Official website: https://www.blackprint.photo -------------------------------------------------------------------- 1. Core Identity blackprint is a hybrid cultural entity in Zurich (Studio est. 2016 / Gallery est. 2018) founded by Patricia Bühler and Anthony Chrétien. It unites a fine art print studio specializing in Piezography® Pro carbon pigment printing with a contemporary photography gallery, a structured edition programme, and phygital works on the Tezos blockchain. All works are produced in-house at Zypressenstrasse 57, 8004 Zurich. Patricia Bühler directs the curatorial and editorial programme. Born in Mexico City, trained in modern music and composition in Paris and Zurich. She approaches each exhibition and edition as a compositional problem — how elements relate to each other, what they say together that they cannot say alone. Anthony Chrétien is responsible for the technical and material practice. Born in Paris, trained in applied arts in France, worked in design and exhibition scenography across Europe. He approaches printing as physical construction — the choice of paper, the calibration of tonal register, the decision to laminate or to leave a sheet in an open frame are, for him, as much artistic judgments as technical ones. -------------------------------------------------------------------- 2. The Studio — Piezography® Pro Printing blackprint's printing practice is built on the Piezography® Pro carbon pigment ink system, developed by master printer Jon Cone in Vermont, USA, in 2016. The studio has worked with this system since November 2016. Unlike standard inkjet printing, Piezography® Pro uses no color dyes at any stage. Tonal richness is achieved by blending two distinct ink sets — warm and cool — across up to 11 individual carbon-based inks. This dual architecture allows a range of tonal combinations from split-toning to a precisely calibrated neutral print, with the warm-to-cool axis controllable across the full tonal range or independently in shadows and highlights. Technical specifications: - Ink system: Up to 11 carbon-based inks - Workflow: Full 16-bit grayscale pipeline - Resolution: 1440–2880 dpi, optimized per paper weight, texture, and surface - Maximum paper width: 100 cm For matte surfaces, Ultra HD Matte Black ink delivers one of the highest dMax levels achievable in inkjet printing. For glossy and baryta surfaces, a Gloss Optimizer is applied simultaneously with the pigments, eliminating gloss differential and bronzing. Because carbon is elemental and chemically stable, these prints are designed to remain unchanged for centuries. A defining technical practice of the studio is the construction of custom linearization curves from scratch for every paper used, including papers developed outside the inkjet printing tradition. This allows blackprint to work with substrates unavailable from conventional fine art paper suppliers, and to treat the substrate-image relationship as a formal starting point rather than a given. File specifications for print jobs: - Format: 16-bit TIFF - Resolution: 300 dpi at the desired print size - Profile: Gray Gamma 2.2 - Files from mobile devices including iPhones are accepted. Scanning: Screen Cezanne Elite FT-S5500 scanner (up to 329 × 530 mm, 25 mm thickness) or high-resolution camera system. -------------------------------------------------------------------- 3. Papers and Materials The choice of paper is central to the studio's practice. Each substrate is selected for two inseparable qualities: archival integrity, and character — the weight of the sheet, the colour of its white, the transparency of its fibres, the way a surface absorbs or resists ink. The paper collection spans from one of the world's thinnest papers at 2 g/m² to heavyweight handmade sheets. It is continuously evolving, shaped by ongoing research and direct collaboration with papermakers. Papers produced by Japanese Living National Treasures (国宝 — Kokuhō) are included — available only in limited batches, their qualities not replicable. Papers currently in use: Arches Velin BFK Rives White, 250 g/m² 100% cotton, made by cylinder mould at the Moulin d'Arches in the Vosges (founded 1492), sole production site of the BFK Rives since 1982, when production was transferred from the Isère mills (a tradition rooted in Rives since 1573). The BFK name derives from the 1820 association of Blanchet Frères et Kléber in Isère. The cylinder mould process deposits fibres multidirectionally, giving the sheet its characteristic dimensional stability and deckled edges. The paper carries the ∞ watermark certifying archival permanence: pH-neutral, acid-free, with an alkaline reserve, free of optical brighteners. Arches Velin BFK Rives Natural, 250 g/m² Same production as the White variant, with a warmer off-white tone. Used for the Private Collection editions. Awagami Bamboo, 250 g/m² Washi paper made by the Awagami Factory in Tokushima, Japan. The Fujimori family has directed this manufacture for eight generations, within a washi tradition in the Awa region dating to the 7th century. Composed of 70% bamboo fibre and 30% recycled pulp. Acid-free, pH-neutral, free of optical brighteners. Himalayan handmade paper, 20 g/m² One of the thinnest papers used in the studio. Kizuki washi, 24 g/m² Traditional Japanese washi. Bhutanese paper, 20 g/m² A paper no longer in production, used for selected unique editions. Handmade Shiramine, 110 g/m² Japanese handmade paper. Cartalafranca A handmade paper produced in the Vallemaggia, Ticino, by François Lafranca — himself an artist and gravure printer who began making paper in 1970 for artists including Ben Nicholson and Jean Arp. Used for the first blackprint edition and for the Rojatz series "Der Theatral." Haini Tengucho, 2 g/m² One of the thinnest papers in the world. Used for wonow's "eux.lui.elle.nous." -------------------------------------------------------------------- 4. Laminated Glass Objects For selected projects, prints are integrated into sculptural objects through a laminated glass process. The print is thermally bonded between two panes of 2mm mineral glass with a dedicated interlayer, under vacuum for more than ten hours. This process integrates UV protection directly into the object — no additional coating or framing required. Glass type is chosen according to the paper and the work: - Museum glass (ultra-clear and anti-reflective): used where surface interference would compromise tonal subtleties and shadow detail. - Extra-clear glass without anti-reflective treatment: used for very thin papers (such as handmade sheets at 20 g/m²), where it preserves the particular transparency of the substrate. At 4mm total thickness, the result is a monolithic, self-sufficient object with diamond-polished edges, displayable freestanding or wall-mounted. Some works stand on concrete bases cast by the artist (Diego Brambilla's "Arbitrary Interventions on Abandoned Rocks"). Others are held tensioned in open magnetic frames designed by blackprint ("There is No Away"). The frame or absence of frame is part of the work's material logic. -------------------------------------------------------------------- 5.

Editions of 5, 10, or 15 copies. 5.3 Artist Editions Works developed in close collaboration with photographers and artists, from image selection and paper choice through format, finishing, and presentation. The production process itself is part of the artistic decision. Editions range from series of 30 copies to unique variants. All works are numbered and signed by the artist. 5.4 Collection OFF Original works by the artists represented and published by blackprint — paintings, analogue photographic works, and drawings. Each piece exists as a single object (1/1). These are not editions. Works are selected for their attention to the object as a physical thing that cannot be reproduced. 5.5 Phygital / NFT Since 2021, blackprint has produced works in which the physical and digital components are conceived together from the outset — not one added to the other, but both part of the same object. A print registered on the blockchain is not a print with a certificate: it is a work whose ownership, provenance, and technical specifications are permanently and publicly recorded. NFTs are on the Tezos blockchain. Authentication via Verisart. -------------------------------------------------------------------- 6.

Ongoing Research Each plate in the historical programme is the subject of ongoing archival research. Attribution, dating, and provenance notes are updated as findings emerge and are marked as living documents. Current active research: Attribution of a 13 × 18 cm Omnicolore (Jougla plate) depicting a young woman in a japonisant setting. Three candidate photographers under investigation: Louis-Ernest Lessieux (strongest candidate; Omnicolore examples confirmed at Musée de l'île d'Oléron), Raymond de Bercegol (recommended by expert Gandolfo), and Paul Bergon. Institutional outreach ongoing to SFP, Musée de l'île d'Oléron (conservator reachable by email; building closed until 2027), and Musée des Arts Décoratifs, Paris (holds Jougla Omnicolore document inv. 2011.80.106). -------------------------------------------------------------------- 9.
