An oversized original does not survive being photographed. Point a camera at a stretched canvas and you capture the lens distortion, the uneven light across the surface and the glare off the varnish — then you enlarge all three. Lay a rolled set of building plans on a desk and the creases become shadows. Large format scanning exists for exactly this problem: it captures an original too big for a desktop scanner at a resolution that still holds up when the file is printed at ten feet.
This guide covers what large format scanning is, what fits in a single pass and what has to be stitched, the three materials a scan gets printed on, and how to get an original to the scanner and back if you are not local. Color Reflections runs high-resolution scanning out of its Hollywood, Florida location, and every specification below comes from that service.
Key takeaways
- Originals up to 4 by 6 feet are scanned in a single pass. Anything larger is scanned in multiple passes and stitched together.
- A scan can be printed back at its original size or as large as 10 feet or more, so set the output size before the scan, not after.
- Variable lighting does two opposite jobs: it can eliminate shadows on a flat original, or hold the relief of a textured one such as an oil painting or a topographic map. Say which you want.
- Scans print on textured poly/cotton canvas, acid-free cotton and alpha cellulose fine art paper, or resin-coated photo paper in glossy, matte or luster.
- You can ship the original by FedEx or UPS from anywhere. It is repackaged and returned, and the finished scan comes back on a USB drive or as a Dropbox link.
What large format scanning actually is
Large format scanning is the capture of an original that is physically too large for office equipment, at a resolution and color accuracy meant for reproduction rather than reference. The distinction matters. A reference scan only has to be legible. A reproduction scan has to carry every line, hue and brushstroke of the original, because the whole point is that someone will print it again — often much bigger than it started.
Color Reflections describes its process as calibrated to preserve that detail, and frames the work as preserving the integrity of the original rather than simply digitizing it. In practice that means the finished file is built to be printed back at anything from the original size up to 10 feet or more.
That range is the useful part. The same scan of a 30 by 40 inch painting can produce a matching fine art print, a conference room panel, or a wall-height graphic, without going back to the artwork a second time.
What fits in a single pass, and what gets stitched
The Hollywood scanner captures originals up to 4 by 6 feet in one pass. Larger originals are scanned in multiple passes and the sections are stitched together.
Single-pass capture is worth planning around. One pass means one lighting condition and one geometry across the whole surface, so there is no seam to align and no risk of a tonal step where two captures meet. Stitching is routine work and it is how anything over 4 by 6 feet gets done, but it is additional handling, and it is a reason to know your measurements before you call.
Measure the original itself, including any border or mount you need captured. A 36 by 48 inch architectural sheet sits comfortably inside the single-pass window. A 5 by 8 foot canvas does not, so expect it to be scanned in sections and stitched.
Scanning capacity, in five numbers
What the Hollywood scanning service will take on
Size limits, output range, the kinds of original accepted and the print materials offered — the four things that decide whether your piece is a routine job or needs a conversation first.

The nine kinds of original this is built for
The service is not only for art. The list of originals accepted splits into three working groups, and each one wants something different from the scan.
Art and photography. Artwork and artist renderings, and photographs. Here the job is color fidelity and surface character — the reproduction has to read as the piece, not as a picture of the piece.
Technical drawings. Blueprints, building plans, engineering drawings, schematics and manufactured product designs. Here the job is line integrity at scale. A hairline on a drawing has to stay a hairline when the sheet is reprinted, and faint pencil or blueprint tones have to separate from the paper.
Cartography. Cartographic maps and topographic maps. These combine both problems: dense fine type and, on a relief map, real physical texture.
Color Reflections names the end uses as professional presentations, advertising or marketing, museum displays and personal use. Those four have very different tolerances, which is why the output size question below comes first rather than last.
Variable lighting is what separates a scan from a photograph
The scanner’s lighting is variable, and that capability does two opposite jobs depending on what you ask for. It can eliminate shadows, or it can produce a true three-dimensional image when the original is textured — Color Reflections gives topographic maps and textured oil paintings as the examples.
Those are genuinely different outcomes and you have to choose.
For a creased blueprint, a rolled map or a canvas with a slight warp, you want shadows gone. Any raking light turns a crease into a dark line that will be printed as though it were part of the drawing, and removing it afterward is retouching work that should never have been necessary.
For an impasto oil painting, a letterpress proof or a relief map, you want the opposite. The brushstroke relief and the paper bite are part of what the piece is. Flatten them and the reproduction looks like a poster of the painting. Hold them and it reads as the object.
Say which one you are after when you book the scan. It is a two-word instruction that changes the result, and it is the single most common thing left out of a brief.
Three print materials, and where each one fits
A scan is a file, but most people are buying a print. Color Reflections stocks three materials for scan reproductions and describes each one in terms of what it does to the image.
| Material | What the material does | Where it fits |
|---|---|---|
| Textured poly/cotton canvas | A texture that enhances image quality while minimizing pixelation, with strength, flexibility and color vibrancy | Painting reproductions and large wall pieces, where the surface should not read as flat paper |
| Acid-free cotton and alpha cellulose fine art paper | Cotton for color richness and alpha cellulose for structural integrity, at a weight built for durability | Editions, archival work and anything that will be matted, framed or kept |
| Resin-coated photo paper | Maximum ink coverage and a high D-max, producing true photographic reproductions; glossy, matte or luster | Portraiture, landscape photography and scanned photographic originals |
The finish choice on resin-coated paper is not cosmetic. Glossy gives the deepest blacks and the most glare, which is a problem under downlights. Luster and matte give up a little depth and become readable in a lit room. If the print is going somewhere with ceiling spots above it, ask for the matte or luster version.
Getting the original to Hollywood and back
Scanning is one of the few print services where the thing being bought has to physically travel, and that is the part people hesitate over. The arrangement is straightforward.
Originals are accepted from anywhere by FedEx or UPS. After scanning, the piece is repackaged and returned to you. If you are nearby, you can drop it off at the Hollywood shop at 2960 Stirling Rd, Hollywood, FL 33020. Either way, you hear back within 24 hours to coordinate how the piece gets there.
The finished scan is delivered on a USB drive or as a Dropbox link you download. Dropbox is also the file route the Hollywood location uses for incoming large files, so if you have supporting artwork or a reference file to send, that path is already set up — see the file upload page for the per-location routes.
What to settle before the scan, not after
Five decisions, in the order they matter. Settle them on the first call and the scan gets done once.
- The largest print you will ever make from this file. Name a number. The scan is captured for an output range that runs from original size up to 10 feet or more, and the resolution decision follows the top of that range, not the first print you happen to need.
- Shadow or texture. The variable-lighting choice described above. Flat and shadow-free for drawings and creased originals; three-dimensional for textured paintings and relief maps.
- Whether the original leaves the frame. Decide who removes a canvas from its stretcher or a drawing from its mount, and whether it goes back the way it came. This is a conversation, not an assumption.
- Color references for anything that must match. Color Reflections’ own file guidance notes that printers work in CMYK and that Pantone references give the most accurate color match. If a logo color or a brand hue has to be right on the reproduction, hand over the Pantone reference rather than describing the color.
- How you want the file delivered. USB drive or Dropbox link. Say it at the start and it is ready when the piece is.
Where a large format scan usually ends up
Most scans are not the finished product. They are the source file for something printed much larger, and the sensible move is to decide the destination before the scan so it is captured once at the right size.
Scanned art most often goes to an interior graphic. A painting or rendering captured at this resolution can be printed as a custom wall wrap covering a lobby or corridor wall, or built into a wider environmental graphics program across a floor so the art, the room identification and the wayfinding read as one scheme.
Technical drawings and maps tend to go the other direction, onto display panels and presentation boards. Those need mounting, framing or a built structure, which is custom fabrication work rather than print work, and it is worth raising while the scan is still being specified.
Anything going very large sits with large format printing, where the press size rather than the file is usually the constraint. If you are new to specifying print at that scale, the complete guide to large format printing covers the materials and the production side.
Frequently asked questions
How large an original can be scanned in one pass?
Up to 4 by 6 feet. Larger originals are scanned in multiple passes and the sections are stitched together.
How big can a large format scan be printed?
From the original size up to 10 feet or more. Set the largest size you expect to need before the scan is taken, because that is what the capture is built around.
Can I ship my original instead of bringing it in?
Yes. Originals are accepted by FedEx or UPS from wherever you are, and they are repackaged and returned after scanning.
How do I receive the digital file?
On a USB drive, or as a Dropbox link you download.
What can be scanned besides artwork?
Artist renderings, photographs, blueprints, building plans, engineering drawings, schematics, manufactured product designs, cartographic maps and topographic maps.
Will a scan keep the texture of an oil painting?
It can. The scanner’s variable lighting can produce a true three-dimensional image when the original is textured, and textured oil paintings are one of the examples given for that. Ask for it, because the same lighting can also be set to remove shadow entirely.
Which Color Reflections location does the scanning?
Hollywood, Florida, at 2960 Stirling Rd, Hollywood, FL 33020.
Plan a large format scan
If you have an oversized original and a wall, a presentation or an edition in mind for it, the useful first step is to name the biggest print you want from it. Everything else in the scan follows from that one number.
Start with the high-resolution scanning service, or go straight to the Hollywood, Florida shop that runs it. You will hear back within 24 hours to arrange getting the piece to the scanner.
