About Us

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.

Archival Standards & Quality Assurance

Every production run undergoes multi-stage quality assurance.

1

Pre-production

Client specification review. Material sourcing verification. Reference standard calibration.

2

Production

In-process colour calibration. Substrate consistency checks. Binding and durability testing.

3

Post-production

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.

Dr. Cordelia March

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.

Our Clients

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.
