Contour Cut Files Explained: CutContour, Spot Colors, and Print-and-Cut

Some of the best-margin work in a wrap shop isn't wraps at all — it's decals, die-cut lettering, and print-and-cut graphics. All of it depends on one file convention that nobody formally teaches: the contour cut path. Get it right and the plotter traces your shapes perfectly through a laminated print; get it wrong and someone hand-weeds a ruined sheet. (This is a sibling to the bleed, seams, and panel layout guide — that one preps full wrap panels, this one preps everything that gets cut to shape.)

What Print-and-Cut Actually Is

Print-and-cut is the two-machine workflow behind every custom decal: a printer lays down the graphics, the print gets laminated, and then a cutting plotter traces an outline around each shape. Two cut depths exist:

• •Kiss cut — through the vinyl and adhesive but not the liner, so decals peel off a backing sheet
• •Through cut (perf cut) — all the way through the liner, separating pieces entirely

The plotter needs to know exactly where to cut, and that information travels inside your print file as a specially marked path. That's the contour cut line.

The CutContour Convention

The industry convention, supported by every major RIP, works like this:

• •Create a spot color swatch in your design app — color type Spot, not Process
• •Name it exactly CutContour — one word, capital C twice
• •By convention, define it as 100% magenta so humans can see it on screen
• •Apply it as a stroke to the path you want cut
• •Set that stroke to overprint, so it doesn't knock a white gap out of the printed art beneath it

When the file hits the RIP, the software searches for a spot color with that name, strips it out of the print data, and routes it to the cutter as a cut path. The printed output shows no magenta line at all — the path was never really a graphic, it was an instruction.

Why the Name Matters More Than the Color

This is the part that bites newcomers: the RIP matches the swatch by its name string, not its appearance. A path that looks identical on screen but uses process magenta, or a spot swatch named "Cut Contour" with a space, or "cutcontour" in lowercase, is just a printed pink line on your customer's decals. Many RIPs are case-sensitive about it, so the safe habit is treating the name as sacred: CutContour, exactly.

The magenta is purely for humans. You could define the swatch as any color and the RIP wouldn't care — magenta is the convention because it's visible against most artwork.

Some workflows use more than one named path. Roland's VersaWorks convention, for example, adds PerfCutContour for through-cuts alongside CutContour for kiss cuts, letting one file carry both cut depths. Check what the destination RIP expects before inventing your own names.

What the RIP and Plotter Do With It

Understanding the machine side makes the file rules make sense:

• •The RIP separates the CutContour spot into a cut job and prints registration marks around the graphics
• •The print gets laminated — which is why the cut happens as a second pass, after lamination
• •The plotter's optical sensor reads the registration marks, aligning the cut file to the physical print even if the media shifted or skewed slightly
• •The blade then traces your path — every node, every curve, exactly as drawn

That last point is the quiet killer: the plotter honors your path literally. A messy path with hundreds of stray nodes cuts slowly and raggedly. Clean geometry cuts clean.

Building the File: The Working Rules

• •Put the cut path on its own layer, above the artwork
• •Keep it a simple, closed path — the fewer nodes the better
• •Offset the cut line from critical art: leave roughly 2–3mm of printed bleed beyond the cut line, and keep important graphics at least that far inside it, so slight registration drift never shows white or clips the art
• •For lettering, cut around the whole word or a containing shape when you can — cutting every letterform individually turns weeding into an afternoon
• •Export in a format that preserves spot colors — PDF or EPS — and confirm the swatch survived by checking separations before sending

The Classic Failures

Every one of these produces a job that looks right on screen and fails at the plotter:

• •Process magenta instead of spot. The line prints; nothing cuts.
• •Wrong name or wrong case. Same result — the RIP is looking for one exact string.
• •Outlined text as the cut path. Tiny counters and serifs become hundreds of micro-cuts and an unweedable sheet.
• •Expanded strokes. A stroke expanded into a filled shape becomes two parallel paths — the plotter cuts twice, a blade-width apart.
• •Open paths. The cut never closes, and the decal doesn't release cleanly.
• •Overprint forgotten. The cut line knocks a white halo out of the printed art beneath it.
• •Live effects on the cut path. Path effects that were never expanded can rasterize or drop in export — what the RIP receives isn't what you saw.

A 60-Second Preflight

Before any print-and-cut file leaves your machine: open separations preview and confirm CutContour shows as its own plate; confirm the path is closed, stroked (not filled), and set to overprint; check the offset between cut and art; and zoom the path at high magnification looking for stray nodes. One minute of preflight against hours of weeding is the best trade in the shop.

Cut files are a small craft with an outsized reputation payoff — the designer whose decals cut perfectly the first time is the designer the production manager requests by name.
