Scanning
Anyone who has ever reproduced works of art is aware of how much work goes
into the capture and scanning. While digital camera scanners have improved
keep your eye on the light system and the software. Ideally digital CCD
Scanners work best in Daylight. Because it is hard to duplicate the
daylight wavelength, look for a CRI rating as close to 100 as possible. We
have obtained really fine results with a lamp system using a fluorescent
lamp with a rating of 98. We have found a weakness in obtaining yellow
saturation, which can easily be balanced in either Photoshop or Picture
Window. We have been found that the software of BetterLight produces a
wonderfully neutral gray balance across the entire scale.

Reproducing From Transparencies
Transparencies are very
high in contrast and need to be scanned by a scanner that has a very wide
range. For years drum scanners have had the distinction of being the only
scanning technology capable of reaching the full dynamic range of a
transparency. Today there are a number of non-drum scanners that come very
close. Besides the sharpness of the scanner's ability it all about dynamic
range.
Transparencies have
numerous problems. They were never created for capturing art and are
inherently non linear. That means its ability to produce a perfect gray
scale is almost impossible. When adding the anomalies of film processing
the results can go from not bad to disastrous.
Printing Fine Art
Fine art reproduction
differs significantly from photographic reproduction. Photography is
comprised of tonal shades, whereas, paintings are comprised of a blend of
color tones mixed to create the illusion of shades of tone. Being able to
reproduce the nuances of color is far more critical in Fine Art Printing.
Painters
throughout history have used very little black pigment, their shadows and
deep tones are comprised of rich color combinations. This differs greatly
from traditional digital printing.
Digital
Printing has traditionally used black ink to replace color in the shadows
and to enhance the depth of color. Often the technique used is called UCR,
which stands for under color removal. This process is used to reduce the
amount of ink layered down in the shadows. While a painter can layer
pigment, digital ink when layered pools, puddles, and blisters. This is
not a good thing. So the amount of ink used in the shadows and deep tones
must be kept to a minimum. Therefore, "the quest" is to increase
the amount of color density used in place of black. This is a complete
antithesis to the basics of digital printing. How do we accomplish this?
To
accomplish this, each color must reach the desired saturation at no more
than 70% of its density scale. This means that we have to cut back each of
the primary printing colors CMY. However, this is not possible with most
inks manufactured by printer companies, OEM's. We spent a great deal of
effort, research time, and capital to develop Symphonic Pigment ink. It
accomplishes this prerequisite. Let me tell you this was no easy task, but
well worth the results. Now we can reach the depth of color without
relying on black.
The Quest
For Rich Long Life Inks
There are several elements that contribute to longevity.
One of which is its ability to resist fading and another is the
concentration of the formula. To find a pigment that offers both longevity
and brilliance is usually expensive. Most inks are compromised with the
idea, “its good enough.” Symphonic Ink was made without compromise from
the highest quality long life pigments made with a very high
concentration.
Rip
Software
The Rip driver used to process the image is essential in controlling the
tonal scale as well as the saturation. It sets the parameters of amount of
ink used for profile making. For more information see Rip Info.
Color
Management
The control of making the right type of
profile is essential to quality reproductions. If you intend to make your
own, take the time to try different approaches with black generation
control. Here is where the control of Black Generation is critical in
making a profile ideal for Fine Art. Look in our area of Color Management
Theory for a understanding in UCR, GCR, and black generation.
