This is a tutorial on how to minimize printing anomalies like banding and odd color variations. Incidentaly, this tutorial covers some photo correction technique which can be very usefull for adding detail back to images.
Photoshop Version: CS2 (Can apply to Earlier versions up to Photoshop 7)
I have come upon a technique for reducing printer anomalies (Banding, color patches and ghosting) that is really quite simple.
When I say “banding” I mean where you visibly see color changes in a gradient or image as you can see here:
When I say “ghosting” I mean areas of light color around dark color areas which shows up when printing but not on screen. An example is shown here:
The main technique is to add enough noise. Adding noise to a gradient will reduce printer banding. This is also true for areas of solid color — adding a bit of noise can make the color print very even.
