J. B. Fowler has produced, preserved, and authenticated projective assessment stimuli since 1968. We print to standards usually reserved for bank notes and legal instruments. Colour calibration at the micron. Substrate consistency across print runs.
The company is proud of consistent quality assurance maintained over five decades of operation.
Custom printing of projective instruments. Archival-grade substrates and inks. Colour calibration to validated reference standards. Print-run documentation and chain of custody records.
Long-term storage in climate-controlled facilities. Temperature and humidity monitoring. Condition assessment and preventive conservation. Digital cataloguing and inventory management.
High-resolution scanning with spectral calibration targets. Quality assurance against original specimens. Validation against perceptual equivalence standards. Digital asset management with unique identifiers.
J. B. Fowler is an independent family-run specialist printer, established 1968.
J. B. Fowler was established in 1968 as a specialist printer of psychological assessment materials. From the beginning, we understood that assessment validity depends on precision at every stage: design, production, distribution, and preservation.
For over five decades, we have been the primary supplier of projective materials to research institutions, academic programmes, clinical practitioners, assessment vendors, and archives.
In 2024, we reviewed our acquisition procedures in response to sector-wide developments in assessment material governance. All findings were addressed through enhanced vetting protocols and closer collaboration with our standards partners.
Established: 1968
Location: London
Clients in 22 countries
ISO 9001 quality assured
Climate-controlled archival storage
Every production run undergoes multi-stage quality assurance.
Client specification review. Material sourcing verification. Reference standard calibration.
In-process colour calibration. Substrate consistency checks. Binding and durability testing.
Final colour verification. Condition documentation. Chain of custody initialisation. Authentication marker embedding.
For materials requiring restricted access, we implement dual-custody protocols, swipe-card access facilities with surveillance, and detailed access logs. All personnel with archival access undergo background verification and sign binding non-disclosure agreements.
Trusted by research institutions, assessment vendors, and archives across 22 countries.
Archival preservation partner. We manage the digitisation of the Institute's 4.7M protocol archive and provide climate-controlled storage for restricted materials. projectivesciences.org
Digital validation partner. Our digitised materials are validated against PAG perceptual equivalence standards. perceptan.org
Stimulus production partner. We produce the physical inkblot materials that underpin Obscura's digital assessment platform. obscura.ink
We supply projective assessment materials to academic programmes, clinical research facilities, and institutional archives. Client references available on request.
J. B. Fowler is managed by a small team of production specialists, archivists, and client relations professionals.
Director of Ethics and Commercial Partnerships
Dr. March oversees our standards partnerships, commercial relationships, and ethical governance framework. Her career has spanned multiple roles across the projective assessment sector: she co-founded Inkwell Games, where she first worked with J. B. Fowler as a client (2012–2016); she later joined the Institute for Projective Sciences as Director of Research Integrity; she subsequently founded the Perceptual Analytics Group and Obscura. At J. B. Fowler, she bridges archival heritage and digital innovation.
We serve research institutions, assessment vendors, and archival facilities. Client relationships are established through professional referral and institutional introduction. We do not accept unsolicited sales approaches.
Following the 2024 sector-wide review of assessment material governance, J. B. Fowler has completed a comprehensive update of its acquisition vetting procedures.
J. B. Fowler commenced digitisation of the Institute for Projective Sciences' 4.7M protocol archive. The project involves high-resolution scanning and spectral colour calibration of archival assessment materials.
Completed production of eight symmetrical inkblot cards on archival cardstock for Inkwell Games' title Percept. Print run: 47 copies. This remains one of the smallest production runs in the company's history.
