Previewing and scanning reflectives
Reflective originals are ones that are opaque, such as photographic prints, artwork done on
paper or cardboard, printed matter, etc.
• In general, the scanning procedures for reflectives are the same as for transmission originals
(transparencies). Just be sure to choose Reflection in the Pr
eview Setup and Scan Setup win-
dows.
Automatic shadow setting
If you want to make sure that the shadow point of a reflection scan is set to the darkest possible
value, activate
Auto Shadow in the Auto Setup window, which is accessed from the Highlight/
Shadow window. The actual value achieved will depend on the CMYK pr
ofile you are using.
Scanning bulky objects
Books, bulky originals and three-dimensional objects can be scanned with the lid of the scanner
open if necessary.
Rescanning printed matter
If you want to scan an image from printed matter, you should descreen it to blur the existing
halftone dots. Otherwise, you may get an unwanted pattern in the scanned image, called Moiré.
1 • Activate the Descreen check box in the Scan Setup
window.
2 • Type in the scr
een frequency of the original being scanned. (This can be determined with a
scr
een gauge.)
ColorQuartet will automatically calculate an appropriate level of blurring to remove the screen
dots in the original.
