Watercolor Technique

Artist Heidi Rosner pushes the limits of the watercolor medium with her dramatic florals and vivid landscapes. Heidi has a methodical process in which she adds layers and layers of the paint until she gets the intensity level she seeks.

“The most important part of the painting process happens before paint is even involved.  It requires an accurate drawing to define the composition and help to plan out the painting.  Watercolor is a spontaneous medium with no ‘forgiveness’—one mistake and the painting is potentially ruined. And, since I paint with such dark colors, I only get one shot at the painting. The challenge of this medium is why I love working with it.” ~ Heidi Rosner

Heidi developed her signature style by “reverse engineering” the properties of the medium. She determined that by adding layer upon layer of color she could obtain a depth of color not typically seen in watercolor paintings.

“My work is an expression of who I am—I am not a ‘washed out’ person,” ~ Heidi Rosner

Heidi uses both traditional watercolor paper and non-traditional surfaces (such as canvas and board) for her work. Canvas and board yield paintings that rival oils for intensity. Another bonus of her canvas and board works is they do not require glass for finishing, unlike paintings on watercolor paper.

Giclée printing

Heidi Rosner uses the giclée process to create fine art limited edition prints from her original watercolor paintings.

Giclée (pronounced zhee-clay) is a French word which means “spraying of ink”. In this high-tech computer reproduction process, a fine layer of ink—more than four million droplets per second—is sprayed onto archival watercolor paper.  Each droplet is four times smaller than a human hair.

The first part of the process includes making a very high resolution scan from Heidi’s original work. Then, the ink is applied to produce a combination of 512 chromatic changes with approximately 10 million color possibilities of highly saturated, nontoxic water-based ink.

This combination of high-resolution scanning and digital printing gives each image the vibrant and luminous results of an original watercolor—resulting in a print that can be difficult to distinguish from the original.

Each giclée print is protected by applying an extra strength UV coating to insure museum quality. The limited edition is individually hand-signed and numbered by the artist and is accompanied with a certificate of authenticity.

All of Heidi’s lithographs are created with the classic four-color offset lithographic process that has been used to create fine prints for generations.

To create a lithograph, a printing plate is prepared with an emulsion image of the painting. Hydrophobic (i.e., water repellent) ink is then applied with inking rollers. The ink adheres only to the emulsion of the image. If the printing plate were pressed to paper at this stage, a negative of the image would be created. Instead, the printing plate is rolled against a cylinder which picks up the ink and then transfers it to the paper with even pressure.

Heidi’s lithographs are all individually signed and numbered by the artist and include an official certificate of authenticity.
