Staples® Copy & Print owns a high-end, multi-million dollar printing facility, with consistent quality control and color-correction standards. While Staples Copy & Print maintains as high standards as possible, it is still almost impossible to print and expect to see exactly the same color every day.
There are so many possible factors that can affect the color on your printed materials. The weather outside can play a part in affecting how the ink dries on the paper, and can change the color slightly. The paper delivered from the paper mill may be slightly brighter. The ink density and constant on-press fluctuations in color, printing press running temperature or blanket wear, could also affect color slightly. It is impossible to expect that any professional printer can produce exactly the same printed blue on two separate days. However, Staples Copy & Print does have high-quality controls to ensure as little variation as possible, especially within a single product order.
