One of our consultants uses a really thin line weight and was coming out so light you can barely see it. We use KIP Request and to send PDFs to our printer. We recently got a new controller installed for our KIP 3000 and I believe our KIP PrintNET settings got reset in the process (it was printing fine before the new controller). I was told that changing the Dither Mode under KIP PrintNET / Printer Config / Monochrome PDF Processing would do the trick. It helped but once I changed the Min Feature Size setting to 2 and Dither Mode to Tempered it printed our files and our consultants the most accurate. The only issue is that our thinnest line type and 2nd thinnest look almost the same now. The thinnest line we use should be semi opaque but isn’t coming across that way as much as it should.

There are many Dither Mode settings to choose from (Default, Line, Mix (Photo), Mix (Line), Tempered, Stochastic, Double Dot and All Black). So my question is, what do these different settings do/mean. Or, what settings do you use under Monochrome PDF Processing (Dither Mode, Min Feature Size, No Transparency settings).

Any input would be helpful, thanks.

• Standard – use default dither pattern that is shipped with the KIP Printer
• Printer – use PDF dither patterns that have been configured within KIP PrintNET
• Line – dither pattern that is designed for image data consisting of lines
• Mix (Line) – dither pattern that is designed for image data consisting of grayscale / photos / lines with an emphasis on lines
• Mix (Photo) – dither pattern that is designed for image data consisting of grayscales / photos / lines with an emphasis on grayscale / photos
• Tempered – From Ghostscript 8.x the well-tempered screening was introduced which gives much better quality for half-tone images.
• Stochastic – http://liris.cnrs.fr/victor.ostromoukhov/publications/pdf/SPIE99_StochasticClust.pdf
• Double-Dot – dither pattern that is designed for weak image entities such as lines
• All Black – removes all dither patterns and converts all “color” to black

PDF Dither Mode: Output of monochrome, PDF image data can be altered based on the original image type.

PDF Min Feature Size: Controls the size of printed entities or features. All aspects of small features will be adjusted with this setting. Settings range from “off” to 3 with 3 enlarging all small entities.

PDF Transparency: Transparency in PDF files refers to objects on a page, such as images or text, which are transparent or ‘show through’. Transparency is typically used for shadow effects, to lighten (parts of) images so that the text on top remains readable, to make objects fade into another object or to create a tint of a certain color. Settings enable this or disable this function. Note: Transparencies can cause significant print performance issues.[url][/url]
