Blues - A blue and white proof that shows actual layout, image resolution, fonts, etc. If accurate color is important you should see a color proof that was output on the actual press on which the job will run. The Match Print will show you the exact color that will print. If it does not show the color you want, the necessary adjustments to the printing press, or digital files can be made before the entire job is printed.
Proofs cost money, so take into consideration how important it is that the color is accurate.
Business cards probably don't need a match proof, but a black and white laser print to know that the files remained intact is still a good idea. 20 Bray Farm Ln.
