Production Notes
Letter Style
Trimless Front-lit Channel Letters
Direct face illumination without a visible trim-cap border.
Face Systems
Standard acrylic or epoxy resin
The finished appearance is similar; the internal face construction differs.
Standard Trimless Sizing
Depth-to-stroke matrix
Return depth and stroke width must fall within the approved matrix shown in Size & Depth.
Epoxy Minimum Depth
Greater than 0.78"
Epoxy letters also follow the Standard Trimless depth-to-stroke proportion matrix.
Epoxy Stroke Range
Greater than 3/8" and less than 9.44"
Artwork outside this range requires production review or modification.
Epoxy LED Placement
Side-mounted or front-face-mounted
Under 1.77" stroke: side-mounted LEDs. Over 1.77" stroke: front-face-mounted LEDs.
Epoxy Diffusion Material
Selected by stroke width
The diffusion plate or opal-white acrylic thickness follows the system table in Size & Depth.
Returns
Aluminum or 304 stainless steel
Selected around structure, weight, environment, finish, and fabrication requirements.
LED Color
3500K-6500K white or RGBW
Module spacing, power, and controls are planned for uniform face illumination.
Mounting
Direct mount or raceway
Selected around wall type, code requirements, electrical access, and installer preference.
3 / Size & Depth
Dimensional standards for Standard and Epoxy Trimless systems.
Use the Standard Trimless matrix to coordinate return depth and stroke width. Epoxy Trimless letters follow the same proportion standard and add system-specific rules for LED placement and face-material thickness.
Production Standard
Confirm the face system first, then verify return depth, stroke width,
LED placement, and diffusion material before fabrication.
System 1
Standard Trimless Front-lit
Uses a normal translucent acrylic face. Return depth and stroke width must follow the manufacturer’s approved proportion matrix.

Long connected characters or designs with many corners may use opal-white PC in place of acrylic.
Acrylic Reference
1/8" opal-white acrylic
For letter depth greater than 0.78", this is the reference acrylic build, subject to the stroke-specific rules above.
Final Engineering

Exact depth, stroke width, LED position, diffusion material, structure, and service access are finalized before fabrication.
1 / Construction
Two face systems with the same clean trimless appearance.
Compare the normal acrylic face with the epoxy-resin face. The finished 3D appearance is the same; the face construction differs.
System 1
Standard Trimless Front-lit Channel Letters
A normal translucent acrylic face creates a bright, uninterrupted front-lit surface without a visible trim-cap border. Its depth and stroke width follow the approved Standard Trimless proportion matrix.
Cross SectionStandard acrylic face assembly
Shows the translucent acrylic face, metal returns, internal LEDs, letter back, wiring, and mounting interface.
Standard Acrylic Face
Finished EffectClean borderless illumination
The illuminated acrylic face remains visually uninterrupted, with no visible trim-cap profile around the perimeter.
FaceTranslucent acrylic

Visual ResultBright seamless face
System 2
Epoxy Trimless Front-lit Channel Letters
An epoxy-resin layer is applied over the illuminated face, creating a smooth and seamless finished surface. LED placement and face substrate thickness are selected from the epoxy system standards.
Cross SectionEpoxy-resin face assembly
Shows the epoxy surface layer, illuminated face, metal returns, internal LEDs, letter back, wiring, and mounting interface.
