Purple haze... well green actualy

[gcaluna13]

I have something set somewhere that casts a pollen-green haze over my entire page when going to print.

I wasn't even aware of it until I set my prints (which are supposed to have white backgrounds)down next to new paper. That's how transparent the haze is, but it IS there.

Any Ideas?

Flush the bong water?

Thanks,
Cheech

What type of printer are you using? It's not uncommon for heat to have a chemical reaction with the paper that causes a colour shift,paper made from wood-based pulp without lignin removed goes yellow over time, with it being exposed to light and/or heat.

One way to find out what's causing it is to print each element separately, if it's over the entire page then it could be as simple as a box in the background that encompasses the whole page.

If you use Windows>Attributes, you can set different objects to non-printing, or you could try putting things on different layers and printing just that layer.

Of course, your other problem could be that your monitor isn't colour calibrated and that it looks white on the screen, and not your printer.

You can buy a Kodak Professional Colour Management disk, that comes with colour photographs included, and these photos are on the disk. It costs about 20 pounds. And if you buy a colourimiter, around 80 pound, this will calibrate your monitor, you can view the monitor against the printed images supplied by kodak, and print them out to see if you are getting the correct colours. Although what you see on the screen won't be the same as what you see on print, there will be a difference as one of the colours you are viewing are transmissive.

Thanks Eugene,

I really appreciate your help, but I think I got it figured out.

Under my color management setting in printer setup, "proof" was selected instead of "document."

Don't ask me how Proof creates a skim of greeness over the entire document, but there you have it.

Thanks again,
G.

Yes the proof would cause that. That is all down to your colour management. I'm sure if posted this on a "Printers" forum that someone could offer you a good colour profile to use with your printer. You can change your Proof settings with

Edit>Colour

Then you can change a host of settings, which if you use the colourimeter I suggested would save a profile and you could use that for printing, resulting in accurate prints all the time, as documents supplied from others have different colour settings, even embedded colour profiles in images.

But if you're not sure, what make/model is your printer, I could try to find out the best colour profile for you to use, but keep in mind, that when you send these to the printers they will most likely use their own colour profiles, unless you supply them or specify.

...color profiles can do some strange things to output, if your proof setup is not using a reliable printer profile then you can change the proof setup profile under the view menu, then choosing proof setup in the color management output would be OK as long as that profile is a valid one for your printer and paper type...

...if you have indesign manage the color on output ensure your printer driver is not color managing as well or you will get a double conversion. You either have the printer driver deal with color or indesign, but not both. Nonetheless color management on output is reliant on correct profile usage even when set up correctly...

..to add...

...proof setup is actually under the view > proof setup > custom, not edit > color settings as these are working spaces which are quite different from an output or proof space...

...so in theroy you can view how your working space will look on a given device, paper or printing press, this could then, in theory be simulated on your proofer...

...but again, accurate profiles are key and a calibrated monitor to achieve reliable results, and even then there is no such thing as a perfect match...

...that is without even mentioning spot color use...

Good points Andrew. I was under the impression that you can view any proof setup, but the actual Colour setting you have selected in

Edit>Colours

would be the one that is used when printing. I've said it before, colour management gives me a headache, there's so many things you have to look for and ensure...

I am waiting for a book on colour management in the post soon, so I'm still learning.

 

[apepp]

...yes, a headache indeed, a can of worms too when you dive into it, so many things seem to want to control color it's baffling where to begin...

...so many variables, paper used, whiteness of paper, humidity, temperature, skill of a printer, printing press used, ink manufacturer used, type of ink used (laser compatibility or not laser), lamination etc, etc...

...if it were easy we'd all be doing it probably...

...if we all only printed onto one type of controlled paper, using one type of controlled press, using the same inks etc, etc, then color management would most likely not be quite so daunting...

...i guess it is similar to painting a wall in room, color can look different to how it looks in the tin, nice and bright. Once on a wall you decide it doesn't look how you imagined...

...your mate then walks in and perceives a slightly different take on how you see it...
