Controller/rip effect on print


Active member
1. For dry toner, a controller, like Fiery, improves color accuracy/matching with monitor color, but does it improve definition, of fine lines for examples, help with color transition/banding, and produce solid color text (This is one of the problems we have with our printer)? Please tell me what other graphical features it affects.

2. There are rip software, which is a the graphical part of what a controller does (correct me if I am wrong), for wide format inkjets. Are there ones for dry toner printers, that can be an alternative for a controller?

In simple terms, a RIP (Raster Image Processor), converts the page description language into a raster image. As you say, that is the software function. Without the box, the best the rip software can do is send that raster image to the printer's internal processor to interpret and send to the print engine. So, any deficiencies in the printer's processor remain in the output. The box part of the rip is of course a computer dedicated to processing files. That takes the load off of your computer. But most important, the box has additional hardware and a separate cable that sends the page image directly to the print engine, bypassing the printer's internal processor. In theory, that image is superior to what the internal processor is capable of and takes full advantage of the engine's capabilities.

Although the autonomous car is not quite ready, a lights out print operation is something you can do right now if you have a comprehensive Print MIS (Management Information System). The advantages can put money on your bottom line. So what’s your next step? Link to Article
