Frequently Asked Questions

What is Piezography Pro printing process used by blackprint ?

Piezography Pro is a carbon ink-based process consisting only of black inks, created in 2016 by Jon Cone. blackprint is using the process since the same year. The system includes a set of warm and cold tone inks, a matt HD-black, a photo black (glossy) and a gloss chroma optimizer. The process allows the mixing of warm and cool black values either throughout the print or by varying them differently on the light, medium or dark tones. This makes it possible to have a totally personalised black and white print. The new Piezography Pro Matte HD Black is the extremely dark matte black and the Gloss Chroma Optimizer completely eliminates gloss differential and tanning. Finally, the white value of the paper is a very important element for the Piezography Pro as its white tone will influence the final black and white tone of the print too.

What papers are available for printing at blackprint ?

All blackprint editions “Karo collectors“, “Private collection” and “Artists edition” are delivered with a blockchain certificate of authenticity Verisart. Exceptions are the “Karo edition“.

What is a VERISART blockchain certificate of authenticity?

It was crucial for blackprint to ensure transparency in transactions and properties to strengthen the confidence of collectors in the purchasing process, as well as that of the artists represented by blackprint.

Therefore, since September 2022, blackprint issues certificates of authenticity using VERISART blockchain technology for all(*) editions produced in its studio in Zürich (Blackprint edition).

These certificates leverage the decentralization of the blockchain, making it extremely difficult for unauthorized parties to manipulate or create fraudulent certificates.

They guarantee a secure, transparent, and immutable record of each artwork’s details, including information about the artist, provenance, and other relevant details, providing a reliable and easily verifiable record of the origin of each blackprint edition.

Each artist represented in the blackprint edition individually certifies each digital certificate of authenticity.

blackprint currently issues two types of certificates of authenticity:

COA + (Certificate of Authenticity +):
This introduces Secure QR Stickers, a technology of holographic stickers with a unique serial number and a secure QR code for individualized authentication. They are applied to the physical artwork and connected to the corresponding digital certificate.

Certificate of Authenticity:
Exclusively digital certificate without Secure QR Sticker.

(*) Except for certain artist editions and Karo editions #01, #02, #03, and #04.
