Bringing " FRESCO" , a masterpiece of Renaissance art, to the present day

" FRESCO " is an Italian word meaning "fresh" and is a painting technique based on "fresh plaster" used by Renaissance artists who flourished in Italy from the 14th to the 16th century, including Michelangelo and Raphael.

"Fresco Graph" is the world's first artwork technique that revives " FRESCO " in modern times by converting this fresh plaster into sheets ( * ) using the latest technology. FRESCO provides works with the " natural and deep image quality" and " long-term preservation." 

*Patented in European countries and Japan, pending in the U.S. and others.

1. What is a frescograph?

" Fresco Graph " is the world's first " modern fresco technique" that uses plaster as a raw material and combines classical fresco techniques with the latest three-dimensional modeling technology. The "stucco sheet" that is the basis of this technology has been patented in European countries and Japan.


" Fresco Graph " has the following features.

  • Due to the preservation and light resistance of the fresco technique, you can enjoy it for a long time without fading, even without using UV- cut glass.
  • The layered plaster method creates a natural, deep color.
  • The three-dimensional structure of "Matière", created using a uniquely developed technology, increases the presence of the work and allows you to enjoy it as a timeless work.
  • It is also possible to reproduce the expressions of " gold clay'' and " silver clay" in Japanese paintings.


2. Preservability of frescographs

The reason Frescograph has such long shelf life and light resistance is because the uncured plaster reacts with carbon dioxide in the air and forms a lime layer on top of the pigment that has penetrated into the plaster. This lime layer acts as a barrier and exhibits high preservation and light resistance.

Like Michelangelo's Last Judgment, frescoes have been preserved for hundreds of years without fading.

① The pigment applied on the slaked lime [Ca(OH2)] penetrates into the uncured plaster and forms a paint layer.

②After that, slaked lime [ Ca(OH2)] reacts with carbon dioxide [ CO 2 ] in the air, Limestone [ CaCO 3 ] Return to limestone.

③The limestone [ CaCO 3 ] produced contains pigment paints and has a shelf life of hundreds of years.

3. What is plaster?

Plaster is a natural material with a long history that has been used as a building material for shrines and temples since the Heian period. It is one of the extremely durable finishing materials used in castle buildings such as Himeji Castle, and the white plaster walls have continued to protect the original structures for hundreds of years.

The raw material for plaster is limestone ( CaCO 3 ), a white rock known from limestone caves and karst plateaus. Limestone is a natural material that is made up of fossilized fossilized corals.

Plaster is made by reacting quicklime ( CaO ), which is made by burning limestone, with water, and when it dries, it becomes slaked lime ( Ca(OH) 2 ). Stucco is made by adding this slaked lime, water, glue, etc., and applying it to walls etc. with a trowel.

Received the 5th Manufacturing Japan Grand Prize


The Frescograph technology won the 5th Monodzukuri Nippon Grand Prize Excellence Award * in 2013.


Based on " FRESCO ", a classical technique that was difficult to draw, he perfected the latest sheeting technology using plaster, and was highly praised for reviving " FRESCO " in modern times, which led to him winning the award.
