Architectural & Interior Design Specification Guide

MK02 Technical & Project Planning Edition

Purpose Of This Guide

This document provides design, technical and coordination guidance for incorporating Wall Envy MK02 direct-to-wall printing into architectural and interior projects.

It is intended for architects, interior designers, builders and project teams specifying direct-to-wall printing in commercial, residential, healthcare, education, hospitality and recreation environments.

Final substrate suitability, machine access and printable area are confirmed following site assessment and final site measure.

Important

Direct-to-wall printing is seamless within the printable area, but it is not seamless within the printable area .

The MK02 requires operating clearances from floors, ceilings, corners and the machine-body side of the wall.

These zones should be allowed for in elevations, artwork development, joinery coordination and project planning from the outset.

Technical Specification Guide

Technology Overview

Wall Envy uses the MK02 vertical-track direct-to-wall printer to apply UV-cured CMYK + White ink directly to suitable architectural surfaces.

The print is produced directly on the wall or substrate, without wallpaper panels, adhesive vinyl or a separate film layer. The result is a continuous graphic within the machine's printable zone, with no panel joins or wallpaper seams.

How The MK02 Works

✓

Horizontal Travel

The printer travels laterally along a floor track while the printhead moves vertically on the mast.

✓

UV Curing

UV curing occurs during printing, eliminating conventional drying periods after printing is complete.

✓

White Ink System

White ink allows opaque elements to be printed over suitable dark or clear surfaces where artwork and substrate conditions require it.

✓

Distance Sensing

Laser and distance sensing helps maintain printhead stand-off across minor surface variation. It does not make severely uneven or obstructed surfaces suitable for printing.

Core MK02 Technical Specifications

Equipment MK02 Vertical-Track Direct-to-Wall Printer
Print Resolution High-definition printing up to 1440 DPI
Ink System UV-Cured CMYK + White
Maximum Print Height Up to 4.0 metres in standard vertical-track setup, subject to site conditions
Print Width Continuous lateral travel across suitable wall lengths. Practical width depends on wall length, floor conditions, access and operating requirements.
Curing UV-Cured During Printing
Print Direction Normally left-to-right. Right-to-left printing is possible, however right-side machine clearance remains required.

MK02 Operating Clearances

The values below are the current planning allowances supplied for the MK02. Treat them as approximate design clearances until confirmed by Wall Envy during final site measurement.

Location Planning Clearance Design Note
Top / Ceiling Approx. 350 mm Leave an unprinted border below the ceiling or overhead obstruction.
Bottom - No Floor Rail Approx. 350 mm Measured from finished floor level.
Bottom - With Floor Rail Approx. 450 mm Allow larger bottom margin where floor-rail configuration is used.
Left Side Approx. 100 mm Clearance at the printhead side of the system.
Right Side Approx. 700 mm Required for the main machine body and control box. This clearance remains even when printing direction is reversed.

Printable Area, Substrates & Site Conditions

Printable Wall Area

✓

Printable areas must be flat enough for the printer to track safely and must remain unobstructed.

✓

Do not design through pipes, conduits, wall-mounted fixtures, switches, power points, signage hardware, handrails or other protrusions.

✓

The printer does not wrap around internal or external corners.

✓

Maintain a clear unprinted border at adjoining walls and corners.

✓

Doorways, windows and other openings must be treated as separate no-print zones.

✓

Final artwork dimensions should only be locked after Wall Envy confirms the usable print zone onsite.

Design Rule

Think of the wall as a printable rectangle inside the architectural wall.

The graphic sits within that rectangle rather than running fully into every edge, corner, floor junction or ceiling junction.

Substrate Compatibility

The MK02 can print on a wide range of porous and non-porous architectural surfaces, subject to surface condition, adhesion and site suitability.

Porous / Absorbent Surfaces

Gyprock / Plasterboard

Painted Plaster

Rendered Concrete

Raw Brick (subject to texture)

Timber & Plywood

MDF & Paper-Faced Boards

Non-Porous / Sealed Surfaces

Glass

Architectural Metal

Ceramic Tile

Acrylic Panels

Other Sealed Surfaces Subject To Compatibility Testing

Surface Preparation

✓

The substrate must be clean, dry, structurally sound and free of loose paint, dust, grease, silicone residue and flaking coatings.

✓

Walls should be complete and painted before printing unless Wall Envy advises otherwise.

✓

Highly porous, glossy, dark or unusual surfaces may require primers, base coats or testing.

✓

Fresh coatings must be fully cured in accordance with manufacturer guidelines.

✓

Finished floors should provide a stable and reasonably level machine path.

Artwork & Colour Planning

✓

Supply high-resolution artwork at the largest practical size. Vector artwork is preferred for logos, typography and linework.

✓

Allow for all confirmed no-print margins, openings and obstructions in final layouts.

✓

Digital mock-ups are used for scale and placement approval. Colour appearance can vary depending on wall colour, texture and lighting.

✓

For critical brand colours or unusual substrates, specify a sample or test print prior to final approval.

Durability, Cleaning & Environmental Notes

Expected Print Life

Environment Typical Supplier Guidance Key Variables
Interior Approx. 8-10 Years Substrate, wall preparation, cleaning, abrasion and UV exposure.
Exterior Approx. 3-5 Years Direct sun, weather exposure, substrate, orientation and local conditions.
Protective Coating May Extend Service Life Compatible clear varnish may be considered where additional protection is required.

These are general supplier-life estimates and should not be interpreted as project warranties.

Actual longevity depends on wall system design, environment, substrate condition, exposure and intended use.

Exterior installations and high-contact interior environments should always be assessed individually.

Cleaning & Protection

✓

Use soft, non-abrasive cleaning methods.

✓

Avoid aggressive solvents, scouring pads and repeated hard abrasion unless compatibility has been confirmed.

✓

In high-contact, hospitality, education or exterior environments, discuss whether a compatible protective clear varnish is suitable for the project.

✓

Damage to underlying coatings or substrates may affect the printed finish.

Consultation & Prototyping

Wall Envy provides site measures, design consultation, scale validation and digital mock-ups for suitable projects across the Central Coast, Newcastle and Hunter regions.

Early involvement is encouraged so printable wall zones, clearances and service locations can be coordinated before construction is complete.

Technical Note

This guide is intended for design coordination and preliminary specification.

Machine clearances and performance values are based on current MK02 information and may vary with equipment configuration, substrate condition, floor level, wall geometry and site access.

Final printable area and suitability must always be confirmed by Wall Envy before artwork is released for production.

Architects • Designers • Builders

Specify The Wall Early. Design The Printable Zone. Print The Impossible.
