Dear [recipient's name]:

Our company has been working with your printing company for two years for the printing of all of our publications. In the past two months, several jobs that you have printed have not been satisfactory to us, in terms of quality. In particular, the colors and paper quality have not met our expectations or been consistent with what we had ordered.

I would like to talk with you so that we can discuss these issues and assure that future projects will be of the quality to which we are accustomed. Please call or e-mail me so we can speak further. I look forward to successfully resolving this issue and to again receiving the quality service to which we had been accustomed.

Sincerely,

[Signature]
