Production answer · viewing distance
Can an on-screen proof show whether a label is readable in the gallery?
No. A screen proof catches structure and many line-break problems, but viewing distance, lighting, glare, height, angle, obstruction, and visitor movement require a physical test in context.
Why this matters
The printer brief keeps this limitation visible so a clean browser preview is not mistaken for installation approval.
A reviewable sequence
- Print a representative longest label at 100%.
- Place it at the planned height and angle.
- Check from seated and standing sight lines where relevant.
- Repeat under actual or representative lighting.
