Knowing he color capabilities of your inkjet device is very important, but understanding the color capabilities of your press crew is critical. Visually tweaking or modifying color on press is never an efficient or repeatable way to run production. Making your staff aware of their potential vision deficiencies will help catch color, as well as print quality issues, before they get to your customer. Here are some things you should know.
As inkjet moves into applications with high ink coverage and quality demands, users can run into some hard to diagnose problems. If you only focus on the paper and the print heads when trying to diagnose print quality issues, you could struggle for a long time looking in the wrong places.
Shade is important to inkjet color reproduction as the paper’s shade shows through the ink and can shift the ink’s colorant when applied to the sheet. Paper shade can affect all values of highlight, mid-tone and shadow areas of print.
Paper whiteness is particularly important in markets for which small text and readability is important such as book as well as magazine. For magazine images, the level of OBA’s in the paper can affect color reproduction accuracy of certain colors combinations.
Offset printing satisfies the majority of the production requirements for both catalogs and magazines. As marketers seek to increase ROI, you can start to make the case for shorter runs, versioning, hyper-localization, and personalization and then inkjet printing starts to become interesting.
While the conversion of marketing collateral from offset to digital may not be high, the value for digitally printed collateral is often much higher than other applications, typically driven by shorter run lengths, versioning and personalization. This has created excellent revenue opportunities for commercial printers who specialize in this area.
In this installment of “Let Data Drive your Print Quality Comparisons” Mary Schilling discusses the importance of chroma, how it’s defined within the context of print quality analysis and differences between inkjet and offset.
Mary Schilling discusses objective inkjet print quality comparisons and the benefits of a data-driven approach. Objective print quality analysis provides clear comparative data and removes all personal bias and visual subjective deficiencies when reviewing prints off competing inkjet devices. Inkjet beauty is more than skin deep!
Contributing author Chris Lynn provides and insightful explanation of “Apparent Resolution”: what it means, how it came to be and whether or not it matters for your application segment when evaluating an inkjet press.
In the previous post How to Make an Inkjet Sandwich I talked about the potential different ways that ink can react to a substrate when used in combination with other fluids such as primers or post-coatings. Those interactions make it critical to optimize all the fluids for your entire process, prior to linearization and profiling, to avoid print defects such as color to color bleed and coalescence.
