Print Mode Comparisons
(real world observations)
¾
The 1x4 cartridge set running @ 6-pass print mode uses approximately the same
amount of ink as 2x4 cartridge set running @ 3-pass print mode.
– both modes use same amount of ink (since both are 4 color) for the
same image printed; but because 2x4 is 30%+ faster, the ink
consumption is therefore 30% higher for the same printing time period.
¾
The 2x4 cartridge set running @ 3-pass print mode is ~45% faster than the 1x4
cartridge set running @ 6-pass print mode.
- Image quality is a little different between 2x4 operations and 1x4
operations.
- 2x4 @ 3-pass is 30% faster than 1x4 @ 4 pass
- 2x4 @ 4 pass is roughly 35% faster than 1x4 @ 6 pass
- Print time also depends on the RIP and connectivity type used (parallel
direct or via SEH/Built-in print server).
¾
The 1x4 cartridge set running @ 6-pass print mode has significantly better quality
than the 2x4 cartridge set running @ 3-pass print mode.
– Also, the 1x4 @ 6-pass has better quality than 2x4 @ 4-pass as well
¾
The 1x8 cartridge set running @ 6-pass uses 20-30% more inks vs 1x4 cartridge set
running @ 6-pass but print time is about the same
– Across a broad range of tested images customers have observed an
increase of ink usage anywhere from 5% up to 47%; dilution ink (i.e. light
Mag/Cyan and medium Mag/Cyan) consumption largely depends on
gradients/color ranges printed in a given image.
- The increased ink consumption average (going from 4 color to 8 color
printing) is approximately 27%, but it really depends on the colors in the
image. The lighter density fills (especially with people’s faces and
light/gradual gradient changes) will use more dilution inks – overall
saturation levels need to exceed 200% to peak the higher ink usage
levels though.
- Observed image quality in the 1x8 cartridge set is superior over both
1x4 and 2x4 cartridge sets.
