Create multiple profiles for the same paper to manage ink use for your client’s range of acceptable color levels. Make the profile name part of your job definition.
Don’t make designers guess about color matching or papers that work well with your press. Create tools to give designers and print buyers an objective understanding of your press quality on different media.
Dust and Downtime
Uncoated papers with uneven surface formation can generate dust. Dust can buildup on paper transports and print heads causing jet-outs, reduced print quality, increased maintenance costs and downtime. If dust concentration is very high, it can have health consequences for workers – more downtime!
More inkjet presses can now print on offset gloss – but test carefully. The ink may adhere just fine, but gloss stocks can slip more easily (especially roll-fed) so check registration of fine images and rich blacks.
Most aqueous inkjet devices will have plugging and registration issues with rich black text at 9pt or smaller. If you need fine print, test the density of plain K ink and minimize the use of CM&Y. Some OEMs offer high density black.
If you see banding in continuous solid colors, ask the designer if “mixing up” that continuous solid is possible. Adding random patterns to large solid colors makes cross process print head density shifts less visible when multiple heads across the web are used to produce the solids.
The wrong drying configuration on an #inkjet press can torture the paper without properly drying the ink. Learn about the best drying options to match your type of work, ink type and coverage.
Don’t blindly accept the DFE bundled with the press. Ask about color management, variable data and file handling features of the DFE. Consider all of your DFE options and find the best fit for your workflow.
Compare Costs of Complete Solutions. Don’t conduct TCO or eliminate press options until you have configured a complete solution. An “expensive” press may look reasonable once you configure the “bargain” press with drying, priming, turn-bar, premium ink, software and finishing. Compare fair!
A different profile is needed for each paper AND the press settings it will be run under. Speed, TAC and resolution factors can all affect color chroma, density, graininess, small text clarity and line raggedness. Differences at top speed can be dramatic on some presses.
