“Res” mode

Besides being useful for RGB output, this mode is recommended for scanning line art for pre-

press output.

1 • Type in the desired Res (output resolution) in lines/mm or lines/inch and press the tab key

to confirm.

2 • Type in the desired Output Size in millimeters or inches and press the tab key to confirm.

3 • If desired, you can also change the Quality F

actor .

The Scan Resolution and File Size will be calculated automatically.

• If you type in an Enlargement, the Output Size is calculated automatically,

and vice versa.

• In flatbed scanners, the maximum scan resolution is highest down the

center of the scanner bed, and decreases as you move toward the sides. If a

yellow warning triangle appears in the Scan Setup window, it means that

ColorQuartet is interpolating the scan resolution to achieve the required

value.

• NOTE: To prevent the crop frame from being grossly distorted if a much

greater or smaller value is typed in for Output Size, ColorQuartet preserves

the height-to-width ratio of the drawn crop frame if the first new value

entered results in a change of 30% or more in size. You can then type in the

second value and the crop frame will be resized. If you type in values that

result in a change of less than 30%, the crop frame will be resized to each

new value immediately.

For line art, use the same value as the dpi with which the image will be

output. For example, if you will be outputting the image on a 600-dpi

laser printer, type in 600 lines/inch.

For line art, always set the Quality Factor to 1.0.

Note that increasing the Quality Factor will also increase the File Size,

but not the Scan Resolution.
