Choose printed for colour and fast variable data; choose engraved for heat, abrasion or frequent cleaning durability.
Printed labels suit full‑colour, fast‑turnaround variable sets; engraved labels are the safer pick where heat, abrasion or frequent cleaning demand a subsurface legend. Switchboard labels identify circuits, isolation points and hazards on electrical boards and panels. Two construction methods dominate day‑to‑day work: printed and engraved. Each suits different environments, budgets and lead times. This guide compares switchboard labels — printed vs engraved options — so you can choose confidently for your site and conditions.
Inspect
- Check counts and IDs against the packing list before mobilising to site.
- Adhesion test: trial-fit one spare on the actual substrate. After 24 hours, perform a quick tape-pull; if edges lift, upgrade to a higher-tack adhesive or add mechanical fixings.
- Legibility: confirm critical isolations meet your minimum character height at the intended viewing distance.
- Surface readiness: verify panels are fully cured (fresh paint can off-gas and weaken bonds) and free of silicone residues.
Repair and replace
- Incident damage: for scratched or painted-over legends, quote fast by referencing the original job number and the affected board. We keep cut files and data, so remakes match exactly.
- Environment change: if cleaning chemicals or heat profiles change, we can migrate printed labels to engraved or upgrade laminate/adhesive without redesigning the whole set.
- Spares: we recommend holding 3–5% spares for common circuit IDs to avoid delays during shutdowns.
- Field removal: warm the label with a heat gun on low, lift with a plastic scraper, remove residue with citrus remover or IPA, then re-clean before applying the replacement.

Troubleshooting and maintenance
Most label failures trace back to surface contamination, unsuitable adhesives or using the wrong construction for the environment. A short check avoids rework.
- Edges lifting: re-clean the surface and switch to a higher-tack adhesive or add mechanical fixings.
- Print wear: upgrade to a protective laminate or move to engraved for high-touch areas.
- Chemical damage: confirm solvent compatibility; engraved constructions usually improve resistance.
- Fading/UV: review substrate choice and exposure; engraved materials typically outlast printed films outdoors.
- Cleaning: use pH-neutral detergents and soft cloths; avoid strong solvents like MEK/acetone on printed surfaces.
- Graffiti/paint overspray: avoid thinners; use citrus-based removers on printed laminates or simply refit engraved tags.

Frequently Asked Questions
Which label type lasts longer outdoors?
Engraved labels are often chosen for harsher outdoor or frequent‑cleaning environments because the legend is within the material. Printed labels can perform well when the media, laminate and substrate are matched to the exposure. Actual life depends on the complete construction and conditions.
Can you add serial numbers and barcodes to both types?
Yes. Digital production supports variable information such as serial numbers, barcodes and QR codes for both printed and engraved workflows. Printed workflows are commonly efficient for large serialised sets.
Do I need adhesive or holes for mounting?
Adhesive backing suits many smooth, clean, dry panels. Where the surface is textured, contaminated, or long‑term security is required, mechanical fixings such as screws or rivets are often used.
Will printed labels fade in the sun?
Sunlight, heat and cleaning can affect all signage. Printed labels can be protected with suitable laminates and material choices, but performance still depends on UV exposure, substrate and installation quality.
How fast can you produce switchboard label sets?
Lead time depends on proof approval, quantity and production method. Printed sets are often quickest to produce once artwork and variable data are confirmed; engraved sets may add time for material setup.
What artwork files should I supply?
Vector artwork (for example, SVG, PDF, EPS or AI) and clearly identified fonts help ensure crisp results. For variable data, supply a structured spreadsheet or CSV with clear column headers.
Can I match colour codes or add a logo?
Printed labels readily accommodate brand colours, logos and full‑colour graphics. Engraved labels typically use fixed colour combinations from the laminate, providing strong contrast and durability.
