at the finished sewn size is the working minimum. A 72 dpi web graphic enlarged to 4 inches gives the digitizer about a tenth of the information it looks like it has.

Artwork for DTF printing

Different medium, different rules — resolution and transparency do the work here.

Embroidery converts your artwork into stitches, so detail is limited by thread. DTF prints your artwork more or less as drawn, so detail is limited by resolution instead. That flips most of the advice on this page: color count stops mattering, gradients become free, and the things that will hurt you are low-resolution files and stray white backgrounds.

RequirementWhat we needWhy
Resolution300 dpi at final press sizeA 72 dpi web image scaled to a full back prints exactly as soft as it looks on screen.
BackgroundGenuine transparency (PNG or vector)Anything white in the file prints white — including a background you assumed was empty.
Color spacesRGBFiles land in sRGB anyway. Sending CMYK just means we convert it and you do not see the shift.
Line weight1 pt minimum, 1.5 pt on dark garmentsHairlines break up on the press and can lift in the wash.
Text size6 pt minimumSmaller resolves on film but closes up once it is pressed into fabric.
File typesAI, EPS, PDF, SVG, or 300 dpi PNGVector is still ideal because it scales without any decision from us.

What DTF does better than embroidery

  • Unlimited colors at no extra cost. A photograph prices the same as a one-color logo.
  • Gradients, drop shadows and soft edges reproduce properly instead of being interpreted into thread.
  • Fine detail and small text survive, because nothing has to be weeded or stitched.
  • Single pieces are economic. There is no screen to make and no setup to amortise.
  • One transfer presses across cotton, poly, blends and performance fabric in the same order.

What still belongs in thread

  • Anything where perceived value matters — corporate left chest, polos, outerwear, headwear.
  • Garments that see hard service and industrial laundering.
  • Caps, where a press cannot reach the seam and the curve the way a cap frame can.
  • Fleece and heavy texture, where a print sits on the pile rather than in it.

Gang sheets

Multiple designs nest onto one film sheet and you are charged for the area used rather than per transfer. If you are sending twenty small logos, send them as one job and let us nest them — it is materially cheaper than twenty separate transfers, and it is the single easiest saving on a mixed order.

What sews well, and what does not (embroidery)

Thread has a minimum size. Some artwork simply cannot get there.

Thread is roughly a fixed diameter. Everything below is a consequence of that one fact: a stitched mark cannot be finer than the thread making it, no matter what the artwork does.

Sews cleanly

  • Solid shapes with clear separation between elements
  • Bold, geometric lettering at reasonable size
  • Flat spot colors with hard edges
  • Simple outlines with consistent stroke weight
  • Marks that still read when printed in one color at final size

Fights the medium

  • Text below about a quarter inch cap height — the counters in letters like a, e and s fill in.
  • Hairlines and strokes below roughly 1 mm at final size — thread cannot hold them.
  • Gradients and drop shadows — thread is flat. These become bands of solid color or get dropped.
  • Photographic detail and soft focus — there is nothing for a stitch to follow.
  • Very fine serifs, script with thin connectors, and delicate flourishes at small sizes.
  • Ten colors in a two-inch logo — every color change is a stop, a trim and a chance to register imperfectly.

None of this means the job cannot be done. It means the artwork usually needs a stitch version: slightly bolder, slightly simpler, with the elements that will not survive removed rather than attempted. We will tell you what we would change before we digitize, not after you have seen the sew-out.

Rules of thumb

LIMITS
Smallest text
About 1/4 inch cap height for block lettering
Thinnest line
About 1 mm at finished size
Color count
Fewer is faster, cleaner and cheaper
Test
Print it in one color at final size. Still readable?

Stitch count, price and production time

The unit of currency in contract embroidery.

Embroidery is priced and scheduled on stitch count, not on how complicated the artwork looks. A design is a number of needle penetrations, and that number sets both what a run costs and how long a machine is occupied.

What drives the count: the area being covered, the density needed for the fabric, the amount of underlay laid down first, and the number of separate elements that have to be tied off and traveled between. Size is the biggest lever — a design taken from 3 inches to 4 inches wide does not gain a third more stitches, it gains closer to three quarters more, because area grows with the square.

What this means when you are quoting your own customer

  • Ask for the stitch count with the sew-out. It is the number that lets you compare quotes honestly.
  • A cleaner digitizing job can take thousands of stitches out of a design that reads identically. That is the difference between digitizers, and it compounds across every piece you ever run.
  • Dropping a design from 4 inches to 3.5 inches often saves more than it costs in visual impact.
  • Full-back and jacket-back designs run long. Build that into your lead time, not just your price.

Placements and finished sizes

Where it goes, and how big it should be when it gets there.

Give us the finished sewn width for each placement. It is the single most useful number on a quote request, and it is the one most often missing.

PlacementTypical finished widthNotes
Left chest3 to 4 inThe workhorse. Center roughly 7–9 in down from the shoulder seam.
Full front9 to 11 inWatch placket and button interference on polos.
Full back10 to 12 inLong run times. Often better in twill appliqué.
Sleeve2.5 to 3.5 inConstrained by the sleeve circumference and any hem.
Cap front2 to 2.5 in tallDigitized separately from flats. Seam and crown height rule.
Cap side / back1.5 to 2.5 inSmall area, so keep detail minimal.
Collar / cuff0.5 to 1 inMonogram territory. Text only, kept simple.
Bag panelVariesCheck for pockets, seams and linings before committing.

Sizes above are the ranges most jobs land in, not house rules — a brand standard beats a rule of thumb every time. Send yours and we will work to it.

Fabric, backing and stabiliser

The choice nobody sees, and the one that ruins a run when it is wrong.

Backing holds the fabric still while thousands of needle penetrations try to move it. Choose it wrong and the design puckers, the registration drifts, or the backing shows through a light knit forever.

FabricUsual backingWatch for
Woven shirting, twillLight to medium cutaway or tearawayStable already; over-backing stiffens the garment.
Piqué and jersey knitsMedium cutawayStretch. Tearaway on a knit is how puckering starts.
Performance / moisture-wickingCutaway, lighter density designNeedle damage and grin-through. Density has to come down.
Fleece and sweatshirtMedium cutaway plus a water-soluble toppingStitches sinking into the pile without a topping.
Towelling and terryCutaway plus toppingLoops pushing through the fill.
Structured capsCap backingSeam, crown height and the buckram behind the front panel.
Waterproof / coatedReconsider stitchingEvery penetration is a hole. Heat-seal may be the right answer.

Tell us the garment — style number and color — on the quote request. It changes the digitizing, not just the setup, and a design digitized for an oxford will bury a lightweight performance knit.

Caps are a different job

Same logo, different file.

A cap sews from the center out, on a curved surface, through a stiffened panel, in a fixed vertical space between the brim and the crown seam. A design digitized for a flat left chest will not simply scale onto it.

  • Sequencing is different: cap designs are built center-out so the fabric does not push ahead of the needle.
  • Vertical space is limited by the crown height — usually a little over 2 inches on a structured cap.
  • Detail that survives at 3.5 inches on a chest often has to be simplified at 2.25 inches on a cap front.
  • Unstructured crowns behave differently from structured ones, so tell us which you are running.

If a program runs both flats and caps, plan for two digitized files from the start. It is not an upcharge for its own sake; it is the only way both come out right.

Color matching and thread

Thread is a stocked shade, not a mixed ink.

Print color is mixed to a target. Thread color is chosen from what exists on the shelf. We match to the nearest available shade and, where a brand standard is tight, we will send the sew-out with alternatives so you can choose rather than be told.

  • Send Pantone references where color is contractual. "Their blue" is not a specification.
  • Thread reads differently from ink — the sheen of rayon and the matte of polyester will not look identical to a printed swatch.
  • A color that works on white will read differently on navy. The garment color is part of the match.
  • Polyester thread is the right choice for anything that will be industrially laundered or bleached.
  • Fewer colors means fewer trims, less travel and a cleaner finish. It is worth an honest look at whether a five-color logo needs all five in thread.
