Product Description
Arlon DPF 390 Wide-Width Backlit Substrate - Seamless Up to 16'4" - 19.5-oz Flexible Material - Double-Sided Printable - 6-Year Outdoor Durability
Seamless Large-Format Backlit Excellence
Arlon DPF 390 represents a breakthrough in large-format backlit signage technology, offering seamless widths up to an unprecedented 16'4" for creating massive illuminated signs without visible seams or joints. This satin white 19.5-oz. wide-width flexible substrate is specifically engineered for large sign faces where durability and uniform light transmission are critical to professional results. The 22-mil thick reinforced vinyl substrate delivers exceptional strength (180 lbf/linear in tensile strength) while maintaining the flexibility needed for installation on curved surfaces, light boxes, and awning frames. With 19-21% optimized light transmission and >75% opacity, DPF 390 ensures brilliant, even illumination that makes graphics pop day or night without hot spots or dark areas that plague inferior materials. The double-sided printable surface accommodates a wide variety of decoration methods including direct digital printing (Eco-Solvent, Solvent, UV, Latex), screen printing, PSA translucent vinyl application, and heat transfer methods—giving you maximum flexibility in production workflows. The satin finish (10-20 gloss units) provides a professional appearance that reduces glare while maintaining excellent print quality and color vibrancy. Rated for 6-year outdoor durability and certified by California State Fire Marshal, UL, NFPA 701, and ASTM E84, DPF 390 meets the most stringent safety and performance requirements for commercial installations. The flat, smooth surface minimizes dirt settlement and makes graphic application easier, while the reinforced construction (500x500 denier yarn, 18 threads/sq in) resists tearing and maintains dimensional stability throughout extreme temperature ranges (-41°F to 176°F service temperature). Whether you're fabricating massive retail light boxes, LED menu boards, fluorescent sign cabinets, illuminated awnings, or architectural backlit features, DPF 390 delivers the seamless perfection, uniform illumination, and long-term durability that distinguish professional installations from amateur work. Available in seven seamless widths from 3'6" to 16'4", this versatile substrate eliminates the limitations and compromises of seamed materials.
? Revolutionary Seamless Widths
The game-changing advantage of seamless construction up to 16'4":
Eliminate Visible Seams
Create massive backlit signs without seams, joints, or overlaps. Graphics appear continuous and professional from edge to edge, eliminating the visual disruption that ruins inferior installations.
Uniform Light Distribution
Seamless construction prevents light streaks and shadows at seam lines. Illumination is consistent across the entire sign face for professional day and night appearance.
Faster Fabrication
No time wasted measuring, cutting, and joining multiple panels. Install one continuous piece and you're done—dramatically faster than seamed alternatives.
Reduced Installation Errors
Seam alignment is the #1 source of installation errors in large format. Seamless material eliminates this problem entirely—foolproof installation every time.
Superior Structural Integrity
No seams mean no weak points where failure can occur. The entire sign face is equally strong throughout, with no vulnerable overlap areas.
Professional Appearance
Seamless construction is the hallmark of premium installations. Differentiate your work with the quality that customers notice and competitors can't match.
Available in seven seamless widths from 3'6" to 16'4"—choose the width that best fits your project without compromise.

Frequently Asked Questions
Q: What makes DPF 390 suitable for large backlit signs?
A: Three critical factors: (1) Seamless widths up to 16'4" eliminate visible seams that ruin large installations, (2) 19-21% optimized light transmission ensures brilliant, even illumination without hot spots, and (3) 22-mil reinforced construction (500x500 denier) provides the strength to tension across large frames without sagging. Together, these create the perfect substrate for professional backlit signage.
Q: Can I print directly on DPF 390?
A: Absolutely! DPF 390 is double-sided printable and compatible with all major ink systems: Eco-Solvent, Solvent, UV Curable, and Latex. This gives you maximum flexibility in production workflows and allows you to create reversible graphics or different designs on each side.
Q: What's the difference between the various widths available?
A: All widths feature the same material specifications—the only difference is width. Choose based on your project requirements: 3'6" and 4'6" for menu boards and small light boxes, 6'6" and 8'6" for standard signage, 10'6" and 12'6" for large retail signs, and 16'4" for maximum-width applications where seamless construction is critical. All widths are 164' long.
Q: How does the 19-21% light transmission compare to other materials?
A: 19-21% is optimized for backlit signage—providing brilliant illumination without excessive light bleed or wasted energy. Lower transmission would make signs too dim; higher transmission would create show-through problems and require more lighting power. This range is the sweet spot for professional backlit applications.
Q: Can I use PSA vinyl on DPF 390?
A: Yes! DPF 390 is compatible with PSA translucent vinyl and cast translucent vinyl films. The smooth satin surface allows bubble-free application of cut vinyl graphics or full-coverage translucent prints. You can mix decoration methods—for example, direct print the background and apply cut vinyl for text.
Q: Is DPF 390 suitable for outdoor awnings?
A: Absolutely! With 6-year outdoor durability, reinforced construction (180 lbf/linear in tensile strength), and temperature stability from -41°F to 176°F, DPF 390 is excellent for outdoor awnings. It resists tearing, maintains tension, and withstands weather extremes while providing the flexibility needed for awning frames.
Q: What fire certifications does DPF 390 have?
A: DPF 390 passes NFPA 701-2004 Test 1 and is certified by California State Fire Marshal, UL (Underwriters Laboratories), and ASTM E84. These certifications are critical for commercial installations, building code compliance, and insurance requirements—essential for legal compliance in public spaces.
Q: How do I join sections if I need wider coverage than 16'4"?
A: While seamless is always preferred, sections can be overlapped using the cutting strip method: tape a thin steel strip (2" x 1/16") onto substrate, lay both vinyl pieces over it, cut through all layers with a straight edge and sharp knife, then remove excess and squeegee to create uniform overlap. Overlap 1/4" preferably (1/8" minimum).
Q: Can DPF 390 be used with LED lighting?
A: Yes! DPF 390 works perfectly with modern LED lighting systems. The 19-21% light transmission is optimized for LED illumination, providing brilliant, even lighting with energy efficiency. It's equally compatible with traditional fluorescent tube lighting.
Q: What's the best width for a drive-thru menu board?
A: Most drive-thru menu boards work well with 4'6" or 6'6" widths, depending on the cabinet size. These widths provide seamless coverage for standard menu board dimensions without requiring seams. For extra-large menu systems, 8'6" may be appropriate.
Q: How should I store unused DPF 390?
A: Store in cool, dry environment at 60-75°F with maximum 50% humidity. Keep in original packaging, protect from temperature extremes and direct sunlight. When rolling, use minimum 6" diameter core with graphics facing outward. Shelf life is 1 year under proper storage conditions.
Q: Does the satin finish affect print quality?
A: No—the satin finish (10-20 gloss units) actually enhances print quality by reducing glare while maintaining excellent color vibrancy and detail reproduction. It's the ideal finish for backlit applications where excessive gloss would create unwanted reflections.
