Help my pictures are red!

[sheila3]

Hi all! New to dps. Question for you. I use Adobe photoshop. Always worked well for me.
Yet recently my pictures look good on monitor yet come out of printer warmer and lots of red. I know monitor and printer are fine. Tested them with old HP hardware and those pictures came out fine. So is problem in Adobe? And how do I fix it? Thanx so much!

Your printer and monitor may not be totally fine. You sometimes need to calibrate your monitor to your printer.

Also make sure that, before doing anything you intend to print from that printer, you convert to CMYK instead of RGB. That could be part of the problem.

hmmm so converting from rgb (ie adobe rgb) to cmyk is recommended before printing usually? that might be the issue i've had in the past printing as well. i've usually gotten around it by matching color profiles from my program to my printer but this could be a help

It sounds a b it like funky colour management check your operating system and also photoshop to see whats going on. Not sure if you havent already tried but do you have an ICC profile for your printer from the manufacture and is it linked to your printer? as it may have a different profile linked so there could be a miss match going on if your telling it use a different colour profile.

You can do it by manually matching profiles, but many printers dont HAVE profiles. If youre doing ANYTHING for print, ti should be in CMYK and, if possible, in the printer's profile for CMYK.

awesome thanks for the tip!

Thanx so much for the help! Will try it out

It is a good tip will give you a good idea of how your photos will print out by converting to CMYK and as some colours dont carry over from RGB it will allow you to edit colours that are funky.

Just check you have the postscript printer driver for your printer installed as the standard PCL drivers will convert your image to RGB and back to CMYK.

I thought most printers today used the sRGB profile, and definately not CMYK, especially not those aimed at the home consumer market.

From wiki:
"sRGB is a standard RGB color space created cooperatively by HP and Microsoft in 1996 for use on monitors, printers, and the Internet."

Yup your right most modern inkjet printers and Labs use sRGB profiles (not to be confused with Adobe RGB) the printer does the conversion to CMYK. You can soft proof your work on screen using their profiles if your worried about colour errors. Laser printers that use postscript drivers will support printing CMYK as will commercial printers.

Usually I agree its best to stay in the sRGB colour space it may be smaller but most LABS use it and you know your files and colours will be correct.
