フレクコジクレーとは?

Fresco, a fruit of Renaissance art, successfully industrialized

We have successfully industrialized fresco, a fruit of Renaissance art, for the first time in the world by developing plaster sheeting and merging the latest pigment ink-jet printing technology. Thus we have succeeded in the reproduction of fresco by using the ink-jet printer.

フレスコジクレーの画質

フレスコジクレーは、デジタル画像データを元にしながら、アナログ的な自然な奥行き感のある画像が得られます。
この画像は、一般のインクジェット用紙のようなインク受像層を持たず、光透過性と独自のテクスチャーを持つ「未硬化の漆喰」に顔料インクが浸透することで生まれます。

フレスコジクレーの画質

フレスコジクレーの表面には、50~300μmの不連続サイズの突起物があります。
従来のインクジェットのメディアは、30μm程度のピクセル各色が折り重なって発色しますが、フレスコジクレーでは、この突起物にインクジェットのインクが着弾して、あたかも不連続サイズの突起物そのものが色を持っているかのように見えます。
その結果、顔料インクのピクセルで色表現されたデジタル感の残る従来のインクジェットメディアの画質と異なり、フレスコジクレーはディテールに拘った油絵の細密画に見られるような自然な奥行き感が表現されます。

デジタルを感じる要素のひとつに、微妙に色調が変化してゆく空などのグラデーション表現で、階調の連続性がなくなって、部分的に縞模様が見えてしまう現象があります。フレスコジクレーの場合、不連続サイズの突起物へインクが着弾することから、漆喰のテクスチャーによる「ゆらぎ」の要素が加わり、デジタル感を抑えた自然な画像になるものと考えられます。

フレスコジクレーと一般的なインクジェット用紙とに同じ顔料系インクジェットプリンタで印刷した場合、フレスコジクレーの方がより優れた耐光性を発揮することが分かっています。この原因を探るために印刷前後の表面の元素分析を行った結果、印刷した後、漆喰の炭酸化反応によって顔料インクがCaCO3の薄膜で覆われ、有機物である顔料インクの酸化劣化を抑える構造に変化することが分かりました。
この反応は、数ヶ月から一年かけてゆっくりと進行し、作品として熟成されて行きます。 フレスコジクレーは、普遍的な技法であるフレスコのメカニズムを使って、改めて代々受け継がれる「形ある写真作品づくり」を基本コンセプトとした現代のフレスコ画法ともいえます。

Fresco Techniques and Fresco Giclee

FRESCO (Fresh)

Fresco is a plaster-based painting technique used by the Renaissance artists that flourished in Italy from the 14th century to the 16th century, such as Michelangelo and Raphael. Using this technique, an artist would first spread plaster on a wall, and then drew his painting by using pigment colors mixed with water while the plaster was still fresco (fresh), in other words, half hardened.
Fresco is an Italian word for “fresh.”
The famous fresco paintings include the “Last Judgment,” which is displayed on the Sistine Chapel ceiling, painted by Michelangelo in the early 16th century. Thanks to fresco’s mechanism by which pigment colors are contained when the plaster becomes hardened, fresco paintings are preserved without fading even now over 500 years later.

Fresco Technique

Fresco Technique

In fresco, first, the entire area is divided into each different painting area that might be drawn on within a day.
Plaster that is kneaded with water is spread on the area to be drawn on within one day. Then the artist starts to draw his painting after the plaster surface has dried, finishing drawing on within the day.
Pigment colors penetrate into the unhardened plaster; afterwards, these pigment colors are contained within the hardening plaster. For this reason, paints used for fresco painting consist of water and pigment colors without binding agent contained.

The Principle of Fresco Giclee

The Principle of Fresco Giclee

Fresco Giclee was brought forth because we wanted to widely disseminate fresco, what might be called as a fruit of Renaissance art, with our cutting-edge technology.
Why fresco paintings are not produced anymore? It is because fresco is a particular technique by which the artist spreads plaster and draws his painting quickly within a few hours before the plaster becomes hardened. To resolve this issue technically, we developed a technique to make unhardened plaster into sheets. Given this technique, we have successfully revived and brought back fresco into the present with images printed on these sheets by using the latest pigment ink-jet printer.
It takes time for a man to draw a fresco painting. However, this should be a new-generation technique that removes the limitations of time for drawing, which had been the fatal issue of the traditional fresco technique, by using ink-jet printing based on digital data.

・Ink-jet printing sheets for photographers
・Replicas of art museum collections
・Preservation and restoration of cultural properties

Recently, the advancement of digital archives (digital data preservation) has been remarkable in a wide variety of fields of photographs and replicas of cultural properties and paintings.

Product Introduction

Product Introduction

The texture of Fresco Giclee Type R consists of an endless number of discontinuous-sized projections measuring 50 – 300 μm. Given this texture that can be barely visible by the naked eye, the printed image provides a natural sense of depth that can be seen in those realism paintings.
There is a sister product, Fresco Giclee Type S, that has a texture consisting of projections in sizes that can hardly visible by the naked eye.

Product information

Fresco Giclee is plaster sheeting that is printable by using an ink-jet printer.
We have successfully industrialized fresco, a fruit of Renaissance art, for the first time in the world by developing plaster sheeting and merging the latest pigment ink-jet printing technology. Thus we have succeeded in the reproduction of fresco by using the ink-jet printer.
* Fresco Giclee supports EPSON’s pigment ink-jet printers.

Variation

Plaster, which has a texture with fluctuations and light transparency, diffuses light in a complicated fashion. This provides images with a natural sense of depth that can be seen in those realism paintings.

Variation

With the texture that is barely visible by the naked eye, the printed image using this product provides a natural sense of depth. Fresco Giclee Type R is the best choice for scenery images.
“R” stands for “rough”.
After being printed out, the plaster gradually becomes hardened. This hardening process takes a few months to a year.
The printed image can be handled the next day.

What is plaster?

“Plaster” – A wet architectural material that resists aging over the centuries

What is plaster?

Plaster is composed mostly of limestone, a natural material, which is the source of its amazing durability.
Limestone is broadly divided into two types: the sediment of calcium carbonate in the ocean and the skeletal fragments transformed into stone.
Limestone is formed slowly and quietly, over generations that seem to be an eternity or forever.
Akiyoshidai in Yamaguchi, Japan, is a typical example. Here, Akiyoshi-do Cavern which is one of the best limestone caves in the entire Orient is located and the largest karst plateau in Japan spreads over 130km2 where huge limestone rocks exist.
This must be the art that can only be brought about by nature.
Limestone rock of good quality obtained from Akiyoshidai is used as the raw material for Fresco Giclee.

Karst Plateau

To make plaster, first, quicklime is created by burning limestone at 900 to 1000°C, and then made into powdered slake lime by the reaction with water. Next, it is kneaded with mixed water, seaweed, and fibers, and then this powdered slake lime is daubed on a wall and becomes hardened.
Particularly, the finishing fineness of the plaster surface using a trowel really meets the aesthetic sense of the Japanese.
