slide3

Colortrac 3680e at 400 dpi v 24120 Flatbed at 400 dpi

Image is good

But Flatbed is sharper,

contrast is better

NOTE: Images viewed at 1:1 and screen copied

2003

slide4

Colortrac 3680e at 600 dpi v 24120 Flatbed at 600 dpi

Flatbed is sharper

Contrast is better

Image is darker

Interpolated to 600 dpi

NOTE: Images viewed at 1:1 screen copied

2003

slide5

Colortrac 3680e at 600 dpi v 24120 Flatbed at 600 dpi

Flatbed is sharper

Contrast is better

Definition improved

Interpolated image is not as clear

NOTE: Images viewed at 1:1 screen copied

2003

slide6

How interpolation is inferior to true optical dots ?

3mm

Interpolated to 600 dpi

blocky appearance

Scanned at true 600 dpi

- smoother

NOTE: Images viewed at 1:1 screen copied

2003

slide7

Why does the flatbed look better at 400 dpi ?

400 dpi - optical for the 3680e

400 dpi - similar but better,

improved lenses

NOTE: Images viewed at 1:1 screen copied

2003

slide8

What happens at 600 dpi,

600 dpi - optically interpolated for the 3680e

600 dpi - natural maximum optical

NOTE: Images viewed at 1:1 screen copied

2003

slide9

and at 800 dpi ?

600 dpi - natural maximum optical for 24120 flatbed

600 dpi - optically interpolated for the 3680e

800 dpi - natural maximum optical for 42160C

Absolute perfection!
