Safety Instruction Sign Tri-Layer Engraving Sheet LYS-WGB027 combines a matte white face, black middle layer and safety-green base in one true 1.5 mm front-engraving material. Shallow engraving reveals recessed black instructions, while a deeper pass reveals recessed green panels and symbols. White lettering inside a green field is produced by leaving the original white face unengraved while the surrounding area is engraved to green. The colors are integral material layers rather than printed ink or paint fill. An acrylic-base version is supplied for CO2 laser orders, while an ABS-base version is supplied separately for CNC and rotary production. Typical B2B uses include machine-area safety instructions, laboratory PPE plates, warehouse operating rules, workshop procedures and facility safety-information panels.

Product Description
LYSHIRE SAFETY-INSTRUCTION SERIES | LYS-WGB027
Safety Instruction Sign Tri-Layer Engraving Sheet
LYSHIRE LYS-WGB027 is a true white-face / black-middle / green-base tri-layer engraving sheet developed for safety instruction signs that combine a white background, black operating text and green information panels. A shallow pass reveals recessed black instructions; a deeper pass reveals recessed green fields and symbols. White lettering inside a green field is formed by leaving the original white face unengraved while the surrounding field is engraved to green.
Color StructureWhite / Black / Green
Depth-Controlled RevealShallow Black / Deeper Green
Total Thickness1.5 mm Tri-Layer Sheet
Safety-Instruction Color Logic
Black Instructions and Green Panels from One White Face
Shallow Engraving Reveals Black
Removing only the white face exposes the black middle layer for operating rules, PPE instructions, facility procedures and explanatory text.
Deeper Engraving Reveals Green
A controlled deeper pass reaches the green base for header panels, safety symbols, section blocks and selected visual guidance.
White-on-Green without Printing
When the green field is engraved around untouched letter shapes, the original white face remains visible as white text inside the recessed green panel.
Three Integral Colors within a Total Thickness of 1.5 mm
The matte white face, black middle layer and green base are contained within one finished 1.5 mm sheet. LYS-WGB027 is not a stack of three thick boards and does not depend on printed ink, vinyl lettering or paint filling. Controlled engraving depth creates the black and green information levels inside one thin professional engraving material.

Processing
Separate Laser and CNC / Rotary Configurations
LYS-WGB027 is supplied with an acrylic base for CO2 laser work or an ABS base for CNC / rotary engraving. The fabricator controls depth to select the black middle layer or green base layer. Test settings should be established on the ordered configuration because power, speed, tool geometry and machine condition affect the final depth.
- Shallow pass for recessed black body text, rules and identification
- Deeper pass for recessed green panels, blocks and safety symbols
- Reverse-area engraving to retain white lettering inside green fields
One Appearance, Two Process-Specific Base Materials
For CO2 laser engraving and cutting, specify the acrylic-base version. For CNC or rotary engraving, routing and drilling, specify the ABS-base version. Do not assume one physical sheet is universal for every machine; confirm the process, equipment, required reveal depths and finished-sign specification before production.
B2B Applications
Industrial Safety-Instruction and Operating-Rule Signs
The white face supports a clean information background, while black and green reveal depths organize instructions, panels and symbols without secondary coloring. Typical fabrication includes:
- Machine-area safety instructions and guard-operation notices
- Laboratory PPE and workplace-behavior instruction plates
- Warehouse aisle, handling and hazard-reporting rules
- Workshop procedures and contractor safety-information boards
- Facility operating rules and multi-section safety panels
Color Layout Support Is Not Automatic Sign Compliance
The white, black and green structure can support safety-instruction layouts that use white backgrounds, black body text and green information panels. Final wording, symbols, dimensions, placement, substrate grade and legal compliance remain the responsibility of the sign fabricator and end user under the rules of the destination market.

Buyer Questions
Frequently Asked Questions
How does LYS-WGB027 create black text and green panels from one white face?
A shallow engraving removes the white face and reveals the black middle layer. A controlled deeper pass reaches the green base layer. White lettering inside a green field is retained by engraving the surrounding field while leaving the white letter shapes untouched.
Is LYS-WGB027 three thick sheets laminated together?
No. The total finished thickness is 1.5 mm, including the white, black and green layers. It is one thin tri-layer engraving sheet.
Can it be supplied for both CO2 laser and CNC / rotary processing?
Yes, as separate process-specific configurations. CO2 laser orders use an acrylic base, while CNC / rotary orders use an ABS base.
Does the three-color result require printed ink or paint filling?
No. Black and green are integral material layers, and white is the original face. Correct depth control creates the three-color layout without printed ink or paint filling.
Does the material itself guarantee compliance for a finished safety sign?
No. The material provides a useful white, black and green color structure. The fabricator and end user must verify the finished sign design, symbols, text, size, placement and performance requirements for the destination market.
