Coated papers being more expensive, we expect higher quality from the printed piece. Gloss coated, which holds the ink high on the surface, will show any defect from inconsistent pre-coating, print head jetting and even inconsistent paper coating. Note that, even though we may not see a difference in surface coating, offset coated papers can come with inconsistencies that originate at the paper mill. If coating is not evenly applied across the entire paper machine, the roll or ream you receive will print and dry differently than the one before.

Knowing he color capabilities of your inkjet device is very important, but understanding the color capabilities of your press crew is critical.

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.
