Thickness

40 vs 80 vs 100 vs 200 micron articulating paper

These numbers are nominal thickness values, not a best-to-worst ranking of accuracy, quality, force, or clinical performance.

Short answer

Forty, 80, 100, and 200 micrometres describe nominal material thickness. Thickness is one comparison dimension that can affect handling and the recorded mark under specific conditions, but the cited studies do not establish a universal accuracy ranking. Compare the exact carrier, task, instructions, surface conditions, handling, and verified product information. A paper mark should not be treated as a standalone numerical force or pressure measurement.

Key points

Thickness is one selection dimension, not a quality score.
Study conditions and indicator materials affect what a thickness comparison can show.
Nominal values should be read together with material type and current product documentation.
A larger or darker mark is not a direct numerical force or pressure reading.

40, 80, 100, and 200 μm at a glance

Nominal paper thickness	What the value establishes	What it does not establish
40 μm	A listed ASHUR paper-family nominal thickness	A complete SKU, universal accuracy, or availability in every color and format
80 μm	A listed ASHUR paper-family nominal thickness	A prescribed procedure, force level, or universal performance result
100 μm	A listed ASHUR paper-family nominal thickness	A numerical force or pressure value from mark appearance
200 μm	A listed ASHUR paper-family nominal thickness	Universal superiority, clinical suitability, or a complete product variant

When reusing this table, keep its interpretation limits and read the references and their scope.

The table compares approved nominal values only. It does not create four SKUs or a thickness × color × format availability matrix.

The cards are not drawn to physical scale and do not imply an accuracy ranking or product availability matrix. See the evidence and references library for the source scopes used by this guide.

What the cited research can support

One cited study reported thickness-related differences in recorded contact areas under its specific conditions.¹ Another measured differences between labeled and actual thicknesses in its sample of commercial materials.² A separate laboratory study considered strip thickness together with operator experience.⁴ These source-bounded observations support careful comparison; they do not verify ASHUR performance or establish a universal clinical or accuracy hierarchy.

Practical comparison context

Record the carrier, nominal thickness, physical format, handling method, current instructions, surface conditions, and purpose of the observation. If a workflow depends on a dimensional tolerance, use current approved product documentation rather than assuming that every material with the same nominal label behaves identically.

Thickness and mark appearance are not force measurements

Published research distinguishes visible marking information from computerized force analysis.³ Mark area or darkness should not be converted into a standalone numerical force or pressure value. This is an interpretation boundary, not a claim that all indicator materials behave identically.

Current ASHUR public thickness facts

The approved ASHUR master lists paper thicknesses of 40 μm, 80 μm, 100 μm, 200 μm. It separately lists PETG film thicknesses of 0.015 mm, 0.020 mm, 0.025 mm. These are specification lists, not a variant matrix: the values must not be combined automatically with every color or format.

Unit conversion alone does not establish equivalence, product availability, performance, or coating thickness.

Common questions

Does thinner always mean more accurate?

The cited sources do not establish a universal accuracy ranking. Their findings remain specific to the tested materials, methods, and conditions.

Can nominal thickness identify a real SKU?

No. A thickness list does not prove which thickness, color, and format combinations are commercially available.

What should be checked alongside thickness?

Check the carrier, format, dimensions, handling, applicable instructions, observation purpose, and verified availability for the exact product.
