# Making a classic blue-water city map with the Blue Water Map preset > the timeless web-map look: bright cyan water against a near-white city of soft grayscale roads This is the cleanest, most-loved map aesthetic on the internet: pale grayscale streets on near-white land, with water in a single bold cyan. The contrast does all the work - the eye locks onto the shape of the water first, then reads the city around it. Stockholm is a perfect showcase because its archipelago and inlets push cyan deep into the street grid, so the water becomes a branching, organic shape rather than a flat block. Everything here is solid colour fill and line, so the design lives or dies on that one decision: keep the land light, the roads quiet, and let the water carry the colour. ## What you need ### UV print / sublimation - The exported high-res PNG (4096 px) - UV flatbed printer, or a sublimation setup with a coated white blank (hardboard, aluminium, ceramic) - A bright white blank keeps the cyan water as vivid as possible ### Poster / paper print - The exported high-res PNG sent to a photo lab or printed on smooth matte art paper - A simple white or light wood frame keeps the focus on the water ### Laser (optional, two-tone) - A sheet of cyan acrylic for the water and a white or light backer for the land - Any diode or CO2 laser - Note: treat the water as a cut shape and the roads as engraving - the colour comes from the acrylic, not the laser ## Step 1 - Start from the preset Open [the Blue Water Map preset](/map-designer?preset=blue-water-map). It opens on Stockholm at zoom 12.4 in a square (1:1) frame, which captures the central islands and the surrounding water. Pan so the water reaches into all four edges of the frame - the more the cyan branches through the city, the stronger the look. Any waterfront or archipelago city (Venice, Amsterdam, Vancouver, Helsinki) works just as well. ## Step 2 - Tune the layers The preset is a single layer group, "Blue water city", and every feature is Solid fill or line. The balance between the three tones - land, roads, water - is the whole design: - **Land** - Solid fill, near-white `#F4F4F2`. The bright base that makes the water pop. Keep it light; tinting it grey kills the contrast. - **Water** - Solid fill, bright cyan `#3FC1E0`. The hero colour and the only saturated element. Nudge it toward teal `#2BB0CF` for a cooler look or sky-blue `#5BC8E8` for a softer one. - **Park / landuse** - Solid fill, barely-there `#E6EAE4`. Green spaces read as the faintest shift from the land, so they never compete with the water. - **Roads** - Solid fill, a grayscale hierarchy from medium grey motorways `#7A7F85` (width 5) down to pale street mesh `#CDD1D5` (width 1.2). The roads should sit quietly between the land and the water. - **Tertiary / streets** - The fine mesh that fills the islands; ease the street width down if a dense old town reads too busy. The one rule: only the water is allowed to be saturated. If you recolour the water, keep everything else neutral so the contrast holds. ## Step 3 - Export - **UV / sublimation:** export the high-res PNG (4096 px). Keep the Background toggle on so the near-white land prints as a solid field, or turn it off to let a white blank become the land. - **Poster:** same high-res PNG, sized to your paper. The square 1:1 frame suits a 12x12 or 20x20 print. - **Laser (optional):** export the per-layer SVG ZIP. Cut the Water layer from cyan acrylic, mount it behind a white land layer, and engrave the road network on top. ## UV & Sublimation Printing ### UV print / sublimation 1. Export the high-res PNG. Print onto a bright white blank to keep the cyan as vivid as possible - white hardboard, aluminium, or ceramic all work. 2. For sublimation, mirror the image and press onto a coated white blank per its spec. The whiter the substrate, the punchier the water. 3. On a UV flatbed, lay down a white underbase if printing on anything but pure white so the cyan stays saturated. 4. A matte or satin finish reads as a clean modern map; gloss makes the cyan even more electric. ### Poster / paper print 1. Send the high-res PNG to a photo lab or print on smooth matte art paper - a smooth stock keeps the grayscale roads crisp. 2. Frame in white or pale wood to keep all the attention on the water shape. 3. The 1:1 square crop is set for you - keep it square, or re-export after switching to a portrait ratio for a taller framed piece. ## Laser Cutting & Engraving ### Laser (two-tone cut) The colour comes from the material, not the beam, so build this as a simple two-layer piece. 1. Export the per-layer SVG ZIP. The Water layer becomes a cut shape; the road layers become engraving. 2. Cut the water from a sheet of cyan or turquoise acrylic and mount it behind a white or light backer that shows through as the land. 3. Engrave the combined road network onto the land layer - the line-width hierarchy keeps the major roads legible against the fine mesh. 4. Frame or mount on standoffs for a clean two-tone wall piece. ## Make it yours - Waterfront cities are the sweet spot: Stockholm, Venice, Amsterdam, Vancouver, Hong Kong - anywhere water reaches into the streets. - Cool the water toward teal `#2BB0CF` for a more contemporary feel, or warm it to a sky `#5BC8E8` for a softer, calmer print. - Keep the land truly light - if you want a hint of warmth, go cream `#F6F3EC` rather than grey. - Add the city name and coordinates in a thin modern typeface under the map for a clean editorial look. - Print large (20x20 square) in a white frame as a bright, gallery-clean statement piece. - Turn the street mesh down a touch for a more graphic version that leans on the major roads and the water shape. --- Open the tool: https://www.mylasertools.com/learn/guides/blue-water-map Read online: https://www.mylasertools.com/learn/guides/blue-water-map
