ICS Echo (International Code of Signals) Holographic STICKER Die-Cut Vinyl Decal
This design reproduces the Echo flag of the International Code of Signals, a square bicolour flag that sends a single letter of the maritime alphabet.
Visual Elements & Composition
The flag is split horizontally into two equal fields, with the upper half in solid blue and the lower half in solid red. Nothing else competes for attention: there are no borders, numerals or lettering, only the two colours meeting along a clean centre line. The flat vector construction keeps the edges crisp and the proportions square, so the flag reads as a single bold block of colour from across a room.
Meaning & Symbolism
The International Code of Signals assigns each flag a fixed meaning, and Echo signals "I am altering my course to starboard." Its blue-over-red layout belongs to a standardised system developed for ships to communicate across language barriers, a system that still anchors visual signalling at sea. The design's power comes from that restraint: two colours and one division carry a complete message that sailors read at a glance.
Made to Follow Its Own Outline
A flag is defined by its square edges, and this sticker is cut to exactly that outline, so the artwork needs no background or frame to stand on its own. Placed on a laptop lid, a notebook cover or a toolbox, it reads as a small piece of signal equipment that shows the hand of a navigator rather than a generic graphic. Its clean geometry suits a surface that is seen up close and in passing, where the blue and red halves do all the work.

Holographic vinyl decals with a high-contrast rainbow sheen, printed with eco-friendly inks on premium, weather-rated film. Waterproof, UV-protected, and available in five sizes.
Built to turn heads and hold up outdoors. These holographic decals use premium printable vinyl topped with a UV-protective laminate. The film is rated for multi-year outdoor exposure, so the color stays bold and the surface resists scuffs and sun fade.
- Signature finish: a 99% opaque rainbow effect that shifts with angle and light—clean edges and a smooth, matte-sheen feel rather than a mirror gloss.
- Waterproof: designed for rain, splashes, and regular washing on smooth, non-porous surfaces.
- Eco-conscious printing: vibrant, high-density color produced with eco-solvent inks for sharp lines and rich gradients.
- Color guidance: no white underbase is applied; pure white areas won’t print, and very light tones allow the holographic layer to show through. Darker tones deliver the strongest contrast.
- Easy-peel backing: release liner separates cleanly for quick, bubble-free placement.
Made for smooth surfaces: glass, metal, coated plastics, sealed laptops, bottles, mirrors, lockers, and windows. Suitable for interiors and short-term exterior spots like vehicle windows or signage.
- Prep: clean the area with mild soap and water or 70% isopropyl alcohol; let it dry fully.
- Apply: peel, align, and press from the center outward with a card or squeegee to push out air.
- Set: allow 24 hours for the adhesive to reach full bond; avoid heavy moisture during this time.
Tips: Avoid heavily textured or silicone-coated surfaces. For curved items, apply slowly and don’t stretch the film.
- Wipe with a soft, dry or slightly damp cloth from the center outward to lift dust and grime.
- Avoid abrasive pads, harsh solvents, or pressure washers that can dull the holographic layer.
- If placed on bottles or mugs, hand-wash is recommended. Prolonged high-heat cycles can shorten adhesive life.
Available in five sizes. Measurements refer to the longest side of the decal. A “3 inch” option is 3 inches across its largest dimension; the die-cut follows the exact contour for crisp, professional edges.
