A surface-selection resource, not a natural-stone equivalence claim
Digital inkjet decoration can create stone-inspired colour and veining on architectural terracotta. A successful selection depends on the approved sample range, panel module, image scale, joint layout and viewing distance. This guide preserves LOPO’s archived PM554 record and full selection board while replacing the legacy comparison claims with project-specific checks.
Read a printed surface as part of a facade composition
A close sample shows colour and printed detail, but the completed elevation also includes panel orientation, joint rhythm, corners, openings and different viewing distances. Stone-inspired does not mean identical to a particular natural slab. The approved visual target should therefore describe acceptable tone, contrast, veining and pattern repetition rather than rely on an absolute “real stone” promise.
Digital image files, inks, glaze or surface layers, firing conditions and the clay body all contribute to the result. The 2016 source does not identify the production file, colour tolerances or current process limits, so present-day manufacturability and matching must be confirmed with current samples and technical review.
Archived PM554 specification
The original article was published on 22 November 2016. Its PM554 values are retained below as historical product information, with unit typography normalized. Every field requires confirmation from current documentation, samples, manufacturing review and a commercial quotation before use.
Keep every historical colour reference visible
The original selection board records nine identifiers: PM820, PM826, PM552, PM550, PM259, PM255, PM554, PM256 and PM258. They are preserved exactly as printed, including PM554 from this article. Treat them as archive references only; do not assume current SKU status, availability or an exact present-day colour match.
Project checks before approving a digital inkjet finish
Sample range and lighting
Review more than one representative sample where variation is intended. Compare colour and contrast under the light, orientation and viewing distance relevant to the facade.
Module and pattern repetition
Map the print scale to actual panel dimensions and elevations. Check repeated motifs, rotations, cut panels, corners and transitions instead of approving a small isolated image.
Joints and interfaces
Coordinate panel joints with windows, edges, parapets and adjacent materials. The visual surface does not determine the clips, rails, brackets, anchors or cavity details.
Performance and maintenance
Require current product and whole-system evidence for structural, fire, water, thermal and acoustic criteria. Obtain cleaning and colour-retention guidance for the approved surface; no universal maintenance claim is made.
Use the application image as appearance context only
The retained photograph shows a pale stone-look facade and a magnified surface inset. It demonstrates how a warm printed finish can contribute to a repeated elevation. The source does not identify the project, panel dimensions, installed quantity, architect, contractor, fixing layout or measured performance, so none is inferred.
Compare current options with project documents
Review the Terracotta Rainscreen page for current panel context and the Ventilated Terracotta Rainscreen Layers and Coordination guide for the relationship between panels, cavity, supports and backing wall. Use the Architectural Terracotta Gallery for visual discussion without treating photographs as specifications.
