Our Heroine, Dot Krause,
Breaks New Ground for Digital Printmakers

Printmaking Goes to the Bank

The Boston Federal Reserve Mural Project
In the year 2000 American digital artist, Dorothy Simpson Krause was commissioned to create a series of pieces to celebrate the history of the Boston Federal Reserve Bank. Using historical documents and photographs from the bank's archives, she made five pieces measuring 32x48 inches.

As the project evolved, a renovation of the fourth floor conference center resulted in two curved wall niches 3.5 inches deep and it was decided that murals, similar to the history pieces, should be created for the niches. One was approximately 5x15 feet and the other 6x20 feet.

Murals Composed of 32-Inch Panels
The curved wall, the depth of the niches and five history pieces were all considerations in planning. The murals were designed to be printed on canvas in panels and wrapped around the edges of stretchers consistent with the history pieces. A one-inch space was left at the top, bottom, and between each panel to emphasize the depth and dimensionality of the images. Five 32-inch-wide panels were designed for the small mural and seven for the large. A three-inch overlap was allowed on all sides for wrapping around
the edge.

Printing time for the panels coincided with the unveling of the first 64-inch wide Mutoh Falcon II High Productivity printer, and Krause flew to Mutoh America in Tempe, Arizona to print with Guy Cipresso, Vice President, Business Development, and Mark Lazure, Application Specialist.

Born to Print Art
Especially suited for the fine art market, the Falcon II is the only eight-color (KCMYLcLmOG) piezo printer currently on the market.

Incorporating 100-plus-year pigmented inks and Dynamic Variable Dot Imaging, the latest development in piezoelectric drop-on-demand technology, the Falcon II can independently adjust the size of the droplets produced by each of its 1,440 nozzles-on-the-fly. The result is finer detail and smoother gradients in highlight areas and crisp colors in the midtones and shadows.

The High Productivity model is the only bi-directional printer that puts the ink down in the same order in each direction. Because inks are semi-transparent, the order in which they are printed is critical. Yellow printed over magenta is orange but magenta printed over yellow is red.

 

Both Ways at Top Speed
This unique eight-color, bi-directional printer provides exceptional quality and high speed. At 1440 x 1440 dpi, the panels printed on the High Productivity printer took 35 minutes each. The 12 panels, printed on Mutoh's 10 mil matte white canvas, were easily completed in less than a day. (A panel printed on the 50-inch Falcon II took nearly two hours.)

The 12 panels were sent from Arizona to Twin Brooks Stretchers in Linconlville, Maine where Chris Polson and Joe Calderwood post coated them with ClearStar Coating Corporations ClearShield Type C semi-gloss liquid laminate. The Type C has solved the problem created by the solvent in some liquid laminates and varnishes which cause the calcium carbonate in matte canvas to migrate to the surface as a grey dust.

Protection from Everything
The ClearShield enriched the color while providing protection from ultraviolet light, airborne particles, moisture and abrasion. It also made the surface more flexible, enabling the canvas to be wrapped around the edges of the custom-made heavy-duty stretchers manufactured at Twin Brooks.

Picked up in Maine, the panels were returned to Krause's studio where gold leaf was added before delivery to the Federal Reserve. Within a week of the installation an additional piece was commissioned.
