The Future Of C Prints

The Future Of C Prints
Since the beginning of the medium, photographers have sought to make the largest possible sharp prints of their images. The image file size is often a limiting factor for print size. You can up-res a file with excellent results, but at a certain point the apparent resolution does break down. Today's high-res cameras and, in particular, very high-resolution medium-format DSLR backs, are shifting that limiting factor to the output technology. If your files are big enough and your photos are sharp enough, a new Polielettronica printer at Duggal Visual Solutions in New York gives you an attractive option.

Duggal Visual Solutions is a cornerstone of the photographic business that has defined photographic processing since founder Baldev Duggal arrived in the United States from India in the late '50s and then launched his photo-processing business in the 1960s.

The massive 30,000-square-foot facility on 23rd Street in New York City is a sprawling and frenetic hub of activity. My father, a commercial photographer in Manhattan in the 1970s, used Duggal for large output prints; I used Duggal in the 1990s when I attended the School of Visual Arts and needed a shop to process my rolls of Velvia and make Photo CDs.

Entering the front door of the complex feels the same as it did decades ago (albeit, at a different location), when I was a regular. Technicians in white lab coats calmly take orders, answer phones and dispatch packages across the boroughs. Only now the front desk is the proverbial tip of the iceberg, masking the enormous processing and corporate headquarters behind it. It's also the gateway to services at the company's seven buildings at the Brooklyn Navy Yard, each between 30,000 and 40,000 square feet.

With such a powerful command of the photographic output business in New York City and beyond, it's no wonder that Duggal gets some exclusive toys to play with. One such toy is the reason I'm at the company's headquarters: a massive digital HD C-print machine by Italian firm Polielettronica.

C-prints hearken back to the days of Kodacolor and refer to the use of chemicals and photo-sensitive papers to create output versus technologies like lithography or inkjet printing. Digital C-prints keep the color saturation, vibrancy and feeling of film output without needing to reproduce an image via a camera. Feed a digital image to a digital C-printer and out comes an image with the look of film, but it's a digital creation.

Digital C-printers work by exposing the photographic paper with a trio of laser beams and then developing that exposed film in traditional chemicals.While there's a variety of digital C-printers on the market, the Lambda is the most popular (and is also available at Duggal), with an output resolution maxing out at 400 dpi—an apparent resolution of 4000 dpi.

The Polielettronica printer has a 610 dpi maximum resolution and 48-bit color, and provides an apparent resolution of 6100 dpi. Duggal isn't the only company to use the HD C-printer, but it's the only one to have the newest, largest model, which produces output up to 100x50 inches.

With 48-bit color depth, the machine creates images with excellent continuous tone and both highlight and shadow detail.

Installed in March 2013, the Polielettronica has been used by everyone from fashion photographers to cartographers, thanks to the incredibly high resolution of the output. One of the prints that Duggal shows off is a map with type so small, a loupe is needed to see the text—yet under the loupe, the letters are clear and crisp.
