I was wondering what format you are using when you export to a Roland Verscamm printer.
RGB or CYKM
Ever once in a while I run into the problem of creating something using a color that includes either a red or blue that the printer won't print correctly.
When creating graphics are you only working with RGB colors?
The whole issue of color management is very interesting and also difficult to understand.
I am using an Oracal vinyl and have used the settings they suggest.
Thanks Jimmy

Isn't it so that a postscript printer/RIP (like VersaCamm/VersaWorks) handles CMYK data without converting it, while a non-postscript printer (GDI, desktop printers) must receive RGB data, that then will be converted in the printer before printing CMYK?So, there'll be a CMYK - RGB - CMYK conversion when using CMYK and a GDI printer. For postscript though; CMYK - CMYK.
As we all know RGB has a much wider gamut than CMYK, so the colors we can create and display on screen, has no chance in hell being printed without a "downgrade" to the CMYK gamut. So what's the point designing something that won't print anyway. Isn't it just going to make it more difficult?While designing in RGB mode, do you check how the output will look by using the Proof color function in Draw. Is it on all the time or do you check now and then? If it is on all the time I can understand there is a point using RGB, if not please explain.

Maybe on 6 color machines there is some hope for additional color range? But I'd think only if the extra 2 hues are orange and green like Hexachrome.
If just Light magenta and Light Cyan are the extra inks, still really only CMYK, just smoother shades in 2 channels in the 0-20% range.
Personally I'm comfortable with CMYK, mostly out of habit. AND because I output to 4 color devices only. I'm happy with the colors I get, to be honest. Red looks like red, black is black. etc.
If something "looks wrong" on my printed examples, I know what channel to adjust because I can see the 1:1 connection between the print heads and the artwork. In RGB... it's not so clear how to tweak an image in order force a specific head to output more ink.
With practice, prepress folks that work in CMYK can look at artwork and predict which CMYK inks are used for a hue, then later they can predict what percentages of each are used too. Traditional Oil painters probably look at color this way too, when mixing inks.
