Scanned on a high-end Linotype-Hell¿ 3800, these are TRUE 32 Bit CMYK separations of extraordinary quality. Each image has been meticulously color-corrected, retouched, and sharpened by prepress professionals to insure flawless color reproduction right off the CD. Vivid Details images are ready to use instantly in all major desktop publishing software programs without time-consuming conversion. Each color volume is comprised of three CD with two resolutions per image. The CDs are manufactured in ISO 9660 format for Macintosh¿ & Windows¿ compatibility.

PRINTING
Much has been written about "SWOP Coated" being the standard set-up for printing on coated stock. This is erroneous. S.W.O.P. stands for Standard Web Offset Printing, and was devised for magazine reproduction at 133 lpi (halftone line screen) on a lightweight book stock of average quality. SWOP does not produce optimum results for high-quality offset printing.
Vivid Details¿ images are optimized for high-quality offset printing on a sheetfed press using coated stock with a halftone screen frequency between 150 to 200 lpi. Our files have a total ink coverage from 300% to 320%. Shadow areas have a 95% to 97% density, while the highlights are set at a 3% to 5% dot.
If your job is running on a web press, or you plan to use a more absorbent stock, like newsprint, you'll have to make adjustments to the file. Changing "Separation Set-Up" and "Printing Ink Set-Up" in Photoshop¿ only takes affect when an image is converted from RGB to CMYK. If you want to utilize these Photoshop¿ preferences you must first convert Vivid Details¿ CMYK image to RGB. Next, change the separation and/or ink settings, and finally, reconvert the image to CMYK.
A Vivid Details¿ image contains TRUE CMYK values, and has already been color-corrected. So this double conversion process is actually more color stable and accurate than converting an original RGB image because color shifts and out of gamut colors are avoided. And since Vivid Details¿ has a TRUE black, not an interpolated black, more detail will be retained in the shadow areas when using UCR (undercolor removal) or GCR (gray component replacement).
Typical printing specifications are as follows:
SHEETFED COATED (Vivid Details¿):
Dot Gain 12-18%, Ink Coverage 300-320%, 3-5% Shadow & Highlight
SHEETFED UNCOATED:
Dot Gain 15-20%, Ink Coverage 270-290%, 5-7% Shadow & Highlight
SWOP COATED:
Dot Gain 15-20%, Ink Coverage 280-300%, 5-7% Shadow & Highlight
SWOP UNCOATED:
Dot Gain 20-25%, Ink Coverage 250-270%, 5-10% Shadow & Highlight
These percentages are averages. Be sure to ask your printer for specific recommendation before you produce film negatives.
MEMORY REQUIREMENTS
If you are currently working with desktop publishing software like PageMaker¿, or QuarkXPress¿, no additional memory is required to use Vivid Details¿ images in your layout.
If you plan to manipulate an image with an image-editing program like Adobe¿ Photoshop¿, refer to their user manual for RAM memory, hard disk space, and virtual memory requirements.
IMAGE MANAGEMENT
Stretching or shrinking an image changes the effective ppi because the number of pixels doesn't change when an image is resized. If a 300 ppi image is enlarged to twice its original size, the same number of pixels are forced to cover twice the area and the ppi is reduced to 150. Conversely, if the image is reduced, the ppi is increased and you may end up exceeding the imagesetter's capability.
As a general rule, it is recommended to have the ppi of an image set at twice the intended lpi (a 2:1 ratio). As an example, if you are creating a brochure, which typically requires a 150 lpi (halftone line screen), then the image should have 300 pixels per inch at its final output size. The minimum acceptable lpi to ppi is a 1:1.5 ratio. As an example, if you require a 150 lpi, the minimum ppi for that image is 225 at its final output size.
To achieve the largest possible output size, use the minimum lpi to ppi ratio of 1:1.5. Refer to the following examples:
9" x 12"
use at actual size 100% - 200 lpi - 300 ppi
12" x 16"
enlarge the image 133% - 150 lpi - 225 ppi
13.5" x 18"
enlarge the image 150% - 133 lpi - 200 ppi
18" x 24"
enlarge the image 200% - 100 lpi - 150 ppi
21" x 28"
enlarge the image 233% - 85 lpi - 127 ppi
PHOTOSHOP¿ TIP
Before you manipulate a Vivid Details¿ image in Photoshop, change CMYK Composites to "smoother" instead of "faster" in the general preferences dialog box. This setting prevents Photoshop from converting the color information to RGB so actual CMYK values are maintained.
