“Matte black plastic” is not a specification. PC/ABS, RAL 9005, 30 GU gloss, Ra 0.8, 3° draft, UL94 V-0 is. This builds the sheet that travels from your studio to the factory — one row per part, printable, and free.
Grain & roughness
Grain is the texture the mould carries; Ra is the measurable roughness. A supplier can match a grain reference far more reliably than the word “textured”.
Draft angle
The taper that lets a part release from the mould. A textured surface generally needs more draft, not less — the texture itself is undercut.
The right hardness scale
Shore A for elastomers, Shore D or Rockwell for rigid plastics, HB or HRC for metals. Quoting the wrong scale is the most common error on a spec sheet.
Flammability & UV
UL94 for plastics, CAL 117 or FMVSS 302 for upholstery, plus hours of accelerated weathering. Not optional in a regulated market.
What it does not do. Pantone codes match against a built-in list and are approximate — an exact match needs a licensed Pantone library, so confirm against a physical guide before tooling.

Frequently asked questions
Is this free?
Yes — no account, no trial, no export limit. CMF documentation is usually locked behind a PLM seat; this is the one document most often needed and most often missing.
Does anything get uploaded?
No. It is HTML, CSS and JavaScript running in your browser. Your project data never reaches a server, which also means it is never backed up.
Can I export to Excel?
Yes. The Excel button downloads a spreadsheet with a project sheet and the full spec table. Columns you have not used are left out, so you are not tidying up empty fields.
Which hardness scale should I use?
Shore A for soft rubbers and foams, Shore D for hard elastomers, Rockwell R or M for rigid plastics, HB or HRC for metals. State the scale alongside the number — “85” alone means nothing to a supplier.
Does it replace a PLM system?
No. Revision control, approvals and BOM linkage are what a PLM does, and this has none of them.
