More and More Ink Savings
Demand for ink savings – be it for economical or ecological reasons – was never stronger.

Printers need to decrease direct costs to increase their margins. To achieve that, in most cases, they are willing to allow for a non-significant color deviation in counterpart of significant ink savings.

Thanks to Alwan's multicolor technology, we were able to achieve these 2 goals.

The new "Minimum TAC and Ink Usage" (MTIU) feature offers ACH users the ability to choose a new strategy for calculating device values, which is Minimum TAC centric instead of being Maximum Black centric. Users define the additional ∆E they are willing to accept on the "Ink Saving Boost” (ISB) slider ranging from ∆E 0 to ∆E 2.

Production tests with offset and digital printers have confirmed that up to ∆E 2, differences with Dynamic Maximum Black (DMB) 10 separations barely show any visible difference once printed while delivering up to 18% additional ink savings for some files.



More and More Accuracy
∆E00 is the standard ∆E formula used by the new ISO standards and generally by the graphic arts industry.

∆E00 is now an option in DVLP Generation parameters that has to be chosen manually, as it delivers slightly different results than ACH default ∆E 94 formula.

It is highly recommended to use ∆E00 formula for 2 reasons:

  • It will give you more accurate colors and lower ∆E when print is verified using ∆E00 based conformance assessment such as with ISO 12647-7; and
  • ∆E00 formula delivers up to 3% more ink savings when used with MTIU and ISB.
