Press-Ready Vectors for Screen Printing
One color, one screen, one film — that's the physics of the press, and it's why the 400-pixel JPG your customer just emailed can't go to the darkroom. VectoSolve traces it into flat, solid color regions you can pull separations from, and hands them back as EPS, SVG, PDF and PNG — without redrawing it in Illustrator.
The file is always wrong. The press doesn't care.
You know the routine. The "logo" arrives as a 72-dpi image lifted off the customer's website, a phone photo of a business card shot under office lighting, or a screenshot of a shirt you printed for them in 2019. They'll swear it's their vector file. It never is.
Meanwhile the press has non-negotiable requirements: every ink gets burned onto its own screen from its own film positive, and that film needs artwork that resolves into flat, cleanly bounded color regions. Raster art fails on both counts — its edges are anti-aliased into hundreds of in-between pixel shades, and its "colors" are compression noise, not regions. There is no mesh count that fixes a bad file.
The standard workarounds are the art fee — commonly $15–40 per job to redraw the logo, which costs you 30–90 minutes at the pen tool — or shipping the file to an overnight vector service and losing a day on the turnaround. VectoSolve is the third option: the redraw happens in seconds, the separation still happens in your own software on your own terms, and the art fee stays yours to bill.
What "screen-ready" actually means in a vector
Not every SVG is separable. These are the properties that decide whether the file seps in one click or eats your evening — and they're what VectoSolve's tracing and post-processing are tuned for.
Flat, solid fills
No gradients, no blends. A gradient can't sit on a screen as-is — it has to become a halftone of one ink downstream. Spot art should be flat color, and that's exactly what the tracer outputs.
Few colors, real regions
Every color you keep is a screen you'll coat, expose, register, and reclaim. Color merging collapses near-duplicate shades into single fills so your palette matches your ink count, not JPG noise.
No anti-alias fringe
The soft pixel haze around raster edges turns into dozens of phantom "colors" the moment you try to separate. Vector shapes have a hard boundary — the fringe simply doesn't exist.
Closed, selectable shapes
Each region is a filled path, so "select same fill" in Illustrator or Corel grabs an entire ink in one click. That's what makes a one-click sep possible instead of an evening of cleanup.
Under the hood, every conversion runs a cleanup pass that merges near-duplicate shades into single flat colors and deletes stray speckles — the two raster artifacts that most often pollute a separation.
From phone photo to film positive
Clean the source
Strip the desk, the letterhead, or the shirt fabric out of a phone shot with background removal. If it's a tiny web logo, upscale it first so the tracer has real edges to find.
Vectorize
AI traces the image into flat color regions, merges the palette, removes speckles, and hands back one ZIP with the same artwork as EPS, SVG, PDF, and PNG.
Pull the seps
Open it in Illustrator, CorelDRAW, or your separation software. Select by fill to put each ink on its own layer, assign Pantones, add trap, choke, and underbase where the job calls for them.
Output film & burn
RIP each separation to a solid, opaque black positive — grey doesn't block UV — then expose, register on press, and print.
Mesh, line weight & halftones: check the numbers before you output film
None of this happens inside VectoSolve — it happens in your sep software and your darkroom — but it decides whether the vector you make here prints clean, so sanity-check your detail against it.
The halftone rule of thumb: maximum LPI is roughly your mesh count divided by 4.5 to 5. That's why a 156 screen tops out in the low 30s LPI while a 305 can carry the 60s. If a design leans on tints or gradients, that math — not the artwork — sets how fine the dots can be.
Minimum detail: keep positive strokes at about 1 pt (0.35 mm) and text at 8 pt or larger at final print size. Reverse (knocked-out) detail needs to be heavier, because plastisol bridges thin gaps in the stencil. If a converted logo has hairlines below that, thicken them in your design software before film — no press setting rescues a stroke the mesh can't hold.
Dark garments: plan an underbase — white printed first, flash-cured, colors on top — and choke the base slightly so it never peeks past the top colors. Between adjacent inks, a small trap absorbs the registration drift every manual press has. Both are separation-software moves, made possible by art with clean region boundaries.
Spot, process, or simulated: which jobs to vectorize
Honest answer: not every job should go through a vectorizer. Here's the split.
Spot color
One to six mixed inks, usually Pantone-matched, printed solid or as tints of themselves. Logos, text, mascots, event shirts — the bulk of what walks into a shop, and exactly what image-to-vector conversion is built for.
CMYK process
Four transparent inks halftoned over white or light garments, built from high-resolution raster art in your RIP. Don't vectorize a photo for this — keep it raster, and upscale it if the source is small.
Simulated process
Six to ten opaque inks halftoned to fake photorealism on dark shirts, built by a separator from high-res raster art. Same advice: this workflow stays raster from start to film.

FAQ
Why does screen printing need vector art?▼
Because every ink color goes on press as its own screen, burned from its own film positive. To output those films you need artwork that resolves into flat, cleanly bounded color regions. A JPG logo fails at exactly that: its edges are anti-aliased into hundreds of in-between pixel shades that no separation can cleanly assign to one ink. A vector defines each region as a filled shape with a hard edge, so every ink pulls out as a solid, sharp film at any print size.
Does VectoSolve do the color separations and halftones?▼
No, and we won't pretend it does. VectoSolve converts raster images into clean vector art with flat, merged colors — the step before separation. You pull the actual seps in Illustrator, CorelDRAW, or dedicated software like Separation Studio or AccuRIP, which is also where halftones, underbase, choke, and trapping happen. What VectoSolve fixes is the part that usually eats your time: getting from the file the customer sent to art those tools can actually separate.
What do shops usually charge to vectorize customer art?▼
A vectorization or "art fee" of roughly $15–40 per job is common industry practice, and overnight vector services charge per file and cost you a day of turnaround. Nothing about using VectoSolve changes what you bill — it changes how long the redraw takes. A conversion runs in well under a minute instead of 30–90 minutes of pen-tool work.
How many colors should my design have for screen printing?▼
Most spot-color jobs run 1 to 6 inks. Every color you keep is another screen to coat, expose, register, and reclaim, so fewer is cheaper and faster. VectoSolve's post-processing merges near-duplicate shades into single flat fills, so a 4-color logo comes out as 4 usable regions instead of 40 slightly-different ones — but the final call on the ink count is yours, made in your separation software.
What about gradients and photorealistic designs?▼
Screens can't print continuous tone — a gradient has to become a halftone, a pattern of dots in one ink. Photorealistic jobs on dark garments are usually run as simulated process: 6–10 opaque inks halftoned from high-resolution raster art by a separator. Don't vectorize a photo for those jobs; keep it raster (upscale it if the source is small). Vectorization is for the spot-color work — logos, text, mascots, flat illustration — which is most of what walks into a shop.
How small can lines and text be on a screen print?▼
On typical garment mesh, keep positive strokes at roughly 1 pt (about 0.35 mm) or heavier and text at about 8 pt and up at final print size. Knocked-out (reverse) detail needs to be bigger still, because plastisol likes to bridge thin gaps in the stencil. If the job genuinely needs finer detail, that's a higher mesh count decision — 230 and up — not something any file format can fix on 110 mesh.
Which file formats can I export for my separation software?▼
Downloading on this page gives one ZIP holding the same artwork four ways: EPS, SVG, PDF, and PNG. Paying by card sends the EPS itself to your download link. EPS is the safe handoff for CorelDRAW and Illustrator separation workflows, PDF opens anywhere, the SVG covers newer tools, and the PNG is there for the approval email. All exports carry commercial-use rights, so files you prep for customer jobs are covered.
Shop owners: would automatic spot-color separations help?
We are weighing a tool that takes the vector you just made and outputs one print-ready film per ink color, registration marks included. It does not exist yet, and we only build what real shops ask for.
Yes, I would use that — tell us how you separate todayOr write to contact@vectosolve.com with the word separations.

If screen printing is your business, you are probably paying per file.
An outside art service charges 6 to 26 dollars a logo and comes back the next day. Redrawing it yourself costs half an hour you could bill. A year here is $49 for 25 conversions every month, every machine format included, which works out cheaper than two outsourced logos.
