Image color appears different on separate computers

[Tammy_UA]

Hello,

Someone created a 300dpi TIF image on their computer.  It was sent to me zipped via WeTransfer.  When I unzipped it the file had a pink background.  The image was suppose to have a white background.  The creator of the image double checked and said the background is white on his computer.  What can be the cause of this?

Thank you.

Screenshot please, preferably including the whole Photoshop workspace on your end.

The color calibration or management may be off on one of the computers. Hardware calibrators are very economical nowadays, but you can color calibrate the pink monitor to  get a white using  Mac Finder >> preferences >> display >> color. Windows may have something similar in the same area.

Also check you all use the same color management

edit >> color settings

If this does not resolve your issue, please post a screenshot of your color management settings on the pink computer, and anything else that may help us to help you.

No, this is not required and not a problem. There is no need for color settings to be the same. It should always display correctly regardless.

It could be a defective or corrupt monitor profile, but that is unrelated to document profiles and a separate problem. In any case it impossible to say without seeing what "pink" means. It could be anything from Quick Mask to a slightly off monitor white point..

The image appears less pink on the monitor. It’s when it prints that it is really pink.

Well, this is why color management was invented. This is why you use document profiles and printer profiles, and make sure the right printer profiles are used for the paper and ink. This can be controlled, but it requires standard color management procedures. Without that, it's all to the wind and anything can happen.

Thank you. Could you please give an example of setting up color management procedures?

Is image mode >> CMYK or RGB?  What values does your info palette show when you go over the white area. Can we please see a screenshot of your print settings?

[Tammy_UA]

The image mode is RGB.

I attached an screenshot of the white value.

We don’t print directly from PS. We use Wasatch SoftRIP.

Thank you.

[Mike_Gondek]

We did not get the screenshot, did you use this button?

What is the purpose of this print, are you doing a color proof to simulate a press , or they just need this printed to look good?

To give you a shorter more reliable response without a lot of questions, change the image mode to CMYK, save as a new filename and print if the values look good and the pink area is white.

[Tammy_UA]

Sorry I replied directly from my email and attached the screenshot there. The values for the off white color is:

H: 0

S: 2

B: 98

R: 250

G: 245

B: 245

This prints pink. And it’s not the whole image, it’s just the background.

Convert to CMYK as you are printing on paper not sending to a monitor, then look at the values. Send CMYK to your printer, not RGB.

in RGB you need the colors to be equal to have pure white, so that color does have a very slight pink cast. When you convert to CMYK you will likely have too much magenta for a  neutral white

CMYK is different and because of inks hues/impurities and paper, you want your highlight for example to be 5c 3my 1k (darker or light depending on your image), basically cyan is slightly higher, and MY are equal to each other.

Thank you

Color settings most certainly make a difference when view >> proof colors enabled.

As others have said,  the color calibration could be off on one of the computers.  its really easy for that to happen.
