The document discusses the challenges of achieving accurate color when printing due to the many variables involved in different printing processes and output devices. It emphasizes that ink optimization solutions should not only focus on ink savings but also maintaining low color variation. An average delta E of 0.5 or less is considered good for color transformations. It argues solutions should take a holistic view of optimization, not just ink savings, and consider other factors like conforming to color standards, dot gain compensation, plate curve maintenance, and reporting to ensure quality and efficiency for both conventional and digital presses.
