PlotterPrinters Analyst Desk — Scoring Methodology
How We Rate Wide-Format Printers
No black boxes: if a number is on the page, we can show you the document it came from.
Every printer page on this site carries a Spec Analysis — nine scored dimensions and an overall mark out of 100. This page explains exactly how those numbers are computed, where every input comes from, and what we do when the data is missing.
The nine dimensions
SHT 02 · PLOTTERPRINTERS ANALYST DESK| Dimension | Weight | What feeds it |
|---|---|---|
| Media Handling | 16 | Roll capacity (dual-roll trims credit here), maximum media thickness, cut-sheet support, maximum roll diameter |
| Speed | 16 | The manufacturer’s rated print speed, normalized to ft²/hour. Sustained ratings (prints/hour, m²/h) are preferred; where a vendor publishes only a per-page burst timing, the score is flagged burst-rated |
| Print Cost | 12 | Ink cost per mL, computed from our live supply prices and cartridge sizes — acquisition cost of ink, not a full cost-per-print model |
| Color | 12 | Measured color gamut computed from a real ICC profile (on one common paper wherever possible, so machines compare fairly), plus ink-channel count and on-board spectrophotometer |
| Print Quality | 12 | Maximum resolution, line accuracy, minimum line width, droplet size — the precision specs |
| Workflow | 12 | Page-description languages: Adobe PostScript, PDF, HP-GL/2, raster formats |
| Warranty | 8 | The included manufacturer warranty, in months |
| Connections | 6 | USB, Ethernet, Wi-Fi, Wi-Fi Direct — scored only when at least three are documented |
| Size / Fit | 6 | Footprint (width × depth) and weight — smaller and lighter grade higher |
Graded on a curve — and the curve has names
SHT 03 · PLOTTERPRINTERS ANALYST DESKFor every metric, 100 means the best real value held by an actual machine we track — not a theoretical ideal. The finest droplet, the tightest line accuracy, the longest included warranty each define the top of their scale, and we record which machine holds it, so “100” is always a checkable claim. One deliberate exception: the Speed curve is set by the fastest printer you can actually buy here — a million-dollar industrial press doesn’t get to make every working plotter look slow.
Where the numbers come from
SHT 04 · PLOTTERPRINTERS ANALYST DESKMeasured data — color gamut is computed with ArgyllCMS from real ICC profiles, on a common reference paper (Hahnemühle Photo Gloss Baryta) wherever one exists, so the only variable is the printer and its ink.
Published specifications — datasheet and feed values, parsed with unit-aware rules and physics cross-checks (a 44-inch printer that “weighs 47 lb” gets rejected, not published).
Verified corrections — where sources conflict or a value looks wrong, we re-verify against the manufacturer’s own document and store the source URL plus the verbatim quote. Every correction is auditable down to the sentence.
What we never do: invent a value. If a spec can’t be found or verified, it stays unknown.
Missing data is handled honestly
SHT 05 · PLOTTERPRINTERS ANALYST DESKWhen a machine doesn’t publish a spec, that metric simply drops out and its weight redistributes across what is known — a missing number is never scored as a zero. If less than half of the total weight can be scored, we suppress the overall mark entirely rather than print a misleading one. When two official sources disagree (it happens — regional datasheets), the value is treated as unknown until we’ve verified the manufacturer’s figure, and the verified value carries its citation.
Two frames on every score
SHT 06 · PLOTTERPRINTERS ANALYST DESKEvery score bar shows two reference points: the best in the machine’s own class (36-inch CAD plotters compare against 36-inch CAD plotters — with a link to the full ranked roster) and the best in the whole catalog among printers you can buy. A machine can be the best of three in a thin class; we’ll say “top of 3” rather than hand out a medal. Class leaderboards rank purchasable machines only — a ranking you can act on.
What this is — and isn’t
SHT 07 · PLOTTERPRINTERS ANALYST DESKThe Spec Analysis is spec-derived: manufacturer-published figures, measured color data, and verified corrections, normalized so machines can be compared on the same basis. It is not a timed lab benchmark, and rated speeds are the manufacturer’s claims, clearly flagged when they’re burst figures. Scores are recomputed when the catalog’s data improves, and the gold standards are re-frozen only on deliberate review — so a score never drifts silently.
