Hello and thanks for your question. I am a licensed printer professional, and I will be assisting you today.
Open up a blank image in Photoshop or any software which you use for editing (with a white background) and hold up a piece of your high quality printing paper.
Does the white of the screen match the white of the paper ?
You have to try changing the brightness and contrast of your monitor to match the actual white paper.
If by adjusting the brightness and contrast doesn't matches your monitor screen.(rare cases)
Then you will have to purchase a colorimeter which will allow you to calibrate and profile your monitor so that the white point and every color points along the spectrum is consistently and dependably adjusted to be where it should be.
For more information on this, please refer to this guide: http://www.colorwiki.com/wiki/How_To_Get_My_Monitor_To_Match_My_Printer
