Editorial methodology

Every figure carries an evidence level

At TRIDYsign there is no such thing as a figure without an origin. Every factual claim we publish declares where it came from, and that label travels with the figure in the interface, not in a footnote nobody opens. We use exactly four levels:

• Verified fact. Confirmed against a primary source cited at the foot of the page: a technical standard, an official document, or a manufacturer datasheet cross-checked against an independent source.
• Manufacturer figure. Published by whoever makes the machine or the material. We reproduce it because it is the official number, and we state plainly that TRIDYsign has not confirmed it with its own measurements. This is the most common level for maximum speeds and temperatures.
• Measured by TRIDYsign. Our own measurement, taken with the machine or material in hand, with the procedure documented on the page. It is the most expensive level to produce and, for that reason, the rarest.
• Editorial analysis. A reasoned interpretation by the team: who a machine suits, what trade-off a design decision implies, what risk a buyer takes on. It is argued opinion, and it is labelled as such so that nobody reads it as a measurement.

The distinction matters because all four look alike once they are written in the same tone. Separating them is the difference between informing and merely sounding informed.

Where specifications come from

Specifications are taken only from official manufacturer sources: their site, their datasheet, their support wiki or their manual. We do not copy specifications from shops, marketplace listings or other publications, because that is where errors replicate and fossilise.

When a manufacturer does not publish a figure, the page shows an em dash and the not-published label. We never estimate, never interpolate from a similar model and never fill the gap with a competitor number. A missing figure is information in itself: it says the manufacturer chose not to state it.

When two official sources contradict each other — which happens more often than you would think between the box, the website and the manual — we say so on the page and cite both.

Every price carries the date we verified it

In Mexico, the price of an imported printer moves with the exchange rate, with duties, with seasonal promotions and with the specific seller. A price without a date is not data: it is misinformation wearing the costume of precision.

That is why the data schema makes it impossible to store a price without its verification date, and the interface always shows both together, alongside the seller where we saw it. Published prices are indicative, in Mexican pesos, and exclude shipping and import taxes. Confirming with the seller before buying remains the reader responsibility, and we say so on every page.

Sources cited with a consultation date

Every article ends with its source list. Every source carries a title, a link, a type — manufacturer, standard, press, community, retailer or another publication — and the date we consulted it. The consultation date matters because product pages get edited without notice: if a manufacturer changes a figure next month, readers know which version we wrote against.

Retailers are only cited as a source of prices, never of specifications.

What we test and what we do not

We are a new publication, and most of our coverage today is specification and documentation analysis, not lab testing. We say so on every page, at the top, with no fine print. The full detail lives in the review and testing policy.

Corrections are logged, not erased

When we correct a factual error, the correction is recorded with its date in the update history of the article itself, visible to anyone. We do not quietly rewrite history. The full procedure, including the difference between a typo and a substantive correction, is on the corrections page.

What we do not do

Some decisions were made once and are not renegotiated per article:

• We publish no star ratings and no aggregate scores. A number from 1 to 10 hides the criteria instead of explaining them.
• We accept no paid content, advertorials or sponsored mentions inside guides.
• We grant no copy approval to any manufacturer or distributor.
• We do not host or redistribute third-party 3D files: we link to the original creator on their platform, under their licence.
• We do not invent contact details, certifications, lab equipment or headcount. If we do not have it, the page says so.

Independence and funding

TRIDYsign is an independent editorial publication. We are not a reseller, we do not sell printers or materials, and we are not affiliated with any manufacturer. Some outbound links may earn a commission, and that is explained without euphemism in the affiliate disclosure. No commission decides what we recommend, or in what order.

If you find a page where any of these rules is not being followed, write to correcciones@tridysign.com. That is exactly the kind of message we want to get.
