I have to print CDs which are pure Orange in colour. Using R = 255, G=127,
B = 0 gives a pure orange display, however whatever I try to do to correct
the problem, the output is more like a Peach colour (pastel orange?) Is this
an unmatchable colour using an inkjet? I have a similar problem with primary
red - it is more like a salmon colour. Anyone know if this is an unsolveable
issue, and I have to tell my client that's as close as it gets.

Drawing on an orange background on the screen is not the same as spraying
ink onto an already orange surface. On screen, it shows the colour as a
perfect cover. In practice, spraying ink onto an orange surface allows
the orange to show through.

Try setting an orange layer of 100% opacity then draw on a new layer with
an opacity set to show similar results to what you get when printing.
This will allow you to work on screen and see what the actual output will
look like, approximately.

You're best bet is probably to assume a black and "white" image where the
orange surface will be your "white"

I thought he meant the cd's were orange to begin with also, but after
reading it several times, I think he meant what he wants to print is
pure orange and coming out pastel.

correct me if im wrong as this would be a different ballgame

You might well be right. A more carefull reading does seem to indicate
that. I probably got caught out by the fact there's a spindle full of
orange label DVDs right in front of me now. Amazing what a little
auto-suggestion can do to the thought processes <g>

It looks like the OP needs to make sure his screen and printer are set up
properly with profiles or whatever. With a colour difference as wide as
he implies, I'd think that either he's got some very poor/cheap ink in
that printer or, more likely, the screen is not set up correctly., ie too
dark so what looks like orange on his screen is actually salmon pink.


There's a page at http://www.photoscientia.co.uk/Gamma.htm which goes into
screen gamma setup and gives a fairly accurate example of what I think is
happening to the OP as regards the orange.

Thanks for the suggestions, you are correct in that I am printing on Ritek
white printable CD's. I am ignoring the screen colour in this - and in fact
today I tried the same thing on my Epson 950 and got the same problem. It
looks like orange until you compare it with the output from my Xerox 8400 or
a colour laser print. It then has a pastel tinge to it. I'm starting tom
think it could be a colour space problem in that Epsons print using RGB, an
if you look at the colour gamut compared to pure CMYK it doesn't quite reach
the saturation needed. (Adobe have a page on this on their site). I think it
might need a different driver to get what I'm looking for - can anyone help?
P.S. I print around 2500 disks a week, both CD and DVD on various types of
media using these Epson R300/200 printers. The only problem is the plastic
CD trays wear out!

Martin

Great info Dave. I know I visited that site within the last couple
years. Overall my gamma was fairly accurate with the adobe gamma but
the bright grays needed to be neutralized and my blackpoint was a bit
off as well....

I ended up using a 2.0 gamma and my contrast was set too high and
blowing out the high shade grays with color. Overall I got things
neutralized pretty well

thanks again
 
Looking at purchasing the R200 for DVD's and CD's hows the quility?, and what
DVD's do you print on?

Thanks
