Screen Printing the in270 Mark? Don't Send Your Printer the Vinyl File

What file do you need to screen print a logo?

A flattened, limited-color vector file, separated by ink layer, one file per screen. That is the short answer, and it is not the same file you used to cut vinyl for a storefront window. Most of the registration problems and muddy prints we hear about from shops around the loop come down to one mix-up: somebody handed the screen printer the wrong format, and the printer either burned a bad screen or guessed.

If you requested the free window cling or downloaded the in270 kit and you're now walking into a print shop with a fall craft fair table or a game-day merch run to fill, this is the thing to get right before you place the order, not after the first batch comes back blotchy.

Vinyl file versus screen print file: what's actually different

A vinyl cutter wants one thing: a clean, closed cut path it can trace with a blade, no fills, no gradients, nothing to interpret. That's the mono SVG in the in270 kit. One color, one outline, ready to weed.

A screen printer wants something else entirely. Screen printing pushes ink through a mesh screen, one screen per color, and each screen needs its own file: a flattened shape with hard edges and no color blending, because a screen can't print a gradient any more than a rubber stamp can. If you're printing the mark in one ink color, that's the mono file again, same as vinyl, which is where some shops assume one file does both jobs. It mostly does, until you want a second color.

Want the loop in brick and the interior roads (71, 70, 670, 315) in a second ink? Now you need a two-color separation: two files, each one a single flat shape showing only what that screen should print, with the rest transparent. Hand a screen printer a full-color PNG instead, the kind meant for a sticker or a webpage, and you're asking them to either guess at a separation themselves or print something flat and dull from a format that was never built for ink layers in the first place.

We've written about the vinyl side of this in more detail if that's the job in front of you: why the in270 mark chokes vinyl cutters and how to cut the mark in vinyl both walk through the cutter-specific problems, which are different from the screen printing ones.

What's in the in270 kit, and which piece goes where

The kit runs from 32 to 2048 pixels, in both SVG and PNG, in color and mono, plus the Confluence and Broad and High secondary marks if your project calls for one of those instead of the loop.

Here's the plain mapping:

Vinyl cutter: mono SVG. Clean path, one color, scalable to whatever size the job needs.

Screen printer, one color: mono SVG, same file, flattened and sized for the screen.

Screen printer, two colors: a separated vector file showing the loop and the interior roads as distinct layers, each one its own screen.

Embroidery: a different conversation. Digitizing for thread is its own process with its own file type (a stitch file, not a vector), and it deserves its own explanation rather than a rushed paragraph here. We'll cover it properly later.

If you're not sure which combination your file falls into once you've opened the kit, the small-size rule and do-nots on the guidelines page spell out minimum sizing and what never changes about the mark, which matters just as much for a screen as it does for a window cling.

The one rule that doesn't bend, even for a screen that's hard to burn

The geometry is traced from OpenStreetMap data under the Open Database License. The east bulge toward the airport, the flat north side, the Grove City hook: that's the real road, not a shape somebody drew to look nice on a shirt. We've covered why the loop isn't a circle and why 270 bends near Grove City if you want the full story behind those specific curves.

Some screen printers will ask to simplify the path to make a screen easier to burn, or to clean up a tight curve so it's less likely to clog during printing. That request is reasonable from a production standpoint and wrong for this mark. Smoothing the bulge, squaring off the hook, rounding the curves out, any of that changes the actual shape of the loop, and the license doesn't allow it. The answer is no, and the fix is not to redraw the file, it's to print at a size where the detail holds. That's exactly what the kit's size range is for.

What to say when you call your screen printer

Keep it short. Tell them: "I have a one-color mark, here's the mono SVG, flatten it to one screen, don't adjust the path." If you're going two colors: "Here are two separated vector files, one screen each, loop and interior roads, keep the geometry as-is."

Send the file ahead of the call if you can. A printer who sees the actual vector before quoting the job will catch a mismatch (wrong color mode, wrong file type) before it costs you a reprint during a season when print shops are already backed up with fall orders.

If you just want it in a window, skip all of this

None of the above applies if you're a shop inside the loop and you just want the mark in a street-facing window, not on merchandise. That's the free window cling program: request it, and we bring it by. No file wrangling, no screens, no separations. Save the vector conversation for the day you actually run shirts or totes.

If that's you, head to the free window cling request instead and skip the rest of this page entirely.

If you're printing merch, download the correct file from the mark kit before you call your screen printer, and check the guidelines page first so nobody on the shop floor rounds off the geometry to save a step.
