Most likely there will be slight variations. That is why we generally say NO. We use a 4 color printing process, whereas your printer at home uses three colors. This is what create the variance. Even our images proofs can have a %5 discrepancy when printed on the final process. Please contact us ahead of time to let us know if your job is color critical. We can provide you with a print to make sure that you are happy with it, before it goes to final press.
